(v13) Default screen page device keys

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

Four page device keys control the default behavior of screening: DefaultScreenAngle (now obsolete), DefaultScreenAngles (its replacement), DefaultScreenFrequency, and DefaultScreenName. If these keys were not available, it would be necessary to write an Install procedure to set up the default screen, so they provide some automation.

The DefaultScreenAngles page device key also provides a method of specifying whether the default angles should override any other angles set by the job.

For example:

TEXT

            <<
              /DefaultScreenName (Euclidean) cvn
              /DefaultScreenFrequency 56.0
              /DefaultScreenAngles <<
                /Cyan <<
                  /Angle 15.0
                  /Override true
                >>
                /Magenta <<
                  /Angle 75.0
                  /Override true
                >>
                /Yellow <<
                  /Angle 0.0
                  /Override true
                >>
                /Black <<
                  /Angle 45.0
                  /Override true
                >>
                /Default <<
                  /Angle 45.0
                  /Override true
                >>
