Paper

There are many types of paper available to choose from. This guide cannot begin to cover the scope of the paper selection process. It does however serve as an insight to the papers most commonly used.


Paper Sizes

A job can have any finished size (with ink right up to the edge). With this in mind it’s worth listing the standard A7-A0 sizes. Note the higher the number, the smaller the size.

Size Dimensions (mm)
A7 74 x 105
A6 105 x 148
A5 148 x 210
A4 210 x 297
A3 297 x 420
A2 420 x 594
A1 594 x 840
A0 840 x 1188

The SR prefix is slightly larger than the A series for each size, i.e. SRA2, while the B & C series are larger still.

Our press sizes are as follows:

Press Max Sheet Size (mm)
Heidelberg XL75 750 x 530
HP Indigo 10000 750 x 530
Heidelberg SX52 520 x 370
HP Indigo 5600 330 x 483

Note: max print areas are slightly less than the max sheet sizes, allowing a 10mm minimum border all round, if you require the full size the presses offer.


Types of Paper

Uncoated

This is a paper with a rough uncoated finish. Some examples would be letter paper, copier paper, etc. Uncoated papers are available in most grammages. When printing onto uncoated papers using litho ink, the colours become darker and duller in intensity compared with coated sheets. This is because the ink soaks into the paper, which also slows down drying time. However, when printing digitally using HP Indigo inks, the colours remain bright and print is dry instantly. The Indigo inks do not ‘gloss’ when printing onto uncoated papers, so the effect is still very matt.

Coated

This is the most common paper used for leaflets, brochures and magazines. It is available as a silk (satin) finish or a gloss finish, from 90 gsm through to 400 gsm. Note, silk paper is generally bulkier (thicker) than gloss for the same given weight and both are thinner than the equivalent uncoated.


Paper Weights (grams and microns)

Paper weight is given as the weight in grams per square metre (gsm). A single square sheet (1m x 1m) of copier paper weighs 80g, (not an A4 sheet which will weigh much less) thus in many cases paper weight is directly proportional to paper thickness. With this in mind it is worth noting that some papers, such as the coated papers described above, are usually thinner than the same weight/size sheet of uncoated paper. This is because these papers are denser, e.g. 100gsm coated is thinner than 100gsm uncoated. Sometimes paper is given in thickness as opposed to weight and this is becoming more common. The thickness is given in microns, which are thousandths of a mm.
