Mythbusting! (A bit of fun)

[Al Ferrari]

OK, I can't let this continue....when it comes to halftone screening, 90° and 0° (as well as 180° and 270°) are all the same angle.

I was trying to be humorous given the nature and context of the thread.

Apologies if anyone misunderstood my intent.

BTW, Round dots provide better tone transitions than elliptical. But that's a different conversation.

Good one.

Simple, they explained it to me this way: they use Elliptical dots in Australia so here are what the two angles look like:

90° (Northern Hemisphere) on the left and 0° (Southern Hemisphere) on the right.

If you've ever worked in Australia you'll know what I mean.

This is why moiré is such a problem in the horse latitudes.

If you're printing in the horse latitudes you should be using an Equestrian dot.
