	      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);
