Printed pink samples
Seventy-three of CU’s general printed samples were
collected regardless of types of paper. Some printed
samples were varnished or laminated. They were
measured and converted to CIELAB values under the
same condition used for measuring of the pink
cushion. Fig 3 shows the pink printed samples in CIE
a* b* diagram. It can be seen that most color data of
the samples were found in quadrant 1 and 4 having
hue angles deviated from the CIE a* axis of 46o and
326o respectively. The minimum-maximum of
chroma (C*ab) and lightness (L*ab) values of 2.26-
70.90 and 38-92 respectively.
