Hi Roger, In Section 4.3.1 - Table 1, the standard only refers to curve A for Printing Condition 1 and to curve C for Printing Condition 5 when periodic screening is to be used. The names of the colorants are only mentioned during the definition of the printing sequence. “Equal TVI” is a commonly used term for the current calibration method as opposed to the G7 method. Sometimes we do have to fill in the blanks.

All there "seems" to be are references to the shape of the     curves and the polynomial used to determine the TVIs (shown in Table 9) but     nothing to the effect that there ought to be different aim values for each     process colors? I am tempted to conclude that the specified TVI numbers are     "common" to all four colors? But I hate to come up to that conclusion on my     own.                    Best / Roger Breton         www.graxx.ca          _______________________________________________     Do not post admin requests to the list.
