How to carry on the pad printing type pause right

Date:2021/6/26 13:48:00 Hits:6274

      Pad printing is a printing process principle is very simple, the pad printing head with silicone rubber moulds will steel on the photosensitive plastic gravure gravure or graphic transfer printing on substrates.Pad printing can be used for flat or all kinds of molding material printing, such as glass products, plastic products, metal products, watches and clocks, as well as electronic, optical products, etc.Its main characteristic is to irregular shaped concave and convex surface of the printing, it is difficult to can't even get to use other printing way, and USES the pad printing can be achieved easily, and can realize the exquisite multicolor printing.For the instruments, equipment, and a few small product is ideal for surface printing printing way.In addition, the stable printing, persistent, even if long time printing, printing precision won't change, and get rid of the drying procedure, can be continuous multi-color printing.Pad printing machine points mainly monochrome, double color from the color, four color, six and eight color color, etc.;From the degree of automation can be divided into manual, semiautomatic and fully automatic type, etc., and it is a moving printing machine with the CTP system, further improve the degree of automation.Here mainly from the overall structure of the pad printing machine and some local key parts for the current main moving printing machine on the market for analysis.
The main pad printing machine type
1. Manual type moving printing machine
       The pad printing machine structure is the simplest, some people think this kind of machine should disappear in the market, actually until now a lot of high-grade watches and clocks, and other equipment panel is done with this type of pad printing machine printing.Of course, this kind of machine generally will not appear in large-scale printing enterprise, in many small workshops are more.Its defect is very obvious, such as the production efficiency is low, once printing is very big, it is difficult to ensure the quality of all calendar consistency, but the operation is simple, small investment, so still very active in the market.
2. Open the ink tank pad printing machine
       Can move up and down or so of pad printing head, at the bottom of it there is a pad printing steel plate, ink tank ink was scraping ink device in the steel plate, pad printing head on contact with the steel plate and the ink.This design is simple, widely used in large print runs of pad printing machine.

3. Enclosed oil cup system
         This system is considered to be universal in the past the pad printing design, a Swiss watch company using the system has been 35 years.Ink to offer them in a closed oil, oil cup can move parallel to steel plate for your ink.When the oil cup directly above the steel plate, printing ink can flow to the graphic part of the sheet metal, and when the oil cup away, the scraping ring on the oil cup will not by part of the ink scrape.
4. Round transformation of pad printing machine
        The design of the structure from the gravure, more suitable for printing or continuous single substrates.This machine is mainly composed of pad printing plates, ink fountain and pad printing silicon roller, roller type steel plate was dipped into the ink tank, printing plate clockwise rotation, when the ink was blown down, scrape off;Counterclockwise, pad printing roller and steel roller pressure, the ink on the steel plate and move onto the pad printing roller;In the end, the pad printing roller contact with substrates, to transfer ink.
5. The hybrid moving printing machine
         This kind of machine was originally designed for ceramic printing, pad printing and screen printing form of hybrid.Its no use pad printing plate, printing ink by screen printing on the silicone resin coating, after the pad printing head contact with silicone resin layer, take away the ink, the final printing on substrates.The structure of screen printing and pad printing a lot of advantages, such as printing a lot of screen printing can not be finished surface (e.g., hyperboloid), and the selectivity was stronger than screen printing ink.
6. Satellite
          The moving printing machine is a kind of design in multicolor printing machine, rotary plane is controlled by the center of the CAM, per hour up to 750 RPM, if printing four-color per hour to 250 pieces, this machine is suitable for small and medium-sized printing.This machine mainly consists of two rotating platform and center control unit.A platform to place substrates, another platform plate.This machine is suitable for the main outside a single company, because they live a relative small print runs, and multicolor, choose the more profitable models.

7. Moving printing machine with the CTP system
          In the field of printing, CTP is not something new, now in offset printing and flexible printing has been widely used, even in the field of screen printing, also can see CTP expansion.But for pad printing field, CTP system in the application has only just begun.Used in gravure printing CTP system, to ensure that users receive digital image files, with laser mode to produce high quality gravure printing plate, without the need for film, exposure equipment and chemicals, etc.The ascension of automation, production efficiency, cost savings, and high fidelity image quality make gravure printing plate-making technology than other existing has obvious advantage.That investment, of course, many users first consider the problem.
