thx for the tips.
all 3 tests are coated and dried in exactly the same circumstances. I put them in a self made drying cabinet that has been tested and has no light leaks. If I would use a dryer, the gelatine would melt, so that's not an option.
safe light is red like recommend by Mahn. Not even darkbrown.
I'm going to try the wetting agent in the emulsion for an more even coating and coat 2 times.
I have not tried to add the hardener to the developer yet. Will do that today. According to Mahn, you're not supposed to add it to the fixer, because of the long washing time, which would damage your emulsion. A
so I need developer early on in the process because otherwise the emulsion lifts during developing.
I tried misting the developer, but that doesn't give me an even coverage of the developer on the canvas.
I want to print on metal too, did you take any extra precautions like using a alkyd resin primer or just gelatine.
