Creating an Optimized PDF
Save your document as an optimized PDF before sending it to the printer. This will reduce the file size and free up printer memory for processing your job without creating and noticeable differences in print quality. This could mean the difference between 20 minutes of PROCESSING time and 20 seconds!
Open the file in Adobe Acrobat. Notice the file size.

Back in the PDF Optimizer window, click the OK button.
In the Save Optimized As window, save the file under a new name that identifies it as the optimized version, such as adding -opt.
Notice the decrease in file size.
