We develop documents in InDesign. Sometimes we get the docs printed by professional printing houses. What is the best way to prepare files for a printer?
Option 1) Simply save a press-quality PDF and send it out
Option 2) Save a Package in InDesign with a fonts folder, IDML, InDesign and press-quality PDF
I noticed that when we do option 2, the InDesign file in the package is much smaller (file size) than our original InDesign file. Why is this? Is it an issue to provide a printer the smaller InDesign file?
You need to ask the printer what they want: Do they want PDFs? If so, what PDF preset should you use? If not, should you package?
Different printers have different workflows. There's no substitute for asking them what works best with their workflow.
As far as the file size difference, the copy in the package has been cleaned out of the useless change data....
