Lumi photoreactive ink will let you print with a negative on any absorbent, natural material.
It's a lot of fun to create your own design and have it printed without screen printing, with really easy clean up.
How did we get a Lumi kit at ADX? Well, first we registered as a makerspace, and when an e-mail said "Would you like to try Lumi?" we said Yes!
Step 1: Developing
I have done a little time in a photo darkroom, and Lumi is a really clean, easy way to do basically the same process, using the sun, being able to clean everything up with water, and no weird fumes.
I figured that a developing technique like dodging could be adapted to Lumi, so I tried it.
Dodging is where you use your hands to control where and how much light gets to a print, Block an area, and it's lighter, make a cup with your hands and expose just one area, and it'll be darker.
