The test charts are in A4 metric size, so you will need to resize them to fit US Letter size stock (I have a perverse sense of pleasure in turning this around, as I am usually forced to deal with US Letter size jobs not fitting A4 stock!).
The zip archive contains two PDF files:
RIP Test Form G+CMYK A4 ai9.pdf = Some elements are specified as grayscale mode (file originally created in Adobe Illustrator 9).
RIP Test Form CMYK A4 CS3.pdf = File saved from Illustrator CS3, with elements converted to CMYK format (there should be no elements defined as "gray").
In addition, I would also make test files that used 100% solid Cyan only covering the entire page and bleeding off all edges...and magenta only, yellow only and black only. I would also try different tints of the primary colours, as well as "gray balance" full sheet tests such as 50c40my etc. You may also wish to test Pantone spot colours too.
Additionally, I would of course also try different images/photos, in full colour, grayscale and "four colour grayscale".
