• Lossless : less compression, large files

• Lossy : high compression, small files


Recommendations

• Make copies and store at more than one location.

• Convert to low resolution, lossy compression for screen viewing.

• Convert to mid resolution, lossless compression for normal printing.


Recommendations

• Strict quality assurance procedures to be implemented like other good production processes.

• Make copies on different media like DAT & CD-ROM.

• Regular Maintenance : Media Transfer every Five years
