Installing a colourmanagement system
The simplest procedure for installing a CMS involves
simple step-by-step guidance such as that provided by Corel's
CMS 'Wizard'. Prompted by a series of Wizard screens, the
user has only to respond to step-by-step guidance:
Choose one from three alternative colour mapping methods.
(i) Photographic mapping which maintains the
relationship between colours and is recommended for
printing photographs and illustrations with continuous
tone, (ii) Saturation mapping which expands or contracts
the source gamut to fit the destination gamut and is recommended
for printing business graphics, (iii) Automatch,
which automatically detects the type of image to be printed
and selects Photographic or Saturation mapping accordingly.
Choose a scanner profile from a dropdown list to match
the scanner in use. The scanner profile is needed so that
the CMS can measure the variance between the scanner's
output and a set of fixed reference values. This is essentially
software calibration of the device to a standard.
Choose the appropriate monitor manufacturer and model
number from the lists displayed in order to select the correspond
i ng monitor profile.
Finally, choose the appropriate output printing device from
a list displayed to set up the correct printing profile. After
this final choice is made, the CMS proceeds to set up a
system profile based on the choices made.
In circumstances where more than one scanner or more
than one output device is being used, different system profiles
can be created for each combination. The appropriate
profile is then selected at the start of each new project. After
creating a publication using a CMS, original photographs,
proofs and the final printed publication can be used as references
to assess how well the process has worked and to indicate
the need for any further fine tuning. (At each stage of
the process described above, the CMS provides interactive
means of making adjustments to the individual device profiles.)
