Thanks a lot so far. Something I am wondering -- after a little bit of research which papers HP is offering -- what makes the difference between their Professional and Premium papers? Premium "sounds" more sophisticated!?
Professional Satin 300 gsm is in this case the better quality; heavier paper base, excellent print quality and possibly no HP logo printed at the back (can not find the sample). It tested not that good in Aardenburg Imaging's fade resistance testing though. Check the HP papers there too, the ones that were printed with Vivera pigment ink.
Next to HP Matte Litho-Realistic (may shift paper white too in time according A-M) the two Hahnemühle produced papers, HP HM Smooth and Textured (Photorag and William Turner quality actually) are excellent. So if they still have that quality available. The HP Prof. Matte Canvas 430gsm is as good as any top quality canvas. The HP ID Premium RC qualities are good but I think Epson shifts the production to Everyday and Universal qualities that are lower in weight.
The official HP catalog in Germany does not show all of the above and I am not sure what is still in the pipeline. Mainly using third party media here right now.
