Definitions for "Misregistration"
Slight gaps between overlapping colors and moire patterns in process colors. Trapping and overprinting are two techniques that help compensate for misregistration. Misregistration occurs when paper stretches and shifts as it absorbs moisture and is pulled through a press. The colored plates on a multi-color job misalign, resulting in two problems as ink gets laid onto the paper.
The mis-alignment of features, e.g. solder resist to pad misregistration.
Nonconformity of the position of a pattern (or a portion of the pattern), a hole, or other feature to its intended position on a printed board.
