The industrial partner, GA International, has become a niche developer of label solutions for the biomedical (academic to commercial enterprises), automotive and fashion industries, making labels that withstand rigorous conditions such as extremely low temperatures to exposure to the most aggressive solvents. To expand in their current markets and to enter new ones, GA International has found it imperative to be more vertically oriented, with more control of the materials used in their label printing technologies. This project will seek to identify the ink/coating/substrate interactions that underly the performance of labels made by thermal transfer printing. For example, some suppliers provide coated substrates which in some cases, the printed ink will rub off easily while in other applications, the printed labels can withstand the harshest conditions of temperature/pressure or solvent. We will seek to thoroughly characterize model printed labels first, by observing the physical state of the coating via electron microscopy. Where permitted, chemical composition of the ink and coating will be done by NMR and infra-red spectroscopy (FTIR and attenuated total reflectance (ATR) for composition analysis/mapping. Using electron microscopy of cross-sections together with the surface analysis should provide clues as to how the ink interacts with the coating on the substrate. Then, model inks and coatings will be tested to verify the hypotheses formed from the analysis which will then position the partners to develop in-house inks and coatings that can be tailored to better serve existing customers while also pursuing new markets and applications.

工业合作伙伴GA International已成为生物医学（从学术到商业企业）、汽车和时尚行业标签解决方案的利基开发商，制造能够承受极端低温和暴露于最具侵蚀性溶剂等严苛条件的标签。 为了在当前市场中扩张并进入新的市场，GA International发现必须更加垂直导向，对标签印刷技术中使用的材料进行更多控制。 该项目将寻求确定油墨/涂层/基材的相互作用，根据热转移印刷标签的性能。例如，一些供应商提供涂覆的基材，在某些情况下，印刷的油墨将容易地擦去，而在其他应用中，印刷的标签可以承受最苛刻的温度/压力或溶剂条件。 我们将首先通过电子显微镜观察涂层的物理状态来彻底表征模型印刷标签。在允许的情况下，油墨和涂层的化学成分将通过NMR和红外光谱（FTIR和衰减全反射（ATR）进行成分分析/绘图。 使用电子显微镜的横截面连同表面分析应该提供线索，油墨如何与基板上的涂层相互作用。然后，将对模型油墨和涂料进行测试，以验证从分析中形成的假设，然后将合作伙伴定位为开发内部油墨和涂料，这些油墨和涂料可以量身定制，以更好地服务于现有客户，同时也追求新的市场和应用。
