SCREEN PRINTING

Commercial screen printing technology involves the production of a multitude of alphabets at a quick pace. Though one may note, even common articles of daily use make use of a printing application in some form or the other. Screen printing is suited for bold and detailed graphic designs. However, small and obscure particulars can also be duplicated. Modern printing technology is a good example of the rapid development in various commonly used devices and equipment in our life and the impact of science in improving efficiency.

Screen printing is a method used primarily for flat or relatively flat surface printing. The procedure involves a fine mesh or screen securely stretched around a stiff frame. Sections that are not to be printed are blocked on the screen. To create a print, the screen is placed on a piece of dry paper or fabric and ink is placed on top of it. A rubber blade is used to spread ink uniformly across the screen. The ink passes through the open spaces in the screen onto the paper or fabric below after which the screen is removed. The screen is usually durable and long lasting and can be re-used after cleaning.

If more than one dye is to be used on the same surface, then the original ink must be allowed to dry before the process is repeated with another screen of the same design and a different color of ink. The framed screen is positioned over the item to be printed along with a dollop of thick ink. In earlier methods, the ink was left to dry for long periods of time. However in modern times the printed article is passed through a heat-tunnel on a conveyor belt. This method guarantees that inks dry quickly, allowing the materials to be stacked or packaged almost immediately.

Properly dried screen print items are long lasting even in unfavorable conditions. If the printing surface involves darker items, usually a supportive base print is required. A light base color, preferably white is used. This method ensures that the successive colors retain their exuberance and are noticeable.

Today, screen printing is much more flexible than the conventional printing techniques. Screen printing inks are being used to print on a range of surface materials, which include fabrics, ceramic objects, metal, timber, paper, glass, and synthetic items. This has resulted in the usage of screen printing in diverse industries, from fashion garments to manufactured goods and labels.
