Pre-Flighting

A process of checking a job for possible problems before the job is sent for final output. This process is used to find problems such as missing fonts, postscript errors and colour problems.

Prepress

The process of getting an image ready to go on press. Digital prepress denotes the entire preparation of a digital file for printing in either a digital or conventional system.

Process Colour

The process colours (Cyan, Magenta, Yellow, and Black) are used in traditional colour printing to reproduce a full colour range.

Proof

A laser printout or as such used to evaluate the typesetting layout and design of a job prior to printing.

Quantity

Confusion can occur when the item can be printed in multiples on one sheet, say 2 or 3 up. If a customer asks for 1000 copies and provides the job 2up the printer will assume 1000 finished items are required and print only 500 sheets. The customer may be disappointed because they meant for 1000 sheets to be run and actually needed 2000. To avoid this confusion quantity always refers to the amount of finished size items required.
