一种胶印印前排版制版校准方法
By performing coordinate processing and comparison of the image information of the film and positioning paper before offset printing, correction data is generated. The position and angle of the positioning paper are adjusted using a stepper motor and a lead screw, which solves the printing quality and efficiency problems caused by unsuitable temperature or tension of the positioning paper during offset printing, and achieves accurate calibration and stable printing results.

AI Technical Summary
During offset printing, the physical deformation caused by unsuitable temperature or tension of the positioning paper can lead to a mismatch between the pattern being printed and the positioning coordinates, affecting printing quality and efficiency. Existing technologies make it difficult to accurately detect and calibrate the deviation of the positioning paper before printing.
By acquiring image information from the printing film and the positioning paper, performing coordinate processing and comparison, generating correction data, calibrating the original film, and using a stepper motor and lead screw to adjust the position and angle of the positioning paper, the registration accuracy is ensured.
It enables precise calibration of the positioning paper before printing, reduces offset printing plate-making errors, improves printing quality and efficiency, and ensures the stability of printing results.
