Print gains length in quark v6

[Milster]

This is weird. I create a document 152x121mm. When I print the document and measure it with a ruler it becomes 153x122mm. Exactly 1mm longer on each side? I don't think that it's a printing glitch, beacause it gains such an exact unit of measure on each side. Must be a setting in Quark somewhere that I can't find that is creating this size gain.
Very confused.
Hope someone has a suggestion
Thanks

Have you set bleed to 1mm?

No - All of my bleed options are greyed-out in the bleed tab of the print dialog box. You can still read them and they are set to zero for all 4 sides. Is there anywhere else bleed can be set?
Thanks blueark
