How to control the quality of bronzing paper and water paste overprinting?



Why do the gold foil paper stick to the water paste printing? Do you know the customer friends? The following is explained by the technicians of the gold foil paper manufacturer, I hope to help you.

1. The combination of hot stamping paper and backing paper is not strong. There is no other way than to replace other brands of hot stamping materials.

2. The solid content of the binder present in the water slurry is too high, which can be solved by reducing the amount of the binder and slightly increasing the amount of the crosslinking agent.

3. The ratio of the binder present in the water slurry is unreasonable, that is, the polybutyl acrylate is higher than the poly(ethylene) (or methyl acrylate). This kind of ratio is softer, but the surface of the print will be slightly sticky, so that the temperature will make the adhesive more sticky when bronzing, and the gold foil should be stuck where there should be no gold foil. The dosage form is mixed with a harder binder for 1:1.

The above is all about why the hot stamping paper will stick to the water paste printing. If there is anything you can't understand, you can communicate with our customer service. We will serve you wholeheartedly.
