技术领域technical field
本发明属于3D打印领域，涉及3D打印的色彩管理技术，特别涉及纸基3D彩色打印的曲面测色图标及制作方法。The invention belongs to the field of 3D printing, and relates to a color management technology of 3D printing, in particular to a curved surface color measurement icon and a production method of paper-based 3D color printing.
背景技术Background technique
3D打印技术被赞誉为一种能够改变现代制造业的革命技术，在航空航天、机械、生物、文化、医学等领域的发展极具迅猛。自从麻省理工学院申请第一个单色3D粉末式喷墨打印发明专利以来，基于其他材料的3D打印工艺和设备也被大量开发，其中基于纸基的3D打印技术也逐渐发展起来。特别的，纸基3D彩色打印技术所具有的丰富的色彩再现性潜力和环保性，使其在文化创意领域极具产业化前景。3D printing technology is praised as a revolutionary technology that can change the modern manufacturing industry, and it is developing rapidly in the fields of aerospace, machinery, biology, culture, and medicine. Since MIT applied for the first monochrome 3D powder inkjet printing invention patent, 3D printing processes and equipment based on other materials have also been developed in large numbers, among which paper-based 3D printing technology has gradually developed. In particular, the rich color reproducibility potential and environmental protection of paper-based 3D color printing technology make it very promising for industrialization in the field of cultural creativity.
MATRIX系列纸基3D打印机是爱尔兰Mcor科技公司首先实现商业化的基于纸张叠加工艺的3D打印机。于2012年，具有1200万种打印颜色的Mcor Iris series在法国富兰克福展会发布，意味着纸基3D彩色打印技术又进了新台阶。目前，纸基3D打印技术由于速率局限吸引了大量的关注，在颜色管理方面还没有获得相应对待，但这也是其在文化创意领域特别是需要高精度色彩再现性细分行业产业化的第二大瓶颈。The MATRIX series of paper-based 3D printers is the first commercialized 3D printer based on the paper-based superposition process of Irish Mcor Technology Company. In 2012, the Mcor Iris series with 12 million printing colors was released at the Frankfurt Exhibition in France, which means that the paper-based 3D color printing technology has entered a new level. At present, paper-based 3D printing technology has attracted a lot of attention due to speed limitations, and has not received corresponding treatment in terms of color management. Big bottleneck.
现有纸基3D打印技术在色彩管理方面完全凭设计师或工艺师的感觉选择打印材料和颜料，对于没有相应经验的普通客户是一个极大挑战。同时由于不同设计师或工艺师对三维模型外观颜色的灵敏度不同，造成纸基3D彩色打印成品颜色一致性问题。而传统平面印刷色彩管理技术虽然有成熟的颜色检测模型和设备，但没有考虑视角和物理位置对三维模型颜色外貌的影响，因此常规平面测试板并不适应纸基3D彩色打印成品色彩检测和预测。In terms of color management, the existing paper-based 3D printing technology selects printing materials and pigments completely according to the designer or craftsman's feeling, which is a great challenge for ordinary customers without corresponding experience. At the same time, due to the different sensitivity of different designers or craftsmen to the appearance color of the 3D model, the color consistency of the paper-based 3D color printing product is caused. Although the traditional flat printing color management technology has mature color detection models and equipment, it does not consider the influence of viewing angle and physical position on the color appearance of the 3D model. Therefore, the conventional flat test board is not suitable for the color detection and prediction of paper-based 3D color printing products. .
