[Publisher 2.3.0] Farbmanagement funktioniert nicht wie erwartet/Color management does not work as expected


Recommended Posts

1) Wenn man in den Einstellungen verschiedene Rendering Intents einstellt (perzeptiv, relativ farbmetrisch, mit bzw. ohne Schwarzpunktanpassung etc.), so ist das Ergebnis im ausgebenenen PDF (X-1a) immer eine Separation der platzierten RGB-Bilder mit dem perzeptiven Rendering Intent.
2) Spielt man dieselben Einstellungen als Softproof durch, so werden die verschiedenen Rendering Intents korrekt berücksichtigt.
3) Platzierte CMYK-Bilder werden unverändert ins PDF geschrieben. Allerdings: Wenn man in den Dokumenteinstellungen die Farbe ändert und die Option "umwandeln" benutzt, so wird ein CMYK-Bild so angezeigt, als ob es bei der Ausgabe in den Ausgabe-Farbraum des Dokuments umgewandelt wird - das ist aber nicht der Fall!

1) If you set different rendering intents in the settings (perceptual, relative colorimetric, with or without black point adjustment, etc.), the result in the output PDF (X-1a) is always a separation of the placed RGB images with the perceptual rendering Intent.
2) If you run the same settings as a soft proof, the different rendering intents are correctly taken into account.
3) Placed CMYK images are written to the PDF unchanged. However: If you change the color in the document settings and use the "convert" option, a CMYK image is displayed as if it were converted to the output color space of the document - but that is not the case!

Hi @Grizeto,

In honesty i'm a little confused by your provided info in regards to this problem, could you perhaps provide screenshots or a screen recording along with a sample document which demonstrate this colour conversion/render intent issue?

Many thanks!

Hi NathanC,

im Anhang findest Du ein PDF, in dem ich dokumentiert habe, was ich meine. Die verwendete Bilddatei schicke ich Dir auch mit.

Viele Grüße
