Since there is no coating, this is the most porous paper, which is the best for smudge-less writing with the widest range of pens and pencils when compared to the other finishes. Since there is no coating, there is no glare on the surface, which makes it ideal for prints that have a lot of text or reading materials. Uncoated paper is exactly what it sounds like – paper that has no extra coating or paper finishing. The coating can also be used to adjust the glossiness of the paper according to preference, for example Matte, Silk or Gloss finishes. Generally, this coating will make the paper more receptive to the printing of text and images, so that detail is sharper and colour is brighter and denser. As it does not have a coating it is more absorbent and softer in feel than coated stocks.Ĭoated paper has a surface coating (made from, clay, chalk and latex) that effects the absorbency, smoothness, gloss and weight of the paper. Uncoated paper is paper that has been made without a surface costing. Types of Stock: What is the difference between coated and uncoated paper? In the UK we just refer to metric measurements, if you start dealing with the US they are still all imperial. These days you can get digital callipers that will measure the thickness of a sheet in mm starting from as thin as 0.01mm The measurement is taken with a micrometer which can also be called a calliper. The calliper is the thickness of a sheet of paper.
Note that whilst grammage (GSM) is used to describe the thickness of the sheet it is actually the weight of one square meter of the substrate. This is the common measurement for paper used in the UK and Europe.
GSM stands for grams per square meter – this is the metric used to describe the thickness of the paper. The paper weight is a guide to how thick the sheet will be, the heavier the paper weight, generally the thicker the sheet is, but the true thickness will depend on how dense the fibres are compressed in the sheet. Generally, there are two types of stock – coated and uncoated. Printing paper is also known as stock or substrate.
