Pansi Cave is another beautiful woman of Tang monks around many people question how there is no spider silk in the Pansi Cave, in fact, in the original work, it was until the time of turning the face that the spider essence spit silk wrapped the entire courtyard thousands of layers thick and penetrated the road. In order to fulfill the wish of the spider silk in the pan silk cave, the stamp buried the Easter egg.
The original artwork is painted with spider webs, but it feels very worn, right? Because for ordinary people, the presence of spider webs indicates poor hygiene and inaccessibility. Even after the spider spirit becomes a human, it does not like to have other underage spiders weaving webs on the side. And this spider web will be printed in the form of photofilm overprinting, which can be seen in fluorescence. In this way, in order to meet the requirements of ordinary people for the meaning of the pansi cave, it will not affect the picture.
This is the third time that a photofilm overprint has been used to print a stamp.
The printing of the "Eighth Congress of the All-China Philatelic Federation" is even more eye-catching, the cultural relics displayed in the original stamp content have been eroded by the years, the color is dull, the tone is mixed, but the Beijing Stamp Factory for the first time adopted the "six concave and one glue" secondary printing method, the six colors printed by the gravure printing machine in addition to black, the other five colors all use spot colors, and the white fluorescence that produces a wonderful lighting effect is printed with an offset press.
The stamp of "Mogao Caves" adopts shadow and rubber overprinting, and under the purple light, the edges show a stunning cave effect; coupled with the design of the lute-shaped perforation of the whole stamp, it adds a stronger ornamentality to the overall picture.
