Even people who have nothing in common with printing can tell the difference between low and high quality printing. Often, not only good quality paper and ink, but also the use of different kinds of printing refinement methods is behind good-looking publications. What are these methods?
What is print refining?
In a nutshell, print finishing involves coating the print substrate with various types of substances to give it a more interesting, unique look. It makes a publication stand out from others and attracts the attention of potential clients It also helps to increase its resistance to mechanical damage and adverse conditions such as moisture or intense sunlight.
There are many refining techniques that can achieve a variety of effects - laminating, embossing, coating, impregnating, gumming, bronzing, off-steel varnishing in London and many others.
Benefits of offset varnish
Above all it is a method that allows to improve the quality of printing. A layer of lacquer protects the publication from minor damage such as scratches. It also protects the paint from loss of its properties - fading or abrasion. It increases the impression of printing thickness - for example, in the case of book covers made of lightweight paper what is more it also improves the appearance, positively influencing the colour intensity of the previously used ink.
Depending on the lacquer used and the lacquering technique we can obtain gloss or matt, it is also possible to obtain the so-called 'pearl' gloss. The most popular varnishes used in printing houses are:
UV varnishes - polymeric varnishes, cured by UV rays, containing various types of modified resins.
Oil varnishes - produced on the basis of vegetable and mineral oils. They can be matt or glossy, there are also colourless oil varnishes available on the market.
Dispersion paints - dry by soaking and evaporation. Both matt and glossy lacquers are available on the market. Thanks to dispersion varnishes, it is also possible to obtain the effect of increasing the slip of the printed sheet, so that the sheets do not pull each other.
Print substrates can be varnished either completely coated with ink or only partially coated. A popular method is also spot varnishing - then only selected, graphic areas are varnished. Many printing houses currently use offset varnishing in Birmingham.
Offset varnish in Leeds - what is it?
Offset painting in Glasgow is a method that has been used in the printing industry for many years. We distinguish between offset machines with a paint, water or lacquer unit. The varnishing can also be done by means of flexographic and gravure printing machines.
Offset painting in Glasgow can give a matt or glossy effect, depending on which lacquer we use. Matt varnishes are ideal for cardboard packaging or banners. Glossy lacquers, on the other hand, are perfect for printing glossy magazines and leaflets as well as labels for food and other products.
The great advantage of offset varnishing in Manchester is that it can be used in any printing unit, because offset varnishing behaves like ink. No additional painting tower is needed, as in the case of dispersion painting - this makes offset painting in Edinburgh a cheaper method.
Offset painting in Liverpool also has its disadvantages. This method is not suitable for painting surfaces that are intended for food contact. Offset painting in Bristol is also characterized by longer drying time of the paint than, for example, in the dispersion painting method - so it will not work if we want a very fast effect. Despite these disadvantages, offset varnishing in Cardiff is an effective and cost-effective method.
