History for managing signatures (history as of 21/02/2011 13:10:34)

Scanned signatures are used in e-Cert to enable signed documents to be produced electronically.  In order to ensure they meet acceptalbe standards for size and quality there is a minimum specification which is accepted by e-Cert.  

e-Cert now contains a signature wizard which can be used to crop and enhance scanned signatures to meet the mimimum acceptable specification, which is: 

-          Microsoft .BMP format
-          Maximum size - half inch high x two inches wide
-          Black and White (1-bit)
-          300 dpi
-          Maximum size 30kb
 
Microsoft .BMP format: When saving the scanned image, choose to save it in this format.
 
Maximum size - half inch high x two inches wide: When you physically sign your specimen signature onto blank paper, ensure that the signature does not exceed this size.   You can then scan the image at full size and crop off any surrounding superfluous image that surrounds the signature (therefore scanning just the signature itself and not the whole page).
 
Black and White (1 bit): This will vary between different scanning applications, but generally you should be looking for the lowest quality scanning option (i.e. text or fax quality, instead of black and white or full colour photo quality).
 
300 dpi:   This will vary between different scanning packages, but generally this option should either be selectable at the time of scanning, or will be set up as the default scanning resolution for the scanner. 
 
Maximum Size 30kb: If all of the above requirements have been fulfilled, then the image should not exceed 30kb in size.
