Vector Artwork: Artwork that stores mathematical information about
shapes and lines is called vectors. They can be scaled easily without producing
the "stair-step" edges you will see in pixel-based (raster) images. They adapt
to the resolution of any output device and are considered to be resolution
independent. They are produced by programs like Adobe Illustrator®, Macromedia
FreeHand® and CorelDRAW®.

|
Raster Artwork: Artwork and images that are defined by a checkerboard
pattern, similar to viewing mosaic tiles. Raster images are limited by the
number of pixels and cannot be enlarged without producing noticeably jagged,
stair-stepped edges. They are produced by digital cameras, scanners, and can
also be created by programs like Adobe PhotoShop and CorelPHOTO-PAINT (among
others).

Spot Color: Solid, generally flat fields of color. Used for silk
screening where a printer can lay down several solid areas of color to produce
multi-colored artwork; also used to identify additional colors in a four-color
process file or print job.

|
|
Color Space: Refers to the use of color in an imprint or graphic file.
Defined for our purposes as spot color, no color, RGB or CMYK.

|
RGB: Colors defined as a combination of three colors red, green and blue
to produce millions of other colors.
|
|
|
CMYK: Colors defined using a combination of four colors cyan, magenta,
yellow and black to produce millions of other colors; often refered to as
four-color process.
|
|
|
Resolution: The measurement of quality (pixel per inch in file or dots
per inch in output). Low-resolution images may be as low as 72 dpi (or less).
High-resolution images may be as high as 600 dpi (or more).
