Imagine you have a document in WORD and you want to print it by digital printing. Microsoft says you can't set crop-marks. So you need a work-around. To do this, you increase the paper size by 1 cm all around (A4 now becomes 23 x 31.7 cm). In the header and footer you have blocks that bleed to the edge, so you need to make them larger. It easiest to make them 1 cm large into the edges of the paper. In each corner you exactly place 4 square each with a line weight of 0.5 points. These are now effectively your crop-marks for the printer.I'll call them crop-boxes.

But at the same time you have to indent all your styles by 1 cm to the right to get them in line with the A4 print area. And, you have to check that all your images are still in the right place. It's a palaver. And it's not possible to solve this by importing into Publisher.

However, what happens if you want to print on pre-printed letterhead by digital printing.

I can still be done, but in your header and footer you now have nothing apart from the cropping boxes.

So I thought, why bother to change the original file, simply put crop-boxes in the corners of the A4 sheet, and let the printer line up to these. To make sure you don't print them, simply make them non-printing.

How is my question.

How do you make individual items such as square drawn in WORD non-printing? You only want these not to print, all other drawn items in your document should print normally. Also applies to when you make a pdf from the document. How do you make them non-printing?
