If pores are formed in the same area, it should be checked whether the tampon and cliché are damaged, and they should be replaced if necessary. Causes and solutions:

Causes of Pad

• If the bumper is too flat, a cone-type bumper should be used.
• If the pad surface is damaged, the pad should be replaced or the damaged area should be kept out of the print area.
• If the pad is too soft, a harder pad should be used.

Causes of Printing Block

• If an error has occurred due to bad acidification or pollution during the creation of the printing block (cliche), the cliche must be made again.

Reasons Caused by Ink

• If the ink is too thick, it should be tried by adding thinner.

Reasons Based on Material

• If the material surface is rough, a buffer suitable for the rough surface should be used.
• If the material surface is dirty, surface cleaning with alcohol should be applied before printing.

Other Causes

• If the ink is contaminated with silicone or oil, the ink must be renewed.
