Multifunctional color mark set for detecting printing registration deviation

Abstract

The invention discloses a multifunctional color mark set for detecting printing registration deviation, belongs to the technical field of printing machine automatic control, and provides a multifunctional color mark set for the problem that registration detection cannot be conducted after a current photoelectricity type color mark is replaced with an image type automatic registration system. For aprinting factory with the image type color mark automatic registration control system, only a first color printing plate in one original set of photoelectricity type color mark printing plates is changed into the multifunctional color mark set, original color marks of the rest of printing plates are kept unchangeable, replacement of the whole set of printing printing plates is not needed, the printing plate replacement expense is saved, popularization of the image type color mark automatic registration control system is facilitated, and technology upgrading and updating are promoted.

Benefits of technology

This patented innovation allows for better measurement capabilities on both photography equipment used during production processes such as lithography or offset presses without requiring expensive sensors like cameras. It also extends its use beyond just detecting colors alone.

Problems solved by technology

This patents discusses how printers automatically register printings by measuring their location relative to reference points like colored areas called borders. These border lines provide important data about where the patterns should appear when they start being copied onto paper. To accurately measure these errors, images from both sides of the sheet may be taken separately without interfering with any other parts around them. Additionally, if one side needs more than just one copy of another kind, then some systems require specific markers attached to certain positions along its edges instead of all else.
