I’ve had a head-spinning introduction to the digital printing london business. As one of the newest members of the team, whilst I may be a bit of a digital expert, I’m still learning about Print4UK (and the print industry from scratch). I know we’re commercial printers. I know we’re known for our digital printing in London. But it did get me thinking…. There are all sorts of fascinating things that are going on here. Yet some of the terminology baffled me at first. And I wondered if it might be the same for our clients.

So that’s why I went about doing some research of my own over these first few weeks. I wanted to learn about all the new words I’d been hearing, but I had no idea what they meant. For example, words and phrases like “perfect bound printing”, “prospectus printing” and “short run printing” were just flying straight over my head. Yet these are what we specialise in, here at Print4UK.

And the result is my jargon buster! I hope you’ll find it useful and that it gets you out of that sticky situation where you don’t understand a word or phrase. And, if there are any that I have missed, please let me know because it will help me, as well as plenty of others like you.

Direct Mail – the most common form of direct marketing is direct mail. Direct marketing is a sub-discipline and type of marketing. There are two main definitional characteristics which distinguish it from other types of marketing. The first is that it attempts to send its message directly to consumers, without the use of intervening media. This involves commercial communication with consumers or businesses, usually unsolicited.

This aspect of direct marketing involves an emphasis on trackable, measureable positive responses from consumers regardless of medium.

Dot Gain – this is where the halftone dots of an image print larger than the size they were on the films or printing plates. This results in some loss of detail. Some degree of dot gin is an avoidable part of the printing process and there are settings in several desktop publishing tools to allow for this. Adobe Photoshop has settings to allow for dot gain under its colour setting preferences.

GSM – this stands for grams per square meter and is the standard unit of weight for paper.

Gutter – The inside margins or blank space between two facing pages of a magazine or book is called the gutter. The gutter space is allowed due to the space lost during the binding process, especially during perfect binding. In saddle-stitched publications the gutter is adjusted to allow for a process called ‘creep’, in which the outer pages of a section appear to bunch up and the inner pages protrude more.

This means that if you cut a sheet into halves they will be the same proportion as the original. In other words, a sheet of A3, when cut in half, will give two sheets of A4. There are also B and C size papers and the larger RA and SRA paper sizes, which allow printers to print oversize sheets that can be trimmed to ‘A’ size for commercial use.

In combination with the offset printing technique – offset-litho – this is by far the most popular method of printing for long run non-personalized publications.

Makeready – The combination of activities that comprise the preparation of a printing press to print a job. One of the reasons that a conventional printing job can be so expensive to keep repeating is that the makeready process is very time consuming and, therefore expensive.

Matte Finish – A dull surface.

Microns – The measurement of the thickness of a sheet of paper or board. 1 micron = 0.001mm.

Overall UV Varnish – A high gloss UV varnish which is applied over the entire sheet.

Perfect Binding – A type of unsewn binding where the leaves of the book are held together at the binding edge by adhesive. A cover is then wrapped around and glued on in the spine.

Perforating Creating– A line of punched dots on a printed sheet so that a part of a sheet can be detached by a user at a later date.

Spot Colour – A spot colour is an ‘extra’, or ‘special’ colour that is used in addition to the CMYK four colour process. The extra ink is added to its own roller on the printing press, so as to more accurately print certain colours that are hard to reproduce with CMYK inks. There are a number of companies that manufacture and specify spot colours, most common of these is the Pantone colour matching system. Spot colours are often also used in predominantly black and white publications, where it would be too expensive to add a CMYK graphic element. Advertising is often sold this way and a charge is made for each extra spot colour. It is for these reasons that companies often have several versions of their company logo as part of their corporate identity full colour, mono and a spot colour version.

Spot Gloss UV Varnish – A high gloss varnish which is applied to a specific area of print e.g. a company logo, photograph or document title. Usually used with matt lamination to show greater contrast.

Uncoated paper – Paper that has not been coated with clay to give it a shiny, or ‘coated’ finish.

UV coating – A UV varnish is a shiny coating that is applied to the printed sheet and fixed with an ultraviolet light. It can be used to cover the complete sheet of paper, or just applied to areas of the printed sheet, such as photographs.

Variable Data – Variable-data printing (VDP) (also known as variable-information printing (VIP) or VI) – is a form of on-demand printing in which elements such as text, graphics and images may be changed from one printed piece to the next, without stopping or slowing down the printing process and using information from a database or external file.

WYSIWYG (What You See Is What You Get) (pronounced “wizzywig”) A term used to describe systems that preview full pages on the screen with text and graphics. The final result can vary slightly because of differences in the resolution of the computer screen and the page printer.
