Plate failure tips

With the increasing quality requirements for the printing department, the quality requirements for printing plates have also become higher and higher. We have accumulated some experience in dealing with printing plate failures for your reference.

Inspired by the "Lide" brand revision pen, we use large-sized watercolor pens or marker pens instead of revision pens for revisions. The results are also good and the cost is low.

Platemaking often encounters the problem that the PS text in the solar system may appear broken strokes or in the field. This not only affects the normal use of the PS plate, but also wastes the PS plate. In order to reduce waste, we use a 0.5mm fine-ballpoint pen. After the plate is repaired, the plate is heated locally with a hair dryer or lighter to make the ballpoint oil fully dry. Finally, the protective glue is rubbed. After the plate is repaired, the PS plate can be erased after the plate is repaired. Bake glue and bake it so that it will return to normal resistance.

In the printing process, our factory also encountered the normal printing plate on the machine just open, but after printing over a thousand sheets, the layout of the area there is a large area of ​​dirty or dirty with the problem. In this regard, we tried the ordinary Laundry Detergent to scrub the layout, resulting in normal printing plate. In addition, for the problem that the aging version did not ink, we also found a recipe for rubbing the plate with phosphoric acid and then scrubbing with clean water. The printing plate can be normally printed, and the entire printing process is not easy to carry dirty.
