Shop life: a true rainbow roll! Typically, a press inked to print a background with more than one color is called a split-fountain or rainbow roll.
For this print run, Michaela used a shortened worm gear (created by designer-printer Cory) to squeeze in six colors of the rainbow. When the press is on and in use, the big top roller oscillates (or moves back and forth) to maintain an even layer of ink across all the rollers.
This limited oscillation makes it possible to print multiple colors at once, rather than losing colors that would otherwise blend. Essentially, shortened worm gear means your reds and yellows stay red and yellow instead of blending into orange.
We spend a lot of time thinking about ink, mixing ink, and working with ink, and we do enjoy using all the colors whenever we want, and sometimes all at once!
