Crop marks
Crop marks are are printed cutting lines on a printed sheet of artwork or completed print job. They are there to indicate where the publication should be trimmed.
CMYK
Cyan, Magenta, Yellow and Black (CMYK) are the four primary printing inks that make up any full color printing job. Also known as the four process colors.
RGB
Red, green and blue are the 3 colors that are used by monitors to display images. They are called additive colors because the more of each of each RGB color that is added, the brighter the resultant color. 100% of RGB will produce white.
Grayscale
A grayscale image (not greyscale) is a digital graphics file made up of 265 levels of gray. Grayscale is the normal method of sending an image to print for black and white images. Photoshop and other digital image editors are able to save files as grayscale, or to convert RGB or CMYK files into grayscale for black and white reproduction.
Die cut
Die cutting is the process whereby shapes are cut out of paper, or other substrates. Designers will generally have to specify a cutting grid, in their page layout or vector drawing program, that the printer will use as a guide for making the Die.
Digital proofing
Digital proofs are produced directly from an output device, as the result of a computer file - as opposed to a photo-mechanical proof.
Laminate
A transparent coating applied to printed sheets to give either a shiny (gloss) or neutral (matt) finish. Usually used on the outer covers of brochures or heavy, single sheet, printed materials. Helps protect the document from moisture and heavy usage, as well as being aesthetically pleasing.
Metallic ink
Ink that contains powdered metal, sometimes with added pigments, to simulate a metallic finish. Gold and silver are the most common, but it is also common to have metallic inks in numerous colors.

Pantones
The proprietary Pantone color matching system is the most popular method of specifying extra colors – not out of the CMYK four color process – for print. Pantone colors are numbered and are made up out of a base set of colors. By specifying a specific Pantone color, a designer knows that there is little chance of color variance on the presses.
Perfect binding
Perfect binding is the process of binding sheets of a document by roughing the edges at the spine and bonding them with glue to an external cover.Paperback books and thick documents, such as brochures and laarger news-stand magazines are generally perfect bound.Thinner publications, such as trade magazines and journals, are generally saddle stitched.
Saddle stitching
A printed document is saddle stitched by stapling its sheets at the fold of the spine, over a mechanical 'saddle'. Saddled stitching is used for thin magazines, brochures and journals. Thicker documents often have to be perfect bound.
Resolution
For the sake of graphics reproduction, the resolution of a bitmap digital graphics image is a measure of its quality, or the amount of digital information it contains. Resolution is measured by the amount of pixels an image contains in height and width.
Vector graphics
A vector is a mathematically calculated method of plotting accurate lines and curves. Unlike bitmap images, it is resolution independent and allows graphics images to be enlarged to any size, without any loss of quality.
Programs such as Adobe Illustrator all use vector graphics formats to save files in, such as .EPS SWF and various CAD file formats.
