fallingkind asked: Hello there Tony, I am an Photo/art Grad student at Texas A&M Corpus Christi University, my name is Joshua Dancause. I am such a fan of your brilliant work with Gum bichromates. I have been researching your workflow and stumbled upon your Tumblr through youtube. I found that someone had asked you about your registrations marks and step tablets and how they were made etc. In your post you had mentioned if they emailed you, you would send them a tiff file, could you do the same for me? Best, Josh
Thank you. Send me an email email@example.com and I can email you the TIFF files.
oldsoulslove asked: I was looking through your archive for tips on Gum printing. I was wondering how you prevent against paper shrinkage with so many layers of gum and cyanotype. I did notice in one post that you said you do not used any backing. Also, do you size your paper and how so? Thanks in advance!
a-cheers-blog asked: Hi Tony, Thank you for your sharing your experiences with us, you have mastered this craft. I have a couple of question about monochrome printing. Can we use the RGB curve that you have introduced in other posts for black & white printing too?? or we need to make a new curve specifically for B&W? how many layers usually you end up with in B&W. And also what brand you suggest for black pigments? Thank you
Thank you for your comments about my work. Yes, you can use the RGB curve for B&W printing too–especially if you’re going to use multiple layers. I do not use a curve specifically for B&W printing. I have used the Winsor Newton “Lamp Black” for my black pigment. Hope this helps. Tony
safakoncu asked: Hello again, I apologize to ask again and again but what I wonder was is there a backing to your print (during process) and do you remove it when printing is done. Some people glue their paper to aluminum sheet, in your sample photographs I see some blue material at the back of print. I wondered what was it and how to remove when printing process is over. Thanks again for your patience. (sorry my native language is not English and I might not expressed what I ask in correct way previously).
No worries, I believe I understand your question now. I’m not sure what blue material you’re seeing in my sample photographs, but I do not glue my paper to an aluminum sheet or any support material. I use the Rives BFK sheet alone with the negatives when I print. Hope this helps. Tony
safakoncu asked: Hello again, I meant the paper you use is sticks to a blue medium like plastic sheet, how to stick our paper to that medium and how to remove when print is completed. I did cyanotypes and will try gum bichromate, everything ready just waiting for good weather to come (I do not have UV lightbox yet) Thanks again for answering and sharing your knowledge with us.
I use Rives BFK watercolor paper for my prints. I place my Pictorico negative on top of the coated paper and put inside a vacuum table underneath my exposure unit to make my exposures.
safakoncu asked: Hello, thanks for sharing all these valuable information with us. I just want to know how do you fix your paper on the blue film you use (looks like x-ray film to me) and how do you remove after print is done. Thanks again…
I make my negatives using Pictorico Ultra Premium OHP Transparency Film printed on an Epson 1400 printer. I use cyanotype for the first layer which develops in water; followed by an emulsion of gum arabic, pigment and ammonium dichromate for the subsequent layers. Hope this helps. Tony
