When ColorFlow software models the color response of flexographi= c printing with flexo discontinuity, the resulting color response is c= alled a discontinuous color response. ColorFlow software accurately re= presents the flexo discontinuity in both types of a color response: tonal r= esponse and colorimetric response.
The input tint value at which the discontinuity occurs, and the correspo= nding color response of a spot or process ink channel, is called the M= indot of the discontinuous color response. If a discontinuous color re= sponse has tonal and colorimetric components, they have the same Mindot&nbs= p;Tint In value.
Tonal response comprises the EDA of each ink channel whose response is m= easured. If a process or spot ink has a flexo discontinuity, its tonal= response has a step change, at the Mindot Tint In value,&= nbsp;from zero to the EDA value printed by the Mindot. As with continu= ous tonal color responses, the tonal response component of a discontinuous = color response is used for tonal match curve generation, and is reflec= ted in tonal response graphs of devices, device conditions, PCOs, and = SCOs.
Colorimetric response comprises the CIELAB color response of process ink= ramps and overprinted combinations. It also includes the CIELAB color= response of spot ink ramps.
If a process or spot ink has a flexo discontinuity, its colorimetri= c response has a step change at the Mindot Tint In value, = from the substrate color to the color printed by the Mindot. As w= ith continuous tonal color responses, the colorimetric response component o= f a discontinuous color response is used for gray balance curve, devic= e profile, and DeviceLink generation.
