### Creating and using a spot color

    <?php
    $ps = ps_new();
    if (!ps_open_file($ps, "spotcolor.ps")) {
      print "Cannot open PostScript file\n";
      exit;
    }

    ps_set_info($ps, "Creator", "spotcolor.php");
    ps_set_info($ps, "Author", "Uwe Steinmann");
    ps_set_info($ps, "Title", "Spot color example");

    ps_begin_page($ps, 596, 842);
    ps_setcolor($ps, "fill", "cmyk", 0.37, 0.0, 0.34, 0.34);
    $spotcolor = ps_makespotcolor($ps, "PANTONE 5565 C", 0);
    ps_setcolor($ps, "fill", "spot", $spotcolor, 0.5, 0.0, 0.0);
    ps_moveto($ps, 100, 100);
    ps_lineto($ps, 100, 200);
    ps_lineto($ps, 200, 200);
    ps_lineto($ps, 200, 100);
    ps_lineto($ps, 100, 100);
    ps_fill($ps);
    ps_end_page($ps);

    ps_delete($ps);
    ?>

This example creates the spot color "PANTONE 5565 C" which is a darker green (olive) and fills a rectangle with 50% intensity.
