Weight of paper is measured in GSM and correlates to the density of paper in one square meter of area.
Heavier weight photo papers feel heavier to touch, but high weights will not affect the quality of the print itself as much as ink type and receiving layers will.
What type of paper is used for photos?
According to me all papers can be used for printing photos. Like A4 Photo paper, Matte photo paper and glossy photo paper. Most matte papers can be printed on both sides, but glossy paper is usually coated on only one side making comparable double-sided photo printing impossible.
What is the thickness of photo paper?
Photo papers are heavier and thicker than typical multi-purpose papers. This thickness, known as caliper, is necessary to accommodate the greater ink coverage typically found in photos. Typical inkjet paper caliper may be anywhere from a thin 4.3 mil to a thick 10.4 mil paper. Photo paper is usually 7 to 10 mils.
What is GSM in glossy paper?
It is achieved by given the paper the weight per square metre or in short GSM (grams per square metre g/m²) to describe the paper matter density. Common belief is that the heavier the paper is, the better its quality is due to feeling thicker to touch.
What GSM is good quality paper?
Thickness of paper is specified by its weight in grams per square metre (GM or GSM). Low grade photocopier paper is around 80gsm; letterheads 100-120gsm with good quality letterhead around 120gsm. Business cards are around 350gsm and flyers around 300gsm-350gsm.
