If your 1200dpi B&W is true line art, not greyscale, you should convert to one-bit black and white 
and they should print fine as one color black images. I am assuming they will not be enlarged from 
the scan size, but probably reduced in size, which is OK as long as all the 1200dpi data is in the 
file.  If they are going to be reduced by more than 50% you might think of some reduction in 
greyscale mode before converting to one-bit to keep the DPI around 1200dpi at final size.  Though 
anything from 800-2400dpi will be reasonable.

Are you going to be able to charge him anything for your time in preparing the scans? Of do you feel 
you got that up front as part of your creation fee?

Half of the illustrations were done in pen and ink, and half were painted in full color using acrylics. I scanned each artwork before delivery to the client, to have images to work with in case of loss or damage while the originals were held by the client or the printing company.

Difficulties with the first printer that was contracted to produce the book, and then budget cuts, forced the client to put the book project on hold. The client recently contacted me for assistance in finding alternative means to restart the process of getting the book printed and published.
> One way that I can help is by providing my scans of the artwork. The color scans are 300 ppi CMYK-TIFFs and are color corrected the way I like them. The B/W line drawings are 1200 ppi TIFFs, and I think I made them CMYKs too (I still have to dig out the stored disks). I am particularly concerned about adjusting these B/W scans, as I recall that there are particular steps that ought to be taken to ensure smooth lines without "jaggies" and other issues that arise when preparing scans of line drawings.
