GSM is considered the most reliable metric that determines the thickness and weight of different papers. Calculating the GSM of a paper can enhance your efficiency, no matter whether you are a printer, designer or something else it helps you understand the characteristics of paper.
Importance of GSM
GSM is a unit for measuring the weight of paper in the paper industry. It is the measurement of the density and thickness of a paper. The density of paper affects several printing properties including stiffness, printability, bulk etc. A GSM measures how a paper performs in printing. Hence, GSM is an important parameter for quality control in the paper industry.
However, there are some methods that you should know for calculating the GSM of a paper. These methods are termed streamlined methods for determining GSM.
So, let’s dive into the details of these streamlined methods of calculating GSM.
Precision scale:
It is the most reliable and effective way of determining the GSM of a paper. It is done with the following steps.
Measure the paper dimensions.
Cut the paper into a square Meter.
Now weigh the cut square meter of paper with a GSM balance machine.
The weight obtained now is the GSM of the paper per square meter.
GSM Formula: Grams per square meter (g/m2) = Mass (g) / Area (m2)
Basic Scale method:
A simple method for calculating GSM is also available which is done by following steps.
Take a paper and mention its dimensions.
Cut a square of known size.
By using a GSM round cutter and weighing on the GSM balance machine.
The obtained results should be multiplied by 100.
Calculate the final calculation and this is the GSM of the paper.
However, this method is not as accurate as on a precise scale. Although, it will give you a slight approximation of GSM for several purposes.
By using Online calculators:
The other method of obtaining a GSM is with the help of online calculators which are common nowadays due to the digital era. All you have to do is to just input the weight of the sides of the paper and then it will calculate its GSM.
Benefits of a GSM calculator
GSM refers to grams per square meter. It determines the thickness and density of the paper. If the paper is thicker, its GSM will be higher.
Using a GSM calculator has different benefits. Some of the benefits are listed below.
- Different types of papers can easily be compared.
- The quality of a paper can be determined.
- You can check the quality of a paper to make sure that your printing project will turn out well.
Conclusion
Calculating GSM is essential for those who work for paper products. With the help of streamlined methods, individuals can get information on paper weight in an area, for testing
However, paper manufacturers must calculate the GSM of their paper.
