Patch 1, 22, 43, and 64 have no ink- i.e. they represent the paperwhite

they are the white patches.
Hi,
it doesn't look like these patches are white:
1 "1" 8.3200 7.9700 5.9900 8.3500 92.910 0.62000 -4.0000
22 "22" 7.6500 7.2900 5.1100 7.6500 93.500 0.71000 -4.3000
43 "43" 8.6700 8.4300 6.5800 8.7600 92.560 0.67000 -3.7000
64 "64" 7.7100 7.3500 5.0900 7.7400 93.430 0.73000 -4.4100
Notice that the CMYK values are not 0.0
What created the original test patch values ?
Graeme Gill.
