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?
