The preparation process comprises the following steps: (1) beating 40-50 parts of white raw silk by mass for 10-15 minutes; boiling the beaten white raw silk for 10-15 minutes to obtain archaistic cooked silk; (2) preparing pigment for colored drawing; adding 1-3 parts of cementing materials A by mass into 80-100 parts of plant pigments C1 by mass; stirring uniformly to obtain a pigment C2; (3) uniformly coating the archaistic cooked silk prepared by the step (1) by the pigment C2 obtained by the step (2) and naturally airing; (4) spraying 15-20 parts of a trace sediment protection agent W1 by mass on the archaistic cooked silk prepared by the step (3) and uniformly coating the archaistic cooked silk by 15-20 parts of a trace sediment protection agent W2 by using the same method after an organic solvent in the W1 evaporates; and (5) naturally airing to obtain an archaistic silk painting. According to the preparation process, the ancient cooked silk painting can be effectively imitated and a sample is provided for ageing research and protection work of the ancient silk painting.
