Laser etching doesn't come off with acetone (and is usually much harder to read, being more like embossing than printing). That's silkscreened ink.

I'm talking about the 'Another Chip' IC, which has laser writing. It's the bottom one in the header image. They use a coat of paint to obscure previous markings, then use the laser on that, resulting in brownish text (not embossed).
