SECTION 10.10 Prepress Support
KEY TYPE VALUE
Version array (Required if AnnotStates is present; must be absent if LastModified is present)
An unordered array of all objects present in the page description at the time
the trap networks were generated and that, if changed, could affect the
appearance of the page. If present, the array must include the following
objects:
• All content streams identified in the page object’s Contents entry (see
“Page Objects” on page 144)
• All resource objects (other than procedure sets) in the page’s resource dic-
tionary (see Section 3.7.2, “Resource Dictionaries”)
• All resource objects (other than procedure sets) in the resource dictionar-
ies of any form XObjects on the page (see Section 4.9, “Form XObjects”)
• All OPI dictionaries associated with XObjects on the page (see Section
10.10.6, “Open Prepress Interface (OPI)”)
AnnotStates array (Required if Version is present; must be absent if LastModified is present) An
array of name objects representing the appearance states (value of the AS
entry) for annotations associated with the page. The appearance states must
be listed in the same order as the annotations in the page’s Annots array (see
“Page Objects” on page 144). For an annotation with no AS entry, the corre-
sponding array element should be null. No appearance state should be
included for the trap network annotation itself.
FontFauxing array (Optional) An array of font dictionaries representing fonts that were fauxed
(replaced by substitute fonts) during the generation of trap networks for the
page.
Trap Network Appearances
Each entry in the N (normal) subdictionary of a trap network annotation’s
appearance dictionary holds an appearance stream defining a trap network asso-
ciated with the given page. Like all appearances, a trap network is a stream object
defining a form XObject (see Section 4.9, “Form XObjects”). The body of the
stream contains the graphics objects needed to paint the traps making up the trap
network. Its dictionary entries include, besides the standard entries for a form
dictionary, the additional entries shown in Table 10.53.
