BENEFITS 4 GTT FOR FLEXIBLE PACKAGING, LABEL AND CORRUGATED BOOST YOUR Profitability GTT‘s potential for overall operational cost reduction is significant. Here’s how: fewer GTT rolls/sleeves are needed to handle more jobs; higher quality product can be delivered with faster turnaround; less ink, plate and tape consumables may be required. Add these results together and see if your margins soar. Our GTT customers worldwide have reported these advantages: GTT CAN BE LIKE ADDING ANOTHER PRESS When you run your presses faster – all the while freeing up ink stations – your net effect is the ability to print more jobs faster with the equipment you already have. SPEND LESS ON INK Your results may vary, but many GTT users describe 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 than conventional anilox. REDUCED SCORING AND BLADE WEAR Because less doctor blade pressure is required and more ink is exposed to the blade resulting in higher lubrication, the risk of scoring is typically reduced. Plus, GTT‘s superhard hybrid ceramic and slalom inkflow geometry combine to resist costly damage. FASTER DRYING TIMES Since you may require less actual ink volume with GTT, ink can dry on your substrate in less time which enables the potential for faster press speeds. CRANK UP THE SPEED How fast can you go? When running conventional anilox at high speeds, ink densities typically drop and increased speed may even result in misting. But thanks to GTT’s improved ink transfer, more impressions per minute are possible while maintaining stronger densities and curtailing misting. LONGER LIFESPAN With the benefits of reduced handling, a super-hard/score- resistant surface and easier cleanup, your GTT cylinder will likely live a longer, healthier life in your pressroom than conventional anilox. CUT OPERATING COSTS AND DOWNTIME Do the math: when you can replace two conventional anilox with just one GTT cylinder to achieve your printing goals, you just saved a lot of time — and money. GTT can help reduce your setup time, cleanup time, plate costs, ink costs, tape costs and blade costs. And reduce your risk of cylinder damage.

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. Because GTT relies on advanced technology to achieve superior performance in printability and potential cost savings with consumables (inks, blades, tapes and plates), printers benefit most when they optimize the five most important production parameters to take advantage of GTT’s power. Our ongoing TechnicalEducation materials enable users to master these five key performance variables to harness the power of GTT surfaces and make high-value adjustments otherwise impossible using conventional anilox surfaces. GTT empowers you to do your very best work every day — and some or all of these five adjustments can help make it happen. STEP 1 GTT SIZE SELECTION Since the GTT series replaces all conventional hexcell anilox screen/volume combinations with just five “sizes” (XS, S, M, L, XL), it is important for printers to choose the correct GTT size based on the type of job to be printed (i.e ., opaque white, combo, vignette, process). Our GTT RangeFinder can guide you toward an appropriate GTT surface for the job you’re printing. When choosing a single GTT cylinder to perform on one ink station the tasks previously managed by two or more conventional anilox 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 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 conventional. Consult with your Apex representative to help choose the ideal GTT size for your particular plate and print job requirements. STEP 3 MOUNTING TAPE With GTT, gone are the days of mounting-tape 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, mounting tape selection is streamlined. In general, only a single hardness grade of tape is required for most jobs because GTT releases ink better with higher densities – yet is also more controlled for fine type or combo/process work. Again, your Apex consultant can advise you based on your flexo speciality. STEP 4 INK In flexography, viscosity and pigment load are two prime variables that can determine printability. With conventional anilox technology, print density drops rapidly when viscosity and pigment load are adjusted down. But with GTT, depending on your current ink formulation, you may benefit by lowering them both. And while cost savings on ink and faster drying times may result, your highest benefit may be increased printability (higher densities at higher speeds with less mottling and pinholing). Adjustments for UV inks should be discussed with your Apex consultant for maximum benefit. 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 anilox, higher pressure is usually required to obtain desired densities and sufficient doctoring (especially at faster speeds.) However, due to GTT’s inherent ink release qualities, you’ll typically discover that you can reduce both blade pressure and plate pressure to achieve your desired results. w ww.byebyeanilox.com | 866-APEX-USA | firstname.lastname@example.org SPINE/BINDINGEDGE APEX Brochure Pages 6-12.indd 5 6/5/12 2:22:40 PM
