Abstract

Improvements in continuous commercial forms, characterized in that each form is provided with a white substrate that has, at least, one row of feeding holes, aligned along opposite lateral margins of the same to feed the form through a printer that it has a series of selectively changeable printing devices, to print a line of types through the form between said opposite side margins, arranging a plurality of previously printed parallel stripes, of two different bright and different colors, previously chosen, which are they extend transversely through the substrate between said feed holes and perpendicular to their rows, each of said stripes having a half-ink character to be lighter in tone than a solid character printed by the high-speed printer, each strip being constant width and practically equal to the pitch of the type line i Printed through the form, said strips being separated equidistant with respect to the passage of the line of printed types through the form, each of these strips being aligned in the spaces between them with the successive spaces of the printing devices, as the form it moves in the feed direction through the printer, with one of said two colors being at least one of the said stripes per inch (25.4 mm) between the upper and lower margins of the substrate, and the other being these colors the rest of the aforementioned stripes per inch (25.4 mm) between said upper and lower margins, so a greater number of type lines can be printed on the form per inch (25.4 mm) in the direction feeding lines, whose lines are more easily discernible from adjacent lines.
