/FAQ
BLEED:
the area directly outside the edge of your cd cover. Please
include an extra 3mm of colour around the outside edge, so
that if the inserts are cut less than perfectly (never, ever
happens!) you won’t see an unsightly white sliver along the
edge.
ENHANCED
CD: any content you add to a music CD beyond the
actual music tracks. Video footage, photos, lyrics, or even a
weblink can be added without increasing the unit cost of
yours disc. each disc holds 650 MB worth of data, why not use
that extra space to promote yourself.
GLASS
MASTER: is the process used to make a stamper for
pressing discs. This can only be done by the manufacturing
plant. Your CDR master will never be a glass master no matter
how shiny it is.
HALFTONE:
is the transformation of a greyscale or colour image to a
pattern of small dots with a limited number of colours (e.g.
just black dots on white background), in order to make it
printable.
LINE
ART: is any image that consists of distinct straight
and curved lines placed against a (usually plain) background,
without gradations in (darkness) or to represent
two-dimensional or three-dimensional objects. Line art can
use lines of different colors, although line art is usually
monochromatic. Adobe Illustrator, is one of the most common
vector art, or line art design programs on the market.
MIRROR
BAND: the surface of a CD changes toward the center.
at 38mm the aluminum, or silver transitions to a mirror and
then to clear plastic at 36mm. It’s important to consider how
your label design will be affected by this change. Often a
solid coat of white ink applied first will soften, or wipe
out any colour difference.
PMS or SPOT
COLOUR: is a term common to the printing industry.
Most full colour printing uses process or CMYK colour to
achieve a full colour effect. Your CD inserts will be printed
this way. Spot colour involves using an exact ‘recipe’ to
make a specific hue ie. PMS 280 BLUE. The Pantone Matching
System is used internationally to ensure colour consistency.
We can add a spot colour to your CMYK project, but the cost
is higher and the turn time may increase by a few days.
RED BOOK
AUDIO: is the standard for audio cd‘s (Compact Disc
Digital Audio system, or CDDA). It is named after one of a
set of books that contain the technical specifications for
all CD and CDrom formatted discs.The first edition of the Red
Book was released in June, 1980 by Philips and Sony. The Red
Book specifies the physical parameters and properties of the
CD, the optical "stylus" parameters, deviations and error
rate, and subcode channels and graphics. It also specifies
the form of digital audio encoding (2-channel,16-bit sampled
at 44100 Bit rate = 44100 samples/s ? 16 bit/sample ? 2
channels = 1411.2 kbit/s (more than 10 MB per minute) Blah,
blah, blah...
REGISTRATION
MARKS: Since your color document is separated into
FOUR-color plates (CMYK) when it is “ripped” by the Raster
Image Processor (get it – "RIP"ed) the printer needs to
precisely align these plates on the press to successfully
print the job. You’ve likey seen newspaper cartoons with the
colors spilling out of the lines - this is an example of
registration gone bad or a sloppy cartoonist, or both. By
creating REGISTRATION MARKS, the printer is able to align the
colors precisely on top of each other and create a perfect
colour blend. In the age of digital printing, these processes
are highly automated, but the potential for disaster still
exists.
TRAPPING:
is used to overlap the pantone colours on your label art, and
avoid the problems that result should MISREGISTRATION occur
in the silk-screening process. If you’ve ever seen a colour
newspaper image printed out of registration, you can
understand that minimizing the effect is critical. Unless
you're skilled and experienced at trapping your artwork, it's
probably best to leave the trapping to us. Trapping is a
service we provide for free, and we have highly skilled and
overpaid professionals to ensure that your job is trapped
correctly.
TRAYCARD:
the ‘other’ piece of printing that fits into a standard jewel
box. The back of your CD is often where you’d place a track
listing, and contact information. The spines which show when
your CD is on edge, are attached to the traycard. These can
be printed on one side only, or on both sides when a clear
tray is used to hold your disc.
