Advice from Exposition Printing:
You’ll find that if you’re producing more than 50,000 copies of a 160 page letter size or brochure, web offset printing will cost less than sheet fed printing. That’s simply because a web press is about 4 times faster than a sheet fed press. It’s also going to be much more expensive than a traditional sheet fed style printing press but the time savings passes on cost savings to you.

Web offset printing requires presses that cost about $400,000 to $2,000,000. Sheet fed offset printing presses in comparison can cost as little as $3,000 to $200,000.

The world’s premier web offset printing press manufacturers are Heidelberg, ManRoland, KBA UK, Toshiba and others. They produce 50,000 impressions per hour on average.
