Most cabinets use plexiglass to cover their Control Panels, and artwork is usually sandwiched between the wood/metal panel and the plexi. Over time there can be scratches on the plexi from overall usage.
For CP's that don't have plexi installed, there are options to have the artwork (aka CPO - Control Panel Overlay) be created with a polylaminate coating that gives the CPO a rough and tough texture, impervious to scratches.
