Sorry, but what is the problem? Can you elaborate?

I’m guessing the colors look different. Blue mostly.

Sorry, I won’t be near a Dorico-equipped computer for the next couple of weeks, and it’s not very useful to investigate this on my phone… Maybe someone else here can help?

Well now. It’s a matter of what colour space PDF and PNG are using. PNG uses 24 bit RGB or 32 bit RGBA.

Colour spaces supported in PDF are way complex.

I don’t think there is doco on what colour spaces are used in the Dorico print function.

Perhaps @dspreadbury will be able to enlighten.

But in a nutshell I would be surprised if colours come out the same for PDF and PNG. And would not be surprised if changes in Dorico 6.

As an aside, almost ALL music is printed in B&W, and using colour is problematic because you have many many colour-blind people in the population and I am always rather taken aback and shocked when I ask them about their completely diferent perception, or weakened perception, of colour.

Well here is all the version 6 manual has to say:

Dorico Pro specifies colors using the RGB color model, rather than the CMYK color model that is used by platesetters and other professional printing machines. If you have colored items in your layouts and your layouts are printed professionally, you must post-process the graphics files that are exported from Dorico Pro in another graphics application to convert the colors from RGB to CMYK.

And yet more, colour rendition depends on your monitor calibration and chosen colour space. sRGB for photography is more limited than RGB for print. And Adobe RGB is different again. And so is Display P3. Or HDR setings. Also, is your monitor calibrated with a tool?

But thinking about it for day now, I think it’s false to expect those two colour renders to be the same.-

When I design booklets in Affinity publisher, I can have a file that doesn’t change its appearance on screen, but changing the color space settings during export will result in drastically different prints. The exported digital files will look subtly different, too. I’ve learned that I need to try a couple of different options to see what gets me closest to the desired result.

If PNG and PDF are both using different color spaces, it’s a little wonder things are coming out differently.
