The Evolis 1/2 YMCKO Color Ribbon is a half-panel color ribbon for ID cards that feature a color ID photo and some black resin printing (for text, logo, or barcode). It prints color on one side, generally for an ID photo. This ribbon has the same specifications as the standard full panel YMCKO color ribbon, but the yellow, magenta, and cyan panels are half the length. While the length of the black (K) and overlay (O) panels is 3.86" each, the length of the Y, M, and C panels are 1.93" each. The advantage is a savings in cost per printed card when you personalize just a part of a card in color.
