The sustainable ink system was originally developed for large format inkjet printers. Because of the printing volume and hence the amount of ink used in this type of printing, alternatives to small inkjet cartridges need to be developed.
Some large format printers are equipped with large bags such as cartridges that contain 100-200ml of ink. This printer is a household name and this option is not available for small / home business users. You can also buy various constant ink supply system for your printer.
Another development is where ink is sent to a print head by a series of tubes. This often happens where piezo style print heads are used in professional large format printers. In this case, bulk ink is added to the reservoir and ink is drawn by capillary action to the print head.
They consist of each ink bottle, a tube that sends ink to a modified cartridge that sits on the print head in the same position as a normal cartridge, a support mechanism for the cartridge, and priming equipment to regulate the system so that the ink is sent to the print head.
The addition of sustainable ink systems now makes inkjet an economical technology for small businesses.
With a better continuous ink system, the process is clean and painless (compared to refilling your own cartridges) and allows printing to continue all the time. By observing the ink level in the ink bottle, additional ink is added simply by opening the ink bottle cap, refilling, then securing the lid again.
The limiting factor is now the printer duty cycle. The duty cycle is the number of pages per month that are designed to be handled by the printer. The continuous ink system quickly prints a duty cycle volume and then several.
