Spray painting commonly used models and the function of commonly used materials

The use of spray paintings in the advertising industry has become more widespread, and more and more types of jet printers have adopted various advanced technologies. Customers may feel at a loss with so many choices. In fact, every machine has its own strengths, and customers can choose the most suitable model according to their actual situation.

The basic classification of the scope of spray painting: Indoor spray painting and outdoor spray painting.

Indoor spray painting commonly used models: HP, ENCAD NOVAJET, KEDAK maximum width of 1.52m, output accuracy of 300-2400dpi, using thermal ink-jet printing technology, ink through the film at the bottom of a thin film pores to the substrate on the substrate. The ink droplets are generated by a heat resister. When the ink film is heated to about 340 degrees Celsius, a steam bubble forms and is accurately ejected onto the paper. It combines a high number of nozzles and a high-frequency jet speed to make the droplets smaller and richer in color tone. Therefore, it is suitable for indoor spray paintings that are viewed at close quarters. Produce indoor advertising paintings, large poster posters, shop windows, paintings, light boxes, exhibition boards, etc. All of the above models can be competent. In addition to the advertising industry, spray painting can also be widely used in architecture, engineering, construction and mechanical design, as well as in geographic information systems (GIS), graphic images (GA) and other specialized fields. HP's ultra-fine line printing gives it special advantages in terms of its ability to fully meet the "rigorous" requirements of such print accuracy and print quality.

Outdoor spray commonly used models: Saite SCITEX, blue, smart, wit; Saite SCITEX: wide 3.2-5m, the highest precision 370dpi; blueboard blueboard: wide 5m, the most precise 150dpi; chic SALSA: wide 3.2m, the highest precision 300-600dpi; Witt VUTEK: wide 2-5m, the highest precision 360dpi.

Although the output accuracy of Sage Angel, Chic and Witt is not as high as the interior model, it can also be used as some of the indoor large-scale spray paintings. It is generally used for large-format paintings with widths exceeding the maximum width of the indoor sprayer. For example, curtain walls, stage backgrounds, etc. Some of the outdoor small square paintings with a viewing distance of less than two meters are also suitable for the above models. General body sticky note production process requirements are higher, due to the limitations of the body area, high precision requirements, in addition to waterproof sunscreen, but also able to withstand daily scrub without fading, the previous electrostatic photo can basically meet the requirements, but the biggest regret It is the color is not bright enough. Witt's spray paintings have better performance in terms of color and accuracy. The production of instant stickers on the body is higher than the static color saturation of images, but it is slightly inferior to the accuracy. Customers can make choices based on their own situation. The chic 600dpi accuracy is also impressive, but the print speed is more than double the speed of 300dpi. The blue plate is suitable for outdoor large-scale spray paintings. The viewing distance is more than two meters. The accuracy of 150dpi is sufficient. The blue plate machine wins bright colors and has a strong sense of hierarchy. In particular, the red color is particularly pure, but the green is slightly inferior.

Spray painting materials and functions:

Indoor materials include lights, photo papers, sticky notes, etc. Outdoor materials are divided into light cloths, front light cloths, instant stickers, etc. Lights and so-called back light cloths are used to make light boxes more. The paper is suitable for advertising posters, posters, paintings, etc. The name of the former lamp is the lighting in front of the painting, and the outdoor large-scale advertisements are mostly such materials. Sticky notes are just a layer more adhesive than photographic paper, which makes it easy to use spray paint on other materials. Indoor sticky notes are used to make display panels. Indoor sticky notes are used for car stickers.

The customer chooses the material, model and output accuracy, and it is time to move on to the next stage: production of inkjet documents. Most spray painting companies provide spray painting services, you can provide pictures, text and design drafts, or you can make your own computer files to spray painting company. If you are making your own files, you should pay attention to the following questions:

1. Use special effects with caution

Now the inkjet printer can accept many files made by software: photoshop, freehand, pagemake, coredraw, etc., but some special effects may be output according to the licensing machine, and jet printers may not be available. For example, the freehand 8.0 image transparency special effect, the inkjet printer can not output, so if the file made such special effects, we must communicate with the inkjet company in a timely manner, so as to avoid unnecessary losses. If you must use this class Special effects, it is recommended that you directly handle picture effects in photoshop, there will be no errors.

2. Indoor spray painting production accuracy

General requirements in the 80-100dpi, less than one square file accuracy requires 100dpi, more than a square, the larger the size, the file accuracy can be reduced accordingly. However, note that if the bitmap accuracy is less than 60dpi, the picture may appear jagged.

3 outdoor spray painting production accuracy

General requirements in the 24-35dpi, in principle, the smaller the smaller the precision, the larger the size, the accuracy can be reduced accordingly.

4. The basic requirements for inkjet file bitmaps:

In cmyk mode, the merge layer is background, delete the excess chae outside the four colors, and the file is saved in EPS or TIFF format. Of course, indoor and outdoor jet printers are not just a few of them. The author only briefly introduced several models currently used in the market, among which the opinions are for reference only. With the most reasonable price to buy the most suitable for their own services, in order to be in the commercial war in the wrong!
