Screen Printing

The main basis of this methods is similar to those of all the other print processes, as you have to separate the colours onto different screens to form a way to layer the design together. Although this is an extremely versatile process, allowing you to print onto a larger number of stocks with greater strengths of ink. Providing mixed qualities to work depending on the design.


SCREEN


Any image that you want to print with this method needs to be fixed to a screen. The method of doing this is to use ultraviolet light the burn the image onto a resin, which in turns sets leaving the appropriate image visible. The material used is formed from a mesh, stretched over a metal frame. It can be washed and reused creating a cost effective and traditional way to printing.

The ink is pulled across the screen in one direction to apply onto the print, then moved back in the other to take it off. Using a 'squeegee' to push the ink over the screen, the mesh allows only a certain amount to be pressed through, creating a print. This is then left to dry until another layer can be applied using the same method.

ROTARY SCREEN PRINTING

This process uses the basic fundamentals of normal screen printing but instead it's used on a more industrial scale, to create much greater batches of print work. Each screen rotates round one another form a systematic sequence where colour can be applied much more effectively than having to manually change the screen each time.
