Polyester Encapsulated Page Binding *Part Two: The Components

Polyester Encapsulated Page Binding *Part Two: The Components

This past year, the Preservation Lab was recruited to conserve the Public Library’s scrapbook of Althea Hurst.
Scrapbooks are complex library materials.  They are conduits to stories told through the use of collections of ephemeral materials (a.k.a. materials meant to be thrown away and not meant to last), such as newspaper clippings, letters and postcards, and maps.
Due to their collection of content, scrapbooks usually are bursting with problematic preservation issues.  Often, fragile pages hold stiff, brittle, or heavy parts that are adhered and folded.  Components are frequently found layered and overlapping.  These parts are filled with information and are intended to be handled and experienced; however, as the parts become fragile with age they are nearly impossible to touch without causing damage.

In most situations, it’s often best to digitize an object and protect it by storing it in an enclosure. I often recommend patrons reference the digital copy rather than handling the physical object.  Alternatively, if an object will be handled (and the importance of the object warrants conservation treatment) another solution is to support the pages by encapsulating them within clear polyester film.  The polyester film encapsulations are then bound into an encapsulated page binding.  This format help preserve the parts in the author’s intended order, however, this course of treatment must be carefully considered as it can sometimes be an invasive solution if disbinding is required.
In the case of the Public Library’s scrapbook, the scrapbook had been previously reformatted by a prior owner due to its poor condition.  At some point in the object’s history, each page and cover had been separated from the binding and stored in non-archival plastic sleeves to protect the pages from breaking.  Oversized rubber bands held the album in two manageable stacks.

When the library received the object, the pages were in dire need of stabilization before it could be digitized and also needed improved storage.  Because the scrapbook was already disbound into pieces (even the covers were detached) an encapsulated page binding was selected as the most fitting option for storage.  The local historical importance of the scrapbook warranted full treatment.

Being a novice in encapsulated page bindings, I reviewed a few binding structures and wrote about my discoveries here.  I settled on constructing a modified screw-post binding to fit the needs of the Public Library’s scrapbook.
Now armed with a direction for constructing the album structure, the next challenge was:
How do I encapsulate a scrapbook that houses a variety of adhered material, such as pamphlets, postcards, letters, maps, and more, and still make the parts accessible?

Encapsulation Techniques

To determine a solution for preserving the arrangement of parts, I researched various methods of welding paper, polyester film, and spun bond sheets of polyester webbing to encapsulated pages.  I compiled the methods into a model binding for reference in preparation for treatment.
Below are a list of experimental solutions for housing and encapsulating the scrapbook’s multiple parts.   Many of the techniques were utilized in the final treatment, as you will see in the photographs below.

1. Traditional Encapsulation

  • This technique was used to fully encapsulate scrapbook pages overall, or to encapsulate removed single sheets that needed extra support
  • Pages or parts were sandwiched between polyester film and ultrasonically welded on all four sides:

traditional

  • Gaps along the corners were left to encourage air exchange and to prevent buildup of acidic off-gassing of the historic materials.

2. U-sleeve: welded on 3 sides for top edge access

  • Useful for items that may need to be handled outside of the plastic and are thick or heavy

Usleeve

Hinged U-sleeve allows access to the card as well as stability for storing next to the envelope.

 

3.  Polyester sheets welded on two parallel sides

  • Could potentially be helpful in the right circumstance for thin items that may need to be handled outside of the plastic. Two access points are helpful for reducing static cling and suction, however, items may accidentally slide out more easily (see next technique for a similar yet preferred method).

4.  L-sleeve: welded along the left side and bottom edge (in the shape of an “L”).Lsleeve

  • Alternative technique to the U-sleeve for storing parts that may require future handling.
  • An L-sleeve can be welded to one side of an encapsulated page binding with an ultrasonic weld after the L-sleeve is created.
  • For thicker materials, an additional small weld along the bottom right edge is helpful to prevent materials from sliding out of the sleeve when the page is turned.

5.  Spot welds: heat or ultrasonically welded

  • Technique used to hold materials in place and prevent them from sliding within an encapsulation

spotweld

6. Thin overlapping attachments

  • Overlapping parts that need to be kept in a specific composition can be carefully removed from the page by a conservator and individually encapsulated.  The encapsulated components can then be welded to the upper sheet of the polyester page using a variety of techniques to preserve the original orientation.
  • Using these techniques allows access to all the components on a page that would otherwise be inaccessible in a traditional encapsulation, and keeps the author’s intended composition.
  • Parts must be oriented and welded to the upper sheet of polyester before creating the finished encapsulated page, i.e. before encapsulating the lower sheet of polyester to the upper sheet.

7.  Hollytex hinge

  • A strong synthetic hinge (made from spun-bonded polyester) that is welded to the clear polyester sheets with ultrasonic welding.
  • Useful for easily viewing the front and back of  overlapping parts or loose bits.

  • Usu Mino tissue is welded in between two sheets of polyester
  • The extended Usu Mino hinge can then be brushed with paste and adhered directly to a paper leaf.
  • Useful in other applications, for example preserving loose components in paper textblocks, such as pressed flowers or handwritten notes.

9. Polyester four flap attachment

  • For small but thick objects
  • To secure thin components with multiple parts on top of an encapsulated page while still allowing full access

i83079427_1015_D14N_2_2

10. Paper spacers

  • Strips of acid free paper can be placed within an encapsulation to prevent smaller components from moving within larger encapsulated pages.
  • The paper space holders are visually pleasing so the viewer is not distracted by the page below.
  • Static holds thinner sheets in place
  • Thicker textblock leaves may need to be spot welded in-between the document and the paper strip

13. Welding polyester film to Vivak

  • Even the cover contained an attached component!
  • As per a request by the curator, the original cover was incorporated into the new binding with reversible methods.  The original cover was hinged into a sink-mat package that was sandwiched between a cloth covered mat and a sheet of Vivak.
  • After a bit of experimenting, a polyester L-sleeve was ultrasonically welded to the Vivak “pastedown” so the original arrangement could be preserved

Fun with PhotoDoc – Edition 1

Fun with PhotoDoc – Edition 1

Since I am the conservation technician who carries out most of the photographic documentation in the lab I think that pretty much all PhotoDoc is fun.  With all the different tools in the toolbox it really doesn’t get much better than when you get to bust out the ultraviolet radiation to reveal something that is otherwise not so obvious under normal illumination (like a stain, handwriting, etc.).  And then when you can transform those normal and UV before photos into a gif…well, that just makes for a fun Friday, if you ask me!

classphoto_uv_gif
This photograph is part of the Henry R. Winkler Center for the History of the Health Professions collection and arrived in the lab with the original glass broken and partially attached to the photo. It is obvious under normal illumination that the photograph endured some kind of spill or water damage, but under UV florescence you can better make out the path that the water or perhaps beverage created and even note splotches of possible mold damage (which flourese purple).  Now that’s it’s photographed I’ll turn it over to Ashleigh, our conservator, to determine what’s happened to this poor thing and the best course of action when it comes to treatment and storage.

Digital Print Crash Course

Digital Print Crash Course

For 3 days in late October I joined a group of 15 conservation and archive professionals from as far away as Germany, Mexico City and the Northwest Territories of Canada for the “Identification and Preservation of Digital Prints” workshop at the Image Permanence Institute (IPI) at the Rochester Institute of Technology.
We learned about what curators might consider to be digital prints, what types of digital prints can be found within a collection, what their greatest vulnerabilities are, and how to differentiate between them. The workshop focused predominantly on the three most common types of digital prints: dye-sublimation prints, created through a process which uses heat to impregnate a surface with color; electrophotographic prints, which use toner-based colorants; and inkjet prints. We also discussed the best types of enclosures for storage, and how to use naming conventions to help collection curators and conservators identify these objects so as to best house, store, conserve and exhibit them.
Dye-sublimation prints are the least common of the three main types. The analog version of the process was invented for the textile industry and the digital version continues to be used to print images on fabrics as well as photo gifts like mugs. It doesn’t require liquid chemicals so it’s also popular for ID photos, photo booths, and instant photo kiosks in drugstores.  Generally speaking they can be stored and handled using the same guidelines as chromogenic prints as their vulnerabilities are similar. Light can cause fading over time, very high heat can cause bleeding. Most importantly though, while the clothes and mugs are obviously washable, the photos can delaminate in water, as shown below.
Dye-sub delamination
Dye-sub delamination

Almost everything printed on a copier or a laser printer is an electrophotographic print. They are ubiquitous in the documentation surrounding cultural heritage collections, if not in the collections themselves. The printing process is similar to that of photocopiers, though nowadays the image comes from a stored digital file rather than creating a photographic reproduction of an image. These kinds of prints are fairly stable. Though they can sometimes transfer with heat, or crack or abrade, their greatest vulnerability is the paper they are printed on, which can be almost any type of paper imaginable. In general they should be handled and stored the same way photocopies are stored and handled.
Inkjet prints show up as documents and ephemera as well as in the form of photographs and fine art prints. They can be made up of a broad range of papers and inks, many of them proprietary, which means it may be difficult to identify them accurately and their sensitivities to light, water, pollution, etc. can vary greatly. In general they are the most unstable of all the types of digital prints and therefore require the most care and attention for preservation efforts. We experimented to see how different inkjet prints responded to abrasion and exposure to water. From these tests we could see that even light friction or a tiny drop of water can be damaging to some types of inkjet prints. For a generalized approach to housing and storage of inkjet photos and art prints IPI recommends handling with gloves, using polyester enclosures and interleaving (paper enclosures can cause losses or burnishing), mounting with window mats, using UV glass when framing, and monitoring any exhibited prints closely throughout the exhibit. IPI’s handy mini-poster, Tips for Handling Inkjet Prints can even be printed out and included in enclosures.

It became very clear during this workshop that the term “digital print” can cover a dizzying array of objects. Curators, collectors and conservators like to have more specific descriptors for the media they are working with. For most purposes differentiating between electrophotographic, dye-sublimation, and inkjet prints in documentation is sufficient, but conservators in particular would benefit from even greater detail such as, “dye inkjet print on uncoated paper.” IPI strongly recommends that when new acquisitions are made a detailed document such as Martin Jurgens’ “Datasheet for Documentation of Digital Prints” from his book, The Digital Print: Identification and Preservation, be completed whenever possible.
Along with a very handy pocket microscope, digital print sample set, a color copy of the freely downloadable IPI Guide to Preservation of Digitally Printed Photographs, and a binder of the workshop’s Powerpoint presentations, IPI provided us with a tour of the online tools they have created. Their Graphics Atlas website, http://www.graphicsatlas.org/, is particularly useful for identifying different types of photographs and prints, and the DP3 (Digital Print Preservation Portal) website, http://www.dp3project.org/, is an excellent resource for information on preserving digital prints. While visiting I also purchased a copy of Meghan Connor and Daniel Burge’s book, The Atlas of Water Damage on Inkjet-Printed Fine Art, which I found informative. Seeing how a pocket LED work light like the Larry light could be used to generate different angles of light to help in print identification on the fly was extremely helpful too.
I can’t recommend this workshop highly enough. I learned a great deal over those three days in October. I am very grateful to the Image Permanence Institute, the Ohio Preservation Council, The Andrew W. Mellon Foundation, The Public Library of Cincinnati and Hamilton County, The Institute of Museum and Library Services, and my colleagues at The Preservation Lab for helping to make my attendance possible.

Nineteenth Century Buddhist Religious Treatise

Nineteenth Century Buddhist Religious Treatise

Palm leaf manuscriptIn August of this year, the Lab received a Palm leaf book from Archives and Rare Books library during one of our usual monthly meetings. This item was brought to the Lab to receive a new enclosure for a better long-term preservation storage and easier access. Along with a new enclosure, the Lab was asked to create two surrogates of one of the original Palm Leaves for classroom use.  Under the direction of Ashleigh Schieszer, lab conservator, technician Chris Voynovich constructed the housing working closely with Catarina Figuierinhas who created the surrogate leaves.
Palm leaf

Creating Surrogates

In order to create an accurate surrogate of one of the Palm leaves, the Palm leaf book was taken to the University of Cincinnati Digitization Lab to be photographed with a PhaseOne Reprographic System. This system includes 60 MP PhaseOne digital back, DT RCam with electronic shutter, Schneider 72 mm lens, and a motorized copy stand. At the digitization Lab, one of the Palm leaves was digitized, recto and verso. The collaboration between labs allows the Preservation Lab to obtain a great quality image of a Palm leaf to print a high quality surrogate.
i37044734_1197_dig01ni37044734_1197_dig02n
Once the Preservation Lab received an image with enough quality to work with, the process of creating a surrogate started.
In order to create a surrogate, it is important to have in mind several different aspects such as the purpose of the surrogate and the physical characteristics of the original object (texture, thickness and colors). When thinking about the purpose of the surrogate one has to answer questions such as: Is the surrogate going to be displayed or handled?  If so, how?  Behind a glass case? Will it need a presentation enclosure?
In this case, the purpose was for the librarian to be able to show a “real” palm leaf page without having to actually handle the original fragile leaves.  Also, having a surrogate of a palm leaf would allow patrons and scholars to handle a replica of an original object without having to unwrap and open the book.
Our goal was to create two surrogates; one in color, true to the original Palm leaf page; and _dsc1362another black and white, allowing the writing to be read easier.
Since we wanted to create a surrogate as identical as possible to the original, it was necessary to study the original object’s texture and thickness, as well as consider specific details such as gilt edges or punched holes.
The first step was to select several papers to test for printing.  Selected papers had a similar texture and thickness to the original Palm Leaf and/or were selected because they contained a handy ICC profile.
Once the papers were chosen for texture, thickness and color profiling, the image obtained from the Digitization Lab was enhanced in Adobe Photoshop CC 2015 and several surrogate samples were printed using a P7000 Epson Printer pigmented ink jet printer.

Middle holes were punched with a Japanese hole punch.
Middle holes were punched with a Japanese hole punch.

Surprisingly, papers containing ICC profiles did not necessarily produce a more accurate color representation.
Finally, after several trials and errors, a different paper was chosen for each surrogate. The colored surrogate was printed on an archival UltraSmooth Fine Art Epson paper.  The black and white surrogate was printed on an acid-free Curtis Brightwater Artesian white smooth paper.
Edges of the colored surrogate were pained with iridescent gold acrylic paint.
Edges of the colored surrogate were pained with iridescent gold acrylic paint.

Once the surrogates were printed and cut to the exact dimensions, the final finishing touches were made. On both surrogates, the middle holes were punctured in the same fashion as the original palm leaf.  For the colored surrogate, the edges were colored with an iridescent gold Golden High flow Acrylic.  Once the surrogates were complete, the process of constructing an enclosure for both the surrogates and the original object began.
 
 

Constructing a new enclosure

I’ve heard the joy should not be in the finished product but in the process. I have to say I agree with that theory. I love receiving a challenge like this and pounding out a solution. This particular enclosure had many facets which turned out to be exciting as well as rewarding to problem solve together with lab staff.
plam-leaf-3
Using a structure engineered by our lab conservator, first, I created a double-sided sink mat with two open windows to display both sides of the two surrogates.  Rare earth magnets were introduced as fasteners to hold the objects secure inside each mat. The surrogates are supported and viewable through a Vivak and polyester transparent L-sleeve, which is removable.   The Vivak and polyester sleeve was welded together on the lab’s Minter ultrasonic welder.
i37044734_1197_d05n_surrogate_packing_1
Volara supports were constructed to cradle the book so the gilding would not touch any abrasive surfaces, and so there would be a support for the cover once opened. The surrogates help provide information to patrons without causing wear and tear on the fragile book through handling. Originally, we considered storing the surrogates in a tray below or above the book to conserve shelf space, however by arranging the mats next to the object, they could immediately be on display when the enclosure is opened.  I am pleased with the outcome.  It is now possible to enjoy all the parts of this amazing work within the enclosure itself while minimizing the opportunity for damage, as well as providing a “wow!” factor.

Connections. Collaboration. Community. Oh My!

Connections. Collaboration. Community. Oh My!

Each year, the International Federation of Library Associations and Institutions (IFLA) holds an annual conference bringing together colleagues from over 120 countries to experience international librarianship.  Past conferences have been held in Istanbul, Singapore, Berlin, and Bangkok.  In August of 2016, IFLA hosted their annual conference in Columbus, Ohio titled, Connections.  Collaboration.  Community.
On August 19th, as part of the University of Cincinnati Libraries tour, the Preservation Lab was honored to welcome our international librarian colleagues for a visit to our lab where we discussed our role in collaborative preservation within Ohio – and locally as a conservation lab serving two institutions.
During our 40-minute tour, we highlighted treatments for special collections and discussed the importance of treatment documentation.  Ashleigh invited guests to see in-process treatments and demonstrated filling paper losses using leaf casting techniques on a suction platen.  Jessica walked visitors through the lab’s treatment documentation process in the conservation lab’s digital photography studio.  Teaming up on preservation were Holly and Hyacinth who showcased preventative storage enclosures and exhibition mounts.  They worked in conjunction with Veronica who carefully hot-stamped bookmarks to make keep-sake souvenirs for guests to take home from the lab.

Polyester Encapsulated Page Binding *Part One: The Structure

Polyester Encapsulated Page Binding *Part One: The Structure

The past two years have become an exploration into encapsulated page bindings!
Recently, I found myself faced with a fascinating scrapbook preservation project from the Public Library: the scrapbook of Althea Hurst.  I took the opportunity to further research encapsulated bindings made by other institutions to find an existing solution that would fit the needs of the Public Library’s scrapbook.
I didn’t know much about making an encapsulated binding before starting these projects, other than the bindings are usually time consuming and expensive due to the amount of welding and polyester film required.
Being a novice at the traditional encapsulated page binding, I started off with the following criteria in mind:

  • Something elegant to house an important object
  • Lightweight, protective, yet strong and supportive for large brittle books
  • Reversible for displaying pages, future repair, or digitizing parts

I figured, “This will be easy.  I’ll take a quick look to learn the structure of a traditional encapsulated binding and be on my way to preserve the attached parts.”
Little did I know, after reading a few articles and surveying a few structures – there isn’t a standard model.  There are many variations depending on how an object is used, as well as the condition of an object and format.  I was surprised to find that encapsulated bindings can be screw post bound or sewn in a variety of ways!
Here are a few case study examples:
Example #1: Larry Yerkes model, images from the University of Iowa Libraries’ website

UofM    UofIowa

http://digital.lib.uiowa.edu/cdm/compoundobject/collection/binding/id/55/rec/4

This is a full cloth covered binding that doesn’t reveal that it is an encapsulated page binding until you take a closer look inside.  I especially like that the pages are supported overall due the setback joint of the cover.  Also, the spine is covered, protecting the encapsulated pages from dust.
The drawback to this structure is it might take a little work to remove the case if the object needs to be disbound, thus requiring a new case for rebinding, resulting in an expense of time and resources.  However, I found it an overall elegant construction and took note of the protective paper endsheets.

The Lab’s first encapsulated binding project was to house a brittle oversized text from the University of Cincinnati’s Classics Library after it received in-depth treatment.  The first structure we experimented with was a modified full-leather-over-an-exposed-spine binding structure.  This structure was taught to the lab’s technicians, Veronica Sorcher and Chris Voynovich, at a course by Gabrielle Fox.  The sewn structure was altered from Gabrielle’s original form by using a cloth covering.  The textblock consisted of polyester leaves welded into folios with Hollytex hinges (a new technique I discovered last year – more on this in Part Two).  It was sewn with a single pamphlet stitch through each gathering, therefore, should a gathering need to be removed in the future, it could be cut out without disturbing the rest of the binding.  I found this solution extremely satisfying. The rounded spine structure complimented the second volume’s split board library binding well. It handled nicely and opened flat – perfect for a paleontology class to flip through while looking at a book of plates.

Example #3:  Binding by my predecessor, Kathy Lechuga, bound at the Preservation Lab in Cincinnati.

This is a traditional structure that is elegantly quarter bound with a cloth spine and marbled paper boards.   I like that this is a relatively quick structure to construct compared to the University of Iowa model.  This design is perfect for a thin group of lightweight paper as shown in the image above.  It’s a screw post binding which makes it reversible.  Since the spine is uncovered, it can easily expand if additional pages are added later.  This structure is reversible and adjustable without the need to construct a new binding.

In the above example, the screw posts are positioned on the inside of the cover.  There are no exposed screws on the outside of the book, so books adjacent to the binding on the shelf are not at risk to abrasion.  However, compared to the University of Iowa’s version, I noticed that the position of the posts places the cover’s joint at the edge of the spine, rather than set back.  This results in pages that are unsupported near the gutter when open.

In the above example, it’s not an issue for the pages to flex near the gutter.  I think this is a perfect structure for the needs of this specific object, however, I kept this in mind since flexing at the gutter might be problematic for an oversized heavy scrapbook with brittle pages that are crumbling.  To remedy this, the screw posts would need to be situated on the outside of the binding so the cover’s joint would be set back.  Unfortunately, some may argue screws on the outside of the binding aren’t quite as elegant.

After reading Henry Hebert’s extremely descriptive article in Archival Products News, I saw a beautiful example of screw posts on the outside of the binding and I really liked how the brittle pages were supported overall.  Was there a way to have the best of both worlds?

Example #4:  Ohio Book Store, Cincinnati, Ohio

Similar to Kathy’s version, this binding contains a few fancy additions: A reversible cloth spine and an extra flap to cover the screw posts on the inside.  This flap helps protect the screw posts from rubbing on the inside of the cover, as well as possibly preventing the screws from loosening overtime.

Example #5: University of Michigan Side Sewn Binding

One of the final versions I came across was the side sewn cased-in binding introduced to me by my talented Buffalo State classmate, Aisha Wahab.  I loved that the binding was sewn.  In a pinch if I was out of screw posts I needn’t worry.  But more importantly, this binding is elegant, the spine protected, and perfect for housing thinner books that don’t need the thickness of the aluminum post.  The only issue – not as easily reversible as other bindings since the sewing was covered by cloth.

Through my research, I didn’t find a quick fix with a one-size-fits-all structure to meet my needs.  Instead, I was able to incorporate some of my favorite elements from each structure and create my own.

The next hurdle to jump:
How do I encapsulate a scrapbook that houses a variety of adhered material, such as pamphlets, postcards, letters, maps, and more, and still make the parts accessible?!  See the  Polyester Encapsulated Page Bindings, Part Two.

Preservation Week Fun!

Preservation Week Fun!

One of the things I love most about working here in the Lab is that’s like the proverbial shark: always moving. We’re constantly learning and growing and trying new things; it’s great! We do, however, reside rather off the beaten path in the library, so it often happens that unless people have to come down for a specific purpose, they never know what we’re up to now.
Enter the annual Open House. You would think that after so many years, it would be pretty rank and file, but we’ve managed to keep the fun. This year, in addition to learning a few new things about the lab’s treatment reports on the UC Libraries’ Digital Collections & Repositories site and the hot stamper bookmarks that everyone has come to know and love, we focused on papermaking, highlighted by the opportunity to pull a piece of their very own.  Holly and Catarina walked our guests through the process, to great (and messy) results. People love the opportunity to mix it up and put their hands in things, and I would definitely call it a success.  On top of that, our conservator, Ashleigh, displayed an array of different types of paper and plant fibers that are used to make paper, and she demonstrated and discussed the different ways in which we use paper in the lab (mends, pulps fills, etc.). It was such a good time that I’m not sure how we’ll top it next year. No doubt there’ll be something fascinating going on. Stay tuned!
