    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..

    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 :-)
