Hi
Once upon a time I spent a long time trying to learn how PagePlus handles ICC profiles, and ran quite a few tests. It was soul-destroying.
But feel free to test it yourself.
Under Colour Management you specify Primary colour mode, which is CMYK for printing.
Internal RGB profile, which is your PC default profile. My Dell is sRGB.
Internal CMYK profile - good luck if you can find out, but after testing I ended up with Agfa swop which gave the best match.
Current monitor profile... I chose Adobe RGB after umpteen tests.
Then there is a tick box for "Proof for target printer profile" where you'll enter your printer's ICC profile. In my case it was FOGRA39. Logic says to tick this box.
Now you think it all makes sense and you're ready to go. But, ticking this box does alter the colours significantly, and I found not ticking it gave better results!
Furthermore...
Printing to my domestic Canon printer, allowing PagePlus to perform the RGB to CMYK conversion, actually gave me the best results of all. Specifying to alter the colour model to CMYK seriously distorted the colours for the worse.
To confuse things further, I exported to PDF X1a, with ICC profile box ticked, and the colours were awful. A simple flat Acrobat 5 export with nothing clever done gave the best results.
So now I ignore ICC profiles. Straight default colour settings and let the printer do what it does and I get consistently good results.
To confuse things further still... viewing the exported pdf on Microsoft Edge gives different colours to those on Google Chrome. So all the effort I placed in designing the perfect colour in PagePlus, which remained so when viewing in Edge, was changed in Chrome.
I was designing a banner, chose the colour in PagePlus/Edge, but the colours on the printed banner, from a commercial printer, match the Chrome version. So disappointing.
Colour is a tricky tricky business!
