Screens for a picture

[Ryan Mahn]

I work at a print shop and I was wondering if anybody has ever heard of screening a picture? It is were you lay dots over the screen and I understand you would have to make another layer over the picture but then I need dots to be layed over the picture and I just can't figure out how to do this. I have tried the pixelate command and I am not getting the results I want. Can anybody help??

Ryan,

Can you post an example of the effect you're going for? It's a little difficult to understand what you're after based upon your description ... a picture is worth a thousand words ...

[Cecil Copeland]

The only thing I can think of right off hand is Filter>Pixelate>Color Halftone ...

Is that what you're speaking of??

[BLUDVLZ]

My initial thought too... the color halftone, that is. Just not sure enough to stake my name to it. But if we both had the same idea, maybe that's it after all.

Well, screening would have to do with the output of the file - you can however emulate halftone screens in photoshop.

You can also get halftone screens when you convert from greyscale to black and white mode. This is assuming you are not looking for color halftone screens.

Ryan,

Screening is normally done when printing the file (as separations) to a
PostScript device where you can state dot shape, linescreen frequency and
screen angle. This is all available from the Print Menu.
