Thank you to everyone who has provided feedback or suggested improvements. Your ideas have helped us prioritise our work schedule:

1 Increase code efficiency to speed up operation.

2 Develop versions that will make use of the built-in PDF creation routines of OS X for creating compact, low resolution, proof PDFs.

3 Develop a version of Hikona that can be used to output .PS files from Quark documents that have various page sizes. No longer would the page dimensions have to be 'hard-wired' into the script - the script would read the layout dimensions of the Quark document and apply a generic +20mm oversize for crops, bleeds and trims.
