3.1 Density reproduction check
REQUIRED TOOLS:
•
Service PC with
path 'GSO library - Hardcopy => General Hardcopy Info => General Services
Info => Application Info => Density Reproduction Check Excel Sheet'
PURPOSE:
With the density reproduction check the difference for a specific film type between
optical density defined in the sensitometric calibration file and the printed optical
density, measured with an external densitometer is checked.
This is a plausibility check for the CDM: In case the measured density values are out
of the specified range, the CDM requires a re-calibration.
This procedure must be carried out with every used film type:
(1) In the browser pages select menu "Service Engineer Tools - Enter Service
Command Session - 3 Print Image - 1 Test Image".
(2) Print out LinCheck.zip and measure the density of the eleven 100 % – 0% fields
with a calibrated MacBeth TR-924, X-Rite 331, 341, X-Rite 301, X-Rite 310 or
Gretag D200-2 densitometer.
(3) To check linearity fill in measured values in the the density reproduction check
Excel file. See Figure 19.
