The Riso Color Sciences Multipack is a set of color charts I use for my personal printing and a guide to how and why I print using halftone dots and markers.
The guide is written for Photoshop - but I explain the principles you can use in other software, such as how (and WHY) to set up screentone patterns manually.
----------
Four "faux-CMYK" screentone test cards, one Copic marker print chart, two sample prints, and a booklet with instructions/explanations of how I made them and why I approach color-mixing this way.
