Before spraying technology mountain now, the production of outdoor advertising means the original, personnel quality is low, the professional is not strong, so in the advertising industry accounted for the proportion of small, in the early 1990 s, spraying technology was introduced into China, advertising manager of high technical content and the picture is well-made, in recent years, large print industry development is rapid.

At present, the three most popular international mainstream print equipment: the United States "sweet" series of spray painting machine with its variety complete, stable performance, excellent quality and dominance in the printing industry, from single to double, a large prints from 2 m to 5 m width, the precision of from 360 to 600, from four to six color print and color, can basically meet the needs of all kinds of outdoor advertising frames: Israel "angel" and "Noel" came second, the market share of three. In order to improve the print accuracy, a new large print equipment through using piezoelectric nozzle, using solvent paint, ink products without coated guarantee two years not to mention in the outdoor color, printing speed faster and faster, the accuracy is higher and higher, the mainstream models from two years ago, 5 m width to the current 2.5 3.2 m.

Color print machine made full use of electronic, computer control, the advantages of chemical industry, the production of traditional methods cannot, by contrast, colorful, shelf life is long, wide and batch without limit, producing method diversification, low cost, short production cycle, so the print machine to launch a short years, has been popular in the world.

There are several commonly used concepts to describe a painting machine: Width ', single/double, resolution, speed, color reduction performance, such as commonly used for 5 m in length, this is decided by the duct width on the market at present, the machine width increase again, not much practical significance, single/double refers to double-sided printing can be completed once, advertising print double-sided printing machine to complete both the front and at the same time, and one print machine to complete double spray is very troublesome, especially fine picture, size is larger, both the front and back of the card will appear different precision of potential difference, the resolution for the fine degree of making images, now generally use 9-72 dpi, the higher the resolution, image made more sophisticated, Corresponding speed is lower, generally have several resolution nozzle, use according to different situations, the speed performance and use by the machine itself resolution to decide, color reduction performance is essential to the picture quality is sufficient, the designers intention can be fulfilled from this decision.

Spray painting machine principle of domestic use mainly have dot prints and mist spraying two kinds, the "DE" and "angel" Israel using dot print principle, use principle of fog "sweet", the former is suitable for making big picture, the close observation of small frames, the principle of the two differences lead to the difference of picture, first outline clear picture for fog plastics, especially in the production line, text clothing is the most obvious: second mist spraying blurred images, a gray color, when close observation and dot printing color point is not soft, but bright colours when long distance observation, there is even a stereo feeling.
