(v13) HqnImpose2 prefixes

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

Any defined Prefix is called before the /Objective procedure. They are expected to be used most often for device-specific operations. This might include dynamic alteration of gutter sizes based on the page size that has been requested (for example, because gutters must be reduced in order to fit two Letter pages onto a film, whereas you prefer a larger gutter when using A4). You can also use a prefix to turn crop marks on or off, depending on whether the sending application had included crop mark information (as detected by whether the page size matches A4 or A4Extra, and so on).

As with objectives and tactics the value of /Prefix should be either a key referring to an existing procedure, or a PostScript-language procedure.

These are the pre-defined prefixes included in the procset:
