I'm using Adobe Illustrator CS5 in combination with Connect You 11. Whenever I export my Illustrator file as a Certified PDF through > File > Export as Certified PDF... the final PDF has been cropped to the width and height of the Artboard (230mm x 300mm). The added bleed (5mm) has been removed.
If I save the same Illustrator file as a PDF ( > File > Save As ) the bleed will remain.
Problem is that most printing offices demand a certified PDF. So I add the bleed to the Artboard (240mm x 310mm), add a layer with crop marks, but then some printers says that the bleed is missing and the artboard has the wrong size.

Thanks in advance!
