Injection molding manuals long ago suggested putting some text like the trademark around the point the sprue enters. Camouflage. I had a little Aha moment when I read that and recalled noticing the dimple on old bricks.

With some exceptions (80s plates with sprue on short end) I expect to find the sprue mark on a corner stud.

Anyhow I'm imagining after-market ways to add texture.
