DEFINITION

Classification: 400/213

For impact of successive type-face on one field of ribbon in path not parallel to longitudinal extent of ribbon (e.g., "zigzag", oblique, etc.):

(under subclass 211) Subject matter wherein type-face* elements strike the same print-point* of a typewriter in a series of impacts against a ribbon* that moves in a length direction between successive impacts and that has a zone of a particular color, the dimensions of which zone correspond to the length and to at least part of the width of the ribbon, and wherein succeeding elements impact the zone at areas of the zone that are spaced widthwise as well as lengthwise of the ribbon.

(1) Note. The path of the successive impacts on the ribbon so moved may be zigzag, oblique, sinusoidal, etc., as the ribbon moved longitudinally and transversely of the print-point.
