What is: Preflight ?

This is a test in digital pre-press done to analyze or evaluate all the needed components in producing a printing job. It confirms several factors such as the color breaks, the color gamut, the type of disk submitted, and any art which is required (such as reflective photos, illustrations, transparencies, and many others). The preflight also confirms screen fonts, layout files, laser proofs, printer fonts, page sizes, EPS or TIFF files, crop marks, and the print driver.
