When dry, a number of the printed samples are selected and their colour is measured as specified in 4.2.4.
The colour difference between each sample and the colours specified in 5.1 are then calculated an d plotted as
a function of ink film thickness as shown in Figure B.1. The ink complies with this part of ISO 2846, if at some
ink film thickness within the range specified in 5.3, the colour conforms to the values and to lerances specified
in Table 1.
