Specialty Coatings - Not Your Standard Label Varnish

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.

Packaging and Flexo Labels: We have an Application for that!

Packaging and Flexo labels going on packaging are a very common subject at Label Tech Inc. The application of the label on a package can make all the difference when it comes to the printer's choice of materials such as face stocks, adhesives, laminates, and even varnishes. Is your packaging flexible or firm? Are you applying a label to a box, a jar, or a bag? What is the temperature of the product that we are putting the label on? These are all key elements in determining what materials and adhesives we will be printing on. A company that truly knows their product should be able to answer all of these questions with ease. Now let's dive a little deeper into this subject.

Typically, if we are talking about packaging and labeling, we need to discuss the preparation, transport, warehousing, sale, and end use of your product. All of this information is relevant to your business and to your label company. For instance, a label may appear to have enough protection with a simple UV Varnish on it, but if it is shipping across country with no dividers in the box separating the product the varnish may wear and cause your label to de-face. On the other hand, if your product is going to be labeled for use in a freezer then you may want to consider using a freezer grade adhesive. If you were to use a simple permanent adhesive then the label would most likely fall off of your product. If you are labeling in a freezer and then the product is going to be put in a room temperature environment then you definitely are going to want to laminate it to prevent condensation from ruining your label. Removable adhesives are popular for putting a label on a product that you want the customer to be able to easily remove- didn't see that one coming huh!? If you are going to be machine applying labels and want the ability to peel a label off that goes on crooked and then put it back on straight then you may want to consider using a "re-positionable" adhesive.

There are many face stocks and adhesives that can be mixed and matched based on the specific need your product has. When you are choosing a commercial printer you should try to find one that has a good working relationship with their stock supplier. This can mean all the difference if you have a special label application need. The printer can easily bring in their supplier to ensure your label is going to stick how you need it to.

Other things to take in to consideration can be simply overlooked and cause big problems later for your product's label identity. For example, if your label is going to be exposed to extreme heat at some point in it's lifetime then your printer is going to need to know. An example of this type of label could be something that is going on a furnace or hot water heater. There are many things to take into consideration when talking to your printer about your label. If you are lucky, then you will stumble upon a printer with employees that are already in the know about what questions to ask about application. Who knows, the printer you are looking for may be right under your nose!

Always Use Protection- We Are Talking about Labels!

Recently I sat down with Peter Mullen, Plant Manager at Label Tech to discuss the differences between varnish and lamination. Protecting the inks on pressure sensitive labels is easy when you know the application. Here is what he had to say.

How do you decide which is the best way to protect your label while at the same time giving your product the appeal that allows it to stand out on the shelf? The answer to this question depends on what and how the label will be used. The advances in both varnish and lamination over the past several years have made it possible to enhance your label esthetically while at the same time performing a function such as printability or water and alcohol resistance.

One major factor in considering the issue of protection is what the label will be going through during filling, labeling, packaging and shipping of the product. In most cases this will be the most abuse your label will experience in its life span. In the extreme case lamination may be the way to go as it is almost bullet proof when it comes to protecting the material and ink underneath it. Lamination however will more than likely add slightly to the cost of the label.

If you prefer a varnish it is possible to vary the coat weight in order to enhance the protection level.  You may also want to consider a varnish that is glossy rather than matte so it will have some slip properties to it. There are many varnishes on the market besides those that perform a practical function such as glitter for special effects or embossed to give your label a 3 dimensional look. There is a product for almost anything your imagination can come up with.

At Label Tech Inc we stock a wide variety of varnishes and laminations to cover most requirements our customers may have. When one of our customers has a particular requirement that may sit outside the norm, we have the ability to work closely with our vendors in order to develop a product that will fill that need.
