USA • The non-profit corporation dedicated to providing flexo press operators and others in the flexo industry hands-on training was honored to take home the Gold award for the College Student Category of Flexographic Technical Association’s 2018 Excellence in Flexography awards.
Student Aaron Pitt (Computype) from Flexographic Tech’s 12-week press operator course produced the award-winning card. The winning holiday card was printed on both sides of 8 pt tag (supplied by Avery Dennison). The black text on the inside of the card was printed in station one and the web was flipped using the turn bar. The student then printed a four-color process image, a spot green, a high gloss spot varnish and a tactile pearlescent varnish over the snowflakes. (The card shows the 4 graduating classes from 2017)
What really sets the card apart is the tactile pearlescent vanish (supplied by Flint Group). The tactile varnish was run using a 105 CPI, 28 BCM anilox roll. With this much ink film thickness, the student had to run slow (95 fmp/29 m/min) with max UV lamp settings in order to cure properly. The card was printed on a Mark Andy 2200 with a printing width of 13” (330 mm) press. The student used extra-wide (half inch) bearer bars on the plate to help reduce the plate bounce. Tight registration on the images with fine detail of logos made registration challenging. High resolution plates (Kodak supplied NX plates) required excellent kiss impression settings to allow for great-looking highlight dots and crisp images.
To ensure the best print quality the students optimized and fingerprinted the press, determined the best anilox rolls, plate screening technology and mounting tape to be used for the different colors. The optimization process allowed the tactile varnish to really pop off the front of the card and provided the touch sensation we were looking for.
