Halftone diagram

Original – Three examples of modern color halftoning with CMYK separations. From left to right: The cyan separation, the magenta separation, the yellow separation, the black separation, the combined halftone pattern and finally how the human eye would observe the combined halftone pattern from a sufficient distance.

Reason: A very useful diagram illustrating roughly how color halftoning works.

Comment: This is more modern half-toning; it might be worth noting that early halftoning could be aesthetically rather different. Partially down to screen angles, partially due to dot shapes. Adam Cuerden ^(talk) 04:33, 6 August 2014 (UTC)[reply]

Will note in the blurb here and article. — Crisco 1492 (talk) 10:00, 6 August 2014 (UTC)[reply]

Comment. I don't understand the use of the "approximately equal to" sign. 86.167.125.78 (talk) 23:25, 9 August 2014 (UTC)[reply]

Depending on laptop settings, it might be off by a very small margin, hence "approximately". It's possible to verify, though a bit difficult. On my laptop, I had to open the image at minimum size, downsize it in Firefox (CTRL + - ), then stand on the other side of the room. It looked the same to me. — Crisco 1492 (talk) 00:04, 10 August 2014 (UTC)[reply]

Well, mapping an RGB display to CMYK colours is a whole different ball game. None of the separation illustrations are proper CMYK colours (arguably with the exception of K), and they only work as an approximation and because our eyes don't resolve the individual RGB elements. By that token all the panels should have the same "approximately equal" caveat. I think the diagram only works at all if we assume that everything is through the same RGB "filter" that shows us the best approximation on our RGB screens of the actual process. — Preceding unsigned comment added by 86.167.125.78 (talk) 00:16, 10 August 2014 (UTC)[reply]

I think you're getting a bit too far. The "approx equals" sign just mean that it looks like that from far enough, but it's not really like that when looked at closely. No fussy RGB conversion or other here: this doesn't detract us from understanding the actual process. - Blieusong (talk) 21:47, 11 August 2014 (UTC)[reply]

You seem to have misunderstood. I'm not "getting a bit too far"; in fact I was actually countering the suggestion by someone else that the use of the symbol was to do with monitor settings. I don't understand your comment "no fussy RGB conversion". Clearly there is an RGB conversion. 86.190.237.29 (talk) 00:34, 14 August 2014 (UTC)[reply]

I might have misunderstood. Anyways, I just meant the conversion doesn't matter and that understanding this diagram is not affected. Print it or whatever and it's still the same meaning. - Blieusong (talk) 18:38, 14 August 2014 (UTC)[reply]

Strong support Clear, clean. I don't think it was necessary to have the operators overlapping the squares, but they don't really distract either. A little technical issue: the PNG renderings don't seem to come from the SVG, but from an enlarged bitmapped version of it. - Blieusong (talk) 11:50, 11 August 2014 (UTC)[reply]
