Some scanning programs let you do adjustments before the scan actually takes place - this can form a good part of the solution, because you're not forced to start battling with aliasing that's been added by compression/ND routines that the scanner automatically applies.
Other things that might work include making use of calculations in Photoshop. This is good, because it allows you to mix two images based on channel information in a more advanced way to just combining two layers using the standard blend techniques.
For example; using calculations, you can take an image - and apply a blur (or any other filter effect) to only part of an image using a predefined gradient as a mask. Or alternatively, you can use calculations to extract an image from a variable gradient background by combining the two highest contrast channels - this kind of technique could be used to create a good mask for the white paper.
