Claim 9:
10. The process of claim 1, wherein the specular correction in step (c) is determined by RSP=m2·GCC+b2,
wherein RSP is the specular reflection,
wherein m2 and b2 are coefficients from a linear regression between the gloss values and the specular reflection of a reference color,
wherein GCC is the, gloss
