Hi. my Adobe reader could not open pdf file which is created by PosteRazor and says "An error exists on this page.Acrobat may not display the page correctly..." i use PosteRazor v 1.5.2 and Adobe reader 9.3.4.i attached the pdf.
Sorry for this extremely late answer. The PDF does indeed look wrong.
Just in case if you can remember the details, was the loaded image displayed correctly in PosteRazor? And do you still have the original image? I am interested in knowing what the format/colorspace/bitdepth of the image were.
PosteRazor 1.9.5 has a few improvements with 16-bit and cmyk images. It may already work better for your use case.
I get an error "insuffcicient data for image" when posterazor starts Adobe reader 9.3
