Silk screen printing from its first days until today has not changed much in the technological sense; principle of work is the same. Innovations have been introduced by some other industries like chemical industry and introduction of computers and their improvement so that quality of print has been better and time of preparation became minimal. Silk screen is used for decoration of fabrics, metals, various objects of uneven shape, pencils, and lighters, printing on various stickers and foils and already finished products... Principle of work is the following: cliché for printing is aluminum or wooden frame that can be produced in various dimensions (A4, A3, B2...). Fabric made of polyester is stretched on the frame. Sifter is spread by emulsion which, when dried, blocks the pores on the sifter. Printing motive is made on film or tracing paper and attached on the sifter, after that exposed to the light or UV rays. The sifter itself is washed from the emulsion to leave open the holes on the places where the light could not reach. The sifter is placed on the machine and printing process can begin. To get the print, object on which the printing is done is placed under the frame with certain positioning, frame is lowered and by going with doctor blade over the sifter color goes through the holes leaving the print. In this technique PVC colors are used so it is advised that the room in which the work takes place is well ventilated.
