Have you considered/tested engraved insert text? It may not be original, but it could have an interesting look back- or side-lit, and it sounds like the tools are capable.

Although wise to not distribute copyrighted work, it's a real shame that everybody has to 'reinvent the wheel' here. Diner's art is difficult to touch-up (orange is considered the hardest color to match), and the decals and whatnot available are clearly inferior to the original.

I'm both blue in the face from waiting for CPR, and now green with envy for your 'until CPR' efforts. Will you sell your 'good enough' efforts once CPR's is printed? If so, make the announcement, and I can check you every day too!

Orange and blues are almost always spot colors when printed commercially. I couldn't get much more than an orangish brown printing CMYK. And while Photoshop easily created spot color layers, I couldn't find an inexpensive printing option. Have you gone this route?
Between matching colors, and seeing how it printed, I found trial-and-error my best technique and was hesitant to increase the cost of testing. The learning curve seemed about endless, so I set it all aside.
Thank you and I encourage you to continue sharing anything you've learned. (RGB colors maybe please? )

Looking forward to seeing your cash register restore. I had always thought a mod that showed the bonuses with a 'ye-olde' pop-up cash register with Extra Ball! as the drawer opening would be fun.

Anyway, your restore [still] looks great! Nice work!
