Colour or Black & White scanning – which is best?

Black & White or Full Colour Scanning – which is best?

It used to be that there wasn’t any choice – document scanners only produced black and white images but high end scanners, increased processor speeds and cheaper storage have made full colour scanning a reality. So what are the differences between the two image options?

Image size – A typical A4 sheet scanned in black and white uses about 8k of disk space, the same sheet scanned in full colour will consume about 200k of space. This is because a colour image contains far more information than a black and white image and the latter is fairly easy to compress while a colour image is not. But this apparent disadvantage has disappeared with the advent of much cheaper drives that allow vast amounts of information to be stored on a device that easily fits in your pocket. 

Image detail – Put simply, colour images preserve most of the feel of the original document with changes in ink, notations and highlighting all being perfectly visible…. this is not a trick that black and white scanning can achieve. Indeed some black and white scanners will just lose quite a lot of information that could be vital to someone reviewing the records in the future.

Unfortunately fast colour scanning is still beyond many practices mainly due to the limitations of the equipment being used – quite rightly, not many practices are willing to pay £30,000 for a scanner that will process just one job.

But we are!

Our complete document imaging service makes it easy

We collect your documents free of charge

The scanned images are converted into fully searchable colour PDF files that can be integrated into your existing systems, such as Docman, or simply used as a standalone digital filing system – no extra software required

The scanned files are optionally encrypted and returned to you either on CD or USB stick
