Howdy folks, still working on my first job, and it just happens to be halftones. I don't have a rip, i'm using photoshop cs3. It's a white print on black tee. My question is that the darkest part of the image (the black) doesn't need ink because it's black and the shirt is black if that makes any sense at all. How do I print the haltones image without the blackest part??
