【摘要】：喷墨印刷是在喷墨打印技术基础上发展起来的,成为数字印刷系统不可或缺的组成部分,其特点是高速智能、非接触、材料适应性广和工艺环保。喷墨印刷在印刷这个范畴里面能够被普遍的使用,主要得益于其自身印刷速度的提升。近年来,随着科学技术的迅速发展,现代印刷工业对印刷品质量的要求日益严格,使得印刷行业的自动化程度日益提升,在印刷品的检测效率以及准确性方面做了更加严格的规定。传统的印品质量检测方法因其主观性强、效率低、成本高等缺陷,对于现代化工业生产的需求已经无法满足。基于喷墨印刷平台的二维码质量检测系统通过将数字图像处理技术、机器视觉等和印刷原理相结合来解决喷墨印刷中出现的印刷品质量问题,达到用户所要求的喷印精度来保证印刷品的品质。这是当代工业质量检测重要手段的一部分,具有较高的实用价值及重要的现实意义。论文介绍了整个二维码符号质量检测系统的软硬件设计与实现,重点研究了二维码符号等级的影响因素墨盒负压、喷头电压、纸张到喷头的距离、走纸速度等。对喷印后的成品使用线阵相机进行图像采集,使用USB3.0高速数据接口进行传输,在数据处理模块中进行二维码符号等级的分析,凭借国家标准GB/T23704-2009文件中提出的检测方式,测量并计算出与二维码符号质量相关七个参数的具体参数值,并按照国家标准对各检测参数进行等级评估之后,接着将检测结果输出,最后将结果反馈回喷墨印刷系统。其中,二维码符号等级的确定及其影响因素是整个研究的核心。
[Abstract]:Inkjet printing is developed on the basis of inkjet printing technology and has become an indispensable part of digital printing system. It is characterized by high speed intelligence non-contact wide adaptability of materials and environmental protection of technology. Inkjet printing can be widely used in the field of printing, mainly thanks to its own speed of printing. In recent years, with the rapid development of science and technology, the modern printing industry increasingly strict requirements for the quality of printing materials, so that the degree of automation of the printing industry is increasing. Stricter rules have been made on the detection efficiency and accuracy of printed matter. Because of its subjectivity, low efficiency, high cost and so on, the traditional method of printing quality testing can not meet the demand of modern industrial production. The QR code quality detection system based on inkjet printing platform combines digital image processing technology, machine vision and printing principles to solve the quality problems in ink jet printing. Achieve the printing accuracy required by the user to ensure the quality of printing. This is an important part of modern industrial quality testing, with high practical value and important practical significance. This paper introduces the design and implementation of software and hardware of the whole system for the quality detection of the QR symbol. The factors affecting the grade of the QR symbol are the negative pressure of ink cartridge, the voltage of spray head, the distance between paper and sprinkler, the speed of paper walking, etc. The finished product is collected by linear array camera, transmitted by USB3.0 high-speed data interface, and analyzed in the data processing module. By virtue of the detection method proposed in the national standard GB/T23704-2009 file, the image collection of the finished product after printing is carried out. After measuring and calculating the specific parameter values of seven parameters related to the quality of the two dimensional code symbol, and evaluating the detection parameters according to the national standards, the test results are output and the results are fed back to the inkjet printing system at last. Among them, the determination of two-dimensional code symbol level and its influencing factors are the core of the whole study.
