FLEXO Magazine : January 2010
40 FLEXO JANUARY 2010 www.flexography.org • WKA examined the advantages of sleeve lasering using high-resolution optics, which offers plates at up to 4,000dpi resolution. • The laser point, which draws the pixels, is 6.35μ. • The test results were unequivocal, and it was only a short time before all imagers in the sleeves manu- facturing unit were equipped with the high-resolution option. FLEXIBLE PACKAGING Warburger Klischeeanstalt (WKA), located in Warburg on the northern border of Waldeckerland, Germany, is an active member of the DFTA and one of the most renowned European companies in flexible packaging. The company offers a wide range of packaging supply chain services, from the first sketched idea through to ready-to- print, flexo-printing plates for packaging. WKA's success can be attributed to its dynamic founder and, chief executive Udo Linke, his committed team of 150 employees and a first-class technical infrastructure. Linke was the first entrepreneur to put the idea of a flexible round plate---flexo-printing plates in the form of digitally man- ufactured sleeves---into practice. Doing so made WKA the largest European supplier of digitally manufactured printing plates for flexible packaging. Since 1996, the company has acquired experience in the laser-supported manufacturing of digital flexo-printing plates, and has the enormous potential to manufacture 45,000 round plates per year for flexo printing. But, while WKA may be considered a pioneer in high-quality laser printing plates, the company has not rested on its laurels. It is currently working on developing and implement- ing innovative new processes and technologies that will allow printers to derive even more advantages from in-the-round flexo plates. BEST CHOICE 4,000 WKA's work involves continually researching which sleeve materials, printing screen technologies and imaging resolu- tions in prepress and laser manufacturing can help improve in-the-round plates for flexo. The company 's Best Choice 4,000 project entailed taking a close look at the advantages of sleeve lasering. This was achieved using laser imager high- A Better Image WKA Boosts Quality of Flexo Sleeves with New, High-Resolution Technology By Ian Hole Udo Linke (left), Dr. Thomas Klein (center) and Volker Klos discuss how their print quality has improved with the new imager.
