Gum Printing

[ced]

Hello All Gummers!
I am not having great success with this process and wonder if anyone has tried this image and if so could please display the result that I may be able to figure where my problem lies.

I will print the separate layers on OHP films on Epson Photo Stylus 1440.
Excuse if this has been raised before and please direct me to the post, Thanks!

I assume you are printing separate RCB negs? is that correct?

Did you label the separate negs correctly so that you selected the correct pigment for them?

Can you be more specific regarding the problems your having. Color balance issues, pigment faking , staining , what???

How about posting images of your prints that display the problem.

What are your workflow steps and what is your chemistry that your using?

Bruce thanks!
The problem I have seems that the image does not develop up in strength and the result is a weak density and I can't figure if this is due to exposure or pigment or even the paper surface not treated properly(sizing).
I have 3 negs but just now I try just one to see where I need to be.
I have done some cyanotypes no problem but for gum it is so far off the mark.

Are you trying to print a tri color or one color image?

What do you men by "does not develop up in strength"? is it each print layer (Blue, Yellow, Magenta for tri color) or the final overall print result after all 3 layers printed or are you talking about your negative density?

What is your pigment ratio to gum? In one workshop I took they liked to use a very pale palette. I wanted stronger color results so I have now changed to more pigment in my pigment to gum ratio.

I am sure you know every gum person uses very different methods in achieving their desired print results.


if you could post some of your print results that would help to understand your problem.

Also- I recommend you get Christina Anderson's book "Gum Printing and Other Amazing Contact Printing Processes". Its a good resource and explains her technique for making gum prints.

Other Gum printers on this web site, that are far more experienced that me, can add their thoughts to your issues.

Good luck!

Bruce at present I am concentrating on just 1 layer to test the exposure/development.
My Pigment to gum is 1:1
In the winter months I will return to the tests and try to find the book you advise before then, thanks.
