In the production of digital textile printer printing, we often encounter large-scale and wide-width image design and printout. Therefore, designers should pay attention to the resolution setting when designing large-size advertising screens.
How should I set the resolution to the best for inkjet printing machine? First, we must understand the concept of image resolution. Image resolution refers to the amount of information stored in an image. It is the number of pixels in an image per inch. The unit of resolution is PPI (Pixels Per Inch), usually called: pixels per inch.
In graphic design, the resolution of an image is measured in PPIs, which together with the width and height of the image determine the image file size and image quality. For example, an image is 8 inches wide, 6 inches high, and has a resolution of 100PPI. If the size of the image file is kept unchanged, that is, the total number of pixels is unchanged, the resolution is reduced to 50PPI. In this case, the width of the image will become 16 inches and the height will become 12 inches.
The image resolution should be noted when making high-precision printer inkjet printers for printout in advertising inkjet design: the inkjet files are often straight and large. If the image design resolution is relatively large, then the computer can't stand it. For example, Photoshop can't exceed 30,000 pixels for drawing. The resolution of the inkjet photo is usually set to 72dpi. If the file is too large, for example, in the Photoshop menu, the image / image size shows that the actual size of the test article volume exceeds 400 trillion. You can appropriately reduce the resolution and control the file at Within 400 trillion. In this way, the design operation and the computer will be smoother when it is opened for browsing. It is not easy to cause the computer to operate slowly due to the large image file.
After designing the storage format requirements for digital inkjet printer images, many people will ask, why should the file format be saved when the designed image is printed out using a photo printer, etc.? In our commonly used photo machine printout RIP software, such as our common printing software, the formats that are usually supported are JPG, TIF and other formats. JPG files can be conveniently stored and previewed after the design is completed, as well as file transmission and software import and typesetting printout, and TIF format image files can not only reduce space, but also save file transmission bandwidth.
