(11) Linearity Check of Transfer Image Density
1) Purpose
An SMPTE image is used to check whether the density linearity of the image printed
out by the printer and the image displayed on the high-definition monitor matches the
density linearity of the image transferred by the CXDI.
2) Notes
2-1) This checking procedure should be performed before the procedure in the section of
“Operation Unit Gamma Correction”.
2-2) The adjustment and checking procedures below should be completed before
performing this procedure.
A) The printer and high-definition monitor connections and setting adjustments
should be completed. The printer and monitor image output settings should be set
to LINEAR.
For example, if the KODAK MLP190 is connected, the printer parameter
“-S configuration” must be set to “-S CS000”. For other printers, refer to
“Printers and Parameter Examples Reference” in “Network Connections”, and set
so that the curve shape is 0 (density linear).
B) Be sure to calibrate the printer and high-definition monitor units separately before
performing this procedure.
C) When the imaging screen is “tray type”, change it to “category type” by selecting:
System Æ SETUP MENU Æ CUSTOMIZE DISPLAY.
3) Rough adjustment
3-1) Start up the CXDI system.
3-2) Using the two knobs at the rear of the operation unit, adjust the brightness and
contrast of the touch panel screen for optimum visibility.
3-3) On the exposure screen, select the exposure mode “SMPTE” and wait until “READY”
appears. [Fig. 1]
