This is our `full refillable conversion pack` for the Epson Pro 4000 which gives you 8x the refillable cartridges and 8x the 250ml ink refills. PLUS includes a FREE chip resetter which will also reset your maintenance tank chip to empty - NEVER buy another maintenance tank again! By using this kit you can benefit from extremely low ink costs ie as little as £14 plus VAT per 220ml when you buy our ink in 1000ml refills whilst maintaining the archival performance of the original Epson inks. Ink performance is matched to the original Epson inks and just as with the original inks they are all resin encapsulated pigment inks for vibrant long lasting images. True archival quality is assured as the inks have been independently certified by a leading UK test lab as being rated as `6` on the Blue Wool Scale meaning no visible fading for 85+ years (conditions apply).
