Thanks
All good suggestions, but only John's method addressed my concern of printing two colors on a light pique shirt, wet on wet, because of the textured edges picked up by the next screen, and then offset to the next shirt.
On a dozen or two shirts, John's method is pretty involved and would add a lot of cost, and it too would only be wet on wet after the smoothing "body filler" is added.
The shirts have arrived, Gray Port K 320's, and they are not as rough as I had feared, but nonetheless, I expect extra care will be needed.
I don't have puff additive, or 3D additive, and the shirts are due Tuesday, so will just make the best of it, flashing between the black and the orange.
I will use the technique of a first heavy stroke, driving the ink below the peaks, and into the valleys followed by a lighter stroke, not dissimilar to the way I learned to do whites, though counter to the "keep it on the surface" mantra of plastisol in general.
