China has a long history of printing. Before Cai Lun invented paper in the first year of the Eastern Han Dynasty (105), stencil printing with negative lines was invented on silk fabrics at the end of the Spring and Autumn Period and the Warring States Period. Block printing was invented at the end of Sui Dynasty, the beginning of Tang Dynasty and the beginning of 7th century. Bi Sheng, a printing master in the Northern Song Dynasty, adopted movable type printing (104 1), which initiated a new era of movable type printing on paper in the printing history of our country. In the subsequent development of 1000, printing has undergone technological changes such as gravure printing and lithography.
I remember the ancient achievements of our great motherland displayed at the opening ceremony of the 2008 Olympic Games. How many people in China were proud of it at that moment! Be proud of it! We should not forget the history and the ancient working people who made great contributions to the civilization and progress of the motherland and the world.
Learning screen printing, we can take it as a hobby, personally feel the profoundness of ancient China culture and experience the wisdom of ancient working people. You can also undertake processing and earn some money.
It is best to pay tuition in the factory to learn screen printing. Those things that are purely training and free are generally not ideal. I suggest you go to Taobao to search for "screen printing technology" or "screen printing training" and find a factory. I heard that there is a silk screen printing factory in China that teaches very well.
