FLEXO Magazine : June 2013
Good... Better... GTT The Future of Flexo is GTT When Apex launched what could be described as the single most important development in the flexo market since the turn of the century, it was confident that the market would respond positively to its innovative product. This is exactly what happened with the launch of its patented GTT metering rolls in 2008; in the five years since its launch, Apex has sold over 36,000 GTT metering rolls to hundreds of satisfied customers. Genetic Transfer Technology, to give GTT its full name, was Apex’s elegant answer to some of the tradi- tional weaknesses associated with conventional anilox metering, offering new levels of efficiency, quality and cost savings to the entire flexographic printing industry. With GTT, Apex developed an alternative concept to the traditional hexagonal rolls that have been a feature of the anilox market for generations. Its patented slalom structure produces highly consistent inking and a more consistent printing process throughout. While the response to GTT has been overwhelmingly positive from the flexo industry (as evidenced by the numbers of rolls sold since its launch), it is still a relatively new product; hence, there are some customers still using traditional anilox who may require more convincing of its undoubted merits. Consistency & Reproducibility Crucially, however, Apex can confidently state that its GTT engravings are the most consistent and repro- ducible on the market today. It can claim to be the most consistent because GTT has undergone independent testing in some of the most exacting industrial conditions, where the rolls have been found to be the most consistent metering rolls currently on the market. These impressive results came about following analysis of the consistency of GTT engravings by anilox cell measurement specialists Troika. As part of the process, Troika used its industry-leading, Apex-approved AniCAM, the 3D scanning microscope which is a component of Troika’s electronic anilox QC and inventory management system, to measure the engravings on 100 GTT rolls. This high precision, industry-specific tool determined that Apex’s new generation of GTT rolls had tolerances of below 3% across the surface, and from engraving to engraving.
