CDText	Sometimes written as CD-Text, this provides information about the album (disc) and each song track on the disc (see http://en.wikipedia.org/wiki/CD-TEXT ). When inserted in a compatible CD-Player, the information is read and displayed. With in-car systems, the CD-Text information is read and used to transfer the songs onto the vehicles hard disk. When played in a computer, the software can read this information, display it, and use it to look up more information in on-line databases (such as GraceNote).
CMY	Cyan, Magenta, and Yellow are transferred and blended to form the complete set of printable colors on disc.
CMYK	Cyan, Magenta, Yellow, and Black are transferred and blended to form the complete set of printable colors on disc with a deeper black. This is our standard mode of imprinting color discs.
DDP	The Disc Description Protocol (DDP) identifies and describes collections of data that will be recorded onto a compact disc (CD) or digital versatile disc (DVD). DDP allows for automated transfer of data from data publishers (the programs that manipulate content) to disc manufacturers that produce the physical media.
dpi	Dots per inch is often used to give the sense that more is better (see http://en.wikipedia.org/wiki/Dots_per_inch ). The thermal disc imprinters we use are specified as 400 dpi and 290 lpi equivalent. See the dye sublimation information below.
Duplication	Duplication produces finished discs by laser burning the dye coated substrate of CD media blanks. In our process, commercial disc units designed by Teac for volume production are used with robotics to produce fast and reliable production of CD's and DVD's. Depending on the need, discs are duplicated and then imprinted or the order of operations may be reversed. Our duplication process uses the same input file format (DDP) that high volume replicators use for their mastering. We always run in a verify after write mode to verify correct production.
Dye Sublimation	When run in dye sublimation mode, the separate color dots (CMYK) are first vaporized (sublimated), mixed, and then deposited as a single blended color dot rather than 4 separate dots. The result is the same quality and precise colors found in photographic processing.
Genre	Genres are categories or classifications of music which are often arbitrarily assigned (se http://en.wikipedia.org/wiki/Music_genre ). In the context of disc production, CDText has choices for CD-Text genre which are similar, but not identical to the GraceNote genre. GraceNote uses a hierarchy which I list here.
grayscale	This is a low cost capability to print shades of gray using black at full resolution. It achieves photographic quality with quick imprinting times.
lpi	Line per inch is used to describe how the continuous dots in an image are rasterized to print on media. (see http://en.wikipedia.org/wiki/Lines_per_inch ). The disc imprinters we use produce images equivalent to high-end magazine print or traditional photgraphic processes.
Replication	Replication uses a reversed image disc master (similar to a photographic negative) into which molten plastic is pressed to produce a CD or DVD. The media is then trimmed and plated to forma playable CD or DVD (see http://en.wikipedia.org/wiki/CD_replication ). The precise steps required and high cost of set up usually require minimum volume runs of 500 or 1000 discs to be cost effective. Our duplication process uses the same input file format (DDP) that high volume replicators use for their mastering.
