摘要
A method of printing multi-color images on pressure sensitive labels carried on a web uses a disk shaped mark for each color which is printed to form the image. The disks (spots) are printed on the image, or elsewhere on the top layer of the web, with one disk being printed on top of the other, so that the marks coincide in size, shape and position. If a color is misregistered, it appears as a crescent which extends beyond the multi-colored disk. Such misregistration may be immediately viewed on a video magnifier, using at least 400 magnification, and the misregistration corrected.
