Adding a touch of luxury and protecting the print from daily wear is the function of varnishes. Know now the types of varnishes most used in the graphic market.
The finish is the icing on the cake for every job. And in the graphic segment it could not be different. After all, almost all printed materials have some type of final finish, be it a lamination or other types of varnish, which is what we will talk about in this article.
At the end of these articles you will have learned what are the types of varnishes and the various aspects of this finish: what it is, how it is used, which type is most suitable for each impression, its importance, and the main advantages over other finishes. Come on?
Types of varnishes most used in the graphic market
What is varnish?
Varnish is a kind of transparent layer or film, which is on top of the various materials available for printing, such as paper. This layer ensures brightness and protection of the printed material against moisture and dirt, which increases its useful life.
It can be applied to the entire printed material or to just a few parts. For example, in a white pamphlet with red graphic material, perhaps the insertion of the varnish only in the red elements ensures the highlight and brightness necessary for the material, which avoids waste.
What is the importance of using varnish in printed materials?
As we said earlier, all the work with design and production is useless if the finish is not of quality. For this, some care is important to ensure the life of your print.
A well-finished material conveys excellent impressions, such as professionalism, credibility, care and organization. The result of the product may not be as good, but the finish increases its quality, pleasing and fulfilling its role.
What are the main advantages of using varnish in printed material?
Varnish is a very versatile material and can be used in different ways, in various types of paper and, in most cases, very satisfactorily. Low weight papers, which are usually more fragile to print, receive the varnish very well.
Another advantage pointed out constantly is the insertion of the localized varnish, as previously mentioned. This application occurs thanks to a specific technique, called localized UV varnish. One more advantage for you to consider the varnish for printing your materials!
What are the types of varnish available?
As already pointed out, there are several types of varnish that exist, which makes versatility a striking feature of this material. Because it adapts well to various types of products, it becomes a cost-effective option. We will now point out the main varnishes on the market. Compare!
Oil-based varnish
It is a material that closely resembles conventional inks, and gives either a glossy appearance, or a matte appearance to the material. Composed, generally, of oil resins, it has low cost when compared to other materials, and even to other types of varnish.
Because it is made from oil, it is very resistant to moisture, which potentially increases its durability. However, drying takes longer than that of other types of varnish, and it acquires a yellowish tone with natural damage and over time.
Their main use is in labels and packaging, as these products generally face moisture and the oil-based material resists it.
Water-based varnish
This type of varnish is a result of mixing water and other additives in its manufacturing process. Since it is liquid based, it is necessary to dry it after application. However, this drying is achieved quickly, due to the very base of the material – water.
Just like oil-based varnish, this varnish also gives either the gloss effect or the matte effect to the printed material.
Here at Gráfica KWG we work with the IR varnish option (infra-red). From English, infra-red means infrared. This is a type of water-based varnish that has a drying process by means of infrared lamps.
This type of varnish is ideal for those looking for a subtle gloss coating that at the same time fulfills the role of protecting and ennobling the print.
Its main advantages are:
- quick drying;
- greater protection for printed matter;
- immediate application during printing;
- gain of time in the following stages of production (cutting / folding);
- cost reduction compared to UV varnish;
- easier folding finishes;
- low environmental impact as it does not use petroleum-based solvents;
- does not emit polluting gases into the atmosphere;
- uses water as a diluent;
- uses water to clean equipment;
UV varnish
It is the most common among printed materials. Its name is due to the fact that its process requires the action of lamps that emit ultraviolet radiation (UV rays during the drying procedure).
This varnish stands out for having a greater brightness in relation to the aforementioned varnishes, which gives it a higher quality. It is more suitable for the manufacture of banners , folders and cards.
How important is it to hire reliable companies and professionals?
The process of building the material is very important and should not be done by anyone. In the same way, neither is the finish, since it is the one that guarantees the final touch to an entire work cycle.
So, look for good graphics, with the best equipment to print your materials. Hiring the right companies ensures the job is finished. Search a lot!
As you have seen, there are several types of varnishes, and each one fits a specific printing model for you. Because it is a high quality material, it is worth considering it always in your prints, to give a very tasteful finish to the work!
