If what I provided is not satisfactory,
you might want to try the inverse transformation (in which the values
go in the 'output maximum' field instead of the 'input maximum'
field.).I do think that the inverse transformation is better for
previewing how a given picture will look  on the colored paper than
actually preparing it for print.
