目的 考察物理发泡微球的油墨化及印刷效果。方法 将热膨胀型微胶囊按一定比例配制得到物理发泡油墨，采用丝网印刷的工艺，将发泡油墨转移至无纺布、铜版纸、铝箔纸这3种承印基材上。通过扫描电镜、厚度计和分光光度计分别测量发泡前后样品的形貌、厚度和色度变化。对印品发泡高度与承印基材之间的关系、发泡高度随温度的变化规律、油墨发泡前后的色彩特性进行研究。结果 印刷在无纺布的发泡体的高度较大，且套印2次后发泡体的厚度具有显著的变化。微球的最大发泡温度为150 ℃左右。青色油墨发泡前后的色差为14.49，发泡后的印品饱和度增加、明度值增加、色相基本不变。结论 微球发泡油墨可以在柔性基材上获得浮雕式的立体油墨图案和高饱和度的色彩效果。

The work aims to study deinking and printing effects of physical foaming microsphere. The physical foaming ink was prepared in proportion to thermally expandable microcapsules. The ink was transferred to three kinds of printing substrates, including non-woven fabric, coated paper and aluminized foil paper by screen printing. The shape, thickness and colour change of the sample before and after foaming were measured by scanning electron microscope, thickness meter and spectrophotometer. The relationship between the foaming height of printing products and printing substrates, the foaming height variation with the temperature, and the colour characteristics before or after ink foaming were investigated. The foam printed on the nonwoven fabric was relatively high. After overprinting twice, the thickness after foaming was significantly changed compared to that before the printing. The maximum foaming temperature of the microsphere was about 150 ℃. The colour difference of the cyan ink was 14.49 before and after foaming. The printing saturation and brightness value increased, but the hue was basically unchanged after foaming. The microsphere foaming ink can be printed on the flexible substrate and obtain an embossed three-dimensional ink pattern and a high-saturation colour effect.
