The adhesion of ink cannot meet the requirements, which is a common problem in the transfer printing process. It may be caused by a lack of understanding of ink formula or incorrect selection of ink type.

In response to this issue, Yongzhuo Technology's silicone pad printing adhesive provides a solution to ensure good adhesion between the ink and the printing material.

The solution to the problem of ink adhesion not meeting the requirements is as follows:

1. Transfer head: Excessive silicone rubber on the surface of the silicone transfer head may affect the adhesion of the ink. Before using the new pad printing head, it can be cleaned with an alcohol solvent to reduce silicone rubber residue.

2. Corrosive gravure: If the corrosion degree of the gravure is too deep, it may affect the adhesion of the ink. It is possible to remake gravure plates with moderate depth to provide better printing results.

Ink: Choosing the correct ink type is very important. Select the appropriate type of ink based on the characteristics of the printing material. If using double ink, it is recommended to choose a harder transfer printing head for printing. In addition, ensure that the ratio of ink and hardener is correct, weigh the amount of ink and hardener proportionally, and remix the ink.

3. Printing material: Ensure that the surface of the printing material is clean. Before printing, clean the surface of the printing material with an alcohol solvent to remove dirt and grease.

In addition, attention should also be paid to the following aspects:

Pre processing work: Ensure that the pre processing work is sufficient and carried out correctly, laying a solid foundation for subsequent printing work. If necessary, the preprocessing work can be repeated.

Fixation time: The ink needs to be fully dried and fixed to ensure good adhesion. Before conducting adhesion testing, ensure that the printed material is thoroughly dried.

Post treatment work: If necessary, use a hot pipeline or flame drying device for post treatment to further improve the fixation and adhesion of the ink.

By choosing Yongzhuo Technology's silicone transfer printing adhesive, you will obtain a reliable solution to solve the problem of ink adhesion. Our products provide high-quality adhesion performance, ensuring strong adhesion between ink and substrate materials
