Should I use lamination on both sides if only one side has colored printing?

If the piece will see handling or wear, laminating both sides is worth it even when only one side carries full-color printing. The back-side film protects against scratches and damage and extends the life of the card.

• Double-sided lamination: better all-around protection and durability.
• Single-sided lamination: costs slightly less, but leaves the back exposed.

For anything that gets carried, mailed, or handed around a lot, both sides is the safer call.
