Match Function (528, 530 only)
The Match function is used to quickly find the best color
match to a measured color from a database of references. Up
to 16 matches are displays based on Delta-E difference. The
instrument can store over 1,400 references across a total of 10
groups. When used in conjunction with X-Rite’s ColorMail
Express (CMX), color libraries, such as a PANTONE®
database can easily be downloaded to the instrument and used
for reference matches. Reference databases can also be
uploaded to a computer using CMX (530 instrument only).
You should set the Match Options before taking any
measurements.
