Silk screen printing is a permeographic printing technique that today uses as a matrix a polyester fabric stretched on a wood or metal frame defined as a screen printing or silk screen frame.

It is a high quality printing technique, characterized by a long process of preparation.
Screen printing is the only printing system that allows you to print on any material.

The passage or permeation of ink from the top of the serigraphic frame to the print surface below, through the screen printing fabric is effected by a slight pressure passage of a bar with an elastomeric polyurethane board which is supported on the ink and presses the latter through the printing fabric through a sliding motion.
This bar is defined as squeegee or squeegee for screen printing.

This print action can be repeated cyclically by hand or by means of special screen printing machines, reaching a high production speed that can meet depending on the equipment available to the industry or craftsman.
