Now the water transfer printing method more popular, especially for Helmet Printing, Mug and other material printing with round shape. Water Transfer Printing is very easy to transfer to other media like helmet, so the process more efficient. Water Transfer Printing also called as curve coating printing (a printing method for print at surface that is not flat) this method overcomes the problem facing offset printing that can't reach the tongued and grooved face and the disadvantage from paying higher expense for the equipment. Water Transfer Printing process can be applied to surface of the materials such as ceramic, wood, plastic, fiber, stone, hardware, glass, metal, etc. The cost for applied with this method is relative low, while their added value multiples.

The Offset Printing Offset printing is the most commonly used printing method today. More than 50% of all printing jobs is using offset printing technique. Offset printing works with a simple manner. Offset printing uses three cylinder to transfer the printed image to the substrate. First cylinder in offset printing is mounted with offset printing plate. The image on offset printing plate is readable. The first cylinder inked and transfer image onto the rubber blanket (second cylinder). The image in rubber blanket is unreadable. After that image transferred from rubber blanket onto third cylinder or the substrate. Substrate is mounted on the third cylinder or The Impression Cylinder. The image in Impression Cylinder becomes readable again. Image in offset printing have a unique characteristic, the printed image and non-printed image are on same surface level. The printing method used a chemical process that ink and water not mixed from a single surface level. In fact, offset printin...

Screen Printing Technique A screen is made of a piece of porous, finely woven fabric called mesh stretched over a frame of aluminum or wood. Originally human hair then silk was woven into screen mesh; currently most mesh is made of man-made materials such as steel, nylon, and polyester. Areas of the screen are blocked off with a non-permeable material to form a stencil, which is a negative of the image to be printed; that is, the open spaces are where the ink will appear. The screen is placed atop a substrate such as paper or fabric. Ink is placed on top of the screen, and a fill bar (also known as a floodbar) is used to fill the mesh openings with ink. The operator begins with the fill bar at the rear of the screen and behind a reservoir of ink. The operator lifts the screen to prevent contact with the substrate and then using a slight amount of downward force pulls the fill bar to the front of the screen. This effectively fills the mesh openings with ink and moves the ink reservoir t...

Relief Printing Surface of print area higher than not print area. It's mean ink not reach the unprinted image. Sample : Woodcut; Linocut; Wood Engraving. Intaglio Printing Surface of print area lower than not print area. Sample : Engraving; Etching; Drypoint; Mezzotint; Aquatint Screen Printing Print using screen.
