The screen printing machine S3P for printing glass sheets up to 200x300cm is equipped with solutions dedicated to glass printing such as the suction and blowing print table for easy handling and locking of the sheets and an electric positioning pin to simplify the positioning of the glass. Setup times are extremely reduced thanks to the pneumatic lock of the screen, squeegee and scraper which guarantee maximum repeatability, avoiding even the slightest movement. To optimize the printing time the length of the print movement can be adjusted from the panel.
