• Find and fix production errors twice as fast
  Preflight while you design. Continuous preflighting alerts you to potential production problems in real time so you can quickly navigate to a problem, fix it directly in layout, and keep working.
  
  
• Adjust images in half the time
  Use the new Adjustments panel and fluid on-image controls in Adobe Photoshop® CS4 to make changes in half the time required when using Adjustment layers, menu commands, and dialog boxes in earlier versions of Photoshop.
  
  
• Nimbly manage related artwork with multiple artboards in a single file
  Keep up to 100 related artboards in a single Adobe Illustrator® file to reduce organizational headaches and streamline project editing. Save, export, and print artboards independently or together.
