Is there a reaason you are not sending a PDF?
Locking everything can probably be accomplished by script, or even by just locking the layers, but anything you lock can be unlocked just as easily, so I don't see it providing any real protection against change.
As Peter says, you could simply lock all layers. Alternatively, the
following one-liner should lock all objects in all currently open
documents (i.e. it doesn't deal directly with books -- rather, you have
to open all documents in the book simultaneously and then run it):
app.documents.everyItem().pageItems.everyItem().locked = true
If I send a PDF, can the images be separated outside of ID? I thought the images, and they are delicately colored paintings, would all need to be done outside of a PDF.
Your expert help on this is welcome and appreciated. I haven't done anything like this for years, and just don't know exactly what to do. The book is being printed on archival paper, and it's half art book, half doctoral thesis type writing.
The printing broker asked for the orig ID files.
Thank you so much! I'm going to wait to see if I need to lock it all down or if I can send a PDF.
Who is doing the corrections?
Normally I would want any photos of art (I do some museum catalogs, so I know what sort of thing you are talking about) to be color corrected and sharpened properly BEFORE placing in ID. My personal preference is to convert to a known CMYK destination space, but if you don't know the space and can't get it (a possibility, especially when working with an overseas printer you don't know) you can do the correction in RGB and export to PDF/X-4 which will preserve the colors and embedded profiles for conversion in the RIP.
If corrections are going to be made by someone else, you probably need to send the native ID files and links, bu t then there is no point in locking, since all the images will need to be unlocked for updating.
And for goodness sake make sure everyone who is involved in color approval sees and signs off on proofs before this goes to press. It might take more than one round of corrections and proofs to get everything right, and it's not like you are going to be able to make corrections on press.
