The products produced mainly include books, newspapers, advertisements, labels, instructions, packaging boxes, various certificates, bills, bank cards, etc., mostly paper products. However, the printers mentioned in job applications and recruitment information refer to general workers in printing factories, such as: packers, bookbinders, sorting, folding, collating, gluing boxes, handling, apprentices, quality inspection, proofreading, etc. Delivery, miscellaneous work, etc. are all types of work that can be mastered in a few days; the job recruitment information includes captain, master, deputy (second-hand), brewer, paper cutting, color mixing, plate making, printing room and other printing categories The type of work is for skilled technicians with work experience.
