Non-uniform halftone

[jtlapp]

I created a halftone out of the color #EBEBEB with contrast at 100% (because I can't use transparent pixels on T-shirts).

This is what I got at 45°. There are 4 quadrants at distinct dot sizes, and thus distinct shades of grey. This doesn't look very nice.

Is there any way to fix this? I fear that I won't be able to use the halftones on my shirts.

I just found a solution: use only integer cell sizes.

No, using only integer cell sizes isn't sufficient to solve the problem. The 45° halftone here is cell size 7.

There are also problems at 0°, as you see in the second photo below.

(I've confirmed that these are issues with the underlying raster, not just with the screen zoom level.)

I'm thinking that Moire patterns may be unavoidable for some half-toned colors, particularly at 100% contrast.

But I'm also thinking having four quadrants each at a different shade (first example above) or two halves at different shades (last example above) is something that can be avoided.

Update: I've been struggling enough with halftones that I decided to write my own program for creating them. Only I'm generating random dots at relatively even spacing, instead of regularly spaced dots. What's better, random dot shading doesn't produce Moire patterns on resize. Here are examples of resizing halftones vs resizing my random-dot fills.

Do your programmed random dots produce a different result from the built-in ‘Noise’ feature?

Absolutely. It provides complete control over dot size, minimal dot spacing, and threshold for completing the fill.

What it going to call it? "Dot Tone" "NonTone" "RandomTone" "AltTone"

Oops!

"Dot Tone" "NonTone" "RandomTone" "AltTone"  

Or "AceTone", perhaps?

Sounds good if you say it as Movie voiceover man "AceTone, for epic dots...Every time"
