Protect your printed piece!

Use of Coating techniques can not only be eye catching, but also, surprise them with a tactile WOW feel once they pick it up.

When adding a coating effect to your printed materials, you can really make a significant visual impact, as well as provide a level of protection. Over the years, many of you have asked great questions about which coating technique would work best for a particular design or project. I'm happy to tell you that I have a lot of experience working with these techniques and have a great collection of samples to share with you. Just give me a call and we can meet to discuss them in more detail.

For now, let's take just a couple of minutes to review the many different types of coating techniques.

Varnish can be run either clean/contaminated, wet/dry trap, as spots on its own, side-by-side, or as floods. You can choose from gloss, satin and dull varnish options, which can provide precise spot or overall application.

On the downside, varnish does not provide a great deal of protection, is susceptible to yellowing and is not environmentally friendly. You must also remember to allow for increased production time, due to the additional drying needed before printing the second side.

Aqueous coating can be done as a flood in gloss, satin or dull. Aqueous coatings provide good protection against fingerprints and will not yellow. This environmentally friendly coating is water-soluble and production time is quicker than with a regular varnish, as the second side can print immediately.

In the event you are looking for a spot aqueous, special plates can be made. However, an aqueous coating is difficult to spot-apply with precision, is susceptible to UV Burn, and requires at least 80 lb. text weight of stock.

Combining varnish with an aqueous can be accomplished by running one coating technique on top of the other (dry or wet trapped). Also called strike-through varnish, this technique is the most effective way to achieve a combined gloss and dull effect. The varnish provides a dulling effect while the aqueous coating provides the gloss.

Like all coating techniques, the nature of the printed piece dictates which coating will be most effective. Some excellent uses of this coating technique include call-to-action emphasis and highlighting specific areas within images, over products, or a combination of both.

A soft-touch aqueous coating is a unique technique that provides a very soft, rich and "velvety" feel. This process is fairly new and provides a softer look and feel to printed pieces, while significantly reducing fingerprinting. It is important to note that the darker the palette, the more muted the colors will appear. Soft-touch aqueous will definitely add a unique dimension to the right pieces.

Truly a tactile feel, soft-touch aqueous is a very unique coating effect that you must feel to believe! Call me today and I can bring you a sample to experience for yourself.

UV Coating is another nice coating technique that can be accomplished as a spot or flood in gloss or satin finish. It provides the best protection over other liquid coatings and will not yellow.

But it's important to remember that this coating technique can show fingerprints, is susceptible to UV Burn, can crack when folded, requires additional production time, and is not environmentally friendly.

Raised Spot UV Coating combines the look of thermography and UV blended together. This technique allows you to create very textural printed materials that can emulate substrates like leather, mesh, suede, canvas, cotton and many other tactile effects.

I have an extraordinary printed sample that employs this technique. It's an annual report that has the literal look-and-feel of an old-time leather scrapbook. Complete with raised and glossy sepia-tone photographs, this report really commands attention and draws the reader into the piece.

Sandpaper Feel

And speaking of creative printing effects . . . How would you feel if you picked up a piece that felt like a rough granular sand like texture? That’s right!! It could be used for environmental, outdoor, sporting products, stone / rock materials, etc. Can be flood and / or spot.

Paper MattersYour choice of paper stock has a huge impact on coating outcomes. Different paper stocks (such as coated gloss, dull, velvet, satin or matte) deliver various effect or impact for each coating technique utilized. Keep in mind that using an uncoated sheet typically will not yield any real noticeable effect or benefit of a coating.For more information, go to TK's Korner article "Picking the Right Paper and Substrate"
