Also called screen print, screenprinting, is without doubt the most versatile of all promotional items printing processes.It can be used to print on virtually any material, including paper, cardboard, plastics, glass, metals and textiles.Some common promotional items that are stamped with silkscreen include pens, USB sticks, cups, keychains, pencils, t-shirts, polos, sweatshirts, watches, cases, bags and all kinds of textile products.The advantage of the impression by serigraphy, over other methods of printing and marking of promotional items, is that the press can print on materials of any shape, thickness and size, although used mainly for printing on objects that have a surface flat or relatively flat. 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. Screen printing is not only a method of printing fast and economical, also provides high levels of color and light fastness. Any other marking process allows the creation of so many color in virtually any material effects. All this is possible, because a variety of paintings of different compositions that can be applied on almost any kind of support and thickness can be used. Due to the simple application process, there is a wide availability of inks and dyes, superior to the other stamping process. 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. Silkscreen prints can be detected because each color has some prominence, and in the outlines of images path, such as texts, if we increase them, appear with a shape that recalls to the teeth of a saw. Another advantage of marking by silkscreen printing in promotional items, is that with the new automatic presses, large quantities of products can occur very quickly.
