Abstract: A profile measuring apparatus is used to detect and record the variations in profile of a substantially planar surface and consists of a frame, front and rear rollers mounted to the frame, a follower rotatably mounted to the frame and extending outwardly between the front and rear rollers so that it may rotate from the frame at least as far as the rollers, a lever rotatably mounted to the frame and responsive to the rotating of the follower, a support mounted to the frame to which the lever is rotatably mounted, and a recording apparatus for measuring the movement of the lever thereby recording the rotation of the follower. The recording apparatus consists of a coiled strip of paper which is uncoiled by rollers which are driven by a sprocket linkage connected to an axle of the front rollers, and a stylus which engages the chart paper and is mounted on an end of the lever such that deflection of the follower causes the stylus to move relative to the coil of chart paper to discribe a trace thereon.

Abstract: A manually portable fluid ink tack tester (10) for sampling and testing the tack of printing inks during press runs has two engaged, rotating rolls (25,26) mounted on parallel axes and in rolling contact on the tester frame (15). One (26) is extended outwardly from the frame (15) to expose the surface of the roll for contacting an ink coated surface and receiving an ink sample therefrom. After receiving the ink, the tester (10) is removed from the ink coated surface and a motor (35) in the tester (10) rotates the rolls (25,26). The force necessary to split the ink between the two rolls (25,26) is measured (13,40) and displayed (13,48), giving an indication of the tack of the ink.
