I printed Ciba's in my personal darkroom for years, and still would if the materials were easily available. I started printing them in 1976, with all the accompanying masks, and the early prints show no fading. If the Cibas are fading I would question if they were washed properly at the end of the chemical steps or if all the chems were up to specs. As to the issue of polluting the water supply. I was told that the later chemicals neutralize the earlier chemicals. E.G. that the bleach neutralizes the developer and the fixer neutralizes the earlier two steps making them neutral as chemicals. They used to include neutralizing tablets to be place in the chems at the end of the process. I really like the Ciba/Ilfochrome process and liked the fact that each print was a "one off" print, unlike prints from digital files which are, in theory, an exact duplicate of any earlier iterations. There is, in my opinion, a benefit in the fact that each successive print is unlike the earlier prints simply because, no matter how good and diligent you are, you will not ever do everything exactly the same each time. Now I'm in the position of either not getting prints from color film or having them scanned and making a Fuji Crystal Archive print. They look okay but I prefer the other process.
