It is inevitable with Risograph printing for there to be miss-registration. This happens because like screen printing, Risograph prints one color at a time with each color requiring a new stencil. This increases the likelihood of miss-registration the more the image is ran through the printer.

Areas of full ink coverage are likely to cause variation in color and texture, as well as flooding and spotty coloring.

As Riso ink is a soy based material, it’s drying time is much slower than many other inks. At times this ink may never completly set into the paper. Even at its driest, the oils from your hands can cause the ink to smudge or leave behing marks when handling.

The paper is fed through the Risograph making contact with many tires and rollers to help it continue its track. When the print is heavily inked, these feed rollers will most likely leave marks when coming into contact with inked areas. Light tire marks can be erased.
