The printing plate is not inked and the solution

Cause: During the printing process, the printing and printing department of the printing plate repeatedly wears and tears the Paper powder and paper hair that have fallen off from the water roller, the ink roller, the rubber roller, and the paper, and the photosensitive layer is gradually worn out and destroyed. Decreased, increased hydrophilicity. When the amount of fountain solution supplied to the printing plate is excessive, the fountain solution adheres to the graphics department and forms a water film, which results in inability to set ink.

Treatment method: printing plate is not difficult to remove without ink, due to the nature of the ink, the distribution of the printing pressure, the protection of the coating and the application of the protective coating at the time of stopping the printing, and other factors may cause this failure. The glue is thin and uniform, and the temperature is suitable for drying. The method of baking the plate enhances the wear resistance of the photosensitive layer, and this failure can be avoided to some extent.
