Title: Colour cast
Post by: brucet on March 19, 2014, 11:54:13 PM
Had Qimage working just dandy until now! I have a commission for a museum. I'm about 75% way through printing the final prints and everything has been excellent. (QImage has made all the difference to my work flow. Thanks). BUT. Yep there's always a but!
But I went away for two weeks and came back to finish the printing. Some how something has changed and all my prints have a strong yellow cast to them. I did change ink tanks but they are genuine units and I've never had a problem before. (I've been changing tanks during the first 75% of the job with no issues).
So my question is. - What may have changed that I need to look at? Papers the same. Printers the same. I use the same QImage preset that I created. My editor hasn't changed. (I can overcome the yellow caste by desaturating the yellow in my editor but that's only a short term solution).

Any tips on what may have changed?

Thanks.

"Any tips on what may have changed?"

Your printer settings?

All that stuff about 'No Colour' and so on. There was a long thread a couple of days ago when Mike, Fred and Terry were helping a Canon printer owner untaffle a printer driver that seemed to have a mind of its own.

Nah. I was happily working with everything fine. Went away for two weeks. Turned everything back on. Followed my routine and the prints had a nice yellow 'glow' about them. As I said I can tone the yellow down in my editor but I want to know what may have caused the change.

Maybe I have a partially clogged head that is affecting the colour mix. When I get time tomorrow I'll do a head clean and see if there are any changes.

regards

Yes, that is the most common cause of a colour problem reported on this forum.
Not only do a head clean, print a nozzle check before and after the clean too.

I never got to do a head clean! I had other less important printing to do so just ran that. Then I tried again and problem solved. Seemed a clog was the issue and it resolved itself.

thanks

If I do not print at least once a week my R1900 almost always needs a head clean. 

I have for some time been just switching the printer on and off every three days, I think this gives it a mini head clean.  Seems to work.

I do a head clean right after I get my hair cut.  :D

Thank you Bruce for taking the extra time to come back here and tell everyone what cured the problem.
Everyone is better for that!
