Screen Printing - Flat bed Printing (Industrial)

Industrial flat-bed printing automates the screen printing process, with the fabric moved through the machine on a conveyor belt and the print repeating rapidly.

A green on yellow polka dot pattern is printed onto white fabric using two different screens: one with the yellow background and another with the green polka dot pattern on top. (http://www.bbc.co.uk/staticarchive/e880c9125cadaaa73a6cb155ecb96305abffa0c1.gif)

Screen Printing- Rotary Printing (Industrial)

Rotary screen printing uses CAD and roller squeegees. One roller is used for each colour. This is a very fast process used in the continuous printing of furnishing and clothing fabrics.

A green, yellow and orange striped pattern is produced by each roller applying a separate colour. (http://www.bbc.co.uk/staticarchive/10dd5cebf492b049123a35555ddfd792b1890be2.gif)
