Varnishing is the process of applying a transparent layer of silicon over a printed area. It can be applied to the entire surface of a printed item or to highlight a specific area of design, such as a logo.
This blog will explain all the various label varnishes available today.
Gloss Varnish It provides added gloss to materials and inks and protects printing from routine scuffing. It has excellent adhesion to both water based and UV curable inks on all types of substrates. A spot gloss varnish allows you to highlight specific areas of a printed piece and adds shine and depth to specific elements on the page, such as a logo or image.
Matte Varnish unlike gloss varnish, it is chosen when customers want the inks on the label material to look muted, dull, or soft. This coating was formulated to have a gloss of less than 5%, while preserving the colors of the inks beneath it.
Thermal Imprintable Varnish is an over print varnish designed for excellent receptivity of wax or resin-based thermal transfer ribbons. It was designed for flexographic applications on paper as well as plastic. This coating is also used in the tag industry for non-slip issues. Thermal imprintable varnishes are available in high gloss and matte finishes.
Soft-Touch Varnish is a high-viscosity coating that imparts a leather-like, almost rubbery feel with a rich matte appearance. Soft Touch coating has a finish that will flatten out color and contrast. It gives surfaces a very special velvety-soft feel. Soft-Touch varnish is suitable for application to entire surfaces or individual parts.
Braille Varnish is designed specifically for braille fonts, including those used for pharmaceuticals; when used correctly it meets current standards for dot heights. This varnish forms a layer on the surface to be felt to the touch and be able to withstand multiple stresses. It is vital that the braille dots be very robust in order to withstand the rigors products can face in transportation and to ensure they reach the customer in perfect condition. Braille varnish achieves excellent durability of dots on all types of substrates.
Glitter Varnish Metallic flakes of glitter can be used in combination with matte or gloss UV coatings. This type of varnish allows designers to create unique specialized effects in a variety of shapes, colors and dimensions.
Pearlescent Varnish is popular in the creation of luster effects, enabling new and unique color effects for automotive, industrial, cosmetic, pharmaceutical and other applications. This luster effect is caused by adding miniscule metal flakes to the gloss varnish, producing a pearlescent appearance.
Scent Varnishes can be applied directly onto labels or packaging as a spot coating and allow companies to incorporate scent directly onto packaging. Scent coatings are different from scratch-and-sniff, as that technology requires actual scratching to release the scent. Stock scents and custom scents can be developed for brands to give them a unique scent associated with the product. Hundreds of different scents are available, including Chocolate, Fresh Cut Wood, Bubble Gum and Suntan Lotion.
With all the varnish choices available today, be sure to work with your label printer to choose the right varnish for your project.
