A pad print plate, or pad printing cliché, is a flat metal or plastic plate that is used in the pad print decoration process.
Pad print decoration involves transferring an image from an etched plate to a product using a silicone pad. The pad printing plate is etched with the desired image or text, and ink is applied to this etched surface. When the silicone ink pad presses down on the plate, the ink is transferred to the pad, which stamps the image onto the product or component being decorated.
The pad printing plate is an important element in the pad printing process, as it determines the quality and accuracy of the printed image.
The quality of the plate depends on a number of factors, including the image’s resolution, the etching’s depth, and the type of material used for the plate.
Pad printing plates are made out of either plastic polymers or steel. The two different types of plates differ in etching techniques, life span, and precision.
Generally speaking, plastic pad print plates are more cost-effective than steel clichés. Depending on the type of plastic polymer used, the lifespan of these plates typically ranges somewhere between 15,000 and 100,000 impressions.
Steel Pad Printing Plates
Both thin and thick steel pad printing plates are highly durable options providing unmatched performance. Thin steel plates have a 1mm profile and can provide up to 150,000 impressions. Thick steel plates have a 10mm profile and can provide up to 1 million impressions. Both thin and thick steel plates provide crisp, clean lines and critical image alignment for high-tolerance applications. Thick steel plates provide the highest level of precision and repeatability available.
Trans Tech provides both blank as well as fully-etched pad printing plates. We also provide etching equipment.
Frequently, plastic plates are sold blank to be etched by our customers in-house, whereas steel plates are etched at Trans Tech prior to shipping.
Plastic pad print plates are typically etched with either an alcohol or water wash. Some plastic plates are compatible with CO2 laser engraving. Both thick and thin steel plates are laser etched.
Etching accuracy is a key element in ensuring highly repeatable, quality pad print decoration. When selecting a pad printing plate – it is key to find a partner with experience in areas such as finely detailed artwork and registration. Expertise in specialty-depth, critical-line, and multi-depth etching is also key.
To ensure highly accurate etching- look for a partner that can guarantee the accuracy of plate etch depth up to +/- 2 microns. Quality suppliers should also provide a multi-point quality inspection report with each etched plate.
We also offer custom-sized plates ranging from smaller 60 x 60 mm plates up to plates as large as 1000mm in length (for these larger plates the maximum exposure area is 900 mm by 610 mm.
Pad printing plates can be sent with Universal Configuration or punched holes that allow the plates to be used on Trans Tech or competitor pad print equipment.
