What's the difference between outdoor painting and indoor painting?

Photo printing can be seen everywhere. A perfect outdoor photo advertising screen, in addition to high-quality design, it is also very important to choose a high-quality printing company. Zhuhai Liqi specializes in photo printing and processing, and the 15 time-honored brand is trustworthy. So what's the difference between indoor and outdoor photography and inkjet printing? Which is more cost-effective? How should I choose? Zhuhai Liqi Advertising will answer these questions one by one and help you in production.

1. Portrait is different from inkjet. The widths of inkjet printers are usually 3.2 meters and 5 meters; The photo machine has a small frame, usually1.52m.. Different working environments: inkjet printers are mainly used for large-scale outdoor wall advertisements and signboards, which have strong weather resistance, that is, they can be waterproof and sun-proof, and will not fade and change color when placed outdoors for a long time. The photo machine mainly produces indoor stickers, exhibition boards, posters, posters and other indoor inkjet products, and the inkjet quality is relatively high.

2. Portrait is different from inkjet ink. Due to the different placement environments of inkjet products, inkjet printers and photo printers use different inks. The ink of inkjet printer is solvent-based ink, which is waterproof and shiny and does not change color after long-term storage. This photo machine uses water-based ink. No smell, not waterproof, need to be covered with film. The ink selected by Zhuhai Liqi UV printer is environmentally friendly, and there is no volatile VOC (organic volatile matter) component, which meets the requirements of environmental protection today, so there is no need to worry about harm to human body. After curing, the solid content of UV ink is close to 100%, and it contains almost no VOC (organic volatile compounds), that is, it will not emit volatile organic compounds, nor will it cause harmful environmental pollution, let alone worry about handling harmful flammable and explosive substances.

3. Portrait and inkjet output are different. The output medium of inkjet printer is usually inkjet cloth and PVC material on the surface of taxi sticker. The output medium of the photo printer is sprayed on the photographic paper adhesive PP and so on. Resolution: the resolution is not particularly high, because it hangs in a very high place. When photos are used indoors, they must have high resolution to ensure clarity. The basic parameters of photo machine and inkjet printer are also divided into thermal foaming nozzle and micro piezoelectric nozzle, because they are the most important parts of photo machine. Thermal foaming nozzle heats the nozzle to make ink foam and spray it on the printing medium, which will cause loss in the use of the nozzle. Need to be replaced regularly. Piezoelectric nozzle is to place many small piezoelectric ceramics near the nozzle of the print head of inkjet printer, and apply voltage to them in time by using the principle that they will deform under the action of voltage. The piezoelectric ceramics expand and contract, so that the ink in the nozzle is ejected and a pattern is formed on the surface of the output medium. This kind of nozzle is very expensive to manufacture.

4. The accuracy of taking pictures is different from that of drawing. The accuracy of a photo printer is generally 720DPI, and the index to describe the accuracy of an inkjet printer is generally dots per inch, that is, DPI, and the accuracy is determined by the nozzle. It is meaningful to develop with these technologies, and the accuracy of 600DPI to 720DPI is enough for the practical application of general advertising graphics and texts. Higher accuracy may just be the selling point of the product. In fact, many users are using 360DPI, 540DPI and 720DPI8PASS as the highest output modes. When you go up, you must use original consumables to reflect the subtle details. The improvement of printing quality is not so obvious, but the printing speed will be greatly reduced. More importantly, the nozzle loss is too large, which increases the unnecessary cost and is not worth the loss.

5. The speed of photographing is different from that of inkjet printing. The factors that affect the actual ink-jet speed are: pure ink-jet speed of equipment, RIP speed of software, data transmission speed, drying time and so on. Consumables cost: 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. Different brands and models of inkjet printers have different ink consumption per unit. It is estimated that the ink output per unit area of HP and ENCAD is larger than ROLAND and MIMAKI, but the price of compatible ink is slightly higher. Generally speaking, the use cost of Roland and Mimacchi is still lower than that of HP and ENCAD. Crucially, the quality of compatible ink is also the key to determine the rejection rate and nozzle loss. Zhuhai Liqi UV technology can achieve a linear speed of 400 meters per minute and 24-hour shift production. The daily output of painting is more than 6,000 square meters and the annual output is more than 2 million square meters, which can greatly improve production efficiency and save time for customers.

6. Portrait and inkjet are different colors. Portrait and ink painting are not the brighter the better. The quality of color depends on the color gamut size and the consistency of reproduction, that is, the 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, the inkjet effect is more gorgeous, and outdoor ink is darker and grayer. Zhuhai Liqi Advertising has continuously introduced high-end UV inkjet printing equipment and imported UV ink, which is environmentally friendly, healthy, ultra-high-precision, perfect and outstanding, that is, spray-drying, instantly available, realistic color reproduction, super sun-resistant and ultraviolet-resistant; The problems of fading, blistering and limited materials are fundamentally solved, and the outdoor sun resistance of UV painting can reach 3-5 years.

7. Portraits are different from painting for sun protection. The performance of photography and inkjet printing is mainly determined by the ink used, and the original ink of each manufacturer is basically not universal, so the anti-ultraviolet performance of different ink inkjet printing effects of each machine is different. Zhuhai Liqi Advertising also has the most advanced indoor inkjet model in China, with high printing resolution, exquisite and delicate color reproduction effect and bright picture (it can also achieve a certain waterproof effect after painting). Application scope of indoor photo inkjet: photo studio set inkjet, image digital inkjet, flag inkjet, colorful flag advertising inkjet, exhibition board advertising inkjet, photo inkjet production, indoor light box inkjet, etc.
