What's the difference between inkjet and photo?

The difference between inkjet printing and photographing lies in the use of the machine:

Photo printers and inkjet printers are both large inkjet printers. According to the working principle, inkjet printers can be divided into solid inkjet and liquid inkjet, and the mainstream inkjet printer today is liquid inkjet printer.

1, with different formats: the format of inkjet printers is usually 3.2m, and that of photo printers is smaller, usually1.52m..

2. Different working environments: External inkjet printer is mainly used for large outdoor wall advertisements and signboards for outdoor inkjet operation. Its advantage is strong weather resistance, that is, it can be waterproof and sun-proof, and it will not fade and change color when placed outdoors for a long time.

3. Different inks: Ink-jet printers and photo printers use different inks due to the different placement environments of ink-jet products. The ink of inkjet printer is solvent-based ink, which has a strong pungent smell, is waterproof and shiny, and does not change color for a long time. This photo machine uses water-based ink. It has no smell, is not waterproof, and needs to be covered with film.

4. Different output media: The output media of inkjet printers are usually PVC materials and taxi stickers on the surface of inkjet cloth. The output medium of photo printer is adhesive PP sprayed on photo paper.

5, the resolution is different: inkjet does not need to be very high because it hangs at high resolution. When a photo is used indoors, it must have a higher resolution. Very clear.

6. Different output speeds: The factors that affect the actual ink-jet speed are: A: the pure ink-jet speed of the equipment, B: the RIP speed of the software, C: the data transmission speed, drying time, etc.

7. The cost of consumables is different: the direct cost of inkjet printing consists of ink, substrate, nozzle loss, film covering and rejection rate. Consumables cost usually only refers to the sum of the first four items. The unit ink consumption of different brands and models of inkjet printers is different, and the quality of compatible ink is also the key to determine the rejection rate and nozzle loss.

8. Different colors: The brighter the color, the better. The quality of color depends on the color gamut size and the consistency of reproduction (uniformity within the color gamut). The quality of color should be analyzed and judged in indoor and outdoor situations. Generally speaking, indoor ink has a large color gamut, and the inkjet effect is more gorgeous, while outdoor ink is darker and grayer.

9. Different outdoor ultraviolet resistance: This performance is mainly determined by the ink used. The original ink of each manufacturer is basically not universal, so the anti-ultraviolet performance of different ink injection effects of each machine is also different.

Maintenance skills of inkjet printer

The problem of nozzle blockage in the use of inkjet printers is mainly "prevention". The best way to keep the nozzle in the best working condition is to do some proper and effective daily maintenance for the nozzle every day, which will greatly reduce the possibility of nozzle blockage. Therefore, please read the following carefully and refer to the operation.

1. nozzle maintenance after installation and initial stage of equipment.

1. In order to make the nozzle enter the best operation state, please print as many pictures as possible within 1 ~ 2 days before the equipment officially begins to undertake production business. It is best to use all colors of CMYK 4, and add color bars of C, M, Y and K 4 on both sides of the picture to ensure that the four nozzles are always in ink-jet state.

2. When spraying, it is best to take out the moisturizing sponge from the rightmost cleaning station together with its bracket.

2. How to maintain the nozzle after the work is completed every day?

After finishing all the printing work every day, in order to keep the nozzle in the best working condition and avoid blocking the nozzle due to the volatilization of solvent ink, please maintain the nozzle and let the equipment stay overnight in the following ways.

1. Turn off the device.

2. Clean the moisturizing sponge with special cleaning liquid first, and then pour the cleaning liquid on the sponge to make it moist.

3. Move the machine head back to the rightmost cleaning station, so that the nozzle is closely combined with the moisturizing sponge.

4. Keep this state and let the equipment stay overnight.
