[Printing Column 3] What is the technology for aligning printing registration?

About the technology for aligning printing registration.

General color printing is composed of four colors: black, cyan, magenta, and yellow, which together express all colors. The printing machine has a printing unit for each color, where the printing plates are mounted. The paper passes through each printing unit, applying ink in the order of black → cyan → magenta → yellow, resulting in the final printed material. What is important here is to properly align the four color plates. The reason for this precise alignment is not only to prevent misalignment of the image but also because it can exacerbate moiré patterns at the halftone level that make up the image. Printing operators need to have the skills to control misalignment caused by various factors. *For more detailed content of the column, please refer to the related links.
