INT-FB 2 Set multi tone ctrl(light) feedback rate
Detail To set the extent of the gradation correction result of real-time multiple tone control (light) to be
reflected to LUT in percentage.
If the value is large, gradation will be closer to the target value with a single execution of the control.
However, the hue may be changed dramatically before and after the execution. Decrease the value
when prioritizing hue continuity. Degree of correction by the control will be small.
Use Case When hue variation occurs
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Display/Adj/Set Range 0 to 100

PTN-INT 2 Set of multi tone control patch pattern
Detail To set the patch patter formed by real-time multiple tone control (light).
When 0 is set, 1-gradation patches are formed by each dithering method (error diffusion/low screen
ruling/high screen ruling) for each color (Y/M/C/Bk).
When 1 is set, 3-gradation patches are formed by low screen ruling dithering method for each color
(Y/M/C/Bk). In this case, the gradation correction result is reflected to other dithering methods at
the rate set in DITH-FB.
Use Case When hue variation occurs
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Display/Adj/Set Range 0 to 1
0: Patch pattern 1, 1: Patch pattern 2
Default Value 0

INTPPR-1 2 Set multi tone control (light) exe intvl
Detail To set the number of sheets as the intervals to execute real-time multiple tone control (light).
When the number of sheets reaches the specified value, the control is executed by interrupting an
ongoing job. After starting a job, however, it is not executed until the number of sheets reaches
the value set in INTPPR-2.
Increase the value when prioritizing productivity over image quality, and decrease the value when
the density varies dramatically.
Use Case - When the density varies dramatically
- Upon user's request (to improve productivity)
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Caution If the value is too large, the density of image becomes different before and after the interruption.
If the value is too small, productivity is decreased.
Display/Adj/Set Range 5 to 1000
