Hi Shangara, >From somewhat hazy memory, my recollection is that you save somewhere in the region of �260 by the end of your first set of bottles (even factoring in the CIS purchase)... This is calculated at about �570 to set up with CIS & 7*Epson 7600 carts (including bottle rack and UK postage)... though our calculations put the amount of usable ink at about 12ml per cart. (see http://www.mwords.co.uk/pages/cis/costFAQ.htm). >From then on, replacement cart sets would cost �282 (inc VAT and UK postage), compared to about �833 for equivalent numbers of Epson 2100 carts. Errr - just remembering that the Epson 7600 carts are only 110ml compared to our bottles at 125ml, which might mean you wish to factor down the savings a little based on that. Nevertheless, that looks like a cost saving > 30% after the first set of bottles and somewhere approaching 66% ongoing savings after that. Obviously the cost savings are attractive, but you must be sure that your ink usage will be high enough to justify it, and to make those savings in a reasonable period of time - our broad guide is a set of carts per month. I don't recall of any problems raised by our 'Ultrachrome + CIS' customers. This may reflect that the number of users is quite low compared to our 3rd party inks customer... By the way, I ran a test once on how many 10*8" Solid Black prints I could get out of a 2100 cartridge. The answer is about 14.5 (I regret I can not remember what the driver settings were)! Of course black is an unusual colour in that RGB 0,0,0 is very likely to result in close to 100% black output, and relatively tiny amounts of the other inks. 'Normal' pictures may have lower usages of ink to allow some paper-white to show through for the lighter colours (except for the R800 and any successor on gloss which will print 'gloss optimiser' where the lighter colours are!).
