I've had a few goes at trying your gum image transfer technique and lost count how many times I've watched the video. Epic failures so far. I've used Charbonnel Black No. 55981 as well as Charbonnel Soft Black. I've also tried Setswell as well as Easy Wipe mixed with the inks, separate attempts. Applied with a Speedball 4 in roller too.
I've measured out everything with scales. Then tried different scales in case they weren't working. Yep, I've got lithography sponges in place too. 283 grams gum arabic to 113 grams water.
Applied 5+ rolls of ink to the plate too.
The best image I could get up was slightly more defined than a water mark. I'm running out of ideas as to what to do/combinations thereof to get a decent image. Any suggestions? Apart from try another technique?? lol.
Any insights would be greatly appreciated. I did learn to wear gloves when attempting though. No way I could keep as clean as they do in the video. Any feedback is greatly appreciated.
