Digital imaging was investigated as a potential means of processing high de
nsity dot arrays for analytical purposes. Using a high resolution digital c
amera, a colour image of the dot array was taken and subsequently processed
using in-house developed National Instruments LabVIEW(R) software to retur
n numerical values for the red, green and blue components of the colour of
each dot. (C) 2000 Elsevier Science B.V. All rights reserved.
