Dov Isaacs, when using the export feature, i'm using the preset 'Press Quality' profile in InDesign 6.0
I'll try the Standard you're suggesting, to see if it makes any difference. Though in this test (export vs print to pdf), no standards were used in neither of the two PDF's, so i don't think that's the reason.
Im printing the PDF's from Acrobat Pro (newest version).
I'll try and provide som actual pictures of the problem that's occuring, along with the two PDF's later today
