PDF Press for Mac

From BulletProof:

• Works with all OS-X applications that Print.
• Takes PDF Output of "Print to Preview" and converts it to a flattened high-resolution, anti-aliased PDF image that will print without quirks on all printshop-RIPs, color laser printers and color inkjet printers.
• Does not require special knowledge or expertise to use. "Fuzzy logic" algorithm selects output resolution based on 4 simple pieces of information.
• Just drop Preview's PDF output onto PDF Press, and Save the results.
• Within the limits of your print shop, your printing will look like the image in Preview.
