This paper looks at digital infrared photography as a technique for identifying primary tattoos even if they have been covered up with additional tattoos. The study's goal was to look at a sufficient number of cover-up tattoos using infrared photography to enable the technique to be used more widely, and to attempt to elucidate the reasons for successful and unsuccessful infrared photography of primary tattoos through cover-up tattoos. Thirty-six tattoos were photographed in infrared along with colour control records. The results showed that primary tattoos could be visualized to some extent in 55.6 % of the cover-up tattoos and very well in 38.9%, this still left some 44.4% where the design of the primary tattoo could not be seen. The extent of visibility of underlying designs was found to depend on the ink colour, ink density and the extent to which the tattooist covered or incorporated the existing tattoo into the new design.
本文探讨了数字红外摄影技术，即便初次纹身已被后续纹身覆盖，该技术仍可用于识别初次纹身。本研究的目标是使用红外摄影对足够数量的遮盖纹身进行观察，以使该技术得到更广泛应用，并试图通过遮盖纹身来阐明初次纹身红外摄影成功与失败的原因。对36个纹身进行了红外拍摄，并记录了彩色对照图像。结果显示，在55.6%的遮盖纹身中，初次纹身能在一定程度上显现出来，在38.9%的纹身中显现效果非常好，仍有44.4%的纹身无法看到初次纹身的图案。研究发现，底层图案的可见程度取决于墨水颜色、墨水密度以及纹身师覆盖现有纹身或将其融入新设计的程度。
