PlaceHolders ScriptLines are similar to BlankPages in that they do not contain any information that will appear in the final output file. However, while BlankPages are destined to remain blank in the final diary, PlaceHolders are setting aside pages that will have content in the final printed diary.
•Usually PlaceHolders are used in custom jobs where a client may be supplying ready-made film that will be used along with the output file to burn printing plates.
•They can also be used when the client is supplying a printed and folded signature to be inserted into the diary as it is assembled.
•Another possibility is that the client is supplying his custom pages in an electronic file format that cannot be incorporated into a QuarkXPress output file, but can be merged with it in the imposition software.
Note that you can include references to the Year Property of the Current Script in either the Label and Comments properties of a PlaceHolder ScriptLine, using the pseudo-tokens [year:-10] ... [year] ... [year:+10].
Using the Hide PlaceHolders option of the Generation Options property, you can have theses pages be blank (as if they were BlankPages). But, it is recommended that you leave those identifiers to better differentiate between BlankPages and PlaceHolders in your output file.
