Printing specialists love to dream up odd and wonderful names for even the most basic print processes. I think it must make them feel important. Anyway, I have started a glossary of printing terms which I’ll update as and when I get inspiration. Let me know if I have missed anything!
Printing the reverse side of a sheet already printed on one side.
Black and White
Originals or reproductions in single colour (black).
Printed area which extends off the trimmed area. It is impossible to print all the way to the fringe of the paper sheet. To accomplish this effect it is necessary to print a bigger area than is necessary and then trim the paper down. Usually a designer would permit an additional 4mm-5mm of bleed to colour and picture areas to permit for a tiny leeway when trimming.
Thick paper over 200gsm in weight, often used for folders, business cards, postcards, brochure covers etc.
Business cards are cards bearing business information about a company or individual. They are shared in the coursework of formal introductions as a convenience and a memory aid. A business card usually includes the giver’s name, company affiliation (usually with a logo) and contact information. Get prices for printed business cards.

The process of using sharp steel rules to cut special shapes, such as the pockets of a folder.
Printing processes in which information is transferred from a computer directly onto paper, without the necessity for film and printing plates.

The most common process for producing full colour print. The three ink colours are Cyan (blue), Magenta (red), Yellow and Black – often often called CMYK. The inks can be overprinted and combined in a variety of different proportions to produce a variety of colours.
Abbreviation for ‘grams per square metre’. This indicates the weight of paper or other stock. For example a typical photocopier paper is 80gsm, a nice letterhead paper might be 120 gsm, a postcard would be about 300gsm. See my article Choosing paper for your print project.

Lithographic Printing (litho)
A standard (non-digital) print process. The process works by first transferring an picture to narrow metal, paper, or plastic printing plates. Rollers apply oil-based ink and water to the plates. Only the inked picture portion is transferred to a rubber blanket that then transfers the picture onto the paper as it passes between it and another cylinder beneath the paper.
Although paper is usually measured in grams per square metre (weight), it is sometimes measured in microns (thickness). A micron is unit of measure equal to one millionth of a metre or .00004″. See my article Choosing paper for your print project.
