Screen printing the most versatile printing techniqueScreen printing is a less conventional printing process ,on any flat surface or surface with a large radius. The widespread use of screen printing begins with the ’70s, following the development of the paint chemistry and pigments and printing machines.

Screen printing is the process by which is printed on the base of different materials, starting from paper, ceramics, plastics and finishing with textiles and metal. What changes every time, depending on the specific media, it is not the process itself, but the type of ink. The basic rule is that the printing support to be smooth.

Screen printing is probably the most versatile of all printing techniques for it may leave a dense layer of ink on almost any material and the obtained ink layer thickness is the greatest, compared with other types of printing. The ability to print variable ink densities with a large amount of pigment create very bright colours, with fluorescent effects, able to withstand extreme temperature and humidity.

This can lead to special effects that can not be obtained by any other technique or priting machines, but only with those specialised in this field. The process itself is simple and consists in applying on the material to be printed a layer of ink through a screen. Preparation begins by stretching perfectly the mesh of the net and attaching it to a rigid frame so that it stays smooth and unwrinkled.

Non screen image must be blocked and the image to be printed open, to allow ink transfer on the material. The image made by screen printing consists of a number of points which is given by the number of the screen’s mesh on which the mask is done.

The finest screens that are used have the maximun number of 300 stitches / inch, which determines the maximum resolution that can provide screen-printing to be 300 dpi. It cannot be compared to the resolution obtained when using offset (2400 dpi) but still the quality is fine. As a technique , screen printing is familiar to many of us especially because of the promotional items.

Very few know, however, that this technique is used also in printing self-adhesive labels. Besides this technique is the one preferred for luxury labels. Some of the advantages of silk-screen printing are: printing in small and medium series, high resistance of the paints to friction , scratching and especially UV.

But if somebody aims at higher standards, by printing multiple copies in an efficient way, a screen priting press is required. Even so, there is nothing to worry about because many companies offer from simple to sophisticated presses and there is certainly one place where everybody can find one to satisfy their needs:

These equipments are used to print in one or more colors ,in manual mode, semi-automatic or automatic mode, printing of different products, cylindrical surfaces, flat or irregular. Such systems are widely used for printing pens, lighters, glasses, toys, various containers, paper and cardboard, books, frames, industrial products, textiles, etc
