Elrepho 3000
MEASURE SAMPLE
OVER STACK
Measurement of a sample over a stack of
sample paper of the same quality, thick
enough to insure no transmission of light
through the stack
MEASURE SAMPLE
OVER WHITE
STANDARD
Measurement of a single sample over the
white calibration standard used to calibrate
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.
