Hi there. I have the same problem and after discussion with the sales rep, who communicated with the tech. department, This seems to be a problem only when printing directly from a mac. Further, they instructed me to use the "export PDF" or "Publish" command and use Adobe reader instead of Preview, as they don't "have much control over the pdf generating process"
Maybe it's just me but shouldn't nemetchek take more responsibility for their product compatibility, given they market themselves as a cross-platform software solution...
