My colors won't stay in register - how do I fix misregistration on the flexo press?
Posted by the SuperPrinters team · 7/26/2026
Colors do not line up on the printed image, leaving blurred edges, white gaps, or fuzzy trap between separations. The misregister may be constant across the run or wander/drift as the press runs. Most often caused by incorrect plate mounting position or orientation (plate-to-plate alignment error at the mounter), among other possible causes — a full step-by-step diagnostic and fix follows below.
