At the end had the "HP C1825A Inkjet paper, bright white, A4, 90 g / m²" ahead. It was the most intense color printing with the best black value and "clearly" (most unverpixelten) printed image. We are (emotionalizes spoken) currently highly enthusiastic. Not least because we have such partly enormous differences in the printing qualities not expected and have admittedly been even just printed on the paper, which was of all by far the worst in the test (although even more expensive than the HP :-))).
We tested the prints by the way only in our inkjet printer "HP Officejet Pro X576dw e-All-in-One inkjet multifunction printer (A4, printer, scanner, copier, fax, Documentary proof, WLAN, USB, 1200x1200) CN598A # A80". Incidentally, a fantastic printer. He has proved, despite its great quality in the direct comparison sheet in a dramatic way, how important is the quality of the paper and the printer can not be so good, it does not help much if the paper does not "fit".
The only drawback to the HP paper the duplex printing has been proven since the 90g make it not to print a color intense image and simultaneously to prevent shine through. The latter was but - fair to mention - for ALL 80g-90g papers in the test ... they are just generally too thin to prevent show-through can. But not important as we do for us personally almost never duplex prints. But, if of interest ... for a great duplex printing at "almost" the same print quality (color same but minimal pixelated) has the paper "Avery 2566A inkjet printer paper A4, 100 g / m², 500 sheets, satin, bright white (Optimized protective packaging) "proved to be perfect. However, the latter is also twice as expensive. Therefore, we decided for the mass of our prints for minimally better print image of the HP paper for half the price and the Avery paper is now with the printer in the event that we should sometimes have an important duplex printing.
It should be noted that we read that different printers with different papers harmony, that I can confirm as I said our detailed test only our HP printer. But I would be surprised, if not, at least on all inkjet printers (laser printers have possibly again other "claims") may be confirmed the result as excellent. Anyway. Our experience is - like any here - of course, an individual ....
Have fun print!
