Print Technique: Reflecting on Strike-Through Varnish
When most of us want to add additional flair to our print project, we automatically look for elaborate finishing processes to help us accomplish this, forgetting that a well-designed spot varnish can really take the perception of quality and design up a few notches. Unfortunately, most people look to spot UV to hit this mark, since it’s immediately recognizable based on its high-gloss, wet-look appearance.
Spot UV’s Dirty Little Secret
While spot UV truly does produce a beautiful product, it’s sort of like the Las Vegas of the print world…..all the glamor and glitz, with lots of dirty little secrets. First, it’s a petroleum-based product, and the last thing any of us need is for your postcards, business cards, or annual report to further our dependency on foreign oil. Second, spot UV can be very expensive and typically runs off-line, as an additional process.
So, why bring it up if I’m only going to talk you out of using it? Because I can offer you a comparable, but much greener process!
Go Greener with a Strike-Through Varnish
Here’s how it works: The contrasting glossy vs. matte effects are accomplished using our water-based coatings and a strike-through varnish, printed as an ink, inline on our presses. First, the dull/matte strike-through varnish is put down with a traditional printing plate in the areas that are to stay matte. At the end of our presses, an overall flood of our gloss aqueous coating is applied.
As it cures, the gloss coating is dulled down in the areas where the strike-through matte varnish had been applied. Also, since we’re using a traditional printing plate in a standard print unit on our press, we can achieve as much detail as we want. Otherwise, you have to cut a coating blanket specifically for the areas where you want glossy, and that blanket can only be used for that press run or project.
When designing for this, remember that, because it’s a water-based setup, the contrast is not as dramatic as the petroleum-based UV. However, keeping the varnish design on a darker, solid-color background will ensure you get the maximum amount of visual appeal out of this process.
