Cyan: Cyan is one of the three color channels that determine how accurately your labels reproduce blues, greens, and mixed tones. The GJIC5(C) uses Epson’s dye-based formula, which gives the C831 its characteristic brightness and color depth on coated label stock. If you run product labels, retail shelf tags, or food service labels where color vibrancy directly affects shelf appeal, keeping a spare cyan on hand is worth it. A single depleted cartridge mid-run means stopping production, and the C831 is not a printer you want sitting idle. Why order from Pacific Barcode: Pacific Barcode is an Epson ProFocus Platinum Partner, the highest tier in Epson’s authorized reseller program. That means you are buying genuine, factory-fresh ink directly from a dealer Epson has vetted for technical expertise and customer support. Your warranty stays intact and your ink is never counterfeit, refilled, or sitting in a warehouse for years before it ships.
