UV Varnish in Print: a Refinement Method for Best Results
What is UV varnish and what is the varnishing process?
UV varnish is a specialized coating used in printing, which is cured by ultraviolet radiation. What exactly is UV varnishing? This is one of the most effective print enhancement techniques, involving the application of a clear coating to the print to improve its aesthetics and durability.
Lakierowanie uv druku może być wykonane w dwóch wariantach – całościowym lub wybiórczym. Lakierowanie całościowe pokrywa całą powierzchnię arkusza, natomiast lakier wybiórczy jest aplikowany selektywnie tylko na wybranych elementach grafiki, co pozwala na osiągnięcie unikalnego efektu wizualnego.
Advantages of UV varnishing in printing
Aesthetic benefits of varnishing
UV varnish significantly improves the appearance of the print, giving it a:
- Gloss that emphasizes the intensity of colors
- Elegant, professional appearance
- Depth and contrast in graphic elements
The varnish forms a colorless coating that can be applied in different variations:
- Gloss – zwiększa nasycenie kolorów i nadaje powierzchni lśniący charakter
- Mat – tworzy delikatnie matową powierzchnię przypominającą folię matową
- Satin – oferuje złoty środek między połyskiem a matem
Protective properties of UV varnishing
UV allows not only to refine the print, but also:
- Protect from scratches and abrasion
- Increase moisture resistance
- Extend color life
- Facilitate surface cleaning
Types of UV varnishing
Overall varnishing
The process of all-over varnishing involves covering the entire surface of the sheet with UV varnish. This method:
- It is economical for larger expenditures
- Provides uniform protection for the entire print
- Gives a consistent look to the whole project
Selective varnishing (selective)
Selective varnishing is a precise method that requires the preparation of a separate file with the marking of places to be varnished. Selective varnishing allows:
- Highlight specific design elements (logo, headlines, images)
- Create a contrast effect between painted and unpainted areas
- Achieve an exceptional visual effect at a relatively low cost
Applications of UV varnish in various products
Chroma online printer and other printers
Today's printers offer UV varnishing as standard for:
- Business cards – lakier nadaje im elegancki wygląd i chroni przed zużyciem
- Catalogs – uszlachetnia okładki i istotne strony
- Posters – zwiększa odporność i atrakcyjność wizualną
- Packaging – chroni przed uszkodzeniami podczas transportu
Digital printing vs. offset printing
UV varnishing can be done with both technologies:
- Offset printing: traditional method, ideal for large print runs
- Digital printing: allows quick varnishing of small print runs with personalization capabilities
Technical process of UV varnishing
Preparation for painting
The process begins with:
- Graphic design analysis
- Prepare a file with the marking of varnishing places (for selective)
- Choosing the right type of varnish
Application and curing
UV varnish is used through:
- Precise application to selected areas
- Immediate UV curing
- Controlling the quality and uniformity of coverage
Kluczową zaletą jest możliwość natychmiastowej obróbki – wydruki są gotowe do dalszego przetwarzania bezpośrednio po wyjściu z maszyny.
