Hallo zusammen

habe ein Problem beim .jpg direktexport aus dem indesign (Projekt als web mit px angelegt)

-> jpg export -> Qualität hoch / Formatmethode Standart / Auflösung 72 dpi / Farbraum RGB / farbprofil einbetten an

das Ergebnis weicht sehr stark von meinem workaraound ab
-> PDF export RGB 300dpi hres -> aufrastern im photoshop -> anschliesender jpg (web) export

Problem machen multiplizierte Flächen sowie Tranparenzen
(multiplizierte originalschatten / sowie Radialverläufe in grau - welche multipliziert sind)
Es ist dabei egal ob die Farben im indesign als CMYK oder RGB angelegt sind
auch die Änderung der Transparenzeinstellungen RGB/CMYK ändert nur minimal das Ergebnis
Farben sind beim direkexport eher flach und gräulich wohingegen beim workaraound das Ergebnis passt

Falls jemand eine Lösung bzw. einen Einstellungsfehler findet immer gerne her damit

Hallo boehmm84073849 ,

zeig das bitte mal als Gegenüberstellung in Screenshots.

Welches RGB hast Du in PhotoShop eingestellt?

Welches RGB hast Du in InDesign beim JPEG-Export eingestellt?

InDesign: Hast Du "Überdrucken simulieren" beim JPEG-Export an?

Gruß,
Uwe

Ausgangspunkt ist ein indeisgn web dokument
Problem ist die multiplizierter Radial Verlaufsfläche auf dem blauen Hintergrund
hab auch schon mit RGB bzw CMYK Trasparenz Einstellung experimentiert
bzw alle Farben in RGB - macht aber keine großen Unterschied ...
auch der Export aus einem indesign Druck Dokument
liefert die selben schlechten jpg Ergebnisse

Your Transparency Blend Space would have to be set to Document RGB. Also, make sure your Document Setup‘s Intent is set to Web that will convert all swatches to RGB. Set your document’s assigned RGB space to sRGB via Edt>Assign Profiles.

Hi Rob,

I think all that you mentioned is already the case.

The OP's JPEG Export options are showing sRGB as assigned RGB space.

I really wonder what's wrong here.

Did some tests and cannot see a difference with PNG and JPEG when using sRGB.

Regards,
Uwe

Thanks, I wasn’t sure about the translation. The ID export has the look of a CMYK blend space or a CMYK black used in the transparency effects. Also the JPEG export via PDF has no profile assigned

yes thats right what uwe is saying

all settings are made to rgb
the only problem is the transperency
of the radial circel which is multiplicated
to the blue box and the backingpicture
wich also has a fade to zero

maybe you can check out and test this file here
please check direct export to png vs jpg - or rgb pdf rastered to jpg
there you can see a big diffrenece
and sorry for bad english ...

Hi boehmm84073849 ,

thank you for providing the document.

Result:

Both, JPEG and PNG export is the same. The yellowish blue is visible.

JPEG opened in browser:

JPEG-in-Browser.PNG

PNG opened in browser:

PNG-in-Browser.PNG

Exported to PDF/X-4 with no color conversion and no downsampling, all color profiles included

The blue is not yellowish. All's ok.

PDF opened in Acrobat Pro DC:

PDF-X-4-exported-NoDownsampling-NoColorConversion.PNG

Uwe

only PDF (RGB) export with jpg conversion

has a fine and right optical result - in my eyes ...

and direct exports in Uwes post too  ...

Ah!

Tested a while with the JPEG Export settings.

Found a setting where the export will be alright.

I unchecked antialiasing.

( Kanten glätten aus! )

But that also means that one must do higher resolution to get a good export.

EDIT: Here the results:

Antialiasing unchecked:

JPEG-ExportSettings-Antialiasing-OFF.PNG

Result:

pw_recktangle_288x350_test_2-Antialiasing-OFF.jpg

With antialiasing checked:

JPEG-ExportSettings-Antialiasing-ON.PNG

Result:

That behavior must be a bug, that should get fixed.

FWIW: We can see the exact same issue with PNG Export and antialiasing turned on.

PNG-Export with antialiasing unchecked:

PNG-ExportSettings-Antialiasing-OFF.PNG

Result ok concerning the color:

pw_recktangle_288x350_test_2-Antialiasing-OFF.png

Wheras if we turn on antialiasing the same color issues happen:

PNG-ExportSettings-Antialiasing-ON.PNG

pw_recktangle_288x350_test_2-Antialiasing-ON.png

Tested with InDesign CC 2019 version 14.0.2.324 on Windows 10.

All original exported images, JPEG and PNGs, included inline here.

Uwe

Hi boehmm84073849 ,

another tip concerning PhotoShop's rendering algorithms for PDF vs EPS.

Better export flattened EPS files than PDFs. Why? The chance to see more subtle stitching artefacts that can come along with flattening transparency is higher with PDF renderings. On the positive side text rendering will turn out better.

At least that were my results once with PhotoShop CC. Don't know the exact version I did that test with.

EPS rendering and PDF rendering are using different algorithms with PhotoShop CC.

The algorithm for EPS rendering is the old one that you can see with e.g. PhotoShop CS4 or CS5.

Uwe

This is what I get out of CC2019 on OSX—don’t see the green shift. Maybe a German version bug?

Hm. A German version bug sounds very exotic.

Maybe we should compare our Color Management Settings that indeed will be different.

My document has sRGB assigned, the placed image also has sRGB assigned and showing in the Links panel. All document swatches are RGB including the [Black] swatch I used to recreate the shadow. The blend space is RGB.

The export was out of 14.02, but I get the same out of 13.1. I was thinking this could be the early 14.0 bug that turned off CM, but I don’t think you would get the green cast—it would just be less saturated. Getting a package with the problem file might help.

Hi Rob,

the OP's link to the document is all you need for testing.
All images are placed and embedded.

I tested with the embedded ones as well with linked ones ( I unembedded all images to a Links folder ).

No difference in results.

Still it's a mystery to me what exactly happens when antialiasing is turned on.

It really smells like a bug to me. Will test at the weekend if earlier versions of InDesign show the same issues.

Regards,
Uwe

Thanks, I missed the dropbox link.

Looks like JPEG export doesn’t like the Gradient Feather effect. There are two applied—the gray circle and there’s also one on the bottom JPEG. If I turn them both off, the color exports correctly:

There have been other discussions about problems with the JPEG export particularly when there are placed images. Here is an AppleScript that exports via PDF/X-4.

Now I tested the OP's document also with InDesign CS6.

Same issue found. So this is a long standing bug.

Alter Beitrag aber ich wollte meine Erkenntnisse teilen..

Es macht einen Unterschied ob man den Rahmen oder den Inhalt des Rahmens Multipliziert.

Ich glaube bei mir funktioniert es immer wenn ich den Inhalt des Rahmens multipliziere und dann den Haken bei "Füllmethode Isolieren" setze. Habe desöfteren das gleiche Problem, wenn ich Schatten als extra Datei im Hintergrund Multipliziere und dann auch noch mit weiche Kante verunstalte 😉

 

Isolate Blending = Füllmethode isolieren
