Cheap printer print quality will not be the same as the difference

How to save ink mode?

Many users have a habit of using the printer's ink-saving mode to print. Because it saves more supplies. Printer supplies standard test is based on a series of standards set by the International Organization for standardization, the ink coverage of 5% to calculate the number of printable pages of supplies. But in fact, sometimes we print more than 5% coverage, so our cartridges usually print a little less than the nominal print capacity.

Inking, saving mode is based on the principle: the normal mode of printing text, images, the basic will be filled with dots, and the provincial ink mode will not. So, in the provincial ink mode, the printer jet ink less, print quality will have a little loss, but the question is: how much of this loss, whether the impact of normal reading?

At the Hewlett-Packard World Congress, Hewlett-Packard ink expert Thom Brown from San Diego demonstrated the different print quality of HP's super-Whitney products and the saved-for-ink products in the saving mode. We see that the printing quality of Hewlett-Packard Province is still very bright color, and even for the Ink warehouse products appear a very serious bias, which should be related to the printer's ink-jet algorithm. In other words, HP's Super Province in the drive development, is to not affect normal reading as the starting point, and even for the ink bin is pure to reduce ink-jet volume, did not consider the user's reading experience.

Can the printed product withstand the test?

Many times we print out documents that are going to be kept for quite a long time, possibly for years or longer. But are the printed documents really going to stay that long? Thom Brown put HP's Super province and the documents that were printed in the ink warehouse into the water.

Here we see that, after being put into the water, the documents of the Super Province, although the paper is wet, but the document printing content is very strong, there is no change. And even supply ink warehouse products appear halo phenomenon.

What is the reason for this phenomenon? Hewlett-Packard's use of the black ink is pigment ink, pigment ink is not afraid of water, so the comparison can be seen in the province of super printing of the black part is very strong, and even for the ink warehouse due to the use of black dye ink, so there is a halo phenomenon, This is very detrimental to the long-term preservation of the document printing, especially in many areas, natural climate causes easy to cause documents damp.

It seems to be an old question: Is it better to paint ink or dye ink? In the document that requires print quality and durability, it is clear that pigment inks are preferable. Pigment ink is not afraid of water is not afraid of moisture, high water resistance, and then pigment ink polymer chemical stability is very good, can maintain the time of dozens of years, this is the dye ink can not match.

Of course, technically, HP's printers, including super-tech, print documents in standard mode and have the highest print quality in all inkjet printers, and this is HP's unique advantage. What is the advantage? is HP's PCL print language, to inkjet printers using the common print language algorithm of the laser printer, but also to the laser printer as clear and sharp document printing quality, which is the advantage of HP.
