12-20 ml per sq meter (20 if doing an overprint) + cost of media. Printing a page of text uses a lot less.
As to carts , the ratio the carts are used in will depend on the rip etc , suffice it to say that cart usage is not constant. You will probably use far more magenta then cyan etc – obviously depends on what you print.
Essentially with it’s solvent conversion , one could probably use most aftermarket types of inks with the machine barring the most agressive solvent type. However I would imagine this would void all warrantees and none of your exisiting profiles will work and the savings are not worth the potential cost of new heads or pumps or tubing or increased maintenance. This is apart from the fact that an aftermarket ink might contain very hazardous solvents.
The carts are not refillable , actually they ARE , but not easily and you incur some risk. When the machine indicates a cart is empty , there is probably still 15-25ml in it. The ink is in a sealed bladder in the cart , the opening of the bladder where the cart goes into the machine is much like the rubber seal of a vial of stuff to be injected. You can insert a syringe with a tough needle in it and suck out the ink and transfer it to another cart. Its VERY messy ,you risk puncturing the bladder and worst of all , you can get air into it. We do it only if there is an emergency. If a cart indicates empty , and you dont have another and you need to finish a job , have a look at the tab that protrudes from the cart. As the cart empties , it protrudes more and activates a microswitch. You can take the cart out and snip off some of the tab , this will “fool” the machine that a new cart is inserted and you will be able to complete the print as there is still a fair amount of ink left. dont run the cart till its empty , this will cause a LOT of problems.
