Preflight: Will Your File Fly

In the beginning was computer-to-plate, which begat digital files, which begat much confusion among graphic designers, printers, and prepress service bureaus because customer files were full of errors and omissions. And there was much weeping and gnashing of teeth until lo and behold, the miracle of preflighting came to pass. And there was great rejoicing because, henceforth, all digital files would be automatically checked and corrected before proceeding to the next step in the workflow, saving many costly remakes and much labor. Hallelujah.
