A noteworthy aspect of the screen printing, is that materials of promotional items, you can apply them thicker inks of what is possible in other printing systems.This feature, allows some very interesting effects that cannot be achieved with other methods of marking.

The silkscreen printing process consists of three elements: the display that carries the image, squeegee, and ink.
The process consists in transferring an ink through a mesh or screen stretched on a frame, the passage of the ink is blocked in the areas where there will be no image using an emulsion or varnish, leaving free the area where the ink will. The printing system is repetitive, that is, that once the first model has been achieved, the impression can be repeated hundreds of times without losing definition. Preparation of the display: to transfer the image to the screen, have to perform a series of steps: the client has to provide the logo, graphics or text that you want to be printed on the promotional item, in one of the digital graphics formats commonly used to be able to be vector. Using a printer, it has make the photolith, printing the image on a film or transparent support. Through the application of a photosensitive emulsion exposed to ultraviolet light, the image of the film will be transferred to the screen fabric. Finally washing the screen thoroughly, dissolving the areas of emulsion that were not exposed to the light, leaving a template in negative image on the mesh of the screen, being now ready to be applied on the promotional item to print. For each color used in a printout of an article promotional needs a different screen. Each screen can be reused for tens of thousands of copies.
To apply the screens on the promotional item to print, there are three types of printing presses: flat bed, cylinder and Rotary. Flat bed is the most commonly used.
