Whether you have to take 500 prints in a day or 5 prints a week, if you have a printer at home, at some point of time, you will need to refill the ink. One of the main reasons a lot of people have printer problems is because they either use the wring brand of ink or use a fake/cheaper version. If you have an Epson printer, it is imperative that you invest in only genuine Epson ink, because that will not only ensure great quality prints, but also a longer life for your printer. All ink cartridges comes with original pigment ink technology, which has been developed exclusively by Epson for professional photographers. The inks are designed to be cost effective without compromising on the print quality.
