Review with Adobe Acrobat Professional your PDF files before sending.

  • Do not review with unconfigured Adobe Reader, because of the lacking of the possibility to see missing trim/bleed issues (no visible bleed) and faulty overprint problems (showing only yellow separation).
  • Do not create PDFs with Acrobat PDF preset "Standard". This creates a PDF files to be printed to desktop printers or digital copiers, published on a CD, or sent to a client as a publishing proof. This set of options uses compression (low quality image of JPG) and downsampling (low resolution image of 50 dpi) to keep down the size of the PDF file.
