Locor photo machine requirements for image design, size and resolution
Piezoelectric photo machine can not only support large-size image output, but also far superior to traditional inkjet printers for printing accuracy, printing speed and image color effect, and it is more stable than inkjet printer. However, whether it is a piezoelectric photo machine with high-precision printout or an inkjet printer with low output accuracy, the design requirements, size and resolution of the image must meet the following design requirements before design.
1: Designing picture material to use large-size high-resolution large-pixel material, if it is vector material, because vector material does not have distortion when resizing in size, and small-size pixel low-resolution picture material If the size is greatly adjusted during design, the pixels will be reduced and the image will be distorted. It is not easy to be clear and blurred when the photo is printed, which affects the color and image effects.
2: Image DPI is the output requirement. Now the inkjet printer is required to use 11.25DPI, 22.5DPI and 45DPI as the output image. Therefore, the reasonable use of image resolution can speed up the drawing speed. The general situation requires 72DPI to 120DPI. If the output image DPI is higher, the image clarity will be better; however, if the image is too large (for example, if the new image in PHOTOSHOP shows the actual size, the file size exceeds 400M). ), you can properly reduce the resolution, control within 400M. Therefore, in the image design, the corresponding DPI setting can be output according to the required size of the design. If the image size is too large or the output file capacity is too large, the DPI setting can be reduced as needed.
3: When the image is designed and the image is output, the photo inkjet is uniformly used in the CMKY mode, and the RGB mode is prohibited. Because the photo machine or inkjet printer is mostly four-color inkjet, its color is completely different from the printing color. Of course, in the image design, according to the printing standard, the CMKY color mode is used. If the image is in RGB mode, you can use C and other related design software to convert the picture to CMYK mode. In addition, when the image is designed with a single color value, four color value adjustments, such as black values, can be performed. It is strictly forbidden to have a single black value in the inkjet and photo images. C, M, and Y colors must be added to form a mixed black. For example, big black 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.
4: Format requirements for image preservation. For current domestic brands of photo printers or inkjet printers, the RIP printing software used is mostly Monte, and the image format imported by Montes is commonly used in JPG\TIF format, but not supported. PDF, therefore, after the image design is completed, it is recommended to save the image as JPG or TIF format, which is convenient for Montevideo software import and layout printing.
The large-size advertising image is printed and printed on the high-precision photo machine. The perfect image effect and personalized creative design are more eye-catching. The effect of these advertisements and the city's seamlessness often makes consumers accept it very naturally. Advertising, this type of outdoor advertising display is more welcome.
