FLEXO Magazine : January 2012
Since size does matter with regard to the actual filter ves- sel size, and the damaging particulate flowing through your system, the QUBE has a compact footprint and three levels of filtering. The QUBE is manufactured entirely from heavy duty 304 stainless steel. The design maximizes the filtration surface area and with a capacity of just over one gallon, it’s about the size of a 2-slice toaster. This large capacity means it’s pos- sible to run for multiple days between filter changes. Each G2 QUBE includes an integrated rare earth magnet located at the ink entry port and a vertical / horizontal mount- ing bracket. Floor stands are available if that better suites an application. The specially designed non-woven filter bags are available at 50μ, 100μ and 200μ to support all solvent and water based inks and coating applications. The bag fibers will not “pill” and co-mingle with ink like similar non-woven bags currently on the market. So whether you need a coarse filter bag for heavy metallic inks and coat- ings, or a more refined filter bag for high- graphic printing, the QUBE offers greater versatility. Since one of the biggest nuisances of using a filter vessel is knowing when to change the bag, the vessel includes an onboard, easy-to-see , back pressure gauge positioned in the vessel’s lid. When the gauge reads 15 PSI, it is time to change the bag. Some applica- tions use a bypass system that allows you to change the filter bag without shutting the press down. The QUBE is also receiving praise from industry insiders in real world practice: “In spite of running a popular in-line filter with a magnet, my client was repeatedly stopping the press every two hours due to streaks,” says Greg Mercier, process improvement consultant. “ Produc- tivity was low so we tried the G2 QUBE by placing it after the filter currently in place. The results were astonishing. The press ran 12 hours without stopping and we couldn’t believe the amount of debris captured by the QUBE. It caught fragments that even passed though the original filter. We immediately ordered enough units to equip every print station and they have already paid for themselves,” maintains Mercier. n About the Author: Mark Johnson began his career in flexog- raphy 15 years ago as a field service technician for a major ink company. During that time he dealt with the conse- quences of inks not filtered on press. Since joining FLXON INC in 2007 in marketing and sales, he conducts in-plant operator best practices training and has presented at industry events around the country.

Bold words? You bet. And here’s why: Apex reinvented the very concept of ink-to-plate transfer and, from the ground up, perfected a whole new surface geometry, a whole new ceramic composition — and a whole new world of flexographic printing possibilities. We call it GTT: Genetic Transfer Technology. Dot gain, pinholing, haloing, mottling. You’ve come to expect these foes on-press and you do your best to combat them, but because flexo is an imperfect art, your results often vary. Wouldn’t it be nice to master one problematic variable: ink-to-plate transfer? Historically, a prime limiting factor in print quality, press speed, and workflow is the anilox surface where ink meets plate. Apex has met that challenge head-on. Just like the mechanically-engraved chrome anilox before it, the capabilities of the conventional hexcell anilox have been outpaced by advances in presses, plates and inks — and by customer expectations. It’s time to evolve. And Apex leads the way with the invention of GTT, the patented successor to conventional anilox surfaces. The GTT ink metering surface is the proven evolution for this century. The GTT series includes UniFlexGTT for wide web, UniFliGTT for narrow web, UniCorrGTT for corrugated applications, and UniCoatGTT for coatings/offset. Discover how our three revolutionary technical innovations deliver unrivaled precision, durability and the freedom to consistently print your best work every day without sacrificing time, focus or profitability.

Meet UniFlexGTT for wide web and UniFliGTT for narrow web — the future of flexographic ink metering technology. Imagine requiring just two or three GTT surfaces to replace your entire stockpile of hexcell anilox rolls/sleeves. Imagine: use the same surface for fine screens and stronger solids — on fewer ink stations at higher speeds. Go ahead and streamline your pressroom. Gain unparalleled print quality and consistency. Free your bottom line to soar. And re-imagine your future. Is this an evolution in flexo? More like a revolution. Bold words? You bet. And here’s why: Apex reinvented the very concept of ink-to-plate transfer and, from the ground up, perfected a whole new Slalom Ink Channel surface geometry, a new hybrid ceramic composition and a new laser engraving process.
