    From Prior Art:
    Thanks everybody for the great response! We’re really flattered by the interest this project is generating.

    To clear up a few questions:
    -Madsci is right, we don’t use lasers (though we think they’re pretty cool). We coat our plates with a protective lacquer, then engrave them using a diamond scribe, and finally treat the plates with a chemical oxidizer to blacken the engraved lines. It’s an involved process, but we think the final results are stunning.

    -And as for the resolution issue, Google’s patent database has incredibly high resolution scans, which we then convert to line-art. There’s no pixelation, only clean lines. Check out the gallery for some examples.

    Anyway, thanks again to all you Happy Mutants for the great response. Happy…… mutanting?

    Ah! I’ve been looking for an image to complete one of the Christmas gifts I’m making this year, and I hadn’t even considered patents. This is brilliant; thanks for posting!

    The title says “laser-engraved” but the quote says “router” and the FAQ says they use diamonds (a diamond cutting head on their CNC router perhaps?). Curious internet monkeys want to know! Which is it?

    I find the USPTO site still does a better job finding patents. Clunky interface, but it works. Sometimes Google flat out refuses to find issued or published patents. However, Google lets you download as PDF’s. So I use both.

    How high resolution is the source material? Copper engraving, when done by hand, involves a certain economy and fluidity of line. When stray pixels and aliased artifacts guide the scribe, that aesthetic quality is compromised.

    This reminds me of a book I just read….now if they could only make them in 3d.

    I want a diagram of some absurd automatic page-turning device from the 1880s to use as the cover of my next ebook reader…

    If you’re looking for ideas, this book should help:

    I absolutely love this concept!! Outstanding!! I’m thinking a patent of the first washing machine would be so radical!! You all rock, now my gift list has gotten shorter!

    Nowhere does that site mention lasers. In fact, they state in at least two places that the engravings are done with some sort of diamond scribe.

    If only the images submitted for patent 4,022,227 weren’t so crude.
