Here I took the test. I pass the photo SUB flow of tap water for several seconds. It's not moving. Surprising.
I like the quality papers, thick. This one is perfect.
And I used it for now with a printer "low end" inkjet color HP Deskjet 3055A that I bought 50 euros. Well ... what a surprise to already get great prints with this basic printer.
I look forward to testing this paper with a photo quality printer, it should be even better.
