Chris, Lawrence,
Sorry, I disagree.
If "...A red copy would be different from a green copy and may have
differing fields.." then those fields will be visible in monochrome
scans. The colour conveys no essential information - though it does
contribute to ease of use.
The conclusion is surely that colour scanning is only needed if:
* the colour contributes essential information (e.g. some
bar charts, pie charts); or if
* the colour contributes so much to ease of use that the
disadvantages of colour scanning are justified;
(and both of these are rare, for "business documents". There is
(usually) no need to scan in colour to ensure "legal admissibility".
In addition to the file size issue, you need to consider the encoding
and compression scheme. So far as I know, all colour compression
schemes are lossy, whereas monochrome (bi-level) schemes are lossless.
Lossy compression is not the end of the world, but before using it you
need to assure yourself that you will be using a combination of
compression scheme and settings for it that results in only acceptable
losses and that cannot result in any problems (such as the loss of a
small decimal point).

I would have thought the answer is "it depends".
When filling and signing a receipt, these are often multi-coloured with
each element having a differing meaning, eg invoice, customer copy, for
accounts etc. A red copy would be different from a green copy and may
have differing fields.
On the other hand colour may just be used for effect and have no real
meaning other than branding.

Subject: Legal Admissability of Scanned Records
List,
As an adjunct to the ongoing debate on legal admissibility of scanned
records, if a record contains any colour elements, should it be scanned
in colour too? Is a black and white scan admissible? The obvious
implication being an increase in file size.
Regards
Lawrence
