 * Color space for crop marks:

 * Create crop marks which will be visible on all color separations, using the

 * special color "All".

 *

 * Create a CMYK document by loading a CMYK image and create the special

 * color "All". Draw some crop marks with standard vector graphics and

 * output some info text outside of the actual page area (i.e. outside

 * of the CropBox).

 *

 * Test in Acrobat X/XI:

 * Show the MediaBox with Tools, Print Production, More Production,

 * Set Page Boxes, Set to Zero.

 * Choose Tools, Print Production, Output Preview:

 * All elements with color "All" will be visible in all combinations of

 * separation previews.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 9

 * Required data: CMYK image
