Every company needs "literature," printed pieces that do a careful and well thought-out job of presenting its products and services: catalogs, newsletters, product sheets and brochures, letterhead, business cards, presentation folders, specification sheets, case histories or application sheets, special event brochures, annual reports, manuals, technical bulletins, posters, product insert sheets, labeling, recruitment materials and so on.
With the increased availability of powerful desktop publishing systems and software, many companies decide to meet these needs internally. Resist this impulse. Your homegrown materials will betray their off-the-cuff origin to most of the people who read them. Appearance is reality in marketing, and you have to look as professional as you are. And no matter how creative you are, a commercial copywriter or graphic designer can vastly improve almost any materials created by an entrepreneur.
