I have an InDesign document of about 80 pages with roughly around 80 high resolution TIFFs (one for each page). The average size of each TIFF is around 15MB. When I export it, the PDF's file size is 200MB. The document is for print. When I bring it to a printers some printer can't even print and if they can it can take up to 20 minutes to print it when a normal print job there would take 5 minutes.
Whats the best way of going about reducing the file size? Should I individually resize each TIFF in photoshop or should I use the compression settings when exporting the PDF from InDesign? If the compression is the best method how should I go about this?
