DPI (Dots Per Inch): A measurement system for determining the resolution of an image. This number refers to the number of physical dots of ink (or, in the case of a computer screen, pixels) that are in one inch of space.

Duotone: Two overlapping halftone screens of different colors that are printed on top of each other. The result is a monochromatic image.

Duplication: The process of transferring original data from a variety of sources onto a Recordable disc to form the microscopic optical marks that contain the digital information. Data can be static or dynamic and unique for each disc copied. Final product is a CD-R or DVD-R.

DVD (Digital Versatile Disc): Optical media disc with a storage capacity of up to 17 gigabytes, depending on the disc’s physical characteristics.

DVD Duplication The process of transferring original data from a variety of sources onto a DVD Recordable disc to form the microscopic optical marks that contain the digital information. Data can be static or dynamic and unique for each disc copied.

DVD Manufacturing Process of copying original data from a master source to a disc by means of “stamping” or “pressing” the digital information, in the form of optical marks called lands and pits, into the raw polycarbonate disc material. The polycarbonate is then metallized to make it reflective producing a DVD-ROM. Data is static information.

DVD Replication Process of copying original data from a master source to a disc by means of “stamping” or “pressing” the digital information, in the form of optical marks called lands and pits, into the raw polycarbonate disc material. The polycarbonate is then metallized to make it reflective producing a DVD-ROM. Data is static information.

DVD-R: Recordable format of DVD that uses dye technology like the CD-R, but can hold more information than a CD-R and requires higher precision “burning” technology for recording. This media is supplementing and replacing DVD-ROM publications.

DVD-ROM: DVD that is manufactured similarly to a CD-ROM, yet can store more information. The ROM is currently the most commonly used form of DVD for distribution of multimedia publications.

Dynamic Information: Digital or graphic data on a disc that can be changed or manipulated for each disc produced.
