I print a lot of pictures for my business. I purchased this ink and it lasted me almost an entire year of printing. Once the Ink went out, I went and purchased again and now a week later it is telling me that I need ink again. I am going to feel it out as maybe its a printer issue before I change this review. But, for ink to last a year..... THATS WHAT IM TALKING ABOUT!! Fyi printer is HP DESIGNJET 800

インクの排出口のフィルムが破れず、カートリッジの中にめり込んでしまった。 三本の内、二本が同じ症状になった。一つはカートリッジが分解してしまたった。 内部のインクタンク（ビニール袋）を止めているプラスチックの突起が破損して内部タンクが固定されなくなったのが原因のようです。

Two of the cartridges did not work, one did not register with the plotter right off the bat, the second one stopped being recognized after a day or two. Threw out the entire pack and bought authentic HP ink and they worked perfectly.

The last time I tried generic ink was 8 years ago. The ink 8 years ago was awful. It did not dry well and the colors did not match at all. Well, let me give you some feedback on these cartridges. By the way, I print full color prints, not CAD design prints. INK COLOR - Color was good and pretty much matched what is on my screen. DRY TIME - Ink dried very well. I did give it a day to lay around before inserting in tube. It is winter so we're going to find out this summer how the heat and humidity factors into the ink's ability dry and stay dry during shipment. PRINTHEAD CLOGGING - 28 posters in and so far and no issues. Lets keep in mind that I can print 400-600 or more posters using OEM ink with no issues so I'm still out on this. PRINTER READING CARTRIDGES - MY printer (not sure about yours) read the cartridges without issue. These cartridges are NOT identical to the HP OEM design/fit. During the printing process, I noticed that I had to seat one or two cartridges down in between prints. The print would end and I wouldn't hear the printer running. I found that during the printhead refill stage, a cartridge would pop out. No biggie. I just press down on the cartridges every so often. I didn't lose a poster during print so that was good. WILL I ORDER MORE - Just ordered two more sets WHAT WILL I DO IF PPRINTHEADS GO BAD TOO SOON - I will just buy another newer Epson or HP printer, use the expensive OEM ink, increase the price of my posters and move on. I will keep you posted.

Cartridges were correctly recognized with ink levels showing up correctly. Prints are good quality.
