ABSTRACT:
An improved testing apparatus for examining printing materials. The testing apparatus is comprised of a rotatable sector that is rotated at selected, controlled speeds. At least one rotatable printing disk, mounted adjacent to the sector, is moved by fluid drive means into and out of contact with a test strip mounted on the sector. The pressure with which the disk is applied to the sector is continuously monitored and held constant to maintain the printing pressure at the desired level. A programmable controller controls the speed and position of the sector and the movement and contact pressure of the disk relative to the sector.
