In industrial production, inkjet printers are widely used in various product identification. However, when inkjet printing is performed on curved products, the problem of inkjet deformation often occurs, which not only affects the appearance of the product, but may also affect the traceability and anti-counterfeiting of the product. and other functions have an impact. The products of Guangzhou inkjet printer manufacturers are no exception. The following will be a detailed analysis of the reasons why coding on curved surfaces is easy to deform from the aspects of the printer's own characteristics, surface characteristics, production environment and operation settings.
1. Characteristic factors of the printer itself
It is difficult to control the distance and angle between the nozzle and the curved surface
When designing ordinary coding equipment, it is usually optimized for flat products. When facing a curved surface, it is difficult to ensure that the distance and angle between the nozzle and the spraying surface are always the same. For example, for small-diameter hoses, the coding space is narrow, and the position of the nozzle needs to be adjusted to achieve normal coding. However, in actual operation, due to the undulating changes of the curved surface, the distance and angle between the nozzle and the curved surface will continue to fluctuate, causing the position and angle at which the ink droplets are ejected on the curved surface to change, thus deforming the code printing.
Limited coding accuracy and flexibility
Different materials of pipes and hoses have different requirements for accuracy and flexibility of coding equipment. The surface of plastic pipes is smooth, making it difficult for ordinary ink to adhere; the rubber hose is highly elastic, and it is easy to cause misalignment of the code printing due to deformation during the coding process; the surface of some metal pipes has been specially treated, and conventional coding processes may not be able to form clear and lasting marks. When the inkjet printer deals with these curved surfaces of different materials, its accuracy and flexibility may not meet the requirements, resulting in deformation of the inkjet code.
2. Surface characteristic factors
Complex surface shapes
Curved surfaces have various shapes, including regular cylindrical surfaces, conical surfaces, and irregular surfaces. The complex shape of the surface makes it difficult to predict the spread and adhesion of ink droplets after being sprayed onto the surface. For example, on a curved surface with a large curvature, ink droplets may be shifted due to gravity and surface tension, causing code printing to be deformed.
Surface material differences
Surfaces of different materials have different physical and chemical properties. The curved surface of plastic material may have poor adsorption to ink, causing blurred or deformed coding; the curved surface of metal material may have reflection, which affects the identification and positioning of the inkjet printer, resulting in inaccurate coding position.
3. Production environment factors
Temperature and humidity effects
Changes in temperature and humidity can affect the performance of the ink and the working status of the printer. Too high a temperature may cause the ink to evaporate too quickly, causing the ejection speed and direction of ink droplets to change; too high a humidity may cause the ink to condense at the nozzle head, affecting the quality of coding. When coding on a curved surface, changes in these environmental factors will further aggravate the degree of coding deformation.
Interference from dust and foreign matter
Dust and foreign matter may be present in the production environment, and they may adhere to curved surfaces or spray heads. The presence of dust and foreign matter will affect the normal ejection and attachment of ink droplets, resulting in problems such as breakpoints, blurring or deformation in the code printing.
4. Operation setting factors
Inreasonable coding parameter setting
Various parameters of the inkjet printer, such as printing speed, printing height, printing distance, etc., need to be adjusted according to actual production needs. When coding on a curved surface, if these parameters are not set reasonably, the coding will be deformed. For example, too fast printing speed may cause ink droplets to fail to adhere accurately to the curved surface; too high or too low printing height may affect the spray angle and spread range of ink droplets.
Lack of targeted debugging
For surface coding, the printer usually needs targeted debugging and optimization. However, in actual production, the operator may lack relevant experience and skills, and may not fully debug the inkjet printer, resulting in the problem of inkjet deformation that cannot be effectively solved.
summary
The products of Guangzhou inkjet printer manufacturers are prone to deformation when printing on curved surfaces, which is caused by a combination of factors. The inkjet printer itself has insufficient accuracy and flexibility when dealing with curved surfaces. The complex shape and material differences of the curved surfaces increase the difficulty of coding. Factors such as temperature, humidity, and dust in the production environment will also have an impact on the quality of coding. The unreasonable operation settings directly lead to the emergence of coding deformation. In order to solve this problem, manufacturers need to continuously improve the technology of the inkjet printer and improve their ability to adapt to curved surface coding; operators also need to strengthen the debugging and optimization of the inkjet printer and set reasonable coding parameters according to different surfaces and materials. to ensure the quality of the inkjet printer.
