A. Ensure accurate plate clamping
When clamping the printing plate, make sure that the plate is aligned with the cylinder or clamp of the printing press, and use a special alignment tool to do so.
B. Calibrate the printing press
Regularly check and calibrate the various components of the printing press to ensure accurate alignment between the cylinder, plate and blanket.
C. Controlling Paper Quality
Use high-quality paper to avoid paper deformation in the printing process. For easy deformation of the paper, you can print before the appropriate pretreatment, such as appropriate humidification or drying.
D. Adjustment of ink and printing parameters
Reasonable control of the viscosity, fluidity and drying speed of the ink to reduce changes in the location of the color area.
E. Optimize the paper transfer system
Ensure that the paper transfer system is clean and free of foreign matter to reduce the displacement of paper in the transfer process.
F. Regular maintenance of equipment
Regularly inspect and maintain the printing machine, replace worn parts in time, and tighten loose adjustment screws.
G. Check software settings
In the pre-press processing session, carefully check the settings of the typesetting software to ensure that the output parameters are correct.
