What does airbrushing mean? With what equipment how to operate?

Airbrush The advertising production industry is actually an ancient industry, from the ancient production of store fronts to modern paint hand-painted signs, only with the development of high-tech so that the industry has a fundamental change, which is particularly manifested in the picture production. Paint hand-painted sign is completely manual operation, with many human factors, coupled with the paint itself performance limitations, the picture appears to be raw, rough, unattractive, quality can not be guaranteed. Compared with this, screen printing has made great progress, but because it involves plate making and other processes, the cost is too high for small quantities, the technology is still not up to par for large-format printing, and it is difficult to ensure the color uniformity and accuracy when backlighting. With the introduction of computer technology, the situation has changed greatly. Computer color inkjet printing machine makes full use of the advantages of electronics, control, chemical and other industries, so that the traditional production methods can not be compared with it, bright colors, long shelf life, not subject to format and batch limitations, the production of a variety of production methods, low cost, short production cycle. So the airbrush was launched in just a few years, has been popular everywhere. At present, the main manufacturers of foreign production of airbrush machine in the United States, Witte, Said company, Israel's Sai Angel, etc., the main domestic two kinds of Tiangong and the Royal Pen. Currently advertising companies use to imported equipment, domestic equipment, although the price, the industry's advantages, but in the performance of technology is still not as good as foreign products. Description of the airbrush generally have a few common concepts: width, single / double-sided, resolution, speed, color reproduction performance. Commonly used width of 5 meters, which is still on the market by the current width of the cloth-based decision, the machine width and then increase, there is no great practical significance. Single / double-sided refers to the double-sided spray painting can be completed at once, double-sided airbrush to complete the production of both sides, and single-sided airbrush to complete the double-sided spray is very troublesome, especially when the picture is fine, large size, the front and back of the bit will certainly appear different precision difference. Resolution for the description of the fine degree of the production of the screen, the current general use of 9-72dpi, the higher the resolution, the more fine picture production, the corresponding speed is also reduced, the general company has several resolutions of the printhead, according to the use of different situations. Speed is determined by the performance of the machine itself and the resolution used. Color reproduction performance is critical to the quality of the picture, the designer's intention can be realized from this decision. At present, the principle of the airbrush machine used in China is mainly point state airbrush and fog airbrush two kinds. The United States Said and Israel Sai angel using point spraying principle, Witte use fog principle. The former is suitable for the production of large images, the production of small images for close observation is not good. The difference between the two principles leads to the difference in the picture effect. First of all, fog airbrush production of the picture outline clear, especially in the production of lines, text, the most obvious performance. Secondly, fog airbrush to make the picture fuzzy, gray color, while the point of airbrush, although the color point in close observation is not soft, but distant observation of bright colors, and even some kind of three-dimensional sense. Closely related to color airbrushing are consumables, mainly including ink and cloth base. Generally speaking, liquid ink is a copy of the machine-specific supporting, each other can not be replaced, the cloth base has nothing to do with the machine. Currently the most commonly used Germany OCTLON, Korea Hanhua, etc.. The former maximum width of 5 meters, the latter 2.5 meters, 3.2 meters, but the latter price is much cheaper. In fact, the quality of these cloth itself is not much difference. General outdoor use for more than four years no problem, while the combination of spray painting ink and cloth can only guarantee three years without fading and color loss. In addition, in the actual production and use found that customers believe that the higher the resolution the better, in fact, this is a misunderstanding, the choice of resolution should be determined by the size of the screen and the actual installation, too high a resolution in the long-distance observation of the effect is not good. According to experience, the resolution of 18-36dpi general selection is more appropriate. Color spray painting is a new technology, but also the development of faster technology.

Post-production is an indispensable process in the airbrush industry, and plays an important role in the success or failure of the entire work and quality assurance. A fast, exquisite post-production, not only can make the work of icing on the cake, but also for the company to create greater economic benefits and corporate reputation. The concept of post-production is broad, basically all the design and production work after the post-production. For example: output, cutting, laminating, laminating, splicing and so on. Below, the post-production work to do a little explanation.

Output: image design and production is completed after the first work is output. In this process, the output image must be merged with all the layers (layers), generally need to be saved in .tif or .jpg format, if the image is made with Apple computers, the file must have an extension. For the image file point settings, the basic to maintain the output accuracy of 100 dpi up and down can be achieved, if the image to be output is a very large surface, the number of points can be appropriately reduced. This process has a few points to note: First of all, airbrush is different from printing, airbrush colors than the printing of bright, good-looking much. Therefore, the airbrush drawing must be set to RGB mode, rather than CMYK mode. Airbrush images are often very large, some imperfections in the print is not easy to detect the amplified output will become very obvious and exaggerated, and this point can not be found through a small sample, so the production of airbrush images in the production of the finished must be enlarged to 100% to double-check once. For a lot of text on the screen, more careful proofreading. And because there is no ready-made color scale in the airbrush output, in the grasp of the color bias should be based on experience, which is the purpose of playing a small sample.

Cutting: the screen output is complete, the machine will automatically cut the paper. For the size of the screen and the paper needs to be cut larger differences, to cut neatly. When we cut the film, we should also use scissors to walk along the marking line, because it will facilitate the work of the film in the laminating film, to better ensure the quality and success rate.

Laminating: "Laminating" is a "three-man" project, which requires a high degree of cooperation, a successful laminating work is "feeding", "pulling", "pulling", "pulling", "pulling", "pulling", "pulling", "pulling", "pulling", "pulling" and "pulling". A successful laminating work is the result of a high degree of coordination between "paper feed", "film pulling" and "rock". Specific operations are as follows; in the case of ensuring the appropriate width of the drawing, the length of the film should be appropriately lengthened a little (generally 20cm). The first is to adjust the knob of the roller, to the hand feel completely no resistance until the knob is slightly tight. The membrane is fed flat and spread to ensure that there is no side deviation and no extrusion in the process of membrane walking. Then, pull the membrane up, in the membrane is about to the head, the roller will be stabilized, pull the membrane to ensure that the end of the flush. At this time, the film puller down to protect the film at the same time "into the paper" people can enter the picture (one end of the picture should be flush), to ensure that the picture is spread out, both sides and the film parallel. When ready to order, you can let the "rock" people slowly shake, see no problem after you can move forward to the head at an even speed. In this process, the feeder should carefully check the picture whether there is hair and other things, try to clear away. After lamination, that is, into the "cut" work.

Laminated board: when the customer requires the addition of board, we will enter the next laminating process, and the table mounted commonly used two techniques, namely, adhesive backed paper type and spray 3M adhesive type. Compared with the two, the adhesive backing type will be more durable.

Adhesive backing type: the picture will be cut to the required size, flat on the board, the four sides aligned, the center with a heavy object or pressed by a person. Uncover one end of the adhesive backing about 10 centimeters of a strip, pasted to the display board, and then get the laminating machine, adjust the pressure to just through the display board. Will have been pasted on the screen end into, pull up the screen, by a person to draw out the backing paper, a person to push the display board to the head until.

Spray adhesive type: For the four sides of the standard display board (specifications such as: 120cm × 90cm, 90cm × 60cm), we are more convenient to apply the spray adhesive method. The board will be placed flat, the picture is placed flat on the board. In order to make the four sides of the picture better match the edges of the board, we first cut the picture along the two adjacent sides, and then take these two sides as the benchmark, align the edges of the board, fix the relative position of the picture and the board (the picture is pressed with a heavy object or pressed by other people), lift one side of the two sides of the board that have been aligned, and spray adhesive on the board thereafter. After half a minute, tug the sides of the screen tight and drop it at an even speed. At this time by a person with a scraper from the center of the picture to both sides of the picture to the picture to the picture completely with the board fit; the same practice lifting the other end of the picture, spray adhesive pressure, and finally with a paper cutter along the card strips of the board, the picture of the excess part of the cutting off, that is, the whole picture of the Hua framing finished.

Splicing: When the customer requires the picture is larger than the maximum size of the airbrush, we will separate the picture output, and then spliced together, in doing this splicing work, the picture design and production and output is a prerequisite, so each step should not be wrong. First of all, the splicing position of the picture should be clarified, in the end, who is on the top and who is on the bottom, which one will be bigger and which one will be smaller. In the output process, because the screen to be output is the same picture, so be sure to keep its color consistency and size accordingly (such as the width must be), to record the output of the set parameters to ensure that there is no error. In the process of splicing, the two pictures are first cut flush at the end where they are to meet. Then in a large enough plane to spread the picture, according to the correct relative position, put the picture, fixed with adhesive strips, lifting the upper part of the front of the picture to meet the part of the spray adhesive (to cover the picture is not sprayed adhesive) after the use of a scraper from the center of the two sides of the picture to be compacted and tightly. Turn up the other end of the upper picture, spray glue on the lower part of the picture, compaction, the picture will be spliced. Spliced picture must not be vertical seams rolled up, it is easy to produce wrinkles in the joints, this should be noted!
