Cityinkexpress and Inkexpress here in the UK both use genuine Pigment ink in their compatibles.
Actually City Ink seem quite reasonable price wise, 100ml bottle of ink, ARC cartridge and a syringe all for £8.40 free shipping. Might give them a go.
Hi all..
I recently sent off for some compatible inks for my iX6850 printer and on their arrival I read the wording on the box very carefully.
The large black ink is labelled PGI-550XL and I assume the "PG" means it's a pigment based ink.
Just to be sure I messaged the supplier for confirmation...
