Pinball Backglass vs Translite: How to Tell Them Apart and Care for Each

The artwork in the backbox is often what draws people to a machine in the first place. For many collectors it is also a major part of a game's value. Yet backglasses are among the most fragile parts of a pinball machine, and simple cleaning mistakes can damage them for good.

This guide explains how to tell a painted backglass from a translite, what threatens each, and how to clean, protect and store them. It also covers reproductions and what to ask when buying.

Backglass vs translite: the difference

How to tell which you have

• Look at the edge: a painted glass has the art on the glass itself. A translite is a separate sheet behind a clear glass.
• From the back (with the machine unplugged and backbox open), a painted glass shows layered paint, often with a mask of opaque areas around the lit parts.
• EM games with score reel windows almost always have painted glass.

What damages a backglass

Heat

Incandescent bulbs in the backbox heat the glass and the paint for hours at a time. Over years, heat dries out and loosens paint layers, causes blistering and lifting, and fades translites. Reducing heat is the most important single step you can take.

Flaking and paint loss

The paint on old backglasses is applied in layers. As it ages, layers can lose adhesion and start to lift or flake, often first in the darkest or most heavily inked areas. Once paint is lifting, vibration, touch and cleaning can make it fall away.

Physical damage

Glass breaks. Backglasses are commonly damaged when a backbox is lowered or moved without the glass removed, or when stored glasses fall over.

Light and moisture

Sunlight fades translites and can damage paint. Humidity and temperature swings stress the paint and can lead to mould or residue.

Protecting artwork in the machine

• Reduce backbox heat. Many owners switch to warm-white LEDs designed for pinball for backbox lighting, keeping the original bulbs.
• Don't leave the machine on all day when no one is playing.
• Keep it out of direct sunlight.
• Check the mounting: the glass should sit securely without rattling, which can accelerate flaking.
• Inspect the back of the glass regularly for new lifting or flakes at the bottom of the backbox.

How to clean safely

1. Unplug the machine. Remove the glass carefully, following the manual. Have a padded, clean surface ready.
2. Handle by the edges, and keep the painted side away from contact.
3. Front of a painted glass: use a mild glass cleaner sprayed on a soft cloth, never on the glass. Wipe gently and keep liquid away from edges, where it can creep around to the paint.
4. Translite: dust gently with a soft, clean microfibre cloth. Avoid solvents and harsh cleaners. Ask the translite maker or a community about any cleaner before using it.
5. Protective glass in front of a translite: clean both sides like any glass, and let it dry fully before reinstalling.

Removing and reinstalling the glass

Most backglass damage happens in the few seconds when the glass is out of the machine. How the glass is held varies: many games use a channel the glass slides into and a lock or retaining bracket, while others use a hinged or framed insert. Read the manual first so you know which you have.

• Unplug the machine and unlock the backbox. Have a clean, padded surface ready before you lift anything.
• Use two people for large or heavy glass if you are unsure of your grip.
• Lift straight and slowly. Don't let the glass twist in its channel, which can chip the corners.
• Look at the back of the glass as it comes out. Any flakes falling are a sign the paint needs a restorer's attention.
• When reinstalling, check the glass seats fully and evenly, and that nothing in the backbox presses against the painted side.
• Never lower or fold a backbox for moving with the glass still installed.

Storing a backglass or translite

• Store backglasses upright on edge, not flat with weight on top, on a padded surface, in a stable spot where they cannot fall.
• Protect the painted side with a clean, smooth, non-adhesive covering. Nothing should stick to or press on the paint.
• Store translites flat or gently supported, never folded or tightly rolled, away from light.
• Avoid attics, garages and basements with heat, humidity or temperature swings.
• Label the storage with the title and condition notes.

Moving the whole machine? Remove the backglass first and transport it separately and padded. Our shipping and pickup checklist covers the rest.

Reproductions and originality

Reproduction backglasses and translites exist for many popular titles. They let owners display a game with clean art while storing a fragile original, or replace one that is beyond saving. Quality varies, and originality matters to many collectors.

• Ask whether a glass or translite is original or a reproduction. Sellers should disclose it.
• Compare against reference photos of the original art on IPDB or in community archives. Differences in colour, detail or print texture can suggest a reproduction.
• If you replace an original, keep it and pass it on with the machine. It is part of the game's story.
• Don't present a reproduction as original when you sell.

When researching what affects backglass value, look at condition notes in completed listings: flaking, fading, cracks and whether it is original. Those are the factors buyers focus on.

FAQ

The bottom line

Know which kind of artwork you have, keep heat and sunlight down, clean only the plain glass side, and store glass upright and protected. Backglass art is often irreplaceable, so the safest care is gentle and preventive, with a restorer consulted before any repair.
