It also does not sound like they have much experience scanning old printed materials either. There are many little issues that can come up with graphics and text during scanning that can only be corrected by rescanning a page. For example, if a graphic has a mosaic pattern in it having the page slightly askew when scanned can result in artificial artifacts especially when scanning at 300 DPI. Scanning at a higher resolution, 600+ DPI, then downsampling after clean up can avoid issues with graphics. The RGB to CMYK is true as well. Scanning black and white pages then converting to CMYK can result in black colors that are not rich and/or do not match the touch up colors.
