If you have access to the August 2017 Issue of American Woodturner there is an article by my wife, Marla, on casting Japanese Chiyogami paper. It may help you some.
What I can tell you is not to cast tubes until you have tested the materials first. A piece of kitchen foil folded into a small container or a tart cup works. Glue a sample of the material to it and pour a little resin on top and see what happens. The test will show you whether the glue will let go, the ink will run or discolour, with the same applying to paint or nail polish backgrounds too. Once you know it is all good then have fun casting tubes.
Use the pressure pot when you cast. You don't need a lot of pressure,10 or 15psi/0.7 or 1bar is enough. It will stop very fine surface bubbles on the tubes that look like a shimmer, almost iridescence.
