Corrections made at proofing that are not caused by printer error.

A rendering intent that determines how a file’s color values will be remapped from the current color space into the target color space; in this case any color that is not outside of the target color space (usually that of an output device) is remapped to an exact match; however, out-of-gamut colors are moved to the nearest edge of the target color space, which means they will be clipped. All colors, including white, will be remapped relative to the white point of the current color space.

A binding term for two or more parallel folds that open like an accordion. Brochures and maps often use accordion folds.

Acronym for Address Correction Requested.

Refers to the three primary colors of light; red, green, and blue. They are called “additive” colors because their way of producing color involves light waves that are added together at varying strengths to produce the colors we see on monitors and TVs.

A pixelated or stair-step appearance that can occur when printing a low resolution image (i.e. below 200 pixels per inch) or outputting a file and/or image on a low-resolution device.

A method of screening used in printing whereby tonal values are determined by the size of the of printing dots (“amplitude modulation”); the frequency of the dots does not change. This method of screening is used to produced halftone screens, which consist of a certain number of rows of dots for each color. 

The dot area of a printed halftone, which is measured and defined by a densitometer on a percentage scale of 0 – 100% (solid). The reason it is called “apparent” dot area is due to the measurement corresponding to how the human eye perceives the dot size. Dot area is typically determined by taking a measurement from a screened one-color patch (i.e. 50% cyan) on a press sheet’s color bar. It is a comparative measurement that is derived by comparing a screened patch to its corresponding solid patch (i.e. 50% cyan patch to a solid cyan patch).

Typically accessed via a dialog box within which you configure how the application will carry out its color management capabilities, including its default profiles and color conversion routines. These settings tell the application how you want it to manage color when opening any document as well as importing images and art files into it.

All original copy, including type, photos and illustrations, intended for printing.  

The portion of a lower case letter that extends above the body of the letter; such as b, d, f, etc.

A file encoded in the industry-standard representation for text, ASCII (acronym for American Standard Code for Information Interchange; pronounced “ask-e”). An ASCII file contains only plain text and basic text formatting. The ASCII character set of a microcomputer usually includes 256 characters or control codes. The most consistent ASCII characters are those that can be seen on the keyboard; they fall in the range from ASCII 32 to 127 and are called “plain ASCII.” Any computer can read plain ASCII.

Terminology particular to Adobe applications (InDesign, Photoshop, Illustrator) which refers to applying a profile to a document or imported image. It is possible to assign a profile regardless of whether or not the document or imported image already has a profile associated with it (also referred to as being “tagged” or having an “embedded” profile). 

Terminology particular to Adobe applications (InDesign, Photoshop, Illustrator) which refers to applying a profile to a document or imported image that does not have a profile associated with it (also referred to as being “untagged”). Assuming a profile employs the default profile, as configured in the application’s color settings, as the “source profile” when converting an image or document from one color space to another (i.e RGB to CMYK).

A software that performs the process of scaling Type 1 fonts to the requested size.
