How do you avoid reflections on a glossy pack?

The reflection that ruins the file is the one on the plastic over the label, not one on a dining-room glass. If the batch reads, a shine on the shoulder of the jar does not force a reshoot of the front. Turn the pack until the label sits out of the reflection and mark that face. In Madrid the shine on the cap is chased and the batch text stays illegible. The front comes out with the label free of reflection, even if the cap keeps a shine.
