Understanding the Pad Printing Pad

Quality Control of Pad Printing Pads

Poor-quality consurnables like pads can destroy the performance of the printing machine. When you receive pads from your supplier, it's vitally before accepting them.

Check the pads for:

  • blemishes on the print surface
  • foreign particles in the print surface, such as wood splinters "nipples" on the print surface.
  • firm attachment of the pad to the backing plate (The pad should be secure, with no air bubbles that will cause the rubber to come away from the base.)
  • hardness within +20 Shore (using your durometer gauge)
  • positioning on the backing plate (It should be concentric, with its vertical center line at a 900 angle to the backing.)
  • height (This is particularly important in multiple-pad applications). Report any defects to your pad supplier immediately so that replacement pads can be furnished.

Shape and Size of The Pad Printing Pad.

Shape is the most important variable in selecting a pad.

Hardness of the Pad Printing Pad

The hardness of the pad is normally determined by the amount of silicon oil used when the pad is moulded.

Surface Finish of the Pad Printing Pad

Throughout the pad-printing industry, the custom practice among pad manufacturers is to furnish pads with a high gloss finish.

Material of the Pad Printing Pad

This topic refers not only to the material of the pad itself, but also the base onto which the pad is mounted.

Special Printing Pads for Large Images

In some situations, a large image area must be printed and the machine does not have the power to compress such a heavy pad in a smooth motion.

Poor-quality consurnables like pads can destroy the performance of the printing machine.

Pad Printing Pad Life

Next to "What should I use?", the most difficult question to answer is "How long should a pad last?"
