I am currently looking at submiting coin images to be considered for use in an upcoming software release. They will only except scans of 2400DPI. This is where I am having a problem. I have tried scanning both at 4800DPI and 19200DPI. When the finaly scan is complete it is only 1200DPI or higher. Any suggestions on how I can get 2400 DPI scans. I have the following scanners the scanner in my Lexmark X6570 printer and a Canon Canoscan 8400F.

Can you just use Photoshop or the gimp to resize/rescale the images?

Hmmm... I have no problem with my HP F380. Maybe it's the program you're opening it with. Maybe it converts it because that's it's limit?

Just an FYI, that's ridiculous. If it's software and the images are meant to be viewed on a monitor they will be viewed at 96 DPI no matter what to 99% of users. If they're meant to be printed, anything over 600 DPI is not discernible to the naked eye.... forget the fact that printers that print that high are rare in the common household.

If it were me, I'd request 600 DPI, but I'd accept 300 DPI, and no one would no the difference unless they looked. I'd also get a lot more images donated which would make my life easier.
