Bitmap imagery in photoshop - how do you get the circles perfectly round?

Endre Berentzen's picture

When creating a bitmap image (halftone screen - round) I have a problem getting the circles perfectly round no matter which resolution I start with and which frequency I use. I want to use them pretty big for a museum wall decor but they just look rough no matter which settings I use. Any ideas???

There is very limited control, but perhaps the ill sounding Rastorbator can help you out.

With a bitmap, the circles aren't going to come out looking perfectly round unless your output resolution is really high.

Does the output absolutely have to be a bitmap, or will grayscale do? Because you could just create the bitmap at, say, ten times the target resolution, convert it to grayscale, and then resize the image down to 10%. You should end up with nice anti-aliased circles.
