  The basis weight of the material is among the most fundamental properties of both paper and board. It works as the backbone of the printing industry. In professional printing, GSM or grammage or square meter is an essential factor in determining the quality and performance of printing materials. Comprehending the GSM of the material using a competent grammage tester or a quadrant paper scale , results in exceptional printing and meeting the industry standards.  What is GSM? GSM refers to the paper’s weight per unit area. The higher the paper weight, the heavier the paper is. In fact, when the thickness of the paper increases, the weight itself increases and vice versa.  Paper manufacturers, printers, and research organisations make use of a GSM tester or quadrant paper scale to determine the GSM. First, a specimen of the required size is cut and prepared using a dedicated sample cutter . The cutter is a crucial part of the GSM kit, which ensures the cutting of the rig...

  The calculation of GSM or grammage per square is significant when it comes to measuring the basis weight of a paper or packaging material. To do this, manufacturers either make use of a competent GSM tester or a high-quality quadrant paper scale . Both instruments are crucial for the successful determination of GSM, however, in this blog, we will throw light on the capacities of a quadrant scale. So, let’s go. What is a Quadrant Paper Scale? As the name suggests, a quadrant scale is an instrument that measures the Basis weight of paper, board, or similar materials. The test unit accepts a small test sample to perform the test, prepared using a square paper cutter. On this sample cutter, each specimen is prepared in a given dimension, i.e., 10x10 cm or 20x25 cm.  Once the sample is prepared, it is brought to the scales, which are calibrated to high-accuracy dead weights. The unit maintains this accuracy until the pendulum comes to its original form.  What Factors Mainta...
