Document Summary
Test #3 blanket, plate and paper caliper test. The scope of this test is measure the thickness of different forms of paper in order to determine a uniform thickness of the paper. This identifies the bulky or dense the paper is and this thickness is measured by a micrometer. Testing caliper is considered a necessity because it affects the flexibility of paper. If a paper is too thick or bulky, a printer could have difficulty printing on that kind of paper. Limitiations on this test cold be human error such as moving the paper while measureing the caliper, broken micrometer and a possible battery drainage witin the micrometer. The test determines the thickness of paper and if the paper does not have a good uniform thickness, this could lead to problems within the printing process. Higher caliper papers hold out better when a there is a heavy ink coverage and do not wrinkle easily.
