The coding clarity of online coding printer is affected by many factors, including the model of printer, inkjet technology, ink quality, printing speed and surface characteristics of printed materials.
1. Type of inkjet technology
Piezoelectric inkjet technology: The ink is ejected by piezoelectric crystals to generate pressure, the ink droplets are uniform in size, and the coding clarity is high. It is suitable for high-resolution and high-definition coding needs.
Continuous inkjet technology (CIJ): The ink is ejected in a continuous flow, and the flight path of the ink droplets is controlled by an electric field. It is suitable for the coding needs of high-speed production lines, but the clarity is relatively low.
Drop-on-demand inkjet technology (DOD): Ink droplets are ejected only when needed, with high droplet accuracy, suitable for medium and high-resolution coding needs.
2. Printing resolution
Low resolution: Usually below 600dpi, suitable for simple letter and number coding, with average clarity.
Medium resolution: 600dpi to 1200dpi, suitable for most industrial coding needs, able to meet basic clarity and speed requirements.
High resolution: above 1200dpi, suitable for high-precision and high-definition coding needs, such as QR codes, barcodes and complex patterns.
3. Ink quality
Solvent-based ink: suitable for most materials, fast drying, but may be corrosive to some materials.
Water-based ink: environmentally friendly ink, suitable for paper and some plastic materials, slow drying, but high clarity.
UV curing ink: fast drying through ultraviolet curing, suitable for occasions with high clarity and durability requirements.
4. Surface characteristics of printed materials
Smooth surfaces: such as metal, glass and plastic, good ink adhesion and high coding clarity.
Rough surfaces: such as paper, cloth and some plastics, poor ink adhesion, need to use special ink or primer to improve clarity.
Porous surfaces: such as paper and wood, the ink may penetrate and affect the clarity, and the ink flow and drying time need to be controlled.
5. Balance between printing speed and clarity
High-speed printing: Usually at the expense of a certain clarity, it is suitable for the fast coding needs of large-scale production lines.
Low-speed printing: The printing speed is slower, the ink droplets are more uniform, and the clarity is higher. It is suitable for the coding of small batches or high-value products that require high clarity.
6. Environmental factors
Temperature and humidity: Suitable temperature and humidity help the ink to dry normally and maintain clarity.
Dust and pollution: Dust and pollutants in the environment may affect the quality of coding, and the production environment needs to be kept clean.
7. Equipment maintenance and calibration
Regular cleaning: Nozzle blockage or ink pipe contamination will affect the clarity of the coding, and regular cleaning and maintenance are required.
Calibration and adjustment: The position of the print head, inkjet pressure, and ink flow need to be calibrated regularly to ensure the stability and clarity of the coding.
In summary, the clarity of the online coding printer'scode is affected by many factors. By choosing the right inkjet technology, high-resolution printers, high-quality inks, and proper equipment maintenance and calibration, the clarity of the code can be significantly improved. In practical applications, the appropriate coding solution should be selected according to specific needs and material characteristics.
