Description

Technical Field

[0002] In daily life, people often encounter many large-scale printed materials, such as wedding posters, maps, celebrity posters, and reproductions of calligraphy and paintings. Large-scale printed materials are typically printed using large-format printers, which print on rolls of paper. After printing, these rolls are cut to form large-scale printed materials. During the actual manufacturing process, large-scale printed materials may have blank spaces that are not discovered until after cutting. Alternatively, customers may request additional designs or content after cutting. In both cases, the cut large-scale printed materials must be discarded and redesigned and printed. Current large-format printer printing platforms are unable to control the flow of these cut large-scale printed materials. There is an urgent need for a printing platform that can reprint large-scale printed materials. Utility Model Content
