Have you done it? Tell me about it. I know this is vague.
Basically I want to get some cloud-like halftone texture on a poster. Not cartoony clouds, but white halftones on a blue sheet. For some reason I'm feeling particularly retarded and want to know how it's worked for yinz.
Let's say I take this image here and I want the white to print.
Do I make it a bitmap, invert the colors, and halftone that?
Take that image into grayscale, invert it. Punch up the contrast and fuck around wiht the sharpness etc to get it how you want it and see how it looks, if the halftone aint looking how you want it go back and adjust it and go back and forth til you got it how you want it. Then end.
