Maximum versatility with screen printing technology
This process is used to customize items made of cloth, leather or leather substitutes, ensuring their decoration in vibrant colors. Without the help of this precious technology, these objects would be very difficult or impossible to print by another technology, either because of the material from which they are made, due to the complexity of the graphic elements to be printed or due to the shape of these objects. The screen printing thermal customizations are of very good quality ensuring a very high printing accuracy and an increased resistance over time, and the associated benefits being a very good visibility and a remarkable impact for the printed brand.

Large format screen printing
It differs by the large printing area and the appropriate size of the equipment – it exceeds the size of the format 70 х 100 cm.

Technological aspects. Available procedures:
