APR
Abbreviation for Automatic Picture Replacement: OPI-alike technology used by Scitex systems. An APR-system can generate low resolution images from large scans or drawings. Users place these lowres images in their lay-out files and will also print using these low res files. This speeds up the handling and printing of images. Once the file commences ripping, the RIP picks up the low res info and then proceeds to locate the corresponding high resolution images in the desired destination.
arabesque
An art element used for ornamentation or decorative effect.
arc lamp
A lamp that produces light by an electrical current arcing across two electrodes. Used as light source in photography and platemaking.
archival storage
The maintenance of a permanent record of images, on a medium such as photographic film, magnetic tape or optical disc. Archival storage is retained until intentionally destroyed, remove or altered.
area mask
An outline mask that isolates a specific area of an image either by shape, color or tone value.
argon laser
A very strong, collimated,directional bluish-colored light that is used to expose images onto orthochromatic or blue sensitive photographic film, paper or printing plates. The spectral output peaks at 470 nanometers. The advantage of an argon laser over a helium neon laser is that the argon laser can image sensitive film,which can be used with a red or yellow safelight. Argon lasers are not used any more.
artifact
A visible defect in an electronic image.

ASIP
Abbreviation for AppleShare Internet Protocol
ascenders
- The lines of lower case type that extended above the body of a letter such as on a “b” or a “d”.
- The parts of lower-case letters “b, d, f, h, k, l,” and “t” that extend above the “x” height (body of a letter).
aspect ratio
The ratio of an object’s height to its width
assembly
Traditionally, the process of attaching film components of pages in their correct positions to a carrier film, goldenrod paper or plastic. A printing plate is exposed using the page imposition. Electronic assembly is the process of placing all pictures, tint blocks, text and line work in their proper location within a digital page file.
asset management
The process of storing, tracking, finding and using digital assets (like images, fonts, documents,..) in a well-organized, efficient manner.
asterisk
![]()
attachment
A data file that is included in an e-mail. There are a lot of e-mail systems that will refuse to forward such attachments if their size exceeds a certain value, typically 2 MB. This keeps a lot of users from using e-mail to exchange prepress files.
ATAPI
Abbreviation for AT Attachment Packet Interface: aspecification that defines the characteristics for an IDE device like a CD-ROM drive. It is essentially an adaptation of the SCSI command set for the IDE interface.
ATM
- Abbreviation for Adobe Type Manager: utility to improve the handling and visual appearance of PostScript Type 1 fonts on Macs and PCs. It will soon not be necessary to install ATM at all: a Type 1 rasterizer is to be part of Mac OS 8.6, and Windows 2000 will also rasterize Type 1 fonts natively. ATM Deluxe remains a rather good utility for managing Type 1 and TrueType fonts, but you have to pay for it.
- Abbreviation for Asynchronous Transfer Mode: high bandwidth, low delay network technology.
autoflow
A page layout program feature that automatically flows text from column to column and page to page.
automatic picture replacement
See APR.
autotrace
A feature in draw programs that automatically traces bitmapped images to create smooth-drawn objects.
