    This mostly happens when I enter the equirectangular view and try to level the image using "Straighten" option in the Equirectangular Projection. 

    This is expected when you straighten. You are essentially rotating the image, so all your pixels will fall in between other pixels. This is essentially what's happening: 

  2. @thomaso If you export with a PDF/X preset, then the PDF gets a colour intent which has a DeviceCMYK profile. When you export to non-PDF/X versions, the ICC profile used for the document gets added to shapes/text.It been logged with our developers as an improvement. Currently PDF export control over whether colour profiles is a single check-box, all or nothing. There maybe should be a way to include profiles for sourced images, but not for shape and text colours.

    However, I'm not sure why Acrobat won't show the overprint correctly. 

    I hope this makes more sense :) 

  3. Hi all,

    overprint works as expected but there's a catch with Acrobat. 

    Acrobat Object inspector will show that the overprint flag is set, but Acrobat will only preview the overprint if the colour does not have a colour profile.

    Use Output Preview in Acrobat, and make sure the Simulation profile is correct. If you preview Separations, then it will show without overprint. However, if you switch Preview to Colour warnings and check Show overprinting, then Acrobat does highlight the correct areas as overprinted. If you switch Preview to Object inspector, and click on an area intended to be overprinted, it will list all the colours at that point and the overprinted colour will say "Overprint=true". You will also see that the overprinted colour has a profile.

  4. Agreed, what he's trying to do is not really correct from a colour management point of view. The actual bug here is that regardless of the document colour space (CMYK or RGB), when we export, we get the following Blending Colour space:

    •  for PDF X4 we get Device CMYK (even for RGB documents)
    •  any other format that supports transparency we get sRGB IEC61966-2.1 (Even for CMYK documents)

    The blending colour space should be DeviceCMYK or DeviceRGB. Once that's sorted, his transparent document "should" match the one that's not transparent. We only care about the blending colour space at this point.

    Previewing/colour managing outside our app would be a user responsibility.
