Lithography print with p5.js

hi community,
I’ve been working on lithography which is an analog printing method in my case with outlines generated in p5.js (not to be confused with risograph - which is a digital process and I also did with Processing in the past). Besides the process of generating the outlines, transfer to the aluminum plate and rest of the printing process is completely analog, done by hand.

While the process is analog, there are masking and contrasts that are analogy to digital process, which I find interesting.

In the code on openprocessing you can see the overlay of the original outlines on the (work-in-progress) resulting print.
