Continuous business form

摘要

A continuous business form has rows of aligned feed holes along opposite side margins for feeding the form through a data printer which simultaneously prints a complete line of type across the form. A plurality of parallel pre-printed bars of pre-selected bright and clear halftone colors extend across the form, each bar being of a constant width substantially equal to the pitch of the line of type across the form. The bars are printed on a bright white substrate and have a width of at least one-eighth inch so as to permit at the least eight lines per inch of type to be printed on the form. The bars are of at least two different repeating colors and of such a spacing as to effectively avoid confusion and minimize eye fatigue when reading lines of type spaced as closely as eight or more per inch.
