Glossary and File Types

AI: Adobe Illustrator files (plural: AIs), The native format of Adobe Illustrator is the AI format (Adobe Illustrator Artwork), a modified version of the older EPS format. The AI format is fairly widely supported, but is less common than the EPS format, and most programs that read AI can also read EPS.

 

CMS: A content management system or CMS is a computer application that allows publishing, editing, modifying, organizing, deleting and maintaining web content from a central interface.

 

Digitize: To convert analog information into digital format for use by a computer.

 

DPI: Dots Per Inch. Number of dots a printer or device (such as a monitor) can display per linear inch.

 

EPS: An EPS, which stands for Encapsulated PostScript can contain text and graphics and is a file type that is theoretically universally recognized by vector graphic applications such Adobe Illustrator and applications used for signage and engraving.

 

JPEG: JPEG, which stands for Joint Photographic Experts Group, the group that established this file standard, is one of the most widely used file formats today. Converting other file formats to JPEG compresses the file, resulting in some loss of visual quality that cannot be restored (referred to as lossy compression).

 

PDF: PDF, which stands for Portable Document Format, is a file encapsulating a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to be displayed. PDFs are often used due to the ability to compress and house large amounts of information, making it easily transferred.

 

Pixel: A pixel (picture element) is the smallest piece of information in an image. It’s one small dot of light among the many dots that make up an image on a computer screen.

 

PPI: Pixels Per Inch or pixel density. The number of pixels per linear inch is used to describe image resolution. A higher PPI means more image detail and correlates to higher image quality.

 

PNG: The PNG (Portable Network Graphics) file format was created as a free, open-source file format. It supports eight-bit images and 24- or 48-bit truecolor. PNG files feature lossless compression and are designed to work well in online viewing applications like web browsers.

 

RAW: Camera RAW formats contain unprocessed data from a digital camera’s sensor. A RAW converter makes precise adjustments before converting to an RGB file format such as TIFF or JPEG for storage, printing, or further manipulation. RAW files do not share a common filename extension, .RAW. These image formats differ according to camera make/model.

 

Resolution: The number of pixels in an image. A higher number correlates to a higher quality image.

 

ServiceNow: ServiceNow is the system used by UAFS to enter requests for on-campus services. 

 

TIFF: Tagged Image File Format is a file format that uses lossless compression that may be edited and resaved without losing image quality. This is a common format for storing images and for file delivery.

 

Vector: Vector graphics can be used in multiple ways but their core usage is for clean-edged graphics, sign making, embroidery, general graphic design (logos/illustration), flat shapes, and animation. Vector graphics are widely used due to their ability to be resized to any size (typically large but to smaller sizes as well) and still retain quality without blurring or losing image quality.
