Also, in case anyone's wondering how to do this in Krita:

1. Image > Convert image color space, select "CMYK"
2. Image > Separate image
3. Group all the split layers, and then move some of them a little bit to make the cool offset printing effect
4. Add a filter layer to the group, select "halftone" (under "artistic"), set mode to "independent channels", and then proceed to fuss with the options for like an hour

The post that originally sent me down this rabbithole was this absolutely sick piece by @curiah.city over on Bluesky: https://bsky.app/profile/curiah.city/post/3msvnvvxr6k2i

(It's not halftone, but I was like "wait how do I replicate this", and then stumbled into halftone printing while trying to do so)

A friend was like "the halftone effect looks like an early 2000's textbook" and I was feeling inspired, so...
