Hi Lynn
I know your question is to Mike but regarding:
As it is I design either the print layout and print it, or the mat and cut it, then physically measure up and input into the opposite required print layout or mat.
Physically measuring may be a source of some of the mis-match errors you are getting.
When working from Qimage and you make your print, why actually measure it. The Page Editor gives you all the numbers you need to within 0.1mm. If you need centre distances than a little arithmetic is required but the end result as far as the numbers are concerned will be more accurate than you measuring.
When you make the mat first, then use the Gunnar software numbers in the Qimage Page Editor.
Another suggestion, if you have standard Qimage templates for your jobs, why not reproduce the equivalent in Corel Draw all ready to import into the Gunner software? Or better still, does the Gunner software have the ability to use templates that can be recalled
I know this does not automate a Gunner set up for you, but making a set of templates for Gunner use will improve that side of the process, just as Qimage templates have helped you with the printing.
