CHAPTER 3: Documents Basic Page Layout 23
Defining bleed and slug areas
Within InDesign, a bleed or a slug is an area outside the page margins that can be printed or included in an
exported PDF. Typically, these areas are used for objects that extend beyond the page edges (bleed) and
job/document information (slug). The two areas can be printed and exported independently; for example,
you might want to omit slug information for the final printing of a document. The following script shows
how to set up the bleed and slug for a new document. (For the complete script, see BleedAndSlug.)
myDocument = app.documents.add();
//The bleed and slug properties belong to the documentPreferences object.
with(myDocument.documentPreferences){
//Bleed
documentBleedBottomOffset = "3p";
documentBleedTopOffset = "3p";
documentBleedInsideOrLeftOffset = "3p";
documentBleedOutsideOrRightOffset = "3p";
//Slug
slugBottomOffset = "18p";
slugTopOffset = "3p";
slugInsideOrLeftOffset = "3p";
slugRightOrOutsideOffset = "3p";
}
Alternately, if all the bleed distances are equal, as in the preceding example, you can use the
documentBleedUniformSize property, as shown in the following script fragment (from the
UniformBleed tutorial script):
//Create a new document.
myDocument = app.documents.add();
//The bleed properties belong to the documentPreferences object.
with(myDocument.documentPreferences){
//Bleed
documentBleedUniformSize = true;
documentBleedTopOffset = "3p";
}
If all the slug distances are equal, you can use the documentSlugUniformSize property, as shown in the
following script fragment (from the UniformSlug tutorial script):
//Create a new document.
myDocument = app.documents.add();
//The slug properties belong to the documentPreferences object.
with(myDocument.documentPreferences){
//Slug:
documentSlugUniformSize = true;
slugTopOffset = "3p";
}
In addition to setting the bleed and slug widths and heights, you can control the color used to draw the
guides defining the bleed and slug. This property is not in the
documentPreferences object; instead, it is
in the
pasteboardPreferences object, as shown in the following script fragment (from the
BleedSlugGuideColors tutorial script):
