The way of the ink supply
1) We could have three ways of supplying the ink, one is using the standard ink cartridge in this way you have to change the ink cartridge as long as it is used out any color ink inside.
 
2) The second way is by using of the refill ink group which the advantage is help inject the same ink color when it is used out, it not only simply equals 14 units ink cartridge, but also can renew the lesser ink color, overcome the disadvantage, while one ink color is used of, all the cartridge would can’t be used. In this way it could make more print with the same inks. The disadvantage is you need to spend a little time to refill it but totally speaking it is save time as it is not easy to clog the ink head. this way is suitable for the print of discontinuous and little quantity printing. pls check the attachement to see the refill ink group photo.
 
3) The last way is the continuous supplying system. In this way the system could not need time to refill and chage the cartridge. but its disadvantage is you have to try print for 6-8 time when you stop print and start to print again in order to confirm the color is normal.
This kind of way suit for the continuous working and nonstop like if you print hundreds of T-shirt per day.
