In this intensive two-day workshop, we will learn how to print in the 19th century photographic process of gum bichromate. Using color separation negatives, we’ll learn how to make multilayered, tri-color gum bichromate prints on watercolor paper.
After mixing an emulsion of watercolor pigment, potassium dichromate, and gum arabic, this mixture is brushed on watercolor paper, dried, and by placing a negative on top it is exposed to UV light.
We then ‘develop’ the prints in plain tap water. Layers are built by repeated coatings and careful registration of negatives until a full, rich image is achieved.
We will also explore one-coat, gum over cyanotype, made using black and white negatives.
No prior experience with this type of printing is necessary, so join us for two days of fun and experimentation with this interpretive, intuitive, and infinitely creative photographic printing process. Once you experience the joy of gum printing, you will never be the same!
The making of digital negatives will be shown, but for the workshop itself, please send four color image files (300 dpi at 10” on the long side), and one black and white image file if you would like, at least one week prior to the workshop.
Please complete the WORKSHOP SIGN UP FORM attached below before payment!
Please complete this workshop sign up form before payment! This helps us stay in contact with you as well as update you with any information you may need before the workshop.
Photogravure Learn the art of photopolymer gravure printing in this one-day workshop! Using light-sensitive steel-backed Solarplates, participants will create 4 x 5 gravure etching prints from their photographs. This environmentally friendly process translates photographic detail into ink on paper with unparalleled beauty.
No prior experience with printmaking is required. All necessary aspects of printmaking will be discussed including choosing inks, papers, and wiping material. Wiping and inking techniques will be covered. Be prepared to marvel at the way your photograph is transformed through ink on paper!
The making of digital positives will be discussed, but for the workshop itself, please send one color or black and white image file (300 dpi at 10” on the long side) to be made into a digital positive prior to the workshop. An email with details will be provided once you are registered.
All materials for this workshop are included in the registration fee.
Here is a brief outline of the process that will be presented in this workshop:
Starting with your digital photograph, a 4 x 5 transparency positive will be made
The positive is then laid on top of the light sensitive polymer plate and exposed to UV light
Washing the plate in water etches the image onto the plate
Once hardened, the plate is hand inked using water-soluble intaglio inks
The inked plate is then run through an etching press onto dampened paper
You take home 3 photogravure prints of your image
About Karen Hymer For the past five years Karen Hymer, an artist and educator based out of Silver City, New Mexico, has ventured into the world of printmaking – exploring imagery in the form of photopolymer gravures. Her current work explores the effects of time on the human body and various plant life. Hymer’s richly detailed photogravures emphasize the interplay of texture, pattern, light and shadow in muted earth tones. The decontextualized close-ups of the body and decaying plants reveal a poetic beauty in these often-over-looked subjects.

Get back in the studio and practice your skills! If you have taken a Photogravure workshop at Art Intersection or are proficient in the process, you are invited to participate in an Open Studio day dedicated to photopolymer gravure. Please note, this is not a workshop; while you are encouraged to share knowledge with your studio mates, there will be no formal instruction.
If you are not familiar with the photopolymer gravure process, learn it the day before in our workshop with Karen Hymer! Find out more and register here.
Materials Pricing
The $40 registration fee includes your access to our lab and equipment during the Open Studio. You are welcome to bring all your own materials and pay no additional fee. However, Art Intersection will have 4×5″ SolarPlates available for $8 each, paper and ink available for $5/print, and digital negatives for $5 each – this is a great option for those just starting out with photogravure, or those that don’t want to invest in their own materials yet. These additional items will be accounted for at the end of the day.
Working Group
In addition to the open lab, the day will start at 9am with a Photogravure Working Group meeting. This is an opportunity to meet other photogravure printers, reconnect with friends from workshops, and share some work you’ve done already. This meeting will last no longer than an hour, but may be briefer depending on the discussion. Art Intersection hosts Working Group meetings and Open Studios on a recurring basis.
Printing out Paper expert Siegfried Rempel will give a lecture on this fascinating process on Friday, March 24. Join us for this special opportunity to learn more about this historic method – the lecture is free and open to the public. If you’re feeling inspired, join us for our Printing out Paper Workshop the following day! Learn more and register here.
About PoP
Printing out Paper, or PoP, makes an image by exposing a negative and paper to light without any chemical development. With a printing-out process, you can watch your image come to life during your exposure, rather than having to wait until it is processed! Used originally as a simplified field process without the need of a darkroom, today we use this handmade emulsion to create artful images with subtle and warm tonality.
The use of Collodion in photography for the production of photographic prints an be found as early as the 1850s, and is most commonly used in the Wet Plate Collodion process to produce tintypes and ambrotypes. The concept of an “emulsion” of silver salts in a collodion binder was introduced by Gaudin in 1853 and by 1861 he was actively producing the “Photogene” collodion emulsion.
The collodio-chloride print has a similar physical appearance to its gelatin counterparts and it can be difficult to tell them apart. In fact, modern gelatin silver darkroom papers evolved from this early printing method! Today, we still practice the collodio-chloride process because of the rich and beautiful tonality it imparts on our images.
Late last month we had the pleasure of hosting a Platinum/Palladium workshop in our Photographic Arts Lab led by San Francisco-based artist Michael T. Puff! A master of this luminous, tonally-rich process, Michael led our eleven participants in making gorgeous prints of their own images.
Platinum/Palladium printing, a photographic process invented in the 19th century, has long been a favorite of alternative process photographers for its highly archival nature and infinite variations of gray tones as highlights shift to shadows. In the process Michael uses, ferric oxalate, palladium, and sodium chloroplatinate are mixed together, hand-brushed onto 100% cotton rag paper, exposed to UV light through a digital negative, and then processed with potassium oxalate and sodium thiosulfate. The end result is a handcrafted print that is estimated to retain its appearance for a thousand years!
Thank you to all of our wonderful participants, and of course to Michael for traveling to us to share his expertise!

Our first Tri-Color Gum Bichromate workshop with Diana Bloomfield last September was such a hit, we decided to do it all again! This past Saturday and Sunday Diana led nine students through this labor-intensive and difficult process. The workshop included many first-time gum printers, and despite the tricky nature of the process, all produced fantastic prints! As we gathered around to look at everyone’s completed work at the end of the two days, one thing was apparent: there is nothing like the magic of gum printing, and no one better to teach it than Diana Bloomfield!
We are grateful for all of our students, but we especially would like to extend a big THANK YOU to our four class participants who travelled from far, far away to take this workshop with us – Cary from Alaska, Timothy from Michigan, and Scott and Kelly from Pennsylvania. We’re so glad you could join us!
Diana discusses digital negatives during her demonstration at the beginning of the workshop
Diana “develops” an exposed print in water
Diana discusses the cyan-layer exposure she demonstrated as it hangs to dry – Terry, the student who provided the negative for this print, will later add yellow and magenta layers
Janet washes out her print after exposing the yellow layer
Karen coats her paper with a mixture of watercolor pigment suspended in potassium dichromate and gum arabic. The potassium dichromate hardens the gum arabic upon exposure to UV light; the parts of the coating blocked by the negative remain soft and wash away in water.
Tim washes out his print
Kelly very carefully registers the negative for her next layer
Janet, Tom, and Matthew attend to their prints
Each layer of pigment make a big impact when gum printing. The print on the left includes cyan, yellow, and magenta layers; the print on the right includes cyan and yellow. Both prints by Karen Hymer
Diana discusses the finished prints one by one with the class
Karen, Diana, and Tom mask off the brush-marked border of Cary King’s image in order to look at the print without visual distractions
Scott Wrage shares his tri-color print, not yet dry enough to pin up, with the rest of the class

This past Saturday, March 26 we had the pleasure of hosting a Photogravure workshop taught by Tucson artist Karen Hymer! The weekend began with a lecture by Karen on Friday night – she talked about the history of photogravure and the evolution of her artwork as she continues to use the process.
Seven students joined us for the workshop and got hands-on experience making photopolymer plates from their images, then pulling prints from the plates. Karen taught the process using Solarplates, which are steel plates coated with a light-sensitive polymer emulsion. When exposed, the polymer hardens; the unexposed polymer washes away in water, leaving an “etched” plate ready for inking after the plate has dried in the sun. Ink is then applied to the plate and wiped from the highlight areas. Finally, paper is laid on top of the plate and both are run through an etching press.
We are forever grateful to our friends at Cattletrack Arts Compound and Santo Press for lending us their etching press – we could not have done this workshop without their help!
Karen demonstrates the “development” of the Solarplate in water
Exposed and developed plates harden in the sun
