Measuring Paper Samples - Datacolor Elrepho 3000 Manual

MEASURE SAMPLE Measurement of a sample over a stack of
OVER STACK sample paper of the same quality, thick
enough to insure no transmission of light
through the stack
MEASURE SAMPLE Measurement of a single sample over the
OVER WHITE white calibration standard used to calibrate
STANDARD the Elrepho.
If a job's procedure inlcudes a "Print Contrast Task" for coated paper, the
message will instruct to MEASURE PRINTED SAMPLE........ or
MEASURE UNPRINTED SAMPLE...........
There are two methods which will determine the manner in which samples
will be measured.
METHOD 1 Measure a single sample over the black trap, then
over a stack of white sample paper of the same
quality.
METHOD 2 Measure a single sample over the black trap, then
over the white calibration standard used to calibrate
the instrument.
During job setup you can specify which method to use.

Measuring Paper Samples

If METHOD 1 is selected (over black trap and over stack of same quality
paper), and a task required a normal type of measurement, e.g. CIELAB
DATA, that measurement will be assumed to have been made over a stack of
paper and its data will be shared to eliminate one measurement.
Similarly, if METHOD 2 is selected (over black trap and over white
standard), the sample will be assumed to have been measured over the white
tile, therefore, the data will be taken directly from the white calibration
standard currently in use.
