The length of your experience using this material is inadequate to come to definitive conclusions one way or another on matters of print longevity or their long-term impacts on print heads...
Baloney. Three printers run all day every day for over a year. "Inadequate" experience? It is HILARIOUS that you are claiming *I* do not have enough experience to post what I did when YOU have none at all... nil, zip, nada. Yet you did not hesitate to express an opinion based on fantasy instead of fact.
There is no inkhead monster under the bed kiddies. You can sleep soundly no matter what the FUD spreaders post.
My position is based on risk avoidance, not on any particular knowledge of the materials at hand
Bingo. Yet you have zero basis for establishing the fact there is a risk at all. No facts, none, nada, zip... again.
On top of all that, using 3rd party inks in an Epson professional printer voids the warranty for any related damage. That's "Clause 1" in the section of the Service Plan titled "What the Warranty Does not Cover"
Wrong again. Sigh. Don't believe everything you read from printer manufacturers. The use of third party ink cannot void your warranty in the US. This has been known for years, ever since the Magnuson-Moss warranty act was placed into law.
Just one reference (there are hundreds more):
The Magnuson-Moss Warranty Act states: “No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name” (15 U.S.C.A. 2302). While you may receive a warning that the [third party] ink you are using may void your warranty, this is not true. Unless the product will not function correctly without a product or service provided by the manufacturer, it is illegal for the manufacturer to suggest that use of [third party ink] cartridges will render your printer warranty void.
So how about ringing in with some facts, eh? Instead of running around screaming the sky is falling, just post some actual first hand negative experience with Inkjet Specialists ink and lets see the facts.
Next FUD spreader:
That's an amazing amount of printing - seems you should be making so much money that a car and house payments are no big deal anyway.
Yes, it is. Many liters a month. And yes, the materials we are providing are very profitable. And only poor people think money is of no concern and fortunately I am not poor... but thanks for your concern, quite touching really. Since you do not seem to be selling enough prints for ink costs to bother you, I will return your generous concern with the fervent hope your business picks up. Keep working at it and I am sure it will... eventually.
I assume your clients know what you are doing (sorry your year in the window test isn't very credible).
I don't care if you think it is credible or not. And my clients know exactly what I am doing... providing them with prints that WAY outlast their previous materials in some display environments considered very tough on prints.
