Notes:
• A PostScript job can override the effect of Screening by using sethalftone ,
setscreen , or setcolorscreen operators, unless Screening is set to IET or
IETPictureGrade.
• A PostScript job can enter or exit IET or PictureGrade using the Screening
parameter in a setpagedevice call. This does not change the user default
printer settings for print quality, which are read and used by the interpreter for
the next print job unless the setpagedevice is issued in a startjob context.
