Interesting video. It's kinda strange - whenever I look at people demonstrating things, it always seems so easy. :smile: I have never seen anyone doing any sort of gumoil print, so I was a bit surprised by the seemingly heavy rubbing that was done.

I have been doing gumoils for about 3-4 months and am getting fairly nice results. I am unable to get a satisfactory second layer of oil, but I am happy with the effects with just using Van Dyke Brown or Lamp Black for my first layer followed by a 15 sec bleach. You can see my gumoils here:Guest Pass link

I have found out that a normal gum / bichromate ratio of 3:1 isn't thick enough for me. I have the commercially availlable liquid solution, but also made a 50% GUM SOLUTION (so 150 gram powdered gum, into 300 ml water). I now use a ratio of 2:1:1,5, meaning i use 2 parts thick gum, 1 part 'normal' gum, and 1,5 part dichromate, this is to compensate for the thicker gum, so it will get a bit more sensitive..

I still have the same problems as you guys, no details in the midtones, no real possibility for etching... but also looking further for answers :smile:

Resurrecting an old thread, did any of you have success? Are you still making gumoils? There is a woman doing some beautiful gumoils on facebook.

Everyone says to bleach the print after soaking it in water, but apparently, she doesn't bleach....

This process is not easy...

I would say it is more to the impossible side...

I've made a lot of tests. No image at all. The gum/dichomate produces a visible but faint image on 300g canson paper. After I spread the paint, nothing in this world will make it leave the paper. I've rubbed until the paper desintegrated, I placed in bleach, I even set the paper on fire ( I wasn't expecting this to work, I was just really annoyed by this process); I just get a black square.:mad:

My problem was that I could never get the ink to stick except for one time. But, I will give it another go because I HATE LOSING!

I'm happy I am not alone in this. NOW IT'S PERSONAL! I'm gonna oil the @&#$! out of that gum. Or vice versa... Not sure yet. Anyway, hope it works. :pouty:

No... I give up.
Until someone with good results post some insights, I'm assuming there are some parts of this process not being shared.

I have the book and I strongly believe that the book doesn't have enough information!

I've no idea - I have never tried to contact Karena for example, so I have no idea if she has any insights on the finer details.

Yes, I agree that the book is lacking - and the man behind it all passed away a few years ago.

Back at gumoil printing and getting much better results. Changes that I made to my works flow: more contrasty negative; applying sensitized gum with foam roller. Smooth, wonderful coating; longer exposure; matrix soaked in 24C water rather than 20C. I'll post a print once it has dried. It's not great but huge improvement.

Andrew, would love to see a print.
Do you size the paper before sensitising, do you bleach (what quantity/dilution/seconds) and how many oil applications needed to get the image as you want?

I'm using Fabriano Aristico, so sizing not necessary. I would like to try Rising Stonehenge, as I have a whack of it. Not bleaching prints. Just stick in a tray of cool water and wipe gently with wetted sponge. One application of oil paint. It's no where near what I want yet, but this is a huge improvement, and I'm getting better consistency.

Andrew, I like the image & it looks like you are getting quite a bit of tonal range.
Would this be down to the warmer 1st wash at 24deg.?
I guess the red patch is just in the photographic reproduction here as you only used 1 colour?
Thanks again for showing

That's really good. You say you don't use bleach? How long after spreading the oil paint do you place it in water? Could you post a picture after the exposure (before inking)?

Ced, only used one colour. Lamp black. Big improvements with warmer development bath, contrastier negative, longer exposure. Still very contrasty result. I think that is inherit in the process.

Glpoza, as soon as oil paint wiped off I stick print in water just for a few seconds, then wipe with sponge. The I'll post a pick next week as I'm away photographing.

Andrew, Thanks, I'm sure others along with me would love to see any other images you make in this process.
We should open a thread on the site where images that failed (any process) and could be used to help others trying different techniques where they run into countless problems. KR!
