its okay, just found it, I think its called halftone.

You are quite right Cheryl, it is indeed called a halftone :lol1:
-
Yes Cheryl it is, it is basically DPI (dots per inch) the lower the DPI the bigger they will be. Usually (but might be wrong) this can only be done on the rip as your software won’t show the dpi and will print out at what you set it too, it has been many years since I dealt with this so could be wrong or ooutdated info 😕 :lol1:
They make great posters for businesses as an abstract picture, we had one of an areal shot of our office block, printed it out and frames it at about A0 size and put it up in reception, got many peoples attention and created a nice abstract (yet recognisable) decor feature.
Otherwise it will be a vignette which is the same but dots get smaller and smaller until they fade to nothing (or back out getting bigger and bigger in to another colour)

A lot of halftones arent meant to be perfect circles, they are oval.
There a lots of different types.
With a plug in filter dont remember which one you can adjust the size and shapes of them, to make more circular/oval etc to achieve different effects. -
there is a demo somewhere on the boards, and it uses a font to reproduce the halftone effect, think it was called pottyoes or something like that, but worked really well
Peter -
Just looked at that demo Peter just posted above (1st one) to make a picture into halftones, its pretty useful.
-
Yes worth keeping I think

Screen prints using half tones save a LOT of headache trying to use fades and high mesh counts etc, simple but effective.

quote Peter:trouble is with photoshop and corel the halftone filter dosnt make perfict circles..quote Steve Underhill:A lot of halftones arent meant to be perfect circles, they are oval.Peter, sounds like you want a "polka dot" filter, or perhaps create a custom brush.
For halftones, there can be different dot shapes, such as circle, ellipse, diamond, reverse dot, etc. Keep in mind that the dot shape "fills in" more where the image has greatest "ink density." So for a typical image, the perfect circles wouldn’t occur because they are being varied to simulate shades within the image.
Something to try. Take a solid black silhouette of the image and then create simulated halftone. Likely the dot shapes created will be fully formed.
