18th Century Poetry Pamphlets

By Lisa | July 31, 2017 | Comments 0 Comment

This past April, during one of the UCL Special Collections meetings, the Lab received a new stabilization/housing project; a collection of Latin poetry pamphlets translated into German from 1830-1917. This collection of 79 volumes is part of the Classics Library’s collection. While the Lab will be treating and housing all 79 volumes, the collection is being brought to the Lab in small, manageable batches. The first batch received by the Lab were pamphlets bd.66 to pamphlets bd.79.

After consulting with the Lab’s conservator, each pamphlet was evaluated and treated individually. The condition of each pamphlet greatly varied; some pamphlets were in good condition, with only small tears along the outer joints of the paper cover. Other pamphlets were in poor condition, with missing covers, detached covers, split textblocks, torn or missing covers.

After the first batch of pamphlets was evaluated and treated, four stabilization treatment types were established for future batches. According to the condition of the pamphlet, from good condition, fair condition, poor condition, to severe condition, each pamphlet received either no treatment, a minimal treatment, a minor treatment, a major treatment with stabilization though encapsulation, respectively. For future batches received by the Lab, the same treatments will be applied with small variations when needed.
No treatment: For any pamphlets in good condition do not require treatment, these pamphlets will simply be surface cleaned and receive a polyester film jacket.
Each image below shows an example of the treatments mentioned above. Click on the photo to view the full size image:
Fair condition/ minimal treatment: This group of pamphlets were in fair condition. There were minor tears on the cover that were mended.

Poor condition/minor treatment: This pamphlet was in poor condition. The cover was torn and detached and the textblock was broken with loose gatherings. The cover was mended and the textblock was repaired. The cover was reattached to the textblock.

Severe condition/ Major treatment – stabilization through encapsulation: This pamphlet was received in severe condition. The covers were detached from the textblock and showed major losses. The textblock was stapled and the staples had corroded overtime which stained the paper. The staples were removed and the textblock was sewn. The covers were encapsulated and sewn onto the textblock using Usu Mino tissue hinges.

Once the treatment of the first batch of pamphlets was concluded, the pamphlets were housed together in a custom made corrugated clamshell box with a clear spine. This model of a modified corrugated clamshell box will be used for the future batches of these pamphlets that the lab receives from the Classics Library.

At the moment, I am working on the second batch of pamphlets; pamphlet bd. 50-bd. 65. On this second batch most pamphlets are in poor condition. The covers are detached and some pamphlets have missing covers. However, the textblocks are in good condition. Below you will find a sneak peak of this ongoing treatment.

Fun with PhotoDoc – RTI (Edition 5)

By Lisa | April 28, 2017 | Comments 0 Comment

At the beginning of April I was lucky enough to attend a RTI (Reflectance Transformation Imaging) workshop offered by Cultural Heritage Imaging (CHI) at Yale University. CHI is a non-profit organization that shares and teaches RTI and Photogrammetry technology with cultural heritage institutions around the world. The class I attended was a 4-day NEH grant sponsored course taught by three RTI experts from CHI, and it was amazing!

This is a composite image of all the highlight points from one RTI section. The software uses these highlight points to map the surface shape and color of your object.

So, what is RTI? CHI describes it on their website as “a computational photographic method that captures a subject’s surface shape and color and enables the interactive re-lighting of the subject from any direction”. For highlight RTI, which is the least expensive and most accessible method for most institutions and what I was taught in the class, you basically take a series of 36 to 48 images of an object where everything is constant (settings and position of objects, camera and spheres) except for the light position. With a reflective black sphere (or 2) set up next to your object, you move you light source around the object at varying angles. Then, you take that set of images and plug them into the free RTI software provided by CHI and the algorithm detects the sphere(s) and the highlight points (from your light) captured on the sphere(s) and voila!…you have an fun and interactive way to look at your object’s surface texture.
Before I attended this fantastic training opportunity, our conservator and I knew right away what the subject of our first capture would be when I returned…a 16th century German Reformation text by Martin Luther with a highly decorated cover that is practically invisible under normal illumination.

Here’s a time lapse video of our first (and second) capture in the Lab…
That day (Tuesday) were were able to capture the upper and lower covers of the Reformation text (from ARB), the original silk cover from a 17th century Chinese manuscript (from Hebrew Union College) and an illuminated page from a German vellum prayer book (from PLCH). And here our some snapshots of our results from two of those captures (click on the thumbnails for a larger view of the image)…

This possibly 13th century German Prayer Book has a full stiff vellum binding and an illuminated first page. The varying modes highlight condition issues like worn/abraded parchment and flaking gold illumination, as well as the overall surface texture of the illumination.

I hope you’ve enjoyed getting a little sneak peek into RTI. I will be demoing and discussing in further depth this afternoon from 1:30 to 3pm at the Lab’s annual Preservation Week Open House. I also hope to do more RTI captures/processes in the future and share them here.

To our Provost and 29th President

By Lisa | January 31, 2017 | Comments 0 Comment

As a farewell gift and appreciation for all the work and time dedicated to the University of Cincinnati, The Preservation Lab was asked to create a custom binding for an Album for the Provost and 29^thPresident Beverly J. Davenport. UC Government Relations and University Communications provided the lab with single sheets printed with photographs of Dr. Beverly J. Davenport during her time at the University of Cincinnati.
To create the custom binding the single sheets had to be cut using one of our board shears. All the sheets were precisely cut to the same dimensions and a textblock was created.
Once the textblock was ready, endsheets and pastedowns were selected. In this case since this book was dedicated to our Provost and 29^th President, the color of the endsheets where the colors of UC, red and black. A white paper was chosen as a pastedown.
Since the pages were single sheets, the finished book would need to have a simple structure: a double fan adhesive binding. This structure is perfect for a textblock of single sheets as it provides a strong binding that allows the text block to be opened almost flat without causing the pages to separate from each other and break free. The adhesive is pasted onto the spine of the text block with a double fanning technique, where the pages are fanned in both directions allowing the adhesive to reach about 1 mm into the text block pages. After the pages are fanned in both directions, the spine of the text block received a lining of Cambric Cloth to provide support and an attachment for the cover. The spine was also lined with a handmade paper further strengthen the spine and prevent it from breaking from heavy use.
Once the textblock was finished, the cover was created, a cloth cover quarter binding. To continue with the theme of UC colors, a marbled paper with red and black tones was chosen. A black cloth was chosen for the spine lining. The album received striped red stuck- on endbands.

After the cover was made and the textblock was cased in and the album was ready to receive a title. The title was created using the Lab’s hot stamper. Several titles were made using the same black cloth used on the spine. A silver title stamped on a black cloth was chosen, since it best matched the theme and colors of the cover.

And the final result:

The Lab deeply appreciated this opportunity to contribute to the farewell gift and wish our 29^th President Dr. Beverly J. Davenport all the best.

Nineteenth Century Buddhist Religious Treatise

By Lisa | November 14, 2016 | Comments 0 Comment

In 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.

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.

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 another 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.

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.

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.

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.

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.

Preservation Week 2015!

By Lisa | May 28, 2015 | Comments 0 Comment

We love preservation. Of course we do. And as people who love preservation, we naturally love Preservation Week! Truly, we do. We love it so much that we take to the streets and invite people over to share it with us. We were so excited that we decided to start early this year, with live technical demonstrations in the mornings leading up to the big day. We wanted people to see what we were up to, ask lots of questions, and learn more about what we do.
We showed off the past year’s work, including some excellent pieces done by our pre-program volunteer, Catarina Figueirinhas. Everyone’s favorite, the hot stamper, made a return appearance. We topped off the festivities with a raffle for a book, handmade by one of our students, and of course, cookies (we don’t have open houses for the sweets, but they are a nice bonus!). We had such a great time with all of our friends and colleagues, and as always, we look forward to doing it again next year.
