在讨论黄鹤楼(Hard Xiangluo River)卷烟的小盒正面印刷鉴定时，我们需要注意真品的黄鹤楼图案是通过烫金的凹凸印刷技术实现的，这使得图案具有强烈的立体感和清晰的层次结构。相比之下，假冒产品则可能使用的是模仿的套印烫金工艺，这种工艺通常比较粗糙，边缘不整齐且有毛边，并且缺乏真正的立体效果。此外，假冒产品的“Xianqu Rouqing”印章的颜色也可能显得较淡或不够真实，这些都与正品的印刷工艺存在显著差异。以下是一些经过伪原创处理的段落：

In our discussion today, we will delve into the methods of identifying genuine Huanghelou (Hard Xiangluo River) cigarettes by examining their packaging’s frontal printing. One key aspect to look for is the embossed and debossed gold foil printing technique used on the authentic Huanghelou pattern. This advanced method creates a strong three-dimensional effect with distinct layers in the design. In contrast, counterfeit products might employ simulated offset gravure printing techniques that result in a flatter image lacking depth and clarity. The edges are often jagged and poorly defined, indicating an inferior craftsmanship compared to the original product. Additionally, the color saturation of the “Xianqu Rouqing” seal may be noticeably different from its counterpart found on genuine packs, further distinguishing them as imitations.
