UV varnishing

Description

This is one of the most popular techniques for enriching substrates used in the printing industry. This process involves covering the surface of different substrates with a varnish layer, which is then cured with a special electromagnetic wave lengths of the spectrum - is commonly called UV light.

The types of UV varnishing can be represented by multiple categories. The most common division due to the type of varnish used and so we distinguish here: glossy, matte and special . Because of the manner and method of varnishing: flat and spot (so called selective varnishing). All types UV varnishing processes offered by us are described in dedicated tabs.

Features

• Increases the durability of prints - protects the surface against mechanical factors - eg. scratches, abrasion of the ink, moisture.
• Gives striking appearance - increases the attractiveness of the final print by highlighting selected items or the entire surface of the work. For example by matting, giving gloss or giving a special surface structure or another special effect.
• The revival of color - skillful use of UV varnishing can emphasize the color of selected areas on the print.

Technology

UV varnishing technology at Pasja
We rely on efficient automatic screen printing cylinder lines and semi-automatic machines. This configuration of machines give us the opportunity to implement a number of orders with low print run and high-volume production of various formats in a short time. Being the pioneers of the use of UV technology in screen printing on the Polish market (1993) and based on our more than twenty years of experience, we have built machines park designed to meet the most demanding expectations of our clients, both in terms of quality and quantity.

Substrates for painting
Theoretically and practically we can varnish over all, under condition that the substrate is flat and provided in sheets with a diameter of not more than 1020 x 740 mm and a thickness in the range from 0.1 mm to 100 mm. Most often we varnish paper, cardboard and plastic, not infrequently also wood, metal and glass.
Most common we put UV varnish over the covers of books, magazines, brochures and catalogs, as well as leaflets, folders and business cards, calendars. UV varnishing is widely used in the production of packaging. Varnishing of sheets of glass, wood or metal has many uses including in construction and industry. It is widely accepted that is possible to varnish an absorbent surface, eg. uncoated papers and cartons. The technologies we use allows to break the stereotype and create interesting effects on such materials.

Designer's tips

Tips for designers. How to design?
First of all, remember that generally is not recommended to varnish elements smaller than 0.2 mm in the positive and 0.6 mm in the negative. In the process of screen printing paper just a little pulls and in the case of small parts varnish does not appear in the place in which it was designed. While here, we can boast that under certain assumptions, thanks to our experience, we know how to ensure perfect application of spot varnish on components smaller than those indicated above.
Keep in mind that although it is accepted to rasterize UV varnish, we at Pasja know how to do it and we can achieve a lot of unique and special effects. This ability has already provided us with many very satisfied customers and some very prestigious awards.
