This test is a different story. Fading is severe and was obvious within days of the test beginning. Using both independent ink and paper - in this case Ko-Rec ink on Jessops Matt photo paper - results are very poor.
I suspect that most of the blame here lies with the ink, as this print looked pretty much like the Epson result when I printed it, and was fine for a few days, so if your need is for quick prints for a meeting, then this cost saving is worthwhile, but if your photos are important long term then, unfortunately, it’s best to pay more.
Few tests provide as conclusive an answer as this one. It would be great if inks costing less than half what the printer manufacturers charge, were just as good, but the results above, and many other tests I’ve made, including a more recent test with an independent pigment ink, all show the same results. Cheap inks fade - very quickly.
For that reason, my advice is, always stick with the manufacturer’s inks if your photographs are important to you. However, many independent photo papers are excellent, and if you want to keep costs down - don’t we all? - that’s where you can make savings without compromising on quality.
