FIELD: printing industry.
SUBSTANCE: method of draft mode printing is carried out by means of conversion of pictures into contour sketches. At first graphic primitives are extracted from a flow of printed data or a printing task. Then the above graphic primitives are combined into pictures in accordance with their geometrical proximity. Then the produced pictures are converted into contour sketches. Afterwards a flow of printed data or a printing task is modified by replacement of a part of graphic primitives with produced contour sketches. Further the modified data flow or printing task is printed.
EFFECT: saving ink, toner of a printing device without loss of recognisability of printed images.
