Printing Terminology Explained

Printing is a complex business and it takes a lot of experience to get things right first time. Here are some common terms that may help you.

Here are some well used common print terms

There are two basic methods of modern printing that we use:

Digital and Lithographic.

Digital printing is used for short runs of approximately 500.

Lithographic is a wet ink process that usually applies to print runs of 500 plus.

Terms you may hear:

4:0 or 4:1 or 4:4 etc

Refers to the number of colours used per side. This can be referred to as four back zero / four back one / four back four.

4 Colour Process

Technique of printing that uses the four process colours of ink to simulate colour photographs or illustrations. See CMYK.

4pp

A product that has four pages and usually consists of a sheet folded in half. The 'outside right cover' is the first page, the 'inside' forms pages two and three, and the fourth page is the 'outside left cover'. For instance, an A4 sheet folded in half becomes an A5 4pp brochure.

4pp A4

A product where an A3 sheet is folded in half to create a multi-page A4 product. The first page is the outside right front cover, the second page is the inside left, the third page is the inside right, and the fourth page is the outside left cover. It is also known as double A4.

6pp

A product that has six pages and usually consists of a sheet folded into thirds. Each of the six panels are referred to as pages. For instance, an A4 page folded into three becomes a 6pp DL brochure.

8pp

A product that has eight pages and usually consists of a sheet folded into quarters. Each of the eight panels are referred to as pages. For instance, an over-sized A4 page folded into four becomes an 8pp DL brochure.

Digital Printing

Low cost method of printing best suited for short run jobs. It works directly from electronic data without the need for printing plates. This makes the process very quick but the print quality, although a good alternative is not on par with lithography. Also, you cannot use specific spot colours or metallic inks.

Spine

Back edge of a book

Spiral Bind

A form of binding using a spiral of continuous wire or plastic looped through punched holes in the documents back margin.  This can be either metal or plastic.

Spine

How do I know how wide the spine will be?

There’s a simple formula which determines that width. Just take the number of pages in your book and divide that figure by your text paper’s PPI (Pages Per Inch). Where do you get the PPI?  Let’s say your book has 200 pages and you are printing it on a web press using a paper which has a PPI of 400. Then the width of your book’s spine will be 200 ÷ 400 or half an inch. That’s for a paperback. For a hard cover book, you have to add the thickness of the boards. The easiest way to do this accurately is to have your printer provide you with a template.
