I had need to make a cover design for print. Moreover, I had to make critical elements (photos, line of orbits, etc.) easily customizable for the client. And I managed to create a PSD template with some little scripts to allow users with any skills solve the task. Additional difficulty was it was should be CMYK template, that's why every FX, which could be achieved in RGB with simple color blend mode, in this template was colored and composited be hands from multiple layers.
