Printing from Writer has colour discrepancies

[Trav78]

Having run out of black ink I printed a letter having changed the text to Dark Blue 4. However this generated a letter in orange text from my HP Envy 5000 printer.

Doing the same think in Word resulted in the correct colour text, so would appear not to be the printer.

So I ran a test 5 lines of text one in red, blue, yellow, green and Dark Blue 4.

The first 4 lines printed as expected in the matching colours, DB4 once again printed in Orange.

I’m slightly baffled and wondering if there is an explantion for this ?

You really saved the Dark Blue 4-colored LibreOffice text in a .docx Dokument, opened the resulting document with Word, printed from Word and you get Dark Blue 4 colored output? (Hard to believe).

Well no, I created a document in word which I cut and pasted the text into and then checked /set the colours. It did paste in with the correct colours though.

Trav78,

To print dark colours usually black is the main component. Not expected that in Dark Blue 4, cyan and yellow (instead of cyan and magenta) be the auxiliary components. Not obvious to everyone that printers use cyan, magenta, yellow and black (not red, blue, green) ink.

To momentarily fill the gap, try to print a screen capture of the stardard pallete, to see the behavior in other colours, and choose an alternate one.

The only way I see to figure out that would be, to have the .docx document and the .odt document with the colorized text. Unzipping and checking their respective color styles could provide an explanation (and I’ll be slightly baffled too, if the color codes will be the same in both documents).

To LeroyG - thanks, and I’d deduced that lak of black ink was resulting in Dark Blue not being as dark as it should be, presumably Blue and black are mixed for that, but it was still blue when originating from a Word doc - not orange as from Writer.

To Opaque - I’ve redone my test, Word behaves as anticipated, there is not an exact (descriptive) match in colour codes, so using the lighter to darker blue palette in Word from the darkest to 4 steps lighter results in print of 4 lines the same blue - hence no black being introduced, but they are all blue.
The same test with Writer is quite different:
Dark Blue 1 yields what looks like standard blue, so far so good
Dark blue 2 is similar but has a hint of darness across the top the letters - trying to squeeze more black out I’d say, so also good
Dark Blue 3 is actually quite a good really dark blue - wish I’d used that in the first place.,
Dark Blue 4, as before yields dark orange with a darker top, so it seems that for Dark Blue 4 the mix is changing from using blue to using a mix of other colours, but with the lack of black it’s coming out dark orange.
It does seem odd that Dark Blue 4 should actually not simply be some blue and more black, but it would appear that is the case.

@Trav78,

I wonder if Word and Writer are using the same printer controller. Old printers that have black cartridge or colour cartridge (not both at the same time) make dark blue mixing cyan, magenta and some yellow.
