PDFs and Bits
Scans to PDF: What Format? If you want to scan to searchable PDFs for document management, don't assume that "scans to PDF format" means "scans to searchable PDF format." Some scanners come with software that scans directly to PDF image format only.Even scanners with spec sheets that say they scan to searchable PDF format don't all scan directly to PDF files in a single step. Make sure that "scans to searchable PDF" means the scanner (or, more precisely, the software it comes with) scans, recognizes text and saves the file, all in one step. 30 Bits (and Up) Claimed color depths over 24 bits are almost always the number of bits the scanner uses to describe color, not the number of different colors the scan element can detect. For most scanners, some of those bits are just noise. Fortunately, almost any scanner offers at least a true 24 bits, which is all you need for anything but transparencies, such as slides or film.
