Wayne - also - not clear that the resampling to 360 is done exactly the same way (mathematically) in the Epson driver versus in Photoshop. There's been much inconclusive discussion about this in the past, for earlier versions of Photoshop and Epson drivers. It's an interesting question that perhaps should be revisited - again making a test or two for a SUBSTANTIAL resampling to 360 both ways, and seeing whether there is a visible (naked-eye) difference of image quality (sharpness, tonal gradations) between the two approaches. Time permitting I'm thinking of doing it, but please beat me to it.
In this case I don't think any resampling took place ... I resized the print without resampling to 360ppi, then printed it at the resulting size.
I think your talking about when printing to a specific size is it better to resample with photoshop to 360 dpi, or is it better (or as good) to let the driver resample, which is the recommended workflow presented by Jeff Schewe in the LL Camera to Print video.
There is some logic in my mind that the driver may be able to screen and resize the image in one step better than resizing in photoshop and screening in the driver. But then I'm clueless into the actual math of it all, so my logic may be out in left field
I have recently been using Jeff's approach, sending the master file at native resolution to the printer, and letting the printer driver handle resizing, which outstanding results. The only exception is if I go below about 220ppi, I then uprez the unsharpened version 200%, sharpen that, and again send that to the printer and let the driver size to the final print size.
I have not tested to see if there is any perceptible difference in image quality. The resulting prints are very very good, and it saves so much time in the workflow with great results I haven't really thought about "testing" it. I suppose upon micro examination there may be a difference, but Jeff is pretty clear on the video that normal viewing distances and the ability of the human eye are an important reason why he recommends this workflow.
Since I'm having a lot of fun playing with my new printer, maybe I'll try some tests.
