Why do photos printed by the Xiaomi Portable Photo Printer 1S have blue/black lines on the edges?
The color development principle of ZINK photo paper is based on a pulse mode of temperature and time controlled by the print head. The crystals in the paper form a stable structure and display specific colors when exposed to high heat, resulting in vibrant photos and images.
During the production process, the photo paper is cut into fixed 3-inch sizes, which can damage the chemical coating at the edges. As a result, when the print head applies heat, the damaged coating can be activated and cause the edges to appear black or blue. However, these edge lines are located on the sides and are extremely fine, so they do not affect the imaging quality.
