Ink vendors are likely to change inks any time without telling customers. This has happened to Alotofthings before, many times by the way. It just happened to Inkjetcarts.com for your order of Inktec black pigment ink. I think it will continue to be that way always for many vendors.ghwellsjr said:I just bought a 32 oz bottle of pigment ink from Precision Colors which supplies Image Specialists ink. Hobbicolors also has a very good reputation but they won't say who their supplier is which means they could switch at any time. That is the only reason I went with Precision Colors.
I once chatted with a vendor on the phone. I asked if they could tell me their source of ink. They claimed their ink was made in USA. The answer was quite interesting. They said if they were to tell customers their source of ink they essentially would be telling all their competitors where they got their inks from. And that would be suicidal for them. It would not take too long to have dozens of competitors selling the same products against them. Whoever is the biggest would win. I have never been able to find out who actually made the ink for that seller.
I have also found that the particular vendor has not surprised me in the quality of their inks. I can not tell if they have changed inks at all. But the quality of their inks has been consistent.
The point I am making is, it is unrealistic to expect any ink vendor to never change their ink. It makes more sense to expect vendors with good reputation to keep up the quality standard they are committed to the customers. It would be very disturbing for me to receive a dye based black ink when I order a pigment black ink.
