Understanding the Pad Printing Pad

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. Two solutions to this problem are available.

The first is to use a pad with a hollow interior that provides the same surface hardness. This technique also reduces the cost of silicone rubber for such a large pad. The second option is a dual-hardness pad, where the core of the pad is made of a softer material and the outer layer is the harder rubber. Both methods can help, but the second produces a more stable pad. (A third option, of course, would be to use a different imaging process such as screen printing for larger image areas.)

We're aware of another very unusual pad configuration that is a bit reminiscent of the inflated pig bladder concept. This involves very specialized machines that use hollow pads that are inflated with air just prior to ink pick-up. The pad stays inflated until it comes into contact with the substrate, when the air is evacuated. The deflated pad can conform to a wider area of the substrate, allowing 1800 of a sphere to be printed (with standard pads, the largest angle that can generally be printed onto a cylinder or sphere is 1000.) One sample application is multicolour beach balls, where cartoon characters are printed directly onto the surface of the inflated ball. This technique is a cheaper alternative to in-mou Id labels for such specialized work.

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.

Quality Control of Pad Printing Pads

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?"
