There are a few reasons why printed images look different from what you see on the screen:

1. Color modes: Screens use RGB (red, green and blue), while printers use CMYK (cyan, magenta, yellow and black), which can cause slight differences in color.

2. Screen brightness: Screens are backlit, making your images appear brighter and more vibrant than they’ll look on paper.

3. Resolution: Images that look sharp on a screen might print blurry if their resolution isn’t high enough.

4. Paper type: Matte or semi-glossy paper can also change how colors and contrast come across in print.
