Along with higher speed of the rotary gravure press, evaluation of drying property of prints has become ever more important. The Printing Bureau type gravure printability tester is widely used. On the basis of this tester, we KRK have developed a set-off test method in gravure printing. The tester developed is composed of a drying roller above the impression cylinder to apply a constant load. The drying roller has the same diameter as the impression cylinder, rotating at the same speed and in the same direction. A white paper sheet or film is wound around the drying roller. After a certain span of time following printing, lower the pressurization lever to make the drying roller contact the print. By observing the state of ink transfer onto the white paper or film, the drying property is evaluated.
