X_rite Dtp_41. Is there something wrong with the function "xsp_Tdensity"?

status T density
measured with X_rite Dtp_41 (VCMY)0.504, 0.264, 0.768, 0.453
Calculate by "xsp_Tdensity" (CMYV)0.242, 0.521, 0.423, 0.352

Hi,

The table "xspect denT[4]" has incorrect scale factors. Change the
four "Log10 Scale factor"s to 1.0, and you should get the expected
density values.
