Risograph inks are soy-based and do not conform exactly to any color standards. The listings below are approximates for reference only. Additionally, Riso inks are also slightly transparent and allow for variations in overprint and based on the color of paper they are printed on.

There are no Riso-supported Mac OS X drivers for the RP Series, yet it is possible to print directly to an RP machine from Mac OS X, without complex tinkering –if any at all– or extra files. All one needs to do is install Riso drivers from a different series that do have OS X support, then connect your RP to your Mac via Ethernet or USB and create/add your printer in the exact same way you'd add any supported printer under Mac OS X.

Here's a list of color codes for the RP series (should work on all models, have been tested on a RP3100UI and RP3700).
Unlike with newer machines which use chips to show the appropriate color on the Riso, the ink must be manually dialed in on the RPs through a Test Mode setting. It is however not necessary to change the color code on the drum after swapping ink colors but if you want the Riso to show the corresponding drum color on the display, you can use the codes to update the drum settings after changing inks.

A nozzle-to-nozzle ink transfer adapter is an easy and painless method of transfering inks from tube to tube. Transfering ink in this manner is a much cleaner process then filling tubes through the back and helps prevent air bubbles from forming during the transfer process.
