I have two large Xerox printers with 48" wide paper sources.  I need an autocad drawing that has 1/8" crosshatch that will scale to check alignment of my printers. 
  As part of my business, I have ACAD 6 and can print dwg, dxf, tif etc file types.
 
  What is the easiest way to produce a 1/8" crosshatch pattern for checking at B, C or D size drawings.
 
TIA, GWB
