Adobe Illustrator
a popular software program used in the manipulation of electronic files and images, toward the creation of the final artwork.

Banding
In digital printing, this term refers to patterns on a print caused by insufficient color or gray-scale ranges within the output device's image processor, or insufficient information contained within the original scan. Banding is most noticeable in printed areas that fade from light to dark.

Buttfit / Kissfit
the meeting on 2 or more colors where there is no overlap or trap.The result is often a visible thin white line.

CMYK (cyan, magenta, yellow and black)
The four colors in the four-color process. The primary additive colors, red, blue and green, when added together, produce white light. When overlapped, red and blue form magenta, green and red form yellow, and green and blue form cyan. These resulting colors are subtractive and when added together, they produce a dark brown. In order to create an accurate photographic reproduction, the color black must be added.

Color correction: The process of simulating the colors or original shade by using color-management software. Often, an inkjet printer serves as the CMYK output device. This process is important because spot colors cannot be acceptably reproduced with the CMYK color model without making adjustments.

Keylines
rules that are placed in a document to mark specific areas to place graphic images. A keyline can also represent the shape of a three dimensional product while in a flat two dimensional drawing.

Inkjet Printer
A type of printer that sprays tiny streams of quick-drying ink onto the paper. An inkjet printer produces high-quality printing like that of a laser printer.

Overlaminate
A protective clear film that extends an image's outdoor life and enhances its visual quality.

Piezo-electric
An inkjet printing technology that uses a mechanical-electric charge instead of heat to drive microdroplets through the nozzle.

PPI (pixels per inch)
A measurement of resolution. A pixel is a unit of data that should not be confused with dpi (dots per inch) or lpi (lines per inch). If there are more pixels per inch, the image will be sharper

Printer's Spread
Two facing pages in the order they will be printed, e.g. pages 1 and 4 and also 2 and 3 will be printed together for a four-page brochure.

Pixel
The smallest unit of data in a digital image. Together, the small discrete elements constitute an image that can be seen on a monitor or printed on a substrate. A pixel's code contains information relating to color, tone and placement within the larger image.

RGB (red, green, blue)
RGB is an additive color model used in color monitors, conventional photo film and paper to create full color.

PPI (pixels per inch)
A measurement of resolution. A pixel is a unit of data that should not be confused with dpi (dots per inch) or lpi (lines per inch). If there are more pixels per inch, the image will be sharper.

Prepress
Prepress is the process of preparing artwork, film and screens for conventional printing methods.

RIP (raster image processing)
A process using mathematical algorithms to enlarge and print an image. Also, this software often includes "add-on" features, such as color-calibration software, various pattern selections, tools or a print-instruction screen.

Separations
The process of converting an image to CMYK for printing plates,Individual sheets of film or plates. Each sheet of film or plate is for one ink color on press.

UV Inks
Inks that contain pigments or other methods to resist UV fade from direct sunlight and other UV light sources.

UCR
Under Color Removal; done during scanning to reduce the total amount of ink coverage in shadow areas by replacing some of the cyan, magenta and yellow with black. Reductions of ink usage can improve ink drying and dot gain control while on press .

Web Press
High-speed printing press, typically used for high-volume runs, which prints on a continuous roll of paper.
