Screen printing

Screen printing is most likely the most popular method of printing promotional t shirts, the set up process is similar to offset traditional printing methods where you need to provide your images in to separable colour files, for example if you have a four colour file you need to supply a CMYK file which the print production firm can break each colour down and isolate them from each other creating, four separate print images, one for the cyan colour, one for magenta and one each for the yellow and K being black or grey scale.

Now that the CMYK files have been separated a separate screen is produced for each colour in total four screens a C screen, M screen, and one each for the Y and K screens. So each colour has its own separate screen. After the screens have been produced and have been quality tested and all adjustments have been made they are mounted on to the screen printing press were each colour is aligned to the next using registration marks on the screens.
