After years of rapid development, digital printing has transitioned from growth to maturity in the industry. Generally, at this stage, the industry begins to stratify. Some high-quality enterprises choose high-quality digital printing machines, and some low-end Quality, choose some "high cost-effective" models, this article mainly discusses the following:
1. Physical and chemical detection index of fabric
In addition to the fabric itself, in the transfer process, the main physical and chemical indicators come from ink, which affects the sun exposure, dry / wet rubbing fastness, perspiration fastness, as well as azo, heavy metal content and other indicators. At present, low temperature disperse dyes are exposed to the sun The fastness is generally low, so making outdoor products will be a bit difficult, and there will be some problems in overseas transportation. In addition, there is a certain relationship between the physical and chemical detection index and the paper coating. Whether the paper coating has residual harmful substances on the fabric affects the detection index of the fabric. Therefore, the use of high-quality inks and paper is essential for digital printing production!
Second, the fineness of the pattern
Although digital printing is not subject to flowering and color restrictions, many beautiful designs also bring challenges to digital printing. There are two main aspects that affect the pattern accuracy: 1. The accuracy of the nozzle, the accuracy of the nozzle is generally suitable for high-quality order requirements below 5pl, and is variable ink drop printing; 2. The flatness of the printing platform / paper The transmission structure is mainly related to the continuous flatness of the paper on the printing platform. The unevenness of the paper will directly affect the printing accuracy and even cause the problem of color difference.
3. Color consistency
The consistency of color is related to the print head, ink, software, and single machine capacity. Different print heads have different color difference performance in printing, whether the ink is stable, whether it is consistent, and the density has a direct impact on the color. Different choices of rip software have different colors, color gradation changes, and color tracking. The color consistency of production is much higher than that of multi-machine production.
4. Continuous productivity
Digital printing orders generally have a pattern of one kilometer, whether ink is cut off during printing, whether the retractable system is stable, and whether it is neatly retracted and other factors are very important to the printing quality. Negative pressure ink supply, degassing device, these factors ensure printing to the greatest extent, the gas expansion shaft scheme has become one of the standard configurations of high-speed and stable industrial grade.
The high-quality production of digital printing is the need for industry upgrading and the direction of future development. Starting from the above four aspects, starting to improve the quality of digital printing processing will better occupy the digital printing market.
