The white works great - you need to shake the cartridges (and the printer tells you when to) because the ink's pigment will settle. The White even prints on Black vinyl. Fases even look better with the white ink to fill in.
Using the takeup - due to the fact the printer moves the media forward and back - the takeup cannot "backup" the media to be printed or cut.
How much speed do you lose? My rep told me it'll cut the speed at least in half, and speed is the reason I bought the XC in the first place.
When your printing with white you loose half speed. But when printing in 4 color without white its the same speed.
We've got an XJ640 so speed isn't the issue its the ability to print white.
Maybe I'm not asking right...
MY machine is set up as CMYK right now, so I have 2 of each color heads.. If I set the machine up to use white ink, I can still run 4 color jobs as normal, but only use the white as needed... right? If I set it up to use white, since there's less heads available for each color, won't I lose overall speed?
The XC 540 are 6 OR 4 color. The XC 540 can be a 6 color, 4 color, or 4 color with (2) white - not the XJ models. The XJ models are a 6 color or 4 color only-4 color is (CMYKMC) - you will gain some speed with it set up as a 4 color printer - pretty cool, Heh?
Yes, you can use the take up if you are printing only...I "assumed" you were cutting too. You can print flood white behind color, or print white with the color at the same time...or color/white/color onto clear for "two-way" window graphics (same view front and back). You really need a customer base that will pay for the white option, or print a lot of clear requiring white, otherwise (I believe) the 6 color is your best option and very best prints too. You do not have to print with the white, but you will use the white ink even if you dont print- the cartridges require you to pull them out to shake the ink inside, and use ink in the lines to keep it from settling in the lines (4 lines).
