First You need to know if the colors you want to reproduce fits in your printer color space. sRGB has nothing to do with your problem at this stage.
PrintFAB promised to make a linearization print possible but never delivered it.
I can say unlike canon, brother printer if set up to use "other photo paper" will use the CMYK + K ink.
That is why I changed the pigment black for Dye black, to be able to print photos without the bronzing effects.
seems like hp ink flow protection system is having problems in these printers. It it on purpose I do not know. Canon has no such evil inside their printers.
Yes I've done this multiple times with other media/printer etc.
Does the GO optimizer sprayed with say dedicated printer (P900 has no GO optimizer AFAIK) the results would be comparable with coating with hair spray, or better / worse?
You do not write about the colormanagement side of things. The workflow is OK, AFAIK.
Except the creative part should be automatic if you shoot the card in same shot as image.
There should be no need for manual color tuning as this is not analog film scanning.
Could be the bronzing effects, I expected the original ink to be way better in this regard, the meatamerizm under different light sources like daylight an halogen is unacceptable too.
As you know X-rite did not develop anything, their spectrometers are released with rev A as first but usable with at least rev D. Their XRGA standard is a scam is a way tactics to turn attention from the fact that they slept under a rock for few years manufacturing spectrometers that did not...
I will test +25 all CMY colors on the "color management off" advanced button. To see if it increases color gamut or not. I do not have an idea if this setting works at all.
What has display to do with this. I posted epson oem profile compared to data sent to printer (bigger color space color dots) and printed result (green dots) with color management off. Conclusion is that epson has made their profile by printing more intense colors then by simply turning color...
There is no sutch thing as "maintenance tab - extended settings - print density"
However there seems to be intentional bug in the way how color management turns off in Windows 10. Windows 7 works as expected.
If you select the Off no color adjustment, color management is not turned off ...
I even tried printfab printer driver, the output is similar, colors are washed out. Profile created has not only smaller gamut but jagged edges as result of poor linearization the printfab has done.
Many years ago I contacted printfab about custom linearization their were promising it even...
