Uncoated stock is more porous, and therefore more absorbent of inks, which means that any images printed onto the paper will appear duller, because the paper will soak up more ink. As it is uncoated, the texture of the stock is rougher.
Uncoated paper is available in many different print finishes, colours and weights. Premium quality uncoated is used for business stationery, and commonly used in laser printers.
To create coated paper, uncoated stock is buffed and polished in polished chrome cylinders. The stock is less porous and absorbent, so printed images appear glossier and of a higher quality, because of the oils in the ink and the fact that the inks do not get absorbed by the paper.
Images, type and photographs are sharper on coated stock.
Coated papers are available in a gloss, silk and matt finish, which is why it is often referred to as art paper.
It is used to print brochures, leaflets and posters, and a wide range of design for print formats, particularly high volume print runs.
Wove paper is premium quality paper made on a closely woven wire roller and has a faint mesh pattern. It is a popular sheet for stationery and book publishing. It has a uniform surface without a texture.
Laid paper is a premium quality paper with a textured pattern of parallel lines, similar to hand made paper. It is commonly used for business stationery.
Bond is an economic wove paper, often used for copying or laser printers. A higher quality bond stock can be used for letterheads.
Paper weight
(GSM = Grams per square metre)
90-100gsm - Used for stationery, text for magazines and booklets, flyers and brochures.
120-170gsm - Used for text for booklets, flyers and brochures (the heavier the weight, the more upmarket the feel)
200-250gsm - Magazine and booklet covers
280-420gsm - Used for cards, book and booklet covers
Thicker paper is more durable because it is denser, but it's also mainly more expensive
Paper Sizes
In commercial printing SRA paper is often used. SRA paper is slightly larger than the A series to provide room for grip, trim and bleed. These are untrimmed raw papers. RA stands for 'raw format A'
After being printed and bound, the paper sheets will be cut to match the A format.
A0 - 841mm x 1189mm / SRA0 - 900 x 1280mm
A1 - 594 x 841mm / SRA1 - 640 x 900mm
A2 - 420 x 594mm / SRA2 - 450 - 640mm
A3 - 297 x 420mm / SRA3 - 320 x 450mm
A4 - 210 x 297mm / SRA4 - 225 x 320mm
A5 - 148 x 210mm
A6 - 105 x 148mm
