| Colour Accuracy Issues
CD MANUFACTURING, CD
DUPLICATION
Colour accuracy for CD
duplication can be a big challenge because the colours you
see on your computer monitor can be different than what
actually prints. Unfortunately this isnt uncommon as it has
caused problems for designers regardless of their
experience.
Different
Colour Modes - RGB and 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, its 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.
What can you do? Always
set your design page properties to CMYK before you begin
designing your CD duplication design, and then only work
with CMYK colours.
What You See
On Your Computer Monitor
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
televisions display was slightly different or even a lot
different?
The same holds true for
computer monitors most computer monitors dont 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
design may look different when viewed on different monitors.
What can you do? To
improve the colour accuracy of your computer monitor you can
have it colour calibrated (calibration means having the
monitors 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.
Rich and
Vibrant Colour
All of the colours you
view on your computer monitor are created through the
generation of light, thus youre 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.
What can you do? 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 product
because different printing equipment, calibration, inks and
substrates can produce different results. |
