4 GTT UniFlexGTT for Wide Web | UniFliGTT for Narrow Web | UniCorrGTT for Corrugated Bottom line? GTT is your new moneymaker. Here’s how: fewer rolls/sleeves are needed to handle more jobs. Higher quality product is delivered. With faster turnaround — at an overall operational cost reduction. Add these results together and watch your margins soar. Our customers worldwide have reported these advantages: IT’S LIKE ADDING ANOTHER PRESS — OR TWO When you run your presses faster – all the while freeing up stations – your net effect is the ability to print more jobs with the equipment you’ve got. SPEND LESS ON INK Our customers continually report dramatic ink savings due to the unique ability of GTT to use less pigment and/or more extender while achieving even greater print density and opacity. REDUCED SCORING AND BLADE WEAR Because less doctor blade pressure is applied and more ink is exposed to the blade resulting in higher lubrication, the risk of scoring is minimized. Plus, the superhard hybrid ceramic and slalom inkflow geometry combine to resist costly damage. FASTER DRYING TIMES Since you’ll likely be running thinner inks with GTT, ink dries on your substrate in less time. CRANK UP THE SPEED How fast can you go? Densities typically drop when running conventional anilox at high speeds and may even result in misting. Thanks to GTT’s surface release properties, the improved ink transfer of GTT enables more impressions per minute while maintaining stronger densities and curtailing misting. Don’t forget quicker setup times and reduced drying time. LONGER LIFESPAN With the benefits of reduced handling, a score-resistant surface and easier cleanup, your GTT will likely live a longer, healthier life in your pressroom than conventional anilox rolls/sleeves. CUT OPERATING COSTS AND DOWNTIME Do the math: when you replace two conventional anilox with just one GTT, you cut your costs in half: half the setup time, half the cleanup time, half the plate costs, ink costs, tape costs and blade costs. And half the risk of loss or damage. What’s more, you’ve eliminated registration on that deck. Now, multiply that savings across your entire operation — and decide how you’re going to spend your windfall.

Evolve your operation through GTT education. Investing in the best equipment is only one part of the big picture. To help you realize your full flexo potential, Apex is dedicated to empowering your team with the best training, practices and research to ensure you get the most out of your GTT upgrade. That’s why we support every GTT purchase with our Technical Education Program for your team, including UltraCare phone, online and in-plant support to help you fine-tune your GTT printing processes. Because GTT relies on advanced technology to achieve superior performance in printability and cost savings with consumables (inks, blades, tapes and plates), printers benefit most when they optimize five simple production processes to take advantage of GTT’s power. The Technical Education Program program enables users to master these five key performance variables to harness the power of GTT surfaces and make high-value adjustments otherwise impossible using conventional hexcell anilox surfaces. Every step of the way, our tutorials and real-time tech support make it easy to do your best work. STEP 1 GTT SIZE SELECTION Since the GTT series replaces all conventional hexcell anilox screen/volume combinations, it’s important for printers to choose the correct GTT size based on the type of print job (i.e., opaque white, combo, vignette, process). Our RangeFinder is a general guideline to help you specify an appropriate GTT surface for the job you’re printing. For example, when specifying a single GTT surface to perform on one ink station the tasks previously managed by two or more hexcell surfaces on separate stations, choosing the right GTT size is critical to your success. STEP 2 PLATE PARAMETERS Your successful choice of GTT size is dependent also on the plate you’re employing. When it comes to plates, two factors come into play: plate type (analog, digital or High Definition) and plate line screen/dot percentage. Conventional hexcell anilox can prevent you from taking full advantage of the latest platemaking technologies. However, GTT can help you run finer, stronger, cleaner dots and screens, at lower percentages than ever before. Use the GTT Rangefinder to help choose the ideal GTT size for your particular plate requirements. STEP 3 STICKYBACK TAPE Gone are the days of stickyback guessing games and coping with different grades of tape based on job type. With conventional anilox inking, you typically needed a harder tape for solids, medium for type and combo, and soft for process. But with GTT rolls/sleeves, stickyback is streamlined. In general, a medium- to soft-grade tape is the best first choice because GTT releases ink better with higher densities – yet is also more controlled for fine type or combo/process work. STEP 4 INK Viscosity and pigment load are two prime variables that determine printability. With conventional hexcell anilox technology, density can drop rapidly when viscosity and pigment load are adjusted down. With GTT, depending on your current ink formulation, you may need to lower them both. And while cost savings on ink and faster drying times will likely result, your highest benefit will be increased printability (higher densities at higher speeds with less mottling and pinholing). Many ink manufacturers are now marketing GTT-optimized inks for plug-and-play performance to further streamline your procedures and profitability. STEP 5 PRESSURE When it comes to pressure, everyone agrees that kiss impression on both plate and blade is optimal. But with the realities of conventional hexcell anilox, higher pressure is often required to obtain desired densities and better doctoring especially at faster speeds. However, due to GTT’s inherently superior inkflow qualities, you’ll typically discover that you can back off on the blade pressure and plate pressure to achieve your desired results.
