How do you create a halftone pattern in a shape?

How to create halftone pattern in a polygon shape?

[Bojan Živković · Accepted solution]

What exactly you want to ask? How to clip halftone effect to some shape or how to limit effect to certain area or something else? You can use layer, vector, clipping mask, to paint on blank layer or you can erase content on layer then to apply effect.

I need to create a halftone pattern of a painted area. I know how to make halftones I need it to look like the images attached. I have tried changing the angles but still can't get it .

as you will see the halftone pattern forms little circles/ moire's 

[Semaphoric]

There are a few different ways  to do halftones. What method are you using?

[RVB DES]

For this I was using the pixalate> color halftone option it has been the closest I have come to the required images above but not right . needs to be like the color image. if you could help would be great.

Create the Pattern with circular Shape Layers, blur them and Edit > Define Pattern for a pertinent section, then use it as a Hard Mix Pattern Layer.

@RVB DES — The halftone dot shapes in your example appear to be pentagons. Is that what you want, a halftone dot with a five-sided shape?

If so, this technique might get you there:

Or do you want to customize the rosette dot pattern (screening pattern)? If you want to do that, or if you want the halftone dot to be vector-based, that might involve some custom programming in Adobe PostScript. For example:

Thank you I have tried both of those be before but not getting exactly what is needed. I appreciate your help.Once I get to it i'll be sure to share it here as well.

HI Thank you this is a step in the right direction. I think I have might have been a bit unclear in my question. 

So far what you have given me is right n the way the dots form a kind of rossette. Only thing is I need it to be as a gradient where the clusters if I can call it that gradually gets smaller. if that makes sence like the black and white pic I have attached. I hope this makes any sence.

Blend Mode Hard Mix 

[RVB DES]

That is 100% what I need! thank you. any chance you can walk me through this ?

• First create the circles for one hexagon 

• arrange those to the pattern 

• blur the whole thing 

• create a Selection for the repeating section and define the Pattern

Actually I may have underblurred and even the radius of the basic circles could possibly be improved (you may want to use Smart Object instances so you can change them all in one go) – I just did it quickly, one could probably approach the issue much more precisely by calculating relations of white and black areas etc. 

[RVB DES]

Cool that is fine . now how would I get the nice gradient that you had in the photo titled Blend mode hard mix?

[RVB DES]

Again thank you for helping 

[c.pfaffenbichler]

Just create a dark gray to light gray gardient under the Hard Mix Pattern Layer or paint something. 

You may have to experiment, but a white to black grasient will probably not work out well. 

[RVB DES]

Sorry for all the questions. I feel stupid that Im not getting it . I created the pattern fill layer but don't know where to go from there to get the above result. If you have time to explain it to me would be great. to figure this out would help me so much 

[c.pfaffenbichler]

Did you set the Pattern Layer to the Blend Mode »Hard Mix«? 

Could you post a screenshot with the Layers Panel visible. 

The coloring was done above the Pattern, with a Solid Color Layer set to Blend Mode »Screen« by the way. 

[RVB DES]

[RVB DES]

Sorry im kinda new too this 

[c.pfaffenbichler]

There may be a misunderstanding. 

Every Color has to be done separately. 

A Hard Mix Layer atop a color image gets results like this: 

Effectively you need to create a manual neutral separation for each color. 

[RVB DES]

That I do understand im just woking on here to figure out the effect. 

In the actual artwork all colors will be spit onto it's own layer . 

So to back track . 

1. I have a layer with the pattern fill - set to HARD MIX.

2. above that I have a layer with the screen color - Blending mode set to SCREEN 

3. where do I go from there?

[c.pfaffenbichler]

Unter the Hard Mix Layer there needs to be the neutral gradient (or whatever else). 

In my last screenshot that was a white Solid Color Layer at the very bottom and atop that a black Solid Color Layer with a Layer Mask to create a fall-off.

Good day sorry to bother you again but im still doing something wrong and just not getting it . I have attached what my layers looks like . if you could shed some light I would be greatfull. Thank you for you replies so far I know it must be irratating dealing with someone like this.
