PI 400 -- The Who's Who in Printing

Each year, we continue to refine our list. As was done in several past years, we eliminated greeting card companies and several paper converters because they do not really compete in the commercial printing marketplace.

In addition, those firms on the list that are heavily involved in activities other than printing were instructed to indicate sales derived only from printing. If printing revenues comprised less than 50 percent of total corporate sales, companies were asked to give only the amount of their annual sales derived exclusively from printing.
