White areas not printing white - suggestions?

Some time ago I scanned a book (it's like a comic/coloring book). I've
since realized I used the wrong settings in the scanner software.

The scanner has a few settings, one is "photo quality" and another is
"color drawing." When I use "color drawing", all white areas on a
page print totally white/blank. But because I scanned using the photo
setting, all white areas print a light grayish mess, made up of all
colors. This of course means every page prints with ink on 100%
coverage of the page.

Does anyone know, is it possible to convert the scanned images with
software, so that the white areas print blank again?

Thanks for reading...

Any image editing program will allow you to adjust the "white point"
of the image. Any image above this level will turn pure white. Even
the image editing program that comes with Windows will do this.
Or you can download the free Picasa from Google or one of the many
free ware or share ware alternatives.

Thanks. I have CorelPHOTO-PAINT, but as yet have not found anything
resembling "white point." I'm also downloading Picasa at the moment
to try that. But if anyone else knows what I mean, any further info
would be appreciated. I could scan the book again, but it has since
been written in. (Gee, I wish scanner software would just let you
import files and convert them. That'd be problem solved.)

They do.
At least you can use Photo image software or OCR software on an existing
image file.

I am not familiar with Corel Photo-Paint, but if you can adjust the
brightness level, you can do the same thing as adjusting the white point. If
there is a histogram adjustment, use that.

It is better to just rescan the book page. (even with the handwriting). Good
Photo editing software allows you to remove the handwriting.
 
The scanner probably has a curves setting that you can adjust the
contrast/exposure of the image. The three scanning progams I'm used to
have it Nikon Scan, Minolta Scan software and Epson scanning software.
In the Epson it is under the professional scanning page. You
essentially have to increase the slope of the curve, to increase
contrast.
To work with the photoeditor you will have to learn the program, there
is probably a book on Photo-Paint available, just check amazon.
