Wow, the “Audit Space Usage” function led me straight to the origin of the problem: I found out that I used, inadvertently, a wrong Export-to-PDF profile for the arabic file, a profile requiring no downsampling and no image compression. My bad, but on this occasion I discovered this useful tool in Acrobat Pro!

Jongware, your intervention was, as usual, extremely helpful and informative, thank you deeply for your support. I would like very much to learn more about prepress, can you please suggest me some books I could use?
