Yellow and blue Pantone colors were printed on a substrate with high Optical Brightening Agent (OBA) levels and then measured under different measurement conditions as outlined in ISO 13655. Both colors exhibited large DEOO shifts with lighter screen tints, as more paper influenced the measurement. The Pantone colors were further analysed after being printed on two different substrates with varying OBAs. While the solids were color-matched to a DEOO of less than 1.0, the tints resulted in DEOO values above 7.0 due to more paper influence in the lighter screen tints.
