TIFF is right, 200dpi. Yep, I have to load s special set of parameters every time I scan a sheet in. Fortunately I've saved that setting and can call it up easily. I guess it depends on the scanner.

The quality will depend on the size of the sheet in the first place. Those small Hal Leonard fakebook leadsheets don't scan well at all, but I get excellent results from my Warner Brothers fakebooks. I also get great results directkly printing to the MPP program via the Freehand driver from Band In A Box.

It might be worth investing in a program like Finale Songwriter if you need to do good leadsheets with lyrics.
