Method for reusing printed waste drawings

The invention relates to a method for reusing printed waste drawings. In daily use, the drawings are inevitably rejected due to factors such as manual operation and change of the drawing design, and great waste is caused. The method comprises the following steps: connecting the waste drawings which are collected in ordinary times by double-face adhesive tapes, wherein the distance between every two connected waste drawings is not less than 2m; rolling the waste drawings into a drawing drum, wherein the two edges of the drawings are required to be aligned in the rolling process; putting the drawings into an iron printing drum, and paying attention to align the drawings with marking scales on the iron drum; putting the prepared waste drawings into a printing machine for printing preparation work, and paying attention to press one surface which is rejected after being printed into a printing pulley; operating equipment to cut the waste drawings tidily; and connecting a computer for printing a figure. The method disclosed by the invention is simple; the reprinted drawings can be used as internal or informal reporting drawings of a department; the effect is good, and a large sum of expense is saved.
