I see this effect on occasion and never really looked at it. Is this a Photoshop filter or is it hand stippled? It is the 100% white to 0 on the black shirt. Same thing on the blue and orange and blue and white.
Has anyone done an effect like this or know how it's done?

You can try to use "dissolve" instead of "normal" on a new layer.
Then do a graduation fill on the new layer to see if it is the effect you are looking for.

I was going to say the same thing if to look for a faster, cleaner way.
To help simulate a more rounded speckle tho, try adding a slight random texture to that layer (merging the layer and texture). Don't use a texture with a high contrast.
Then I use a much lower resolution such as 75-100 and apply the dissolve to the layer. Copy/paste into channels, then blurr a bit to round off thr squares. now, hold down the control or camand key and click on that channel. bring the selection back into layers. fill with black. now, raist that resolution to match your original.
Another good and maybe better way is to use the noise, gravel effects. With same steps above.
The best way is to print out line art for a guide, lay paper over top, use black India ink and a tooth brush. Dip a little in brush, tilt in the direction and run fingertip over brush tips to flick a spray of ink in your desired amount. Dry and scan. This looks more authentic. Random sized stipple.

Isn't there a Rapidograph filter? ;D

Back "in the day" we used to use an airbrush with the pressure turned down way low to get that effect.
Nowadays you can airbrush in Photoshop using the Dissolve setting or use a hard-edged brush with Scattering settings turned on.

Do any of you have a sample that you did or can do a quick Photoshop rendering that will simulate this? Post a picture if possible? I know this takes time out of anyones busy day but I would like to see if it can be duplicated. I am going to play with some Photoshop stuff that was mentioned and see what I come up with.

A lot of times I will do my more complex (Ha! 4 color hand press shop) seps in p-shop and import/assemble/output in Corel. `Twas me, I would p-shop select all areas of a particular color, (through paths/channels/layers, etc. ,your preference) save that selection to a new pshop file in Grayscale, convert to b/w tiff...(you will need to invert image first because the new file will pop up as a negative image of your original sep.) Under your tiff options, select grayscale, then bitmap method, (dot type) should be "diffusion". Here's the rub, the diffusion dots are smaller than most of your rapidograph era hand stippled dots. If they are unacceptably small for your taste/needs, you will have to create your seps at a smaller percentage (of final size), assemble/arrange (ctrl "C" to center, ctrl "E" to vertically center) with one another in Corel, select all tiffs, then enlarge until the dots are scaled where you want them...Clear as mud? LOL! Hope this helps!
