I ask the question because apparently the driver software for the large format printers do an amount of interpolation / extrapolation.
So.
If I scan my neg to a specific aspect ratio and scan it to a very high resolution would I then just ask for a series of prints at say 32 inches in the long direction ?
So lets say I have scanned a 4x5 at 4000 dpi. The image is around 21160 x 18100 pixels in size. If I ask for a 32 inch print that would be 21160 / 32 = 661 ppi. Apparently, the software will be set to 720 ppi for the printer and things adjusted accordingly.
This takes the heat out of trying to get a specific image size for all the photos in the project.
I'm finding it difficult to trim my scans to say 21000 x 16800 and the knowledge about the printer drivers may make my efforts obsolete.
Hope I've made myself clear enough ...
Cheers,
