Existing Solutions for Scanned Documents
black/white: TIFF G4
Color: JPEG. Randomly used PNG, BMP and other 
raster graphics formats
Often special version formats like „JPEG in TIFF“
Disadvantages:

Several formats already for scanned documents
Even more formats for digital born documents
Loss of information, e.g. with TIFF G4
Bad image quality and huge filesize, e.g. with JPEG
No standardized metadata spread over all formats
No full text searchability (OCR) inside files
Black/White: 
-TIFF FAX G4
Color:
-TIFF
-TIFF LZW
-JPEG
-PDF

Alternative Solution: PDF
Already used widely:
Either to unify file formats
Image2PDF
but also “Office” and other formats
Or to have full text enabled/searchable files
Or to have access to new compression schemes
(e.g. the JPEG2000 file formats family)

Or to harmonize metadata
Conclusion: PDF has none of the disadvantages of 
the legacy formats
“If the decision for PDF as archiving file format is 
made, why not PDF/A –with all its advantages 
over PDF in that application area then?”

e.g. large manuals or multi page construction files
e.g. documents fetched from the archive database 
and send to customers, suppliers, lawyers,…
