Ink-jet images are often very large, so it is necessary to understand the truth that "I don't know the true face of Lushan Mountain, but toward which corner of the mountain". If the big picture still uses the resolution of printing, it will kill the computer.

In fact, there is no dead standard for the resolution of inkjet images. The following resolutions are used when I make inkjet images of different sizes, for reference only (the image area is square meters):

180m2 or more (resolution dpi: 1 1.25).

30- 180㎡(dpi:22.5)。

1-30m2 (resolution dpi:45).

Note: At present, most inkjet printers use 1 1.25DPI, 22.5DPI and 45DPI as output resolutions, so reasonable use of image resolution can speed up drawing.

Generally speaking, the photo resolution is 72DPI. If the image is too large (for example, the file size exceeds 400M when the actual size of the new image is displayed in PHOTOSHOP), the resolution can be appropriately reduced and the file can be controlled within 400 m. ..
