Screen Printing Process

By Anita Sung

Screen printing is a technique in which the ink is directly applied to the surface that is to be printed and this surface is called substrate. The image that is to be printed is transferred photographically to the screen in such a way that the areas not be printed is blocked and the fabric is used as a stencil. A roller moves across the screen stencil, pumping ink over the threads of the woven net in the open areas.

A stencil method of printmaking that imposes a design on the screen of silk surface, the ink is forced onto the printing surface through the mesh and the blank areas are covered with an impermeable substance is called silk-screen printing or serigraphs.

The screen printing first appeared in China during the rule of Song dynasty. The Asian countries started using the screen printing process in thirteenth century and advanced it further by combining the screen painting with block printing and paints. In late 1700s, the Europe started using the screen printing process but it gained wider acceptance much later as the silk was not available in the Europe at that time.

In the United States, the screen printing was popularized by artist Andy Warhol, he screen printed actress Marilyn Monroe in'62. A rotary machine was patented by Michael Vasilantone in'60 to print logos and team information on bowling garments but shortly, started printing on t-shirts. It was soon licensed by many manufactures for screen printing of garments making the rotary garment printing machine as a popular device for screen printing. In the United States, screen printing on garments account for almost half of the screen printing activity.

The screen printing was developed as an industrial technology but it was adopted by the artist for expressing and as a repeating medium to duplicate their works before '00s. This is a very popular in both the commercial printing and also by artists and it is used to print images on different mediums like CD and DVD covers, glassware, ceramics, hats, woodwork, metals, t-shirts and hats.

The first industrial screen printing process was patented in'07 and many years later, John Pilsworth of San Francisco introduced the multi-color printing using the same screen. In this, the different screen areas were blocked for different color inks and a multi-colored image was produced. This technique is popular in printing signs and posters.
