There are many reasons that affect the size of ps file. As the previous person said, it may be related to the material, for example, the size of the material you pulled in is too large.
But it may also be related to your own settings when you create a new document: ps is an image realized by recording pixels and colors. . You can try to create two new files with the same size and resolution, one in rgb format and the other in cmyk format. In the lower left corner, you will find that cmyk takes up more memory than rgb (even if it is blank). The reason is very simple, that is, rgb has only three colors (red, green and blue), and each color is 255 levels. . And cmyk is four colors. Therefore, when ps records files, the cmyk combination of four colors is more complicated than rgb and takes up more space than RGB.
Similarly, the file resolution will greatly affect the size of psd. Construct two documents with the same parameters except resolution, such as two documents with 1000* 1000, one with a resolution of 72 and the other with a resolution of 300. 300 is much bigger than 72. Generally speaking, 72 is used for screen media or large-size inkjet printing. 300 is used for printing. For example, the picture of WeChat official account, or the UI of app, and some very large inkjet advertising cloth (the kind of inkjet advertisement that is blurred at close range), that is, 72. For book media such as magazines (which need to be printed, the printing is actually very fine, and you can see the pictures of magazines more finely than watching advertisements at the same distance), you need to use a resolution of 300. . You can choose different resolutions according to the situation (note that the units I say here are pixels).
If the material is optimized, if it is too big, you can drag the picture to ps separately, and then choose the image-image size, and scale it according to your actual file size requirements. After scaling, drag the picture directly from here to the other side of the work, and then close the ps file of the scaled picture (you can choose not to save it when closing, so that your original picture will not become smaller, and it will still be of a larger size for later use). If you drag some psd/ai files directly into your work, intelligent objects will be formed. If it is not just needed (for example, this part of the content will change at any time), I suggest saving those smart objects as pictures and then putting them in. You can choose File-Export-Export as PNG. The picture saved in this way will be much smaller than that saved directly. And the quality will not be significantly reduced (except for special high requirements).
2. Why are some PSD files dragged to PS for special cards?
The problem of the topic should be psd with too much original data. Obviously, many things are rasterized. It is reasonable to say that the file should be small, but the file is still stuck to the explosion as before. This psd will get stuck even if you drag an inner layer to a new layer at will. Computer configuration is one thing, but if psd itself is fine, it won't take up so many system resources. Put forward the following suggestions:
Baidu ps cleans up the original data program and can find the corresponding script. The correct file is a. js file. After downloading, put it on the desktop, and then select File-Script-Browse in the ps menu bar, then select the script to clean up the original data, and click OK.
After cleaning, this file can be saved in a magical second, because this file is likely to become even smaller than1000 mm.
