Hi the 300 TAC profile is best for web and the 330 TAC profile is best for sheet fed. However there are some conditions where the 300 TAC version is best for sheet fed presses, i.e. long perfectors etc, and in some cases, with good web presses and papers, using the 330 TAC profile will give a great result.
