If you insert ps with different resolutions, will it affect the printing effect? Example: Is it effective to insert a 300 dpi recipe into a 72 dpi recipe?
Look at the proportion of your picture in the whole picture. If you drag the size of 72 to 300, it will be clear enough without magnification, and it will not be worse than 300. On the contrary, if you want to enlarge it to meet the requirements of the picture proportion, then no matter how big you print it, it will definitely not be as clear as 300.
