Flat Screen Printer is a printing machine with a relatively high frequency of use at present, which is generally applicable to industries such as plastics, toys, and glass. Generally speaking, Flat Screen Printer adopts gravure head printing technology, which is a good way to print and decorate the surface of objects, beautify the objects and indirectly increase the sales volume of the products. How does the Flat Screen Printer work?
The first step is to spray ink on the etching plate, and then use a retractable scraper to scrape off the excess ink. The ink remaining in the etched area will volatilize and form a gel-like surface, so that the glue head will drop onto the etching plate and absorb the ink smoothly. This is the first step of the operation, the absorption of ink will directly affect the quality of printing. Because there is too much ink, the pattern of the printed matter will become very thick; if the ink is too little, the pattern of the printed matter will become very light.
Then the glue head will rise after absorbing most of the ink on the etching plate. At this time, the remaining wet ink surface energy is conducive to the close combination of the printed object and the rubber head. The glue head will produce a rolling action on the surface of the object, thereby expelling more air than the etching plate and the ink surface.
In the whole process of production, the cooperation of the ink and the rubber head is important. Generally, a good cooperation is that all the ink on the etching plate is transferred to the printed object. However, in actual operation, the glue head is easily affected by factors such as air, temperature, static electricity, etc., so that it will not reach a good state. At the same time, in the process of transferring, it is necessary to grasp the volatilization speed and dissolution speed, and make it reach a balanced state in order to obtain successful printing.
Only by mastering a good Hot Air Stenter printing operation process, can the produced printed matter become beautiful and make it easier for consumers to love.
