THE ART OF SCREEN PRINTING – CUSTOM LOGOS

Screen printing is the process of forcing ink through a mesh screen onto a surface. Making some regions of the screen impenetrable to printing ink results in the formation of a stencil, which prevents printing ink from passing through the screen. The printed image is formed by the ink that flows through. A printing screen is made of a thin mesh fabric that is stretched tightly and fastened to a metal or wooden frame. Traditionally, these screens were made of silk, but nowadays, synthetic materials such as terylene are used. 

Stencils, which can be made of a variety of materials such as fabric, greasy paint, or a design on a transparency, can be applied to the screen in a variety of ways, including placing them directly on the screen's surface, painting them on the screen, or transferring a design onto the screen using a photo-sensitive emulsion. The most popular modern approach for preparing a screen is to transfer a design from transparency or Mylar film onto a photosensitive emulsion. Designs can be created in a variety of techniques, including hand-drawn with opaque ink, printed onto transparency, or cut out of rubylith, an ultraviolet-masking film. 

STEPS OF SCREEN PRINTING: 

1. To transmit the graphic from the clarity, a scoop coater, a metal trough with a clean, even edge, is used to coat the screen with a thin layer of photo-sensitive emulsion. 

1. After the emulsion has dried, the pattern is applied to the screen. 

1. The screen is subsequently placed in an ultraviolet (UV) light-emitting exposure equipment. When the exposure unit is turned on, the design prevents UV radiation from hardening the emulsion around the image. 

1. The design's emulsion remains soft and is drained out of the display, leaving the picture on the computer monitor. 

1. Once the screen is ready, it is placed in hinges attached to a board or screen printing table with hinges at the top and holes in the surface that allow a vacuum to keep a sheet of paper in place during printing. A large bead of ink is sprayed to the inside of the screen and then pushed uniformly across the image with a squeegee, a process known as "flooding the screen." 

1. A piece of paper is then placed behind the screen, and ink is pushed through the sections of the screen that are not blocked by the stencil with another pass of the squeegee. The resulting perception follows the matrix's orientation. 

1. If the composition calls for more than one colour, the printmaker must repeat the process with a new stencil for each colour. The printer must take preventive actions to ensure the proper conformity of the paper page and the screen in order to keep the colours of the composition aligned. 

BOTTOM LINE: 

Screen printing produces higher-quality results than digital printing. It is more robust for long-term prints and may be used on a wide range of printed books, including glass, wood, fabrics, signs, banners, electronics, and many more.
