Subsets
Introduction
Postscript supports the concept of page sets. The page sets are defined by the parameters
NumCopies and Collate. When multiple copies of a document are requested (NumCopies > 1), the
pages are delivered to the output destination in page sets. The boolean value of the Collate
parameter determines the make-up of these sets and thus the order in which the pages are
delivered:
• When Collate is true, each page set contains one complete copy of the entire document. One
copy of each page, with the pages arranged in the correct order. The number of delivered page
sets is equal to the requested number of copies.
• When Collate is false, each page set contains the requested number of copies of each single
page of the document. The number of delivered page sets is equal to the number of pages in
the document.
From the PS concept of page sets, the concept of subsets is derived from handling independent
outputs for parts of the PS file. Page device parameters that normally apply to page sets are used
for subsets.
Create a subset
When you change the value of one the following page device parameter, a new subset is created:
• Staple
• StapleDetails
• Collate
• Jog
• Outputtype
• Number of copies
Toggle the value to create two successive subsets with the same characteristics.
Example:
<< /Staple 0>> setpagedevice
<< /Staple 3>> setpagedevice
For the new subset, the values for the other parameters remain equal as for the previous subset if
they are not specified again. If the following values are set:
/Staple 3,
/Jog 3, or
/Collate true
they are applied for EACH set, even if the values are set once at the beginning of the file.
