I noticed a r1800 owner stating the problem he has with red printing using pigment ink. He needs to realize you CAN buy dye based ink for the r1800.. either a cis system or refillable ink tanks. Once done you definitely will need to make your own ICC's cuz the epson set is all based on Epsons own pigment ink and they are way off when using dye inks... or just print using no profiles at all...
