If you looked at the shipments per employee data for the commercial printing industry over time, you’d be convinced of a history of productivity improvement that must be making everyone wealthy beyond their dreams. Since 1994, using manufacturing shipments data from the Commerce Department and employee data from the Bureau of Labor Statistics, each employee has added $70,000 of shipments value to their job.

about $500 per year. The rest is inflation.
The number is in the range of $177,000 per employee, and it recently peaked in Spring 2011 at about $183,000. In 2008, it was as high as $186,000. These vary by segment, but those data are not available in a monthly format that allows continuous analysis. Commercial offset is in the range of $225,000 per employee, while pre- and post-press businesses average about $140,000. Data about all 12 NAICS segments as defined by the Commerce Department are not available consistently.
