ANSWERS What is GTTTM? Genetic Transfer Technology, or GTT, is the revolutionary product of years of research to engineer the most effective ink- to-plate transfer surface ever. Think of it as the third generation of ink metering technology, succeeding hexcell anilox (standard & elongated) and engraved chrome. Inspired by the super- efficient geometries found in nature, our GTT Open Slalom Ink Channels resemble the helical shape of genetic DNA and harness the power of hydraulic flow. Simply stated, hyper- efficient and consistent ink transfer is built into the very genes of GTT. What are GTT’s three key innovative features? To fully appreciate the differences between conventional anilox and GTT surfaces, consider these three scientific breakthrough features unleashed only in GTT: GEOMETRY GTT’s patented Open Slalom Ink Channel geometry replaces closed-cell geometry which traps ink, and instead employs the efficiency of hydraulic kinetics — freeing your ink to flow calmly and transfer evenly to the plate; COMPOSITION Our new superhard hybrid ceramic layer features the highest density and lowest porosity in the industry for incredible ink release to plate — plus superior longevity, score -resistance and easier cleaning; ENGRAVING Our ConstantBeam laser- engraving process replaces conventional pulsed engraving beams, greatly reducing uneven ceramic roughness and recast. Smooth, hard and precise channel walls emerge which serve to release ink better and extend cylinder life. Why is GTT superior to conventional anilox? Virtually all flexographers today rely on second-generation anilox surfaces made up of closed-cell geometry — basically, holes — into which ink is doctored prior to contact with the printing plate. Problem is, this geometry can create turbulence, foaming and uneven ink release. Results? Mottling, pinholing and haloing among others. GTT’s new Open Slalom Ink Channel geometry instead allows ink to flow calmly and transfer ink precisely – with stunning print results. What’s more, GTT cylinders cover a wider screen range than conventional, meaning you’ll likely require fewer cylinders/ink stations to perform an expanded variety of print jobs. What are GTT “sizes”? Why are there only a few? Now you can stop worrying about the sheer multitude of possible line/volume anilox combinations needed to run your jobs. Since each GTT “size” covers the range of two or more conventional aniloxes, most printers only need two or three GTT “sizes” to perform all printing tasks. So instead of calculating complex BCM/LPI, L/cm and cm3/m2 formulae, just analyse the type of job you’re going to print and select the appropriate GTT size. For example: for extreme opacity, use “XL”; for solid and screen combos, use “L”; midrange and vignette, use “M” or “S”; superfine line/dot work, use “XS.” It’s really that simple. How can GTT benefit me today – and tomorrow? Print more — with less. Turbocharge your presses and realize immediate benefits. In four key categories of commercial printing, GTT outshines conventional engravings: STANDARDIZATION Slash your anilox inventory. How? Because one GTT cylinder often performs the tasks of two – or more – conventional aniloxes; PRINTABILITY Whether solids, screens or linework, GTT can reduce or eliminate mottling, pinholing, haloing and dot gain while delivering stronger and denser solids, crisper and finer type and lines, and extended CMYK color gamut/PantoneTM simulation; DOWNTIME Imagine leaving your cylinders on-press for job after job; imagine using just one ink station for combo jobs; imagine far fewer deep cleanings and slashing makeready; PROFITABILITY Would you like to run your press faster, use fewer rolls per job, spend less on ink, enjoy longer roll/sleeve lifespan? See if GTT can help your bottom line. Will GTT work with my presses, plates and inks? What about “high performance” flexo? Based on tough, real-world shop conditions in over 10,000 installations across the globe, GTT is proven to work with all presses, inks and plates in all facets of flexo. Increasingly, OEMs and printers are demanding GTT for their new presses because of GTT superiority and flexibility. Many older presses spring to life with GTT. In fact, ink manufacturers are developing more cost-effective inks optimized to take advantage of GTT’s ability to run thinner, lower-viscosity inks. GTT is ideally suited to High Performance flexography. How can I decide if GTT is the best solution for me? First, ask yourself if the jobs you run — and those you aspire to run — require the high-quality/high-defintion precision, long-run repeatability, and ink-station reduction that GTT can deliver. Second, consult with an Apex representative who will help you determine whether GTT can meet your goals. If you determine GTT’s benefits exceed your actual needs, Apex offers our world-class conventional anilox cylinder: UltraCell and UltraCellPLUS . Apex pioneered these superfine anilox screens with our UltraMelt laser technology and superhard ceramic. But whether you choose GTT or UltraCell, you can always count on Apex quality, precision and reliability.
