A few weeks ago I purchased 4 liters of Inktec HP 8940 pigment ink, initially for refilling HP cartridges (bubbjet technology), but to my surprise even in piezo print heads like my Epson WF-7525 it really works well. I even tried to print a photo on Netbit Glossy photo paper using a Colormunki profile and the gloss differential was minimal and overall a good glossy appearance even without the often appearing muted look at area's where magenta is the primary colour used. Only a little bronzing can be seen.
Also black ink gives sharp en deep black letters on plain paper

Later on I will try to experiment with my Epson 1500W and dilute the cyan and magenta ink down to the lighter versions and see what happens.

Because this ink is formulated for bubblejet based print heads (HP), It should be compatible too with Canon (type: Maxify, Pro 9500, Pro-10 etc), Brother and Epson printers.

yes, I can confirm your findings that HP compatible inks - dye and pigment - both work in Epson printers, but probably not the other way around , I did it to use up left over inks I got from friends when they bought different printers. I tried Epson compatible inks in several Canon printers and failed, I got the nozzles clean again, no problem but it was not printing for more than a few sheets. You got Inktec inks by Octopus-office as it appears. I was not happy with their Epson K3 compatible pigment inks - strong bronzing and gloss differences - how does the HP black look on your glossy paper - the Inktec Epson black pigment ink showed a strong metallic sheen against reflecting light (which would go away with a GO overprint...)

Yes, their Epson K3 ink has strong bronzing and gloss differences. The problem is that this HP ink is matte black for text prints, so the "black" with my Epson WF-7525. To overcome the Inktec PB metallic sheen, mixing with Image Specialists PB is recommended. I will try another experiment, in which the PB is filled with half Inktec PowerChrome PB and half CMY Inktec HP8940 ink and the lighter colors made with my diluting solution and the normal strength C and M inks. Inktec Powerchrome K3 has a problem with the PB ink which gives a strange metallic shine. Substituting this with another PB improves the overall print quality drastically. Strangely I had better results with the Inktec Powerchrome K3 inks with my Epson 1500W than using my Epson Pro 3880, with much less gloss differential and bronzing (probably due to the printing engine and not using the LB and LLB inks)

Yes, switching the Inktec photo black with another ink would be the way to go, but I still have
enough ink available from my tests with the R800, I found Chinese inks by Aomya performing quite well. But as you indicate the quality of the print outcome is an intricate combination of inks, papers and the printer hardware/firmware/driver
