Re: Patone 2.0 and ISO print standards
I searched for PANTONE Goe White Paper on google.com and got:
http://www.pantone.com/downloads/articles/pdfs/GoeWhitePaper.pdf
Well, since it's been in the works for years, maybe that's why Quark 7 and Adobe latest versions all have the capability to use Lab values?
The white paper says:
"The PANTONE Colors in the GoeGuide were designed to be printed
with uniform and industry typical ink film thicknesses. This enables
equal drying times and more control for matching color on press. The
press operator can run at the same ink settings, regardless of color
being printed. As press time is one of the most expensive parts of the
printing process, the time and cost savings attributable to this feature
can be significant."
So, what thicknesses are they using? Guess it doesn't really matter since as Michael has pointed out and Henk has pointed out, that prepress is supposed to get CMYK equivalents (as close as possible) using color management and the CMYK output profile that actually describes the ink/paper combination used. Guess we all should use Relative Colorimetric, the default rendering intent in Adobe and Quark 7? Not documented anywhere. But at least we have not only HTML and sRGB equivalents (for easy picking of PANTONE color equivalents for the web), but also Lab values for easy comparison of what one has printed (on proof, press sheet) to see if it conforms to the PANTONE Lab equivalent. (if you have a spectro, and what about inter-instrument agreement? I'd like to know which spectro PANTONE used)
The Goe paper says:
"Although the new System is designed specifically for spot
color output, Pantone recognizes that users will frequently use
“process” conversions to “match” the spot colors. In cases where
spot colors are used, proofing devices generally must simulate those
colors using the capabilities of inkjet or toner-based printing systems
that have color gamuts that differ from traditional printing presses. In
other cases, the final output may be a digital printing device.
To address these needs of color-managed workflows, PANTONE Goe
uses industry standard L*a*b* color data. This allows software and
output devices to use sophisticated digital color tools including ICC
profiles and color-managed workflows to get the best possible simulation
of a spot color."
