A few months ago I ordered 2 Piezography Pro sample prints of an image file I provided, warm-neutral toned, one on Hahnemule Photo Rag, the other on Canson Platine. The image file contained a 50-step wedge and some photos that had a lot of tones at the low and high ends of the scale.
The Canson Platine sample print has a lovely deep warm tone and beautiful finish - but the low values are depressed compared to the Hahnemule. The 2 prints are a match at the high end, but the lower 1/3 of the scale on the Platine sample is overly dark with less separation: a lower, less linear quality than I’ve grown accustomed to with Piezography on matte papers.
Lately I’ve gotten around to printing with Platine on my Epson 3880, using a mixture of the Warm and Neutral profiles in the Community Edition. I’ve noticed that I always need to apply a Photoshop “gamma” correction to lift the lower 1/3 of the tonal scale. At this point it’s hit-or-miss which is an unacceptable approach in the long-run.
Was your Canson Platine profile off ? Is there a newer profile available for that paper ? Do I need a custom profile made for my printer ? Is it best for me to make my own profile ?
I have a Datacolor Spyder spectrophotometer, which I don’t believe is one of your supported spectros. Do you recommend higher-end spectros because they are more accurate or consistent ? Because they provide automation features which make it easier to measure targets with more patches ? Or why please ?
Thanks for your help as always !
