specified on printer1, while all the odd-numbered pages should match the halftone configuration specified on printer2. Figure 18 on page 179 provides an example of a monochrome RIP daemon configuration file, with the variables changed from the Color daemon configuration file in bold-face type. Hierarchy of transform options InfoPrint assigns a hierarchy to its use of flags and configuration-file information when it runs the PDF transform program. The following lists the order in which InfoPrint uses flags and information specified in configuration files: 1. Any values you specify on the command line, including values in the configuration file you specify with the -C flag. InfoPrint commands process flags from left to right. If you enter the same flag more than once, InfoPrint uses the last occurrence of the flag to determine the value to use. For example, if you specify this command: pdfprs -C8263.cfg -r240 -r300 myfile.ps The pdfprs command transforms the file using 300-pel resolution. InfoPrint ignores the resolution value specified in the configuration file 8263.cfg and the first -r240 flag and value. 2. Values specified in the default transform command configuration file named in Table 24 on page 177. 3. Values specified in a customized configuration file identified with the -C flag of the ps2afpd command when the transform daemon started. 4. Values specified in the default transform daemon configuration file named in the /usr/lpp/psf/ps2afpd.cfg file. 5. Default values that are built into InfoPrint. These are the same as the transform defaults, except that the default PDF output type is an IM1 uncompressed image. Troubleshooting the parallel PDF RIP client There are certain factors that can enhance the performance of your pdfprs client. This section provides some recommendations. Defining RIPs on an InfoPrint AIX server The more RIPs you define, the greater the performance improvement. However, because a single RIP uses an entire CPU, you should never start more RIPs than your InfoPrint Server can support. The pdfprs client generally uses one processor, so be sure that your configuration can support the number of RIPs that you define and start. For guidelines see Table 23 on page 175. For more information about defining RIPs across AIX servers, see 178. Specifying an uneven number of RIPs If you have PDF files that have simple text data on the front page and more complex image data on the back page consistently throughout the job, a two-RIP configuration will not result in enhanced performance. Since the second RIP always gets the more complex pages, the job will take the same time to RIP as if a single RIP were used, while the first RIP remains idle. Use an uneven number of RIPs to distribute the pages in the job more evenly. Using -p or -g options from the command line While you can specify a page subset for a particular job by using the -p or the -g flags on the pdfprs command, we recommend that you avoid these 180 InfoPrint Manager for AIX: Procedures

Hierarchy of transform options
InfoPrint assigns a hierarchy to its use of flags and configuration-file information
when it runs the PDF transform program. The following lists the order in which
InfoPrint uses flags and information specified in configuration files:
1.
Any values you specify on the command line, including values in the
configuration file you specify with the
-C
flag.
InfoPrint commands process flags from left to right. If you enter the same flag
more than once, InfoPrint uses the last occurrence of the flag to determine the
value to use. For example, if you specify this command:
pdfprs -C8263.cfg -r240 -r300 myfile.ps
The
pdfprs
command transforms the file using 300-pel resolution. InfoPrint
ignores the resolution value specified in the configuration file
8263.cfg
and the
first
-r240
flag and value.
2.
Values specified in the default transform command configuration file named in
Table 24 on page 177.
3.
Values specified in a customized configuration file identified with the
-C
flag of
the
ps2afpd
command when the transform daemon started.
4.
Values specified in the default transform daemon configuration file named in
the
/usr/lpp/psf/ps2afpd.cfg file
.
5.
Default values that are built into InfoPrint. These are the same as the transform
defaults, except that the default PDF output type is an IM1 uncompressed
image.

the second RIP always gets the more complex pages, the job will take the
