Four ways of printing and processing computer keyboards

With the development of informatization, computers have already been used in thousands of homes, the development and innovation of technology, the update of computers are also very fast, and the development of e-commerce has made our relationship with computers and their peripheral products closely related. The first thing to do is to bear the brunt of the keyboard. It has the most contact with us. The keyboard structure has experienced the development of mechanical, plastic film, and conductive rubber. Similarly, keyboard screen printing methods are becoming more and more diversified. The following editor will tell you about keyboard screen printing. Four tips.

1. Pad printing

Pad printing is a very old method of keycap screen printing. Because of its impracticality and low efficiency, it is no longer used. The pad printing method is to use a set of letter type as the original typeface. After the ink is painted on it by an automatic machine, a set of soft rubber blocks are pressed on it, so that when the rubber block is lifted, the ink will be transferred to the handwriting. On the rubber block, and then move the rubber block to the blank keyboard, press the rubber block, the ink is printed on the keyboard.

2. Immersion silk screen (also called sublimation method)

Impregnated screen printing is a screen printing method that is completely different from ordinary ink screen printing. It uses solid resin inks instead of common liquid pigment inks. This kind of ink will sublime into a gaseous state at high temperature, infiltrate the surface of the permeable screen printing product in the form of gaseous molecules, and then sublime, thus becoming a whole with the screen printing surface on the physical level, instead of just being "sticky" like ordinary pigment inks. "On the silk screen surface, so its silk screen is extremely strong. Moreover, resin inks are inherently superior in gloss and shape.

3. Laser etching

The so-called laser etching is the use of laser engraving technology to burn black grooves on the keycaps. Because the traces carved by it are linear, the arrows on the common laser etched keyboards are all hollow. Nowadays, many white keyboards on the market basically use this keycap technology. The main reason is that the manufacturers value its low cost. Although its production line is expensive, its daily output is more than ten times that of other screen printing methods. It is a burnt handwriting, so you can have a very clear and firm handwriting without any other measures. Another reason for its large scale is that it is more environmentally friendly and will not produce harmful products.

4. Silk screen printing (a common method in ink screen printing)

The principle is to cover a blank keyboard with a special silk screen, where the handwriting is hollowed out, and then the ink is scraped from above, so that the handwriting will be printed on the hollowed-out part. The characteristic of screen printing is that after the screen printing is finished, a layer of plastic can be brushed with a special screen. After drying, a plastic protective film covering the screen printing will be formed, which can prevent the handwriting from being used for a long time. Wear and tear, which is commonly referred to as keyboard overlay technology
