Claim 9:
10. A method according to claim 1 further comprises the following steps subsequent to step (ix):
(xi) defining a food contact packaging surface onto which said ink composition(s) are to be disposed and calculating the area AP-MAX of said surface which corresponds to 100% coverage of said surface with said ink or coating composition(s);
(xii) defining an area AM which is the surface area of food contact in the exposure model on the basis of which said specific migration limits (SML) have been established in step (iii);
(xiii) calculating an adjusted migration level (ML-A) which is specific to the food contact packaging surface defined in step (xi) wherein ML-A=ML×AP-MAX/AM;
(xiv) selecting one or more ink or coating composition(s) suitable for unrestricted use on said food contact packaging surface if the ML-A values of all substances in said composition(s) is less than said SML(s).
