Calcheck Chart
The Calcheck Chart data type is where charts are configured and stored for use in colour validation checks.
The charts are comprised of user-­‐created or imported colour patches, along with target standards and tolerances.
These items are saved to the database and can be used and/or adjusted at any time. The Calcheck Chart is then assigned
to a Press and used in conjunction with the Displays
application to provide a validation check for a softproofing
monitor.
Once the chart is setup, it normally requires no further
changes; the standards to be used are saved with the chart.
The window shows a list of the patches on the right and
colour information on the left. For each patch selected its Lab
values, delta tolerance and patch type can be adjusted. The
overall target preferences are specified in the lower half of
the left panel.
Toolbar Options

default* values. Values and colour names can be adjusted as desired.

*Note: When creating or importing new colours, they are stored with the default tolerance settings. This is user

Patch Definition
On the left are a series of controls used to define each patch. Selecting a patch from the list
will load the colour into the colour match box at the top and load the Lab/CMYK values into
the respective fields. To change the value, simply type the new number into the relevant
field.
