Continuous stationery for office machines, etc, such as calculators, where sets of figures are printed in columns, instead of being marked with guide lines across the paper, printed in plae blue or green ink in the conventional manner, has a pattern of guide blocks across the paper instead, printed in a brown colour. These blocks may be parallel strips, normally in sets of three, made up of faint diagonal lines. Some of these strips may extend only part of the way from each edge of the sheet, interrupted by a pair of lines. Pairs of lines parallel to the strips may be located between the sets of three. |
