I'm just experimenting with halftones on my new press (by the way, if you're doing multi-color projects with no micros, stop it. Micros are so amazing) and there's something I'm wondering.

I've read that I should do all screens at 22.5 degrees, and print wet on wet. But if i achieve perfect registration, won't the dots just print right on top of each other, thus leaving white spots where colors in a gradient meet? IE the dots don't get offset?

I'm assuming there's some detail i'm not considering.
Thanks for any hints!

As an example, if you have a 50% green on top of a 50% orange, and they're both at 22.5 degrees, won't the green dots just block out the orange ones?

Yes they do, having the same angles for all colours can work, but it os more susceptible to variation.
Try 18 & 71 degrees at 45lpi (assuming 1440dpi output)

Thanks! Glad to know my logic wasn't way off on that one!
