Has anyone else here tried Gumoil?

[Fulvio]

Thanks.
It's a digital negative (actually a positive on paper) printed on cheap office paper with a ink jet printer. I've tried transparency film but thus far all the gumoil prints from those transparencies have been duds. I know next to nothing about making digital prints so I'm kinda winging it while I learn.

ahaha... this might explain...
I want to try too with an inkjet paper positive... or perhaps a paper positive from the darkroom...

as for the gum... did you use powdered gum or the liquid ready made one?

thanks a lot, I want to try again now!

I use premixed liquid gum.

Also, for places to look for powdered gum, try art supply stores that offer printmaking supplies (like intaglio and lithography), eg: Daniel Smith, they should have it since gum arabic is needed for some of those processes too.

it's alright, I found and tried powdered gum, but I didn't see any difference...

I will try with the paper positive thing, who knows..

Hello all

I've posted one of my attempts at gumoil in the APUG experimental gallery,

haven´t seen it with sound yet, so i don´t know whether it could help you...

Interesting video. It's kinda strange - whenever I look at people demonstrating things, it always seems so easy. 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 :-)
