Each HP White layer can carry any opacity value from 0-100% at each pixel. The total coverage is additive, meaning 180% coverage could be achieved with HP White 1 at 100% + HP White 2 at 80%, or any other combination. The percentages shown above represent the maximum possible coverage when each layer is at 100%.
