Introduction to Tolerance Sets

Tolerance sets are combinations of one or many colorimetric tolerance types and tolerance values. CAPQ can handle most industry standard tolerance types, such as absolute colour coordinates and colour coordinate differences (Lab, LCh, NCS, etc.), dE (dECMC, dE00 and CIELab dE*) and metamerism index.

A tolerance set can be either local to a colour standard (applies only to that specific standard), or be a global tolerance set (applies to more than one standard).

The tolerances marked as "critical" are the only ones being checked for approval/rejection automatically by CAPQ. This can be useful for example with gloss, where there is a tolerance, but at a certain step in the process it doesn't need to be within tolerances.

Tolerances can have a "warning level". If the warning level is 10% all measurements are rejected if within 10% from the limit.

Only users of the Supervisor role can edit tolerance sets. Only NCS Support can add new global tolerance sets. New local tolerance sets are created by importing a colour standard with set tolerances.
