This might be a stupid question but last year I had dramas with coloured ink getting into the wims white ink lines. This happened 4 times during the year( I now close the cymk lines overnight but it is way too late!!) so now I have a full bottle of light blue, full of light green, half of light brown and 1/4 of light pink. At $210 Australian a bottle this proved to be very costly. I was wondering if I mixed them to make a similar colour to a coloured ink could re use it there but the white ink is denser isn't it ? Also if I get a job that only wants one of the above colours could maybe put it through the white ink lines. Also are the nozzles in the head different sizes from the white to the colours ? Each morning I shake the bottles and there is usually a black film on top of all of them.Hope someone out there can help as it is a big waste
Cheers

Don't try mixing the White with the colours. It has Titanium Dioxide and you'll get settlign with the colours, not to mention throwing off the colour palettes big time.

My suggestions (and only if you want to take the risk with the old white ink)? Take on a big job that requires a white underbase design, but does actually have any white showing. In other words, a design that has white underbase and a dark colour layer completing covering that white underbase. You should be able to use up your white that way. That's what I did once when I had minor white ink/colour contamination.

Zenhjie has basically given you your only real option. Just make sure that the colors in the artwork are darker than the color of the mixed ink or it will not work. Because of how old the ink is, I think you are taking a risk. I would probably just chalk it up as an expensive learning lesson and move on. The risk of losing a print head and downtime on the printer is probably not worth the money you will be trying to save. But in the end, it is your call.

Best wishes no matter what your decision is.

I would agree with Mark. You are taking too big a chance with questionable ink. You might wind up possibly spending more money on a new printhead and dampers then what you could save using that ink. Not to mention your potential down time.

Yeah, white ink only has a good shelf life of around 6months? So if its a year old with contamination and separation, I wouldn't risk your print head.
