Printing a Fine Print
RIP Profiling
4. Once the printer has been ink limited and linearized for the new media, and the new
linearization settings have been saved in the media specific 'environment or preset' in the
RIP software, the printer can then be 'profiled' by printing a CMYK profiling test chart.
The resulting CMYK profile therefore describes that 'current state of the printer'. It can
then be used within the print production workflow to ensure accurate and consistent
colour output, either selected in the RIP software and applied to the image data as it is
being rasterized and sent to the printer, or applied to the image files in the image creation
software (eg. Photoshop) before being sent to the RIP.
The above is how a traditional RIP is set up, with many subtle variations depending on
the RIP manufacturer's particular options.
Note that unless the RIP has a spectrophotometer built into it (such as a Fuji Frontier
mini lab) a supported measuring instrument such as a GretagMacbeth EyeOne Pro
Spectrophotometer will be required to linearize and profile the RIP. If the RIP does not
support linearization, then the CMYK profile not only has to describe the printer’s colour
gamut, but also grey balance (linearization) and sometimes also control total ink and
black ink limits. This is not an ideal solution, but can still result in acceptable images.
