Where is the difference between 64gsm paper and 80gsm paper?

Answer:

Usually we say how many grams of this paper means grams, but we all omit the heavy words in the back. In general, the copier uses 70-85gsm of paper, and the printer uses more than 60gsm of paper, too low, it is easier to paper.

GSM means "weight", that is, how many grams per square meter of paper weight. Generally speaking, the higher the weight, the thicker the paper.

The difference between 64gsm paper and 80gsm paper is that the 80gsm paper is thicker than the 64gsm paper.

For example, 60g, 70g, 75g, 85g, 120g and so on, refers to the unit area of paper weight is multiple, because the density of the paper is basically the same, in the unit area, the weight of the paper, the thickness of the paper is thicker. For example, printing machine with general speed is about 40g of the paper, and one machine is used in the 50-60g paper, which is used in 70-85g copier paper, printer with the general minimum do not use less than 60g thick paper, otherwise it is easy to jam.
