(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

                      % The array is the specification in CMYK of the highlight color.

                          } bind
                          /exec load
                        ] cvx
