Did some repeated tests with PL6 print modul and Epson Print Layout
( colour management by PL / EPL, same paper profile ).
Two different test files in TIFF-format / ProPhoto had been exported from PL6 (DxO Wide Gamut WCS)
as JPEGs to 1-ProPhoto, 2-AdobeRGB, 3-DCI-P3 and 4-sRGB, w/o any colour correction.
- monitor set to Native (= combined AdobeRGB + DCI-P3) / 6500K
- monitor set to sRGB / 5900K (as well to 6500K)
Both programs display the differences between the colour profiles for the respective out-of-gamut colours, that the colour profile cannot hold.
In the first case, differences are clearly visible, while on the “sRGB” setting they are less obvious.
