 Re: Seperating artwork for screen printing
Good tutorial. The problem is when you have complex gradients and color blends. Selecting the colors properly and making the channels stack up for an accurate on screen preview is a whole different animal.
Separating spot colors is exceptionally easy, gradients on a black shirt- now that's separation. I would use the select color range option instead of the magic wand, but your technique is spot on.
Try separating the image posted. This is where fast films, and easy art, and quick seps really show their value. This can be done manually, but it takes a lot of time, and an extreme learning curve. |
