color/colorAll_for_cropmarks

 * 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" with make_spotcolor(). 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 7 or 8:

 * Show the MediaBox with Document, Crop Pages, Set to Zero.

 * Choose Advanced, (Print Production), Output Preview:

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

 * separation previews.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 7

 * Required data: CMYK image
