The concept of a rule-based variable is to build a variable that will change based on the state of another setting. For example:
IF job type is Digital, THEN change "Image Resolution" check to 150ppi
ELSE
IF job type is Offset THEN change "Image Resolution" check to 300ppi
OR IF Paper Stock is Uncoated
AND Printing Method is Sheetfed THEN Total Ink Coverage value is 320%
ELSE IF Paper Stock is Coated AND Printing Method is Sheetfed THEN Total Ink Coverage value is 300%
Rule based variables have two parts, one of the variable(s) used to trigger the Rule, and the other is the variable with the conditions defined.
As defined in the example above, the two triggers are “Digital” or “Offset” and the conditional variables are “150” and “300”.
To make the Rule Based Variable work you will need to create two variables. One will be a any variable and the other will be the actual “Rule Based” variable.
Following is a step-by-step explanation of how a rule-based variable is defined and applied to a preflight profile.
This example is based on the following rule:
IF job type is Digital THEN change "Image Resolution" check to 150ppi. AND IF job type is Offset then change "Image Resolution" to 300ppi.
