When a new logo is to be chosen it is always advisable to evaluate it among two independent sets of people one to evaluate the logo in isolation and the other to evaluate the logo on the pack.
Evaluation of logo in isolation looks at its likeability, distinctiveness, comprehension of message conveyed, by logo options, preference among logo options, and preference of logo among key competition. Evaluation of logo on the pack also looks at the same alternatives along with the speed with which the respondent would identify the test logo pack among a clutter of other similar packs. This helps to evaluate how the logo would stand out in the shelf.
