Epson T552920-S 552 EcoTank Ink Combo Pack

The Epson T552920-S combo pack is the purpose-built ink supply for the EcoTank Photo ET-8500 and ET-8550 — two of the more capable consumer photo printers currently available in the supertank category. What separates this five-color set from standard four-color CMYK configurations is the inclusion of a dedicated Gray ink channel. That fifth color is what allows the ET-8500 and ET-8550 to render the subtle tonal transitions in monochrome prints without the color casts and posterization that plague printers trying to approximate gray from mixed CMY. For photographers who print their own black-and-white work, that Gray channel is the specification that actually matters.

The Claria ET Premium dye-based formulation is optimized specifically for these two printers — Epson builds its ICC profiles, maintenance cycles, and print head timing around it. The 70 mL EcoFit bottles use a physical keying system so each bottle can only enter its correct tank inlet, making refills clean and mistake-proof. For studios or home darkrooms running consistent print volumes, the supertank model dramatically reduces per-print cost relative to traditional cartridge systems, and the high-capacity bottles mean you're not constantly interrupting a print session to refill. Genuine Epson ink is the recommended path here — third-party alternatives introduce color accuracy variables that are difficult to manage without custom ICC profiling.
