■IMAGE SCALE
Set the reduction mode to reduce binary image data. This setting is
performed on the third hierarchy.
<Parameter (choice input method)> : Default value
LINE DRAW. MODE Lines are ensured when binary image data is reduced.
PICTURE MODE Density is ensured when binary image data is reduced.
(Lines are simply thinned out.)
■SCREENING (HP-GL, DSCAN, TIFF only)
Specifies the multi-valued image data screening method.
This setting is performed on the third hierarchy.
<Parameter (choice input method)> : Default value
LINE DRAW. MODE Screening appropriate to line drawing is performed for
multi-valued image data.
GRAPHICS MODE Screening appropriate to computer graphics is
performed for the multi-valued image data.
PICTURE MODE Screening appropriate to pictures is performed for the
multi-valued image data. This mode requires a little
more time than the GRAPHIC and PICTURE MODEs
for the treatment.
