Linearity Check Of Transfer Image Density - Canon CXDI-31 Service Manual

4.3.12. 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
1) This checking procedure should be performed before the procedure in the section of
"Operation Unit Gamma Correction".
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 SETUP MENU
(3) Rough adjustment
1) Start up the CXDI system.
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.
