The lower the accuracy of the paste plate, then the impact of the productivity of the printing machine is the greater. To solve the paste version of the accurate need to pay attention to the following aspects of improvement:

1, paste the plate accurate

① printing plate base must be square.

② The base of the plate and the plate must be flush.

③ The center line of the printing plate must be straight, and should be up and down.

④ Draw the box shape of carton on the base of the sheet, so that the paste plate is more accurate.

⑤ Keep the cross mark on the printing plate as the basis for measuring parallelism and data.

These 5 aspects are very important details, such as the printing plate base and the plate strip is not parallel, then in the pasting of the plate when the measurement distance will be deviated resulting in paste inaccurate. These 5 points can be done to enhance the accuracy of the paste.

2, the printing plate paste flat

If the printing plate is not flat, then there will be printing paste, dot blocking and other phenomena. The main reason for the printing plate is not flat is in the paste double-sided adhesive tape, tape and version of the fit when the bubble, resulting in bubbles where the layout will be raised, higher than the other places of the printing plate.

Then the strength of printing is not the same, causing printing quality problems. So paste the plate must pay attention to the flatness of the double-sided tape, which is a very important matter.

3, printing warped plate

If the printing plate and printing roller surface contact is not tight, will make the printing plate upward warping. And the warped part is very easy to penetrate the ink after the pop-up, resulting in the pop-up plate in the printing process was broken or lost.

This is one of the main reasons for the warped plate, so the use of adhesive tape must be better adhesion, but also a certain temperature resistance, in the first printing is completed after the printing plate for sealing, or the use of water-free adhesive paper sealing and sticking firmly.

Pasting the printing plate is a delicate job and has certain skills. If the printing plate is not good, then the efficiency and quality of the printing machine can not be guaranteed, in many companies have chosen to use the chief printer as the personnel to paste the plate, which also shows the importance of this position.
