At Eazy Print, when you mention gsm, we know you’re not talking about the Global System for Mobile Communications. You could be, of course, but our best guess is that you are referring to the thickness of paper. Paper thickness is measured in grams per square metre (gsm).
You will have noticed paper being described as 80gsm, 130gsm or 300gsm. A one square metre sheet of 130gsm paper would weigh…130 grams.
The higher the GSM, the heavier and thicker the paper is going to be. Lighter paper uses less pulp and coating material to make it, so the paper is thinner and has a lower weight.
It’s important to know about paper weight because – armed with this knowledge – you can select the correct product for the job. You will see that a flyer, on 300gsm silk art, is going to be printed on a thick board. A leaflet at 130gsm is going to be on a thinner, lighter paper.
Different types of paper can have very different thicknesses and feel of rigidity, even if they are the same weight. Uncoated paper, for example, is a much thicker and more rigid paper than an equivalent weight of gloss coated art paper.
This difference is due to the way the paper is made. Uncoated paper is made purely from paper pulp with no coating. Paper pulp is much lighter than the material used to create a gloss finish, and so much more pulp is used to create a square metre sheet of uncoated paper - making it thicker and more rigid.
Coated paper, however, has a covering of a clay-like substance applied to the surface of the paper. The process uses much less pulp and a thin layer of coating to make a sheet, so it’s thinner and flimsier.
You can rest assured that Eazy Print is a heavyweight in the industry, offering you a dazzling choice of leaflets and flyers.
