PVC card common quality problems and solutions

Edit:adminTime:2018-10-31 Click:464SmallMiddleBig

 

Since most PVC cards are imprinted in printing, dozens of singles are spelled on the same PS plate, so it is difficult to take care of each single in the printing and coloring, and sometimes it is a certain color. The other single color is far behind.


01. Color deviation.

Since most PVC cards are imprinted in printing, dozens of singles are spelled on the same PS plate, so it is difficult to take care of each in the printing and coloring.

A single, sometimes aligned with a single color, but the other single color is far from the deviation.

The solution to this problem is to use special edition printing, that is, how to print a single PS, so that you can follow the order, color

Will also be more accurate.

Sometimes the reason for the color cast is the large change in the color of the material, which causes the printed PVC card to be far from the usual, for example if the material

If the color is darker and the finish is not enough, the printed cards will all be dark and black. This problem can only be solved by replacing the material.



02. PVC card scratching is serious

The main reason for this quality problem is in the synthesis process. Since the PVC sheet is pressed with a steel plate during the card synthesis process, it is heated and pressurized.

Two PVC sheets are put together. If the steel plate finish is not good enough, or the steel plate is not well maintained, it will wear on the sheet when pressing the PVC sheet.

The surface leaves relatively obvious scratches, which affects the aesthetics of the card. The solution is to replace the steel plate that has worn out.



03. Card deformation

The reason for the deformation of the PVC card is that when the punching code is set, if the punching pressure is set too large, it is easy to deform the card. The solution is to press the press

The power is small.

Another case where deformation is prone to occur is that one side of the PVC card is coated with a synthetic film and the other side is not. Due to the different deformation coefficients of synthetic film and PVC, the card

There is a synthetic film on one side of the sheet, which can easily cause the card to bend. The solution is to add a synthetic film on both sides of the card, or both sides.
