After the completion of the batch of some samples of paper cartons for future production for reference. Each ink is best to run out of time, because leaving the next use may appear color.
(2), Ink volume is stable. The speed of the press running needs to be kept steady for a while soon for a while, in order to ensure that the press has a stable ink transfer state. Specific operations, the printing speed of the amount of ink is too large, large viscosity is also large ink.
(3), Plate pressure. The pressure of the plate and the role of the reaction of the impression cylinder, the printing operation will appear color light, color cast these, will feel that ink is not enough, and then increase the printing plate cylinder pressure, had to meet the requirements of ink, The result has a serious edge effect.
(4), the quality of corrugated cardboard is good or bad. Need to ensure that the corrugated board paper weight is stable, the same thickness, moisture content uniform, to ensure that the ink can be well absorbed. Want to print good quality need high quality cardboard.
