I just published a 32-page standard-size, full-color zine, Rainbow Rolls: How to print with gradient inks!, authored by me (Amanda Wyatt Visconti). The free zine teaches you how to do gradient inking for letterpress on floor cylinder presses with inkable rollers (especially powered rollers).

For more info or to read, download, print the zine (all free!), visit zinebakery.com/homemade/rainbowrolls.
