Introduction to keyboard printing method

Pad printing is a fairly old type of keycap printing method that has been deprecated and is no longer used because it is less practical and less efficient.

The pad printing method uses a set of letter typefaces as the original typeface. After the ink is applied to the ink by the robot, a set of soft rubber blocks is pressed onto it, so that when the rubber block is lifted, the writing ink is transferred to On the rubber block, then move the rubber block to the blank keyboard, press the rubber block, and the ink is printed on the keyboard.

Books, newspapers and magazines were printed in this way before the emergence of photosetting technology. Compared to laser etching and screen printing, the pad printing method does not have any printing conditions and can be used to print any form of keyboard. However, the shortcomings of the pad printing method are also obvious. Its printing speed is extremely slow, and the time for printing a keyboard can almost let more than 10 laser-etched keyboards go down the assembly line. Therefore, in addition to those small manufacturers that can’t afford laser etching machines, there is no way to use this printing method without any technical requirements. Keyboard manufacturers generally only use it to print high-end products that do not cost. Secondly, due to the influence of the printing process, it is much more difficult to perform film coating on the keyboard of the pad printing method than the screen printing. Therefore, many keyboards printed by the pad printing method are not coated, but by studying the composition of the ink. Improve the firmness of printing to enhance the life of the keyboard.
