Do you have a favorite screen angle for one color gradients or is it artwork specific? In your opinion what affects the quality of the gradient more, the lpi, mesh count, or angle? 7.5? 22.5? 52.5 or 82.5? Does angle even matter with a one-color gradient? What about dot shape? Elliptical? Round? Rugby? Do you use a special ink or process for gradients? They always seem to be a challenge. Thanks in advance for your input.
