3.6.4 Measuring polyester plates
Standard plates and polyester plates are measured with a red LED.
Use of the blue LED or green LED is only recommended when the
coloring of the plate has a strong proportion of light pink hues, as
little image contrast is obtained with red illumination.
Important: Due to the grainy background of polyester plates the repeatability may
be up to +/- 0.8 %. For the same reason and because of the algorithms used for
measuring dots, measurements below 5% or on a 100% patch can sometimes be
incorrect. Therefore, the measuring range for exact readings is limited to 5%
to 99%. Please note that incorrect measurements for 0% or 100% patches do
not indicate that the instrument is functioning poorly. If you were to get incorrect
measurements for 0% or 100% patches, please use the iCPlate2 Target to check
the accuracy of the device (see chapter 2.6.2).
3.6.5 Measuring film
Film should be measured on a professional illumination table in
transmission mode. This is why no choice of illumination is available
for the film setting.
Important: Please make sure that the light table is equipped with a flat and
stable glass.
