Hi, I tried various page margin adjustments with the -m parameter, but ACPU still shrank the chart and always by the same amount....hence my frustration. Actually the problem is a well documented one and is actively being discussed on various forums.

I tried Hi, that's rather a problem, since the sole purpose of Adobe C.P.U. (ACPU) is to print test charts ! Have you tried altering the page margin that printtarg allows, using the -m parameter ? It's possible that ACPU is scaling the test chart to fit it within the printable area (although this would be unhelpful behavior for a test chart print application - it should always crop rather than scale). Perhaps it's worth raising this issue with Adobe on one of their forums, or on the Apple Colorsync list ? Graeme Gill.
