Document Summary
The purpose of this instrumentation test is to calculate the nominal basis weight and compare it to the actual basis weight, as well as the nominal grammage and the actual grammage. The conditions for this experiment were that each of the five different paper samples-two coated, two uncoated, and one newsprint were to be stacked in sets of ten, cut into 5 x5 squares and weighed using the scale. This test is important, as the weight of the paper must be known in order to properly set up a press for a job during the makeready stage of production. It is also important information for ordering paper, as the paper must be suitable for a specific job. Procedure: select 2 uncoated, 2 coated, and 1-newsprint paper samples, cut paper using the paper cutter into 5 x5 squares, you will need 10 squares for this test. Individually weigh each of the samples on a scale, record your results.
