Occurs when the ink is thin or the pad slips during printing. The slippage of the pad during printing may be caused by a hard pad, weak device, inclination in a part of the device, or excessive pad pressure. Causes and solutions:

Causes of Pad

• If the pad is too hard, a softer pad should be used.
• If the pressure exceeds the limits, the buffer pressure should be adjusted or a holding apparatus that provides better support should be prepared.
• If the print area of the pad is too small for the image, a wider pad should be used.

Causes of Printing Block

• If the printing block (cliche) is too deep, a new cliché should be prepared at the appropriate depth.
• If the type of cliché is wrong, a new cliché should be tried with the screen or a different type of screen should be used.

Reasons Caused by Ink

• If the ink is slow to dry, try a new mix with a fast-drying thinner.
• If the ink is thin, unthinner ink should be added to thicken it.

Reasons Based on Material

• If the material surface is extremely uneven, a specially shaped pad should be used or the pad position should be adjusted.

Other Causes

• If the holding apparatus is not suitable, a suitable apparatus should be prepared.
• If the working mechanism is not suitable, the mechanism should be prepared again.
