The development of novel inkjet inks

2004年，PI承担了AHRC资助的项目“丝网印刷颜色作为喷墨技术发展的理论模型”（奖励号B/SG/AN5190/APN19134）。这次竞标旨在建立和扩展在以前的研究中开发和探索的方法。资金被要求支持CFPR和脉冲卷标签产品有限公司，油墨和清漆的标签印刷和包装行业的专业制造商之间的合作。此次合作将利用2004年的研究成果，利用喷墨技术的最新发展，使Pulse能够开发创新的UV固化油墨产品，用于商业印刷，从而使他们在该领域占据优势。今天，彩色印刷领域正变得越来越技术化，与传统的色彩应用方法在物理世界中的距离越来越远。艺术家混合和应用色彩的方式与彩色和彩色图像的数字再现有着根本的不同。艺术家的彩色印刷方法关注的是颜料的物理混合，然后作为色彩层应用，而色彩的数字再现依赖于计算色彩建模，为再现提供准确的数字数据。使用数字色彩的艺术家现在在一个日益技术化的环境中变得越来越有认知能力，这需要更多地了解不同的色彩空间，打印机硬件和纸张的特征以及一系列文件格式。Parraman（2004）的研究表明，从传统方法的角度出发，通过物理混合颜料和叠加颜色，可以形成对颜色更实用的认识和感性的理解。2004年，技术能力和色彩科学还没有准备好开发，部分原因是喷墨打印头的能力有限。喷墨打印技术和知识已经成熟，最近打印头技术和软件的改进增加了喷墨打印的潜力，可以在更广泛的材料上打印更广泛的油墨。先前的研究现在将允许使用一系列的着色剂，这些着色剂扩展了当前的工艺颜色集（与艺术家的颜色相匹配的定制调色板），专色（潘通）颜料和装饰油墨（金属，云母，光泽）以及新型着色剂（荧光和变色），可用于皮革，壁纸，金属卡片，塑料等材料。正如在工业印刷博览会上所展示的那样，从传统的丝网印刷和平版印刷市场向高速喷墨印刷的转变部分是由于UV固化油墨的发展，这种油墨对一系列材料具有更好的附着力，从而产生了多种新颖的印刷应用，包括：包装、纺织品和标签的装饰印刷。与2004年的研究结果相比，紫外光固化的这一发展为分层创造了更大的潜力。此外，它为打印机和油墨制造商开发UV固化油墨创造了进一步的商业开发潜力。Pulse公司生产UV固化水性油墨和清漆，用于柔印、网版和凸版印刷，希望从传统的色彩叠加的角度来解决彩色印刷问题，以创造二次色彩效果。该提案将超越半色调和工艺色彩- CMYK（青色，品红，黄色和黑色），转向开发定制颜料和装饰油墨，以获得新的色彩组合。该提案寻求与工业合作伙伴进行合作，以利用UV固化油墨和工业打印头的发展，结合以前的研究方法，打印更高粘度的油墨。结果应该导致新的方法印刷从从业者的角度更紧密地对准创意艺术和创意产业。

In 2004, the PI undertook an AHRC funded project entitled "Screenprinted colour as a theoretical model for the development of inkjet technology" (award number B/SG/AN5190/APN19134). This bid seeks to build upon and extend the methods developed and explored in the previous research. Funding is requested to support a collaboration between CFPR and Pulse Roll Label Products Ltd., a specialist manufacturer of inks and varnishes for the label printing and the packaging industries. The collaboration will use the results of the 2004 research by exploiting recent developments in inkjet technology to enable Pulse to develop innovative UV cure ink products for commercial print applications, thus giving them an advantage in the field. Today, the field of colour printing is becoming increasingly more technical and remote from traditional methods of the application of colour in the physical world. The way an artist mixes and applies colour is fundamentally different to the digital reproduction of colour and coloured images. An artist's approach to colour printing is concerned with the physical mixing of pigments that are then applied as layers of colour, whereas the digital reproduction of colour is reliant on computational colour modelling to provide accurate numerical data for reproduction. Artists using digital colour are now becoming cognisant in an increasingly technical environment that demands more understanding of different colour spaces, characterisation of printer hardware and paper and an array of file formats. The research developed by Parraman (2004) demonstrated that a more practical knowledge and perceptual understanding of colour can be formulated from the perspective of traditional methods by physically mixing colour pigments and overlayering colour. In 2004, the technological capabilities and colour science were not ready for exploitation, in part because of limitations in the capability of inkjet print heads. Inkjet printing technology and knowledge has matured, and recent improvements in print head technology and software have increased the potential to inkjet print a wider range of inks onto a wider variety of materials. The previous research will now allow the use of a range of colorants that expand the current process colour set (bespoke colour palettes that match artists colours) spot colours (Pantone) pigments and decorative inks (metallic, mica, gloss) and novel colorants (fluorescent and colour changing) onto materials including leather, wallpaper, metallic card, plastic.As demonstrated at industrial print expos, the shift from the traditional screenprint and lithography market to high-speed inkjet printing is partially due to developments in UV curable inks, which have better adhesion to a range of materials, resulting in a diversity of novel print applications, including: decorative printing for packaging, textiles and labelling. This development in UV curing creates greater potential for layering in relation to the findings of the 2004 research. Additionally it creates further potential for commercial exploitation for printer and ink manufacturers to develop UV curing inks. Pulse, who produce UV curable, water-based inks and varnishes for flexography (flexo), screen and letterpress printing, wish to address colour printing from the perspective of traditional overlayering of colour to create secondary colour effects. This proposal will move beyond halftoning and process colours - CMYK (Cyan, Magenta, Yellow and Black) towards the development of custom pigments and decorative inks to obtain new colour mixtures.This proposal seeks to undertake collaboration with an industrial partner in order to exploit developments in UV curable inks and industrial print heads printing higher viscosity inks combined with the previous research methodology. The results should lead to new methods for printing from a practitioner perspective aligned more closely to the creative arts and creative industries.
