Photo machine for high precision inkjet printing
The photo machine realizes high-precision and high-quality image-printing and printing. Every user is pursuing it. When the merchant wants to make a product marketing through the form of the screen, he often chooses a high-performance photo machine to realize high-precision inkjet printing. A photo image is produced. In order to achieve customer satisfaction, ensure the quality of inkjet printing and inkjet printing, and at the same time receive the attention of the public, leaving a good impression, to pay attention to the accuracy of printing, color mode, waterproof sunscreen effect and image format, in order to make It meets the high requirements of modern advertising society for photo inkjet works. Because the high-precision inkjet photo image is made by the advertising screen, the visual impact is very strong. For example, some common food advertisements seem to be mouth watering. So what are the general requirements for the output of such inkjet photo images?
First, the color mode requirements
The CMKY mode is used uniformly for inkjet printing, and RGB mode is avoided as much as possible. Today's photo machines and inkjet printers are mostly four-color inkjet, and there are six colors of lighter C and M. If the color transition is made softer and more realistic. In the process of drawing, you should follow the printing standards, and the inkjet company will adjust the color of the picture and the sample close. The inkjet system uses CMYK four-color printing, and the color mode is also CMYK. The inkjet printing effect is generally due to printing. If the color and level are better, you can also use the RGB mode to print the image, get a wider color gamut, and print more vivid colors.
Second, the black part of the image requires
It is strictly forbidden to have a single black value in both inkjet and photo images. C, M, and Y colors must be added to form a mixed black. If it is big black, it can be made: C=50 M=50 Y=50 K=100. Especially when using the effect with PHOTOSHOP, pay attention to changing the black part to four-color black, otherwise there will be a cross section on the screen, which will affect the overall effect.
Third, the image accuracy
Outdoor advertising inkjet printing generally has a large amplitude, and the general resolution is 300dpi. The resolution of high quality equipment can reach 600dpi or 720dpi. Since most inkjet printing devices use the four-color principle, and the four color dots are not closely attached, all the analytical aspects are not too high, and the user can adopt a low-resolution image resolution solution, and the ratio is about four resolutions of one print dot.
Fourth, image design and image storage format requirements
Most of the RIP printing software of the photo machine supports TIFF and JPG image file formats, because these image file formats can save better colors and high-precision pixels. At the same time, these images are more convenient for designers to design and preview images, more intuitive and easier to color proof and correction.
The above is the introduction of the general requirements for high-precision inkjet photo images. In the outdoor HD inkjet output work, it is necessary to be treated with caution, in order to make the quality of outdoor advertising inkjet works satisfied by customers and get the recognition of consumers.
