Can't see new colour profile window after upgrade to Pro+ 20.8.0.61047

[mwenz]

there is a difference in the PDF/x export when viewed on screen in adobe reader, between two of the cmyk profiles in xara selected at random, this difference is not there on the screen in xara - subtle but there in reader

the diifference is lost when they are reimported into xara

all this is with cmyk colour model and simulate print colours active

the xara representation is 'brighter than either of the PDFs in reader

Reader uses the exact same color management as Acrobat, so no worries there.

As regards color differences XDP+ vs. Reader. Without downloading the trial (or taking Bhav up on the offer to test the color management), I don't know what/why there is a change.

There are a couple possibilities as to how, or if, the pdf is including the profile. If a at the document level, then Acrobat/Reader will display using that profile. But if XDP+ is tagging elements and not embedding the profile at the document level, then one has to make sure the Output Preview panel is open AND that the correct output profile is displayed in the Simulation Profile drop down--which is something Reader does not do.

As for the initial set of screen shots, I get the exact same color representation with cmyk vector objects no matter the document cmyk color profile in Illustrator...else it is so subtle I cannot see a difference.

In general, in Photoshop, the difference is quite visible.
I certainly don't use crazy profiles. Yes, the difference between Coated Fogra 27 and 39 is hardly noticeable. But those standard profiles I use are very close to the printed result. This gives me more confidence.

This is CMYK photoshop file with two vector objects.

I can predict from having prepared hundreds of my stereograms for publication what colors are going to be more or less true to the RGB screen colors and which are not.

I did a quick test with four bright vector colors. Then I switched to Simulate Print Colors and did a screen capture.

I did a screen capture of the colors exported to PDF Commercial Printing, and finally as a CMYK TIFF.

Of the group the two closest are the PDF and Xara's CMYK TIFF.

Without knowing how Xara implemented the CM they used, I have near exhausted my input.

In general, you should not be using Relative Colormetric for your proof setup in PS if this job will be professionally printed. It's a good choice for home/prosumer print devices (esp. inkjets) but not if producing a pdf being (especially) offset printed or on calibrated professional print devices. As well, simulating paper color and Relative's therefore default of using simulated black also isn't a good thing in general. Depending on the type of job, even BPC may give false impression of what may actually print.

I would suggest using Perceptual in your PS proofing, with BPC unchecked.

Xara does need to have those settings exposed if they aren't, though.

I absolutely agree with Mike. I can't rely 100% on the screen, but good CMYK simulation and experience allows us to create graphics for printing without losing quality. Almost
Thanks Garry for the screenshots. We can see that the difference between Xara's print simulation and output images is huge. What am I actually talking about. I have nothing to add. This does not work.colorProfile.xar

Hi. Please can you check try disabling simulate print colors (window menu > show printer colors > screen colors ) and then checking if you see a difference on screen with CMYK colors when changing the profile? I'colorProfile.xar I've attached a file containing screen shots of several profiles with and without 'simulate print colors' enabled. A visual difference is seen on changing profiles when 'screen colors' is enabled.

Many thanks

ok check

I, for one, was doing it wrong - should not have had simulate print colours active, thanks

also you can see how in colour editor, athough the sliders are in the same place, the 'hue' of the magenta slider has definately shifted

Sorry, I already uninstall PRO+ and I can not check it now. But I believe you and realized what I did not correctly. Although I find your way not logical.

If Xara does not have full color management and works only in RGB space, the use of the „Simulate Print Color“ button is quite reasonable.
XDP cannot correctly interpret the CMYK files, especially from another software. Why then this quasi "automatic" preview?

[mwenz]

I had missed reading that the simulate print color action was being used.

That choice shouldn't be in the application any longer. It has no use now.
