Its characteristics are: micro-corrugated board selection unit quality control in the 380 ^ -440g/m2, the use of materials for 185g/ml recoated white cattle card +90g/m2 corrugated paper +140g/m2 white cattle card; moisture content control in 7 %^`9%; corrugated direction is perpendicular to the printing line pressure; ink emulsification rate is controlled between 15% to 18% during the printing process; the blanket selects the dot reduction rate) 95% of the blanket; the printing plate material selects the dot Really restored high fidelity TP plate. The present invention makes up for this gap in the history of offset printing in China. The effect of color reproduction of the printed product is good, the image is clear, the printing pattern has a rich sense of hierarchy, and the printing quality has reached an advanced level.
