Printing images is the specialty of the T0548 because it is optimized for photo printers. This means that its inks output colours that have been created especially for making high quality photographs. Because of this, the cartridge evidently adds jet black colours into images, which are deep and sharp to create definite lines on the photographs. Because of the blacks in the images made with this ink, the photos look crisp and professionally developed. They mimic reality best, and are truer to the images that you find on screen. Along with creating beautiful photographs, this high quality ink can also be sent to you through speedy delivery. The 20ml cartridge is compatible with the Epson Stylus Photo R800 and the Epson Stylus Photo R1800.
