Opacity Measurement - Konica Minolta CM-23d Instruction Manual

„ Opacity Measurement
The transparency and opacity of paper are displayed as numerical values.
If the specimen is opaque, the value is determined only by the brightness of the specimen with no influence from
the background, so the value for a white background will be the same as for a black background, and the opacity
value (OP value) will be 100%.
Memo
Manual averaging cannot be used in Opacity mode, and the measurement conditions are only SCI or SCE. SCI+SCE
cannot be selected.
Notes
To measure in Opacity mode, the target must also be measured in Opacity mode. In addition, when measuring
according to a specific international standard, the visual field and the light source must also be set according
to the standard.
