Ah the vagaries of software. We want the universal tool set that does it all, kind of like WD-40, duct tape and a hammer. My workflow with Colorprint is import to LR, make adjustments as needed, open the edit through LR to PS, make any adjustments not able to be done in LR, use the Genuine Fractals to do the scaling, save the work and print through ColorPrint 8.
If I want imaged edges I do that in Colorprint. If I want black on the wrap I do that in PS after GF by changing the canvas size with a black base.
