Please discuss your options with our experienced packaging experts to choose the print coating that is perfect for your custom packaging solution!
 

Overprint Varnish

Applying varnish is an inexpensive way to add gloss to your printed pocket folders. Although not as hard as other coatings, varnish does offer some protection; mainly resistance to dirt, smearing and water.
 
Varnish can be applied two ways; overprint/flood (applied over entire printed surface for protection) or spot/pattern (applied to select elements for emphasis). Varnish can also be color tinted.
 
Gloss varnish reflects more light and adds to the sharpness and saturation of images while matte or dull varnish increases readability by diffusing light and reducing glare.
 
This economical folder finish provides a mild shine and protection but can yellow paper over time.
 

Aqueous Coating

Aqueous coatings are fast-drying, water-based, protective sealants particularly resistant to smudges and fingerprints. Aqueous formulations afford greater protection than varnish and have gloss characteristics that fall between varnish and UV coatings.

A high gloss finish has less rub resistance and conversely, greater rub resistance reduces the degree of gloss. They are not water/liquid resistant because the cured coating does inhibit complete drying of the inks on the folder.
 

Advantage of aqueous coating over conventional varnish:
  • Higher gloss
  • Better clarity
  • Faster drying
  • Will not yellow with age
  • Higher abrasion
  • Higher rub resistance
  • Environmentally friendly (water-based)
  • Glossier finish on lesser grade papers

Laminate

Laminates come in two types, film-based and liquid-based. Either a clear plastic film is laid down over the sheet of paper or a clear liquid is spread over the sheet and dries (or cures) like a varnish. Laminates protect the sheet from water, are slow to apply and costly; but provide a strong, washable surface.
 
Film lamination features high gloss with a very smooth, tough finish. This durable plastic film has advantages over liquid coating at a slightly higher cost. Film lamination will not yellow with age, flake off, and is scratch resistant. In addition, the ink is protected from cracking and provides an odorless/wipeable surface.
 

UV Coating

UV coating is a liquid based, protective coating which is applied and cured by ultraviolet lamps leaving an extremely high gloss hard finish that is chemical and abrasion resistant. UV coatings are solvent free and emit no VOCs (volatile organic compounds).
 
Drying is instantaneous with exposure to ultraviolet radiation. Spot cover, raised effects and a very heavy coating for extra shine and protection are possible.
 

Advantage of UV coating over other coating methods:
  • Highest gloss
  • Better clarity
  • Higher abrasion
  • Higher rub resistance

Printing must be done with UV inks or inks that do not contain micro crystalline wax (also called wax-free). Pigments must be heat and chemical resistant. If nonresistant colors are used, the color may fade, change or bleed into unprinted areas.

It is more difficult to recycle than the other coatings and this thick coating may crack when scored or folded.
