Pad printing machine is a printing machine that uses a soft and variable silicone rubber head to transfer the ink on the printing plate to the product. Compared with offset printing, gravure printing, and flexographic printing in the mainstream printing field, the pad printing machine is a printing machine with a simple structure. machine, but its adaptability to products is very wide: 1) It is the most adaptable and accommodating printing machine to product shape, it can adapt to any irregular convex surface, concave surface, stepped surface, etc. rubber head can touch 2) It is the printing machine with the strongest adaptability to product materials: it is suitable for almost all types of paper, plastic, ceramics, wood, glass, and metal.
    The name of the pad printer comes from its use of "Pad".
    Pad printing machines are developing rapidly now, and they are more and more inclined to multi-color, servo, automation, and intelligence. Various pad printing machines designed for specific products have emerged as the times require, constantly promoting technological and market changes.

Pad Printing Process


         Coating ink onto the pad plate by an ink roller or sealed cup

        Opened-inktray pad printer stores ink in the end of the tray, when the roller slide into the ink and out will bring ink to the pad plate; sealed cup pad printer stores ink in the sealed cup. Sealed cup moves from back to forth and brings ink into the cave of pad plate. 

     2.Removing ink: 

     Removing ink on the pad plate with steel blade or sealed cup

        The ink in the cave of pad plate will remain. Removing the ink on the surface of pad plate completely is very important. when the ink remain on the surface of pad plate, pad will pick up them with the ink in the cave of pad plate, printing picture will be not same as standard document.  Removing ink with steel blade on  inktray pad printer and Removing ink with Sealed cup on Sealed cup pad printer.

       3.Picking up ink

       Pad above the pad plate press down and pick up the ink from the cave on the pad plate, then rise up. The ink will be transfered onto the pad surface because of pressure. Please make sure the size of rubber pad is matched with logo.


       Pad move to the position above the working table and substrate. There are two kinds of moving way: one is parallel moving, the other is turning moving. Most of KC brand pad printer drived with pneumatic -controlling.


       Pad press down to contact the substrate and print inks onto substrate. Substrate is installed on the fixture and the fixture is installed on the working table of pad printer.


Pad Printer/Tampon printer

Used to print small area and complex surface of industrial products. Pad Printer is consist of working table, pad combination, ink supply system, operation controlling system and machine body as well.

  • Structure

             (1) Working Table

      Install fixture and substrates. There are Four kinds of working table: base, shuttle, cylinder and conveyer. Base working table is one simple working table to install conveyer and shuttle. Shuttle working table and conveyer working table installed on multicolor pad printer. One product to be installed and printed on shuttle pad printer and more products to be installed and printed on conveyer pad printer, but shuttle pad printer printing precision is higher the conveyer pad printer, cylinder working table is suitable for printing round objects.

    (2)Pad Combination

        Install pad to pick up ink from pad plate and transfer onto the substrates. The pression of pad adjusted by the slide switching beside pad printer. When starting pad printer, pad combination will move from plate above to substrate above. Most of pad combination press down controlled by one cylinder jar, in order to print small area on big dimension objects, Independent press by diffrent cylinder jar will reach the result, this is independent-press muti-colour pad printer

      (3)Ink Supply System

       There are two kinds of ink supply: one is opened ink tray, the other is sealed cupInk and thinner covered in sealed cup to provide and avoid harmful solvent volatilization to protect environment clean, meantime ink saved because of small volatilization. In order to improve printing quality, installing Pad-cleaning tape device with ink supply system. when the rubber pad move back after printing and print on the adhering tape, The printing Quality will be improved obviously.

   (4)Operation Controlling System

         Most of pad printer controlled by micro-computer built in to make machine stability and easy to operate. When testing, only press simple action key and when starting automatic key to begin printing will be helpful to operate pad printer.

  •  Main Factors

        (1)Pad Plate

       Three kinds of pad plate used by pad printer: thick steel plate ( Open inktray pad printer and closed cup pad printer), thin steel plate( Sealed cup pad printer), nylon resin plate(Open inktray pad printer and closed cup pad printer).

       (2) Pad Ink

       Choosing solvent screen ink, UV pad ink and solvent pad ink according to products substrates and having a test before printing. KC Printing machine limited can provide Marabu , LOGO, ALPHA, KC pad printing ink.

       (3)Rubber Pad

        Ink picked up from plate and printed by soft rubber pad. Choosing pad according to substrates and printing precision, more harder pad to get more precision printing quality.


        It is important to make fixture according to products. Regular products need the fixture made by lathe or CNC. Complex products need the fixture made by polyester resin-Putty.

  • Types

        1. Manual controlling(404M) , Electron controllingCompression air controlling pad printer (P2-408C) to be sorted according to action supply. Most of pad printer in china market is controlled by compression air.

        2. Sealed cup pad printer( SP2-41010C), opened ink tray pad printer (SP4-40616) to be sorted according to different ink supply system. Sealed cup pad printer have more excellence than opened ink tray pad printer such as ink viscidity, ink dosage and clean environment.

        3. One colour( P1-408), two colours(P2-606) , four colours(SP4-408), six colours pad printer (SP6-40618) to be sorted according to max printing colour numbers. One colour pad printer print one colour one time; two colours pad printer print two colours in one products one order to improve multicolor pad printer purpose, one colour to be printed one time is ok too.

       4. Shuttle working table pad printer (SP4-406) and conveyer working table pad printer (SP4-40616)to be sorted according to different working table installed. Shuttle working table pad printer install one product to print and get multicolor. Printing more precision than conveyer pad printer. Conveyer pad printer install 10-20 products to print and get more higher production than shuttle pad printer.

       5. Flat pad printer and cylinder pad printer (P1-604S) to be sorted according to products can be printed. Cylinder pad printer updated on one colour pad printer. When its pad press down on the product and keep contact state for some time, shuttle working installed move and make cylinder product move round. Cylinder pad printer can print some simple round products such as handle, golf ball.
