Flexprint cable (short for 'flexible printed circuit flat cable') is a form of flat cable consisting of flexible flat solid conductor strips enclosed in a layer of insulation.
BC11A UNIBUS cables are an early example of Flexprint cables, although they contain a large number of narrow, equal-width traces.
