I created the attached PDF file using ConTeXt. As you can see I have a green background, which covers the whole page. However, when I took it to the printer today and he printed two copies for me, there was some white space left at four ends. The amount of space above, below, to the left and to the right was different. Here is my preamble. Can you suggest what I can do so that the whole page has the chosen green background color.
Thanks very much.
