How to Select the Suitable Rubber Pads?

Shapes & Sizes of the Pads

• Normally, we select the pads basing on the sizes of the printed pattern

• If there are many fine lines, we use sharper and harder pads

• Use bigger/softer/flater pads for bigger printed patterns

• If there is combination of the patterns, use combinative pads

• When pressing the pad to a certain level, the pressing angle is not good for exhaustion. Therefore, do not choose too small pads when basing on printed size

• When using harder pad, the pressing speed must exceed ink-floating speed. Otherwise, the underflow-ink might occur

• When the ink contains too many bubbles, a harder pad can sometimes discharge the air out of the ink

• When the printed area is curved, the deformation occurs when you press the pad too fast

Hardness of the Pads

• Some silcone are soft and suitable fpr soft pads. However, some silcone are only suitable for hard pads . If making it into soft pads, it will reduce the life of the pads.

• Normally, the sharper/harder the pads are, the better exhaustion they are. Therefore, we use sharper/harder pads for thinner lines and patterns.

• Hard pads are with better exhaustion but it is also easier to cause underflow-ink.

• For bigger area printing, use softer pads to avoid uneven shades.

• The harder the pads are, the greater that the pads can hold when printing.
