Triangle not only make inks to be sold under their own name but also make inks for printer manufacturers. How many printer manufacturers make ink? Who would you trust to make ink, a printer manufacturer or an ink manufacturer? Triangle inks are certified by many printhead manufacturers around the world such as Xaar in the UK. This means the Triangle inks will often have been developed for specific print heads before the printer manufacturers have even begun to build their printer. Given this level of integration it is simply ludicrous to imply that Triangle inks won't jet reliably through your print heads. On top of this, Triangle's ink train warranty, which is the most comprehensive in the industry will cover the costs of any repairs to the printers ink train should the damage be proven to have been caused by Triangle inks. All Triangle inks are also covered by Triangle's worldwide ink durability warranty.
