||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).
||Cyan, Magenta, and Yellow are transferred and blended
to form the complete set of printable colors on disc.
||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.
||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.
||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 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.
||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.
||Genres are categories or classifications of music
which are often arbitrarily assigned (se
). 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
||This is a low cost capability to print shades of gray
using black at full resolution. It achieves photographic quality with
quick imprinting times.
||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 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
). 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.
