What are the differences and characteristics between "raw propaganda" and "cooked propaganda" of paper in calligraphy works? How to tell? Please advise ~ thank you!

The biggest difference between raw propaganda and multi-purpose calligraphy freehand brushwork is that the transparency is not as high as that of cooked propaganda, and the strong water absorption will spread outward.

The cooked propaganda is mostly used for meticulous painting, and the paper is thin and transparent. For example, "cicada wing" is a kind of cooked propaganda, just like cicada wing, which shows that this paper is very thin and transparent. Cooked publicity is coated with alum, so that the pigment and a small amount of water will not be scattered.

Health promotion: thick, strong water absorption, poor transparency and stuffy voice.

Cooked publicity: thin, non-absorbent, high transparency and crisp sound.
