Colour Accuracy
A big graphic design challenge for CD
duplication and DVD duplication is colour accuracy…
the colours you see on your computer monitor can be
different than what actually prints. This isn’t
uncommon and has caused problems for designers
regardless of their experience.
Computer Monitor
Display
Have
you ever gone into an electronics store where they
have a row of televisions on display all lined up
side-by-side, and all displaying the same channel?
Even though they are all displaying the same
channel, did you notice that the colouration of each
television’s display was slightly different… or even
a lot different?
The same holds true for computer monitors – most
computer monitors don’t display true colour. The
result of that means (a) the colouration of your
finished print may look different than what you view
on your computer monitor, and (b) the colour of your
CD duplication or DVD duplication design may look
different when viewed on different monitors.
This can help: To
improve the colour accuracy of your computer monitor
you can have it colour calibrated (“calibration”
means having the monitor’s display optimized for
colour accuracy). Mechanical calibration using a
sensor is a popular way of calibrating a monitor,
but, while calibration can ‘improve’ your colour
display you cannot rely on it to be completely
accurate. You should be able to buy a mechanical
calibration kit from an electronic store that
carries a good range of software titles.
RGB versus CMYK
Computer monitors display imagery in the RGB colour
mode (red, green, blue) yet commercial print is
produced using the CMYK colour mode (cyan, magenta,
yellow, black).
Because RGB has a larger ‘gamut’ (ie: range) of
colours than CMYK, it’s possible to design using RGB
colours that are outside the range of what CMYK can
reproduce. When converting an RGB design to CMYK,
any RGB colours that are outside of the CMYK gamut
will be automatically converted within the CMYK
gamut and the visual result will be a less vibrant
colour.
This can help:
Always set your design page properties to CMYK
before you begin designing your CD duplication or
DVD duplication design, and then only work with CMYK
colours.
Richness Of Colour
All of
the colours you view on your computer monitor are
created through the generation of light, thus you’re
able to achieve very vibrant and rich colours in
your designs. When it comes time to print those
colours, the application of ink onto paper (or
plastic, in the case of the CD or DVD disc) is not
going to be able to produce the same vibrancy and
richness of colour that your monitor was able to
display. The result is typically a flatter or duller
appearance on the finished print than what you
viewed on your monitor.
This can help: If
you have any concerns about colouration of the final
print, hard-copy printed proofs are recommended. It
is important that the hard-copy proofs come from the
same company that will be producing your finished CD
duplication or DVD duplication product because
different printing equipment, calibration, inks and
substrates can produce different results.
