how to buy a good Pad printing machine.

Pad printing is a printing process very simple principle , which the silicone rubber cast by the steel intaglio printing head or intaglio graphic sensitive adhesive is transferred to the substrate. Pad can be used for a variety of flat or

Type printed materials , such as glass, plastic products, metal products , watches, and electronic , optical products. Its main feature is available for irregular shaped convex surface for printing, this is the use of

Other printing methods is difficult if not impossible to accomplish, and can be easily accomplished using the pad , and can realize multi-color fine print. This is for the apparatus, equipment , and the surface of the printed product is small

Ideal for printing. In addition, the printing stability, sustained , even after prolonged printing, printing precision will not change , and eliminating the drying process , continuous multi-color printing.

From the color of printing machines are mainly monochrome, color, four-color , six-color and eight-color , etc. ; from the degree of automation is divided into manual , semi-automatic and fully automatic type , etc., and also appeared in the current CTP system with

Conventional printing machines, making further increase the degree of automation . Here mainly from the overall structure of the printing machine , and some local key components of the current market, the main printing machine for analysis.

    The main types of printing machines.

    1 manual type printing machine

    This printing machine simplest structure , some people think that this machine should be on the market disappeared, in fact, until now a lot of high-end watches and other devices such panels are used printing machine printing

The . Of course, such machines generally do not appear in large printing companies , in many applications , but more small workshops . Its obvious drawbacks , such as low production efficiency , when a large amount of printing is difficult to guarantee

All the consistency of the quality of prints , but its operation is simple, small investment , so the market is still very active.

    2 open- ink tank printing machine

    Printing head can be moved up and down in it following a printing plate, ink tank ink is scraped the plate above scraping device , printing head and ink on steel contact . This design

Meter program is simple, widely used in high-volume of printing machine.

    3 Sealed cup system

    Such a system is considered to be universal in the past shaped pad design , a Swiss watch company has been using the system for 35 years . Ink mounted in a closed cup oil , the oil can move parallel to the steel cup

Board ink . When the oil cup directly above the plate, the ink can flow graphic part of the plate on the left when the oil cup , scraping the oil cup ring on the part of non-graphic ink scraped .

    4 Wheel transformation printing machine

    This structure is obtained from gravure to design , more suitable for printing single or continuous roll -type substrates . It consists of printing plates, printing ink tank and composed of silicone roller , roller type

Steel is dipped into the ink tank , the printing plate is rotated clockwise , the above inks were blown down , scrape ; printing rollers rotating counterclockwise , and steel drum on the pressure , so that the ink is transferred to the plate on the

The printing rollers ; eventually , printing rollers in contact with the substrate , the ink transfer is completed.

    5 hybrid printing machine

    This machine was originally designed for the ceramic printed using printing and screen printing in mixed form . The printing plate is not used , the ink is printed on the silicone coating by the following network , after which

Printing head in contact with the silicone layer , taken at the ink printed onto the final substrate . This structure combines the many advantages of screen printing and pad printing , screen printing as many can not complete the printing table

Surface ( such as double curved surfaces) of the ink and more selective than screen printing .

    6 satellites

    This is a printing machine designed to rotate in a plane on multicolor presses, controlled by the cam center , up to 750 revolutions per hour , if you can print four colors to 250 per hour , this machine suitable

Together in small print runs .

It consists of two rotating platforms and central control component parts . A platform placed substrates, put another platform plate . This machine is suitable for connection outside the single major companies, because these

Live parts printed volume is relatively small, it is multicolored , choose the model more cost effective.

    7 . Printing machine with CTP system

    In the field of printing , CTP are not new things , currently in offset printing , flexographic printing aspect has been widely used, even in the screen printing field , we could see the growing popularity of CTP .
