The printer for an event is requesting that all submitted files not include transparency but the only way I know of printing a good gradient of 2 Pantone colors is to use the overprint method. The method uses a solid Pantone underneath and a Pantone gradient of another color from 0 opacity to full opacity on top.
Is my understanding of transparency off? Will the printer be able to accept this? Or do I need to find another method? If you just drop in 2 Pantone colors into the gradient panel, you get an ugly gray band every time.
