No. "One of the most unique pressing surfaces..." is a correct noun phrase, a group of words (without a verb) based on a noun. The noun in the phrase is 'surfaces'.A noun phrase functions as a noun as the subject of a sentence or a clause and as the object of a verb or a preposition.However the phrase "most unique" is grammatically and symantically incorrect. The word "unique" means "one of a kind." It is impossible for something that is unique (one of a kind) to be more one of a kind, or more unique, than something else. Consequently it is impossible for anything to be "the most unique."An equivalent but grammatically correct phrase might be "one of the most distinctive pressing surfaces..."
