I am today using my printer as intended with CcMmYK inks. Though i am more and more mainly interested in black and white prints, and I love the samples I have seen from true black and white intended printers, especially considering metamerism. The dyes in the Epson is nice on my metallic lustre paper, but the more I print on the Canon 8300S with that paper, and also matte uncoated paper, I tend to prefer the latter. So I decided to convert the 1400 to a black and white printer, and keep printing the color on the canon instead.
So Farbenwerk sells 6 shades of black and white, where I can choose between carbon inks, or those blended with pigment so keep the warmth down, and also be able to choose K for glossy prints. And while I will start with 3 carbon inks (I know it might not be the best to only use three shades, but I hope it will suffice for me on my only-printing-for-myself-budget) I can later also either buy the glossy inks, or get the free K pigments from work. Hence the question before doing this. And thanks for your answers! Will get back to you later on.
