Print Inspector

 Baseline Concept

Any measurement or group of measurements can be set as Baseline. 
Note that a selection of patches ONLY is used for this purpose:

  • Substrate
  • Primaries Solids: C, M, Y, K
  • Overprints solids: R, G, B
  • G7® CMY grays: 10, 25, 75 and 100%
  • Primaries Tints: 10, 20 25, 40, 50, 75 and 80%

    No other than listed above patches are taken into account!

A limited number of patches makes results calculated faster and more comparable. 


Baselines - what for?

 There are two important reasons to use baselines:

  1. In normal production sometimes the goal for production is OK-sheet, not a Reference Print Condition! If a customer prefers it we have to respect it.In that case, comparison to the baseline is the most objective way.
  2. We need to track variation in the production - but it can be so that single measurement doesn't contain repetitive patches of the same kind. Calculation of deviations from the baseline corresponds to regular variations and can be used as a substitution.



How does it work?

When you create a Baseline (we recommend to use the group of measurement files instead of single measurement, what can improve accuracy) all new measurements will be calculated automatically, but not already existing.

If you need you can select files for recalculation manually. It is because You may want to keep previously uploaded data calculated to earlier baseline.For each job, you may want to set a new baseline, especially when you mostly print to Ok sheets! In one track, you may have more than one Baseline - but only one is active (default for incoming data). 


Reference Print Condition vs. OK Sheet

ChromaChecker™ system needs to know what is a goal of every job to use correct Aim Values. Unfortunately, most measurement file format doesn't contain that kind of information today. If the main goal is to reprint OK-sheet, nothing is more important that keep all production in stable repeatable conditions. That is what customer expect.

When we want to match color perfectly - we want color managed results then an ICC profile will be the best source of all Aim values for the process control. It is because ICC profile is a description of unique, previously defined Print Conditions. A graphic designer uses ICC Profiles in his workflow and may expect that any color will be reproduced with the colorimetric match.

ChromaChecker™ with Baseline solution brings support for both methods.
