Epson T800500 UltraChrome PRO ink cartridge, Light Cyan, 700 ml

Light cyan is a diluted cyan that the printer uses in bright areas such as sky, water, light skin and pastel fills. If those tones were printed with full-strength cyan alone, individual ink dots would become visible. With light cyan the gradients are softer and the image looks more even, which is why an empty light cyan cartridge shows up in a photo straight away.

The 700 ml cartridge is intended for a large-format printer where ink goes fast. The bigger the cartridge, the less often work has to stop and the smaller the risk that an overnight job halts halfway. How many sheets or square metres one cartridge delivers is not stated by the manufacturer, as it depends on the image and print settings.

The manufacturer data lists the SureColor SC-P20000 and SureColor SC-P10000 as compatible printers. That is handy if a company runs both models, since one spare cartridge fits either of them. No other models appear on the list, so for any other printer check the cartridge code in its manual first.

Cyan and light cyan cartridges are easy to mix up because their names and codes look alike. The light cyan UltraChrome PRO cartridge is T800500, so compare it with the label on the old cartridge before ordering. It ships as a single cartridge, which means only the empty colour gets replaced and the rest stay in the printer.

Owners of a SureColor SC-P20000 or SC-P10000: photo studios, fine art printers, print shops and sign makers whose work contains plenty of pale blues and skin tones. Also IT or purchasing staff looking after several SureColor printers who want to keep a single spare cartridge that works in both models.
