#Indesign cc 2015 vs 2017 iso
With my Acrobat this is not sRGB for RGB but ISO Coated v2 300% (ECI) for CMYK.
If I open Acrobat's superb Output Preview Acrobat's default Simulation Profile is used. It seems, that there is no ICC profile for sRGB attached with the PDF.

So what will happen if we output for PDF Interactive ?įirst thing we will notice if we open the PDF in Acrobat Pro/DC: To make a complex thing less complex, let's say it is all defined as sRGB. Provided: Transparency Blend Space is set to document RGB and the image's ICC RGB profile is the same as the document RGB. That a placed PhotoShop image that comes with a layer with opacity 50% would resemble the same image with a layer with opacity 100% where in InDesign the opacity is reduced to 50% with the Effects panel. If a transparent RGB gradient is stacked on it.ģ. A white object in the background would make no difference.Ģ. I think everybody will agree, that an object with a white backed gradient should look the same like an object that is not white backed with the same gradient fill. More and more output is created for non-print related stuff.įor now let me concentrate on PDF output that is viewed on the web. Why all this fuss about displaying RGB with InDesign? Most knowledgeable users would never consider building layered, transparent Photoshop images in CMYK mode. I think the conventional wisdom is to use CMYK as the blend space for any print project, but many of the modes produce unpleasant results because of the extra black channel and it's also at odds with the newer conventional wisdom that all images should be left as RGB. You would have to worry whether it will stay that way all the way to output, but if I flatten over in AcrobatPro the 100% black still holds.

But if you export to PDF/X-4 the 100%K value is maintained (a huge plus for using X4). InDesign's Sep Preview does show the default black converting to 4-color when the blend space is RGB-the numbers match what you would get exporting to flattened document CMYK (PDF/X-1a). In InDesign what settings give the most realistic preview of a CMYK document (no spots) But this is not my point here.Īlso see this thread where the problem came up recently: That is unavoidable with InDesign because InDesign is not supporting color separations with special Device-Link profiles. I agree with Rob, that we see a substantial bug with InDesign CC 2015 and CC 2017 when it comes to Transparency Blend Space set to Document RGB.įWIW: If you change from CMYK to RGB with the Blend Space text done with is shown as a mix of CMYK values and not as 100 K only. ISO-Coated-v2-300-RelativeColorMetric.csf The trick changing the Blend Space to RGB is not working anymore:Īll files can be downloaded from my Dropbox account:ĭropbox - BlendSpace-CMYK-vs-RGB-Different-InDesign-Versions.zipīlendSpace-CMYK-vs-RGB-Different-InDesign-Versions.zipīlendSpace-CMYK-PSD-Placed-CC-2015.4.1.inddīlendSpace-RGB-PSD-Placed-CC-2015.4.1.indd Row 2 and row 3 are showing different colors:Ĭompare that to the CS6 behavior.
InDesign CC 2015 ( also InDesign CC 2017 or CC 2017.1 Problem gone, because the Blend Space was switched to RGB: Transparency Blend Spaceset to Document RGB Transparency Blend Space set to Document CMYKĭifferent colors are showing when compared row 2 with row 3. InDesign CS6 ( also InDesign CC and CC 2014 Transparency Blend Space set to Document CMYK or set to Document RGB. Let's take the easiest effect you can apply: Reduced opacity.Īnd let's compare what is showing with Separation Preview turned on when comparing two different settings that mainly influence color fidelity: If they contain reduced opacity done with PhotoShop's Layer opacity feature vs the same effect done with inDesign's Effects panel?
How would placed RGB images react if an effect is applied by InDesign's Effects panel? Rob Day discovered a difference in behavior between two versions of InDesign when switching the transparency blend space from CMYK to RGB. It seems that something substantial has changed between InDesign CC 2014 and CC 2015 when it comes to using RGB images and RGB swatches with InDesign.
