From Pad Print Machinery of Vermont
Probably the most difficult question to answer about the pad printing process is, "How do I determine what pad to use?" One answer won't apply for every shop or application. Rather than lay down inflexible rules, this article will provide a methodology for determining the optimum pad characteristics and a framework you can work within to get the best performance from your pads time after time.
As prior articles in "Screen Printing" magazine ("Pad Printing: Controlling Ambient Conditions for Better Quality," July '94, page 94 and "Cliché Selection in Pad Printing" Nov. '94, page 122) have stressed the key to good pad printing is to reduce and control the variables. Though the function of the pad seems simple - to just transfer the image from the printing plate onto the substrate - it is subject to the same types of print-quality fluctuations if you don't choose the correct pad type and use it properly.
