Dear
Marco:
I
read your original posting on the ColorSync list, as well as C. David
Tobie's reply, and I just wanted to offer Pantone's perspective on the
issue.
The
PANTONE ColorCue is designed for users to be able to measure a color,
and return the closest PANTONE color to the measured sample. The user
is then able to scroll through the device, and obtain various data,
including CMYK*, RGB and L*a*b* values. However, it is important to
note that the data provided is provided by a lookup table within the
device, and it NOT pure measurement data. As such, it should not be
compared to data that would be provided by a more sophisticated device
that is providing measured values.
*CMYK
values are provided for the PANTONE solid coated library only, as the
data is reflective of the values contained in the current version of
the PANTONE solid to process guide coated.
Further,
we do not recommend use of the PANTONE ColorCue as a strict quality
control tool. Rather, it should be relied upon to provide a 'starting
point' color. Users should always refer back to the printed PANTONE
formula guide to determine the suitability of the color match provided
by the PANTONE ColorCue device.
I
hope this adequately clears up the issue for you. Please do not
hesitate to contact me if you require further assistance.
