One option mentioned by photographers is a Plak-it style mounted print. This is a frameless presentation where the print is mounted to a rigid board, which can appeal to clients who don’t want a traditional frame.

Pros:

• Clean, modern look
• Rigid support for a large print
• No frame required
• Can be a good client-friendly presentation option

Cons:

• It may not feel formal or “classy” enough for every wedding portrait or décor style
• Surface protection depends on the print finish and mounting process, so durability can vary

Since you’re concerned about scratching, ask your lab specifically about protective laminates or durable surface coatings on mounted prints. In general, for a large display print, you’ll want to compare rigidity, surface protection, appearance, and whether the couple prefers framed or frameless wall art. If they dislike frames, a mounted print such as a Plak-it style product is a reasonable option to explore.
