Screen Printing    

The screen printing technology is universal and sometimes it is sued instead of the offset printing. In card production, it could be used for making signature space or scratch panel. Screen printing is used for the metallic colours and its combination with offset printing results in perfect visual effects.

The positive film is copied with a contact to a fine screen covered in photosensitive emulsion, which, as a result of the exponation, opens some of the holes in the screen, while others are left closed. After that, ink is put over the screen, and the item, which is to be printed, is positioned under it. With pressure, ink is supercharged to the screen, and in the places, where the holes are opened, it goes through it onto the printed object. Screen printing does not have shades, and if they are necessary, rasters are used. Differentiation capacity of screen printing is lower than the one of the offset printing, which is why rasters have to have bigger points. Thats why screen printing application is not used so often.

Screen printing's strong point is that it could be used on many surfaces. Unlike offset printing, it could be used on very think cardboards, wood, plastic, textile, metal, self-adhesive PVC folio, as well as objects of irregular shape diaries, pens, boxes etc. It is used mainly when offset is technologically inapplicable or in printing preparation when a small number of the items has to be printed.
