The printer uses ZINK printing technology, and the printing effect can be slightly different compared to other printing technologies, such as inkjet or thermal sublimation. If you find that there is a significant color difference between the printed photo and the original image, you can try the following methods to help minimize the issue.
1. Make sure that the Xiaomi Home/Mi Home APP has been upgraded to the latest version;
2. Update the firmware of the Xiaomi Portable Photo Printer 1S to the latest version;
3. When changing the photo paper, make sure to put in the matching calibration card correctly. Improper placement or no calibration card will affect the print quality;
4. Confirm whether the resolution of the original image reaches 960x640 or higher, because the image resolution will directly affect the printing effect;
5. The photo paper should be used as soon as possible after opening, and avoid direct contact with the surface with your fingers to avoid affecting the print quality;
6. When the photo paper is not in use, please store it in a cool and dry environment to avoid the impact of high temperature and humidity.
This can help you reduce the color difference problem and ensure the print quality.
