For stencil based printing with multiple ink color layers, color separation helps bring the original artwork into the layers (usually greyscale) used to make each stencil. This can be done by hand, analog or digitally. There are also a number of apps, websites, and other tools that help with color separation, especially for artwork that is already made, such as a photograph or painting. ==Apps== * [[Spectrolite]], a free Mac desktop app * [[Stochaster Apps]], a suite of apps for processing images that includes [https://www.stochaster-apps.com/coloraster.html Coloraster] for separation. * [https://apps.apple.com/us/app/graintouch/id6740813845 Graintouch] for iPad somewhat aimed at making faux-riso look digitally, but offers some color separation features. ==Websites== * https://www.risoseparator.tools/ * [[Risotto]] has an online print simulator * P5 Js riso https://antiboredom.github.io/p5.riso/ * Virtual overprint charts https://charts.issue.press/ ==ICC Profiles== Usually implemented with Adobe suite products. * [[Color/shift]] https://colorshift.theretherenow.com/profiles * https://en.exploriso.info/exploriso-colour-profiles/ * [[Risolve]] offers [https://risolvestudio.com/collections/riso-color-profiles color profiles] and an accompanying [https://www.youtube.com/watch?v=SCG4cf0HP_8 tutorial video] * ColorLibrary.ch has [https://colorlibrary.ch/ profiles for purchase] as well as a [https://colorlibrary.ch/how-to-install/ tutorial on using ICC profiles] and color spaces ==Color Separation related guides and tutorials on the web== * '''Exploriso''' has a [https://en.exploriso.info/exploriso/colour/ huge in depth guide to risograph color], including detailed guides on many methods for creating separations * [[Colorama]] has a [https://colorama.space/risoprinting-services/ guide with a color separation section] * Risotto offers [https://risottostudio.com/pages/tools tools] and a set of [https://risottostudio.com/pages/how-to-guides how-to guides] * Natalie Andrewson's [https://www.patreon.com/NatalieAndrewson patreon] has many tutorials for her method of color separation ==Books and Zines== * ''[https://www.natalieandrewson.com/products/dreaming-in-color-art-book Dreaming in Color]'' by Natalie Andrewson, PEOW2 * ''[https://spectorbooks.com/book/exploriso Exploriso: Low Tech Fine Art] by Sven Tilkak'' * ''[https://coloramabooks.space/products/layers4players Layers4Players]'' by by Chloé Barbier, Colorama.
