Tips for using an inkjet printer

1. In the process of using the color inkjet box, pay attention to the balanced use of red, yellow, blue, and other colors. Do not print pictures that focus on one color only, because as long as one color is used up in the ink cartridge, even if other colors are not used up, the inkjet box cannot continue to be used. Generally speaking, the higher the resolution of the printed picture, the more ink will be used. Light colors consume less ink, and bright red or blue composite colors require more than one basic color synthesis, so more ink is consumed.

1. Do not switch the printer on and off frequently, because many types of printers will perform self-test procedures when they are powered on, which will consume ink. Try to print the materials that need to be printed together, which will also save ink.

1. If the print head of the integrated ink cartridge is dry and blocked, the following measures can be taken to improve it:

• Immerse the print head in warm water for about 10-20 minutes, and let the warm water dissolve the dry dye.

• Place the print head on several soft and dry paper towels, and let the paper towels slowly suck up the residual water and ink from the nozzle. Please do not wipe the print head hard. If the ink cartridge needs to be used immediately, you can put it back in the correct position in the printer. If it is not used for the time being, you can purchase a special print head protection seat for proper storage. The rubber pad in the protection seat can block the air and keep the nozzle moist for a long time.

• Never print again when the ink cartridge is short of ink. Printing will burn the nozzle.

Inkjet printer performance

Resolving power

DPI is an important standard to measure print quality in the industry. It represents the number of points per inch that an inkjet printer can print. In monochrome printing, the higher the DPI value, the better the printing effect. However, color printing is more complicated. Generally, the printing quality is affected by DPI value and color blending ability. As the black-and-white printing resolution and color printing resolution of general color inkjet printers may be different, you must pay attention to which resolution the merchant tells you and whether it is the highest resolution. Generally, at least 360dpi or above Inkjet Printer shall be selected.

Color harmony ability

For users who use color inkjet printers, the printer's color blending ability is a very important indicator. When printing color photos, traditional ink-jet printers will select a close combination of three basic colors to print if they encounter transition colors. Even if black is added, this combination can not exceed 16, and the expression ability of the color scale is not satisfactory.

To solve this problem, the early inkjet printers used the method of adjusting the density of the spray paint to express the color scale. However, for products with a color resolution of only about 300dpi at that time, the result of adjusting the density is that the transition color effect is very poor, and it looks like there will be a lot of spots. Color inkjet printers, on the one hand, make the printed points thinner by improving the printing density (resolution), to make the image more delicate; On the other hand, they have improved their technology in color blending. Common methods include increasing the number of colors, changing the size of ink droplets, and reducing the basic color concentration of ink cartridges. Among them, increasing the number of colors is the most effective. Usually, the five-color ink cartridge is used, plus the original black ink cartridge to form the so-called six-color printing. In this way, the number of color combinations obtained by permutation and combination is increased many times at once, and the effect is improved obviously.

The principle of changing the size of the ejected ink drops is to eject the standard size ink drops where the color concentration is high and to eject small ink drops where the color concentration is low, which also realizes more color levels. To reduce the color density of ink cartridges is to use the method of repeated inkjet to form more color levels in places with high color density.
