Grey print comes out greenish
Hi
I am trying to print a fade from white to black on my sp540v. I cannot use the roland colour system for this, so I am using cmyk. I use different values of k, and I do not expect any other colours to be used in the print…
However, whatever I do comes out greenish, so the machine is getting some incorrect information from the file somehow.Anyone got any ideas? And that is BEFORE laminating ,which will make it go greener still.
Using Illustrator and versaworks by the way…

If it’s only black and white, try using "Density Control Only" (?on the Quality" tab?).

Ive never known what that setting meant before.
I have now got a long banner printing, but once that is done I will give it a go. Hmmm, interesting. I have done a few searches for density control only to see what comes up. From what I understand, this setting gives you complete control over the colours as to what you input in the design stage, without any colour "correction" from Roland…?
I am speculating here, but if you make a file in Illy, with a square coloured, say, cmyk 20, 30, 40, 50, you will get the ink actually firing at cmyk 20,30,40, and 50?
I Cannot wait to try it!

I’m not sure, to be honest.
I thought it used only black to print any file, I’ve used it to print what was meant to be BW images but not colour.
I’ll be interested to read what you discover.
Have fun playing, and good luck!

Simon,
It sounds like a profiling issue (unless it is something which has just started happening)
We had the same problem with our UV flatbed and had the experts from Fujifilm come in and do some new profiles.
I’m probably over simplifying it because they did various tests which were measured with some top end calibration gear but effectively the profile we had been using was putting too much yellow down. Not enough to see in other colours so much but it meant the greys always had a green tinge to them
I don’t know what control you’ve got but maybe you could try dropping the yellow a bit

Well its printing now, and it would appear that it is as I thought! Pure cmyk coming out of the nozzles! Ive never managed to get that before.
I threw in a few pantone colours for good measure, and they are closer than I have ever managed to get them. And the fade I was having trouble with has no green in it.
This setting is my new best friend
Thanks Richard!Simon.
