It takes three to five days to complete the typesetting of pen-net papers. Typesetting is a necessary stage for the publication of every periodical. At this stage, the published articles have long been confirmed, strictly examined by three reviewers and three proofreaders, and revised by the author. There is nothing wrong with the article. As for the time required for periodical typesetting, it varies from publication to publication. Some magazines may be more efficient, and in the absence of holidays, typesetting may be faster, otherwise it will be slower, and the author needs to wait patiently when typesetting.
