Cheap inks are pretty good for most stuff, although the colours are questionable at times and longevity of the prints are not as good as they have a tendancy to fade much sooner than the canon/hp/epson ones.
Anything you want to put in an album I would just use an online service like Photobox. Although for day to day stuff, the 3rd party ones cannot be beaten.
Thats a trading fact, non genuine cartridges are weak in colour, I expected that, but these prints are superb, the only question is longevity, Ill suggest to the kids the get them laminated, like Serious said, lol we read the same mag.
