(v13) Enabling TrapPro in the Host Renderer

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

When using Sentinel LDK security you can enabled TrapPro with a new product key. A PostScript language configuration file is used to configure the TrapPro parameters. The following is an example:

                        /BlackWidth 1.0
                        /Enabled true
                        /HqnDefaultZone false
                        /HqnObjectToImageRule /Normal
                        /HqnSmallObjectProtectionFactor 0.6
                      %/HqnHighlightTrapColor [ 0.0 1.0 1.0 0 ]
                      % The array is the specification in CMYK of the highlight color.
                        /HqnTextToImageRule (Spread)
                      % or
                      %/HqnTextToImageRule (Normal)
                        /HqnTrapAspectRatio 1.0
                        /HqnTrapFeathering 1
                        /ImageInternalTrapping false
                        /ImageToObjectTrapping true
                      %/ImageTrapPlacement /Center
                      % or
                      %/ImageTrapPlacement /Normal
                        /SlidingTrapLimit 0.9
                        /StepLimit 0.1
                        /TrapColorScaling 1.0
                        /TrapWidth 0.21600001
                      /Trapping /ProcSet findresource /settrapparams get exec
                        /Install [
                          currentpagedevice /Install get /exec load
                            newpath /Trapping /ProcSet findresource /settrapzone get exec
                          } bind
                          /exec load
                        ] cvx
