Introduction to Pad Printing
Pad printing, also known as tampography, is a printing process that has become increasingly important to industrial applications over the years. In the early 1970s, the process began sagging market shares over hot stamping and screen printing, particularly in printing areas where other methods showed no transactions or could not. This includes printing on irregular shapes and surface wells and assembling complicated substrates at a reasonable speed.
The unique aspect of pad printing lies in its ability to transfer a 2D image onto a 3D object. This is accomplished using an indirect offset (gravure) printing process that involves an image being transferred from the cliché via a silicone pad onto a substrate. The silquicklyad can quickly adapt to irregularly shaped surfaces, allowing pad printing on almost objectify. This versatility sets pad printing apart from conventional printing methods, such as silk screening, which is limited to flat or evenly rounded surfaces.
The Evolution of Pad Printing: From Origins to Modern Applications
The roots of pad printing can be traced back more than 200 years. Originally, pad printing was done by hand, with the first offset type of hand printing using a bag of soft gelatin material to transfer the image. Over time, the process has evolved significantly. For instance, printing plates were made from wood in the early days, and the photos were hand-printed. Nowadays, printing plates are made from various materials such as hardened steel and plastic, engraved photochemically or laser-engraved.
Decoding Pad Printing: A Basic Overview
Understanding how pad printing works involves understanding the components of the pad printer. Pad printers come in different designs, setups, and printing styles, but they all contain nearly the same components. The process involves an image being transferred from the printing plate (cliché) via a silicone pad onto a substrate (surface to be printed). The unique properties of the silicone pad enable it to pick the image up from a flat plane and transfer it to a variety of surfaces.
Comparing Pad Printing to Other Printing Techniques
Compared to other printing techniques, pad printing offers several unique advantages. For instance, it can efficiently transfer images on complex geometries, from printing on three-dimensional plastic parts to embossed or useless, or even golf balls. The process uses height compensators for ink cups to print at different levels in one printing run, offering versatility not commonly found in other printing methods.
Step-by-Step Guide to the Pad Printing Process
-
Ink Filling: The process begins with the ink cup sitting over the engraved artwork printing plate, covering the image, and filling it with ink. This is known as the home doctor’s.
