I. Print quality problems

1. Color deviation: The color printed may not match the expected color due to unstable quality of the ink itself, improper storage or compatibility issues with the printer.

2. Blocked nozzle: Large ink particles, more impurities or long-term non-use of the printer can easily cause nozzle blockage and affect the printing effect.

3. Blurred printing: Poor ink fluidity, improper printer settings and other reasons may cause the printed image to be blurred.

II. Ink performance problems

1. Poor adhesion: When printing on different materials, the ink may not have strong adhesion and may fall off easily.

2. Poor weather resistance: After a period of time, the printed pattern may fade, discolor and other problems, especially in direct sunlight, high temperature, humidity and other environments.

III. Compatibility issues

1. Incompatible with the printer: It may cause the printer to fail to work properly, error prompts, printing interruptions, etc.

2. Incompatible with the print medium: It is impossible to achieve good printing results on specific print media.
