Baselining allows you to set a target based on the condition of the press in what is considered an optimal state. It is usually set in the start to define a target that you can always use as a comparison to the current condition of the press. It is a simple process of selecting the files to be used to define the baseline and select the "Ok/Baseline" button at the bottom of the screen.

 Any measurement or group of measurements can be set as a baseline.  Only the selection of patches are 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%

You will see that ChromaChecker tracks both the result to the target such as GRACoL and to a baseline that is specific to the press. This is different than Benchmarking a press and is intended as a quick way to know if the mechanical aspect of the press has drifted as compared to the workflow or profiling of the press. 


Reference Print Condition vs. OK Sheet

OK Sheets are intended to create a target from a sheet that can be used as a reference target. Baselines are intended to determine the condition of the press from a group of files and become a separate data point shown in the track graphical interface.
