Thanks Rainer..
What artificial detail 100% are you referring to..
also you put 180/300 or 360. What do you print at 180?
Also with the grain and noise, Why do you do it after converting to 8 bit and why do you convert to 8 bit if I may ask?
Also for a printer like the HP is Adobe RGB which I usually always work in or would ProPhoto give better color range.
All new to the Printing.
The Printer said that giving him the files in 16 bit would render a better image.?
I really appreciate the advice.
Also Looking at my image at 100% in Photoshop after upscaling should give me an idea of the Sharpness or how the image should print sharpness wise at that same size as it will be?

T already explained the "artificial detail" slider i mean. it adds some fine grain, although very subtle. i often add also at the final stage some dxo grain to the image. goal of all this grain festival is to hide the smearing of the fine details which can appear if you enlarge very big. experiments can bring here very good results, which differ a lot. unfortunately this is very hard or impossible to judge at the monitor, you should make smatter test prints of this detail zones to judge the right amount of edge sharpness and grain. its not a little work.
i go in the final images often to 8bit because 8bits are enough if there is no further color or gradation editing needed.
in general i use for hiend prints on epson pronters 360dpi, but at very big sizes sometimes may appear problems. so is the new epson 11880 with epson printer driver not able to print sizes over app. 190 x 160cm,- he will make in this case a white stripe and go on behind this with the print.
obviously a bug. with 180dpi the visual difference is very very subtle compared to 360dpi, but the 11880 accepts than the double size because the file size is just half as big. and you will notice the differnece with a loupe..... hardly with the eyes ,- and this at sizes over 2 meter is really not a big deal. 300 dpi is afforded for many other printers than epson.
i add sometimes some small amount of noise in ps ( this described 4% gaussian blur ) to the image before upscaling and scale up with this noise in the image. reason is that this noise nearly dissappears in the upscaled image but helps to hide exactly the same fine detail regions which ends to give a smeared look, the upscaled noise merges itself in some way in the detail ,- this smering i mean you can often see in grass or little stones or other repetitive but random and fine patterns.
only to add noise in the upscaled image may easily look artificial.
no idea about photo pro or adobe rgb. i normally use adobe rgb, or eci rgb.
