G7 Colorspace tolerance value question

  • 1.  G7 Colorspace tolerance value question

    Posted 14 days ago
    ​Hello all,

    A customer has asked me earlier today a question relative to the upcoming G7 Colorspace requirements tolerances.

    He pointed me to a video:
    https://www.idealliance.org/idealliance-video-library-g7-master-pass-fail-tolerances

    where it is specifically mentioned that the Max CIEDE2000 error for proofs is 5.5 and that this will take effect in October 2019.

    Looking for additional information I found the April 2019 requirements (G7_Master_PassFail_v353.pdf) where, on page 9, it is specifically written that this tolerance will change from 5.5. to 4.0 in October 2019.

    What is the correct answer?

    It is my understanding that the max error is a new tolerance for the Colorspace requirements, so was 5.5 used for development and 4.0 to be used as the "released" value?

    Thanks!

    Hello Danny,

    The New G7 Master Pass/Fail Tolerances published in April's version 35 went into effect May 1, 2019 (including 5.5 Max dE00 for Proof-Colorspace).

    These will again be narrowed 6 months later in October 2019 with the tighter Max dE00 Proof-Colorspace tolerance of 4.0.

    A one year grace period for these new sets of tolerances will be in effect for G7 Master Qualification to allow for global print services providers, OEMs, and others to implement and adjust accordingly so please do not hesitate to contact us with any questions.

    Thank you!

    Hello all, will there be a new update to Curve 4 that will automatically have the new tolerances?

    Thanks, Den

    I've been in touch with Chromix (the publisher of Curve4), and the answer is yes, there will be an update. I was told it might be several weeks.
