Can anyone tell me if the Paterson Test Strip Printer has a base on which the paper sits onto? If not, then all is good. If so, then I have a couple of further questions. Do you need to remove the easel to use the device, or does it just sit straight onto the surface on which you lay your paper (easel base)? Does it give slightly different exposure results to the full size print, or is the small amount of distance of the paper to lens negligible? Sorry for the silly questions, but I've always just used a piece of board to make strips, but I'd like to speed the process, whilst still giving accurate results.
