The Parker Print Surf measures the roughness of a wide variety of samples according to the Dr. John Parker method. With its high speed and pressure setting the Parker Print Surf simulates the way ink is applied during the printing process. The clamp pressure is adjustable making it possible to simulate different printing settings. The instrument is used for fine paper, coated paper, newsprint, coated board, linerboard, films and foils, packaging and carton board. A porosity head is available as an option to test the air permeancy.
