Image specialist ink - special price

[fotofreek]

Sorry for the appearance of commercialism here, but I have to pass on a deal I just got for $24 US on a six color, four ounce each ink set (24 oz total) for bci-6 carts from Precision Color, a seller of Image Specialist inks. Usually $40. I emailed to ask if it was for real, and the answer was "Merry Christmas!"

Sorry if this is an inappropriate place for this post but I am new both to the forum and to inkjet technology.

I wonder is there a good information source on ink formulation and its requirements? web, book or otherwise

Many thanks
