Pre press output and post press binding problem solving (Part 2)

how does the binding process calculate the completion of the task

answer: the quantity of processing tasks completed by the binding process (or workshop) is calculated in the order (1 order per 500 full sheets of paper) as the accounting unit, that is, multiply the total number of copies of a variety bound by the total number of pages of a book to obtain the total number of pages of the total number of copies, divide the total number of pages by the number of openings to obtain the total number of full sheets of paper, and then divide the total number of sheets by 500 full sheets of paper (1 order) to obtain the total number of orders of tasks completed by this variety, That is, the total quantity of paper used to process a batch of working materials (or a variety)

why should the bookbinding process be prepared before processing

answer: post press binding is a very complex processing process. In order to ensure the smooth connection between the upper and lower processes in the whole processing process, a series of production activities between the processes are carried out in an orderly manner, and the functions of various work, including process technology, personnel, equipment and so on, are scientifically and reasonably organized and coordinated, so that dozens of process flows can be smoothly produced, All preparations must be made before binding processing

what preparations should be made before binding

answer: generally, the following preparations need to be done: (1) undertake production tasks and assign processing tasks; (2) Determine the mode and method of processing technology; (3) Work estimation and material calculation; (4) According to the processing scheme, carry out normal plus the above work: (5) mantissa work; (6) Complete the calculation of the task

how to undertake production tasks

answer: the binding process is undertaken according to the technical conditions of the unit, equipment capacity and the requirements of the publishing unit

after undertaking the task, the production management department shall first carry out scientific and comprehensive process design according to the specifications, methods, methods and other requirements put forward by the publishing unit (or customer). For example, according to the different binding methods, the prepress and printing processes shall immediately communicate with the customer about the correct typesetting and printing methods, and formulate the correct processing scheme and distribute it to each process in the workshop

how to assign a processing task

answer: there are many types of machines, types of work, small processes and varieties of processing in the binding process. In order to ensure that this complex process can be carried out in an orderly manner and that the production task can be completed on schedule, the production scheduling meeting is usually used when assigning the processing task. First of all, the production scheduling director of the binding workshop analyzes the processing scheme, determines the process processing mode, method and processing steps according to the requirements, and then immediately holds the workshop production scheduling meeting to arrange the tasks through the four links of the scheduling meeting

how to determine the processing methods

answer: before processing, according to the requirements of the processing scheme, determine the processing methods according to the process sequence. For example, according to the loading method, opening number and materials of the processed books and periodicals, determine which ones are manually operated and which liquid additives are manufactured by using syringes to deposit materials at room temperature and which are operated by machines; According to the arrangement of the number of Posts and pages, whether it is necessary to bond and insert scattered pages; According to the binding method, what kind of material is used, what kind of binding form is used, whether it is wireless or lockwire, whether it is hardcover or paperback, and whether the hardcover is rounded; How to process to connect with each other, etc

how to process the binding process normally

answer: normal production can be carried out after the mode and method of processing technology are determined. Generally, starting from the first process of binding (pasting process), processing is carried out in sequence according to the process flow based on the processing scheme (or a sample book of unfinished products prepared in advance). After each process is completed, there must be clear numerical records, such as the total processing quantity, working hours, work quantities, materials, mantissa and whether there is a loss, etc. after the processing of a certain variety of books to be printed is completed After the numbers of varieties are complete and accurate, the processing scheme is completed, and then it needs to be filed as the basis for future processing

what is mantissa

answer: mantissa refers to the number of copies of a certain type of book that is not enough due to some reason, but the last number that needs to be remedied

what is the importance of doing the mantissa well

answer: the quality of mantissa work is not only related to the completion of each type of book processing task and the accuracy of the employment letter cycle, but also directly affects the reputation and capital turnover of the unit. Therefore, it is imperative to do a good job in mantissa work

how to eliminate mantissa? How to do the mantissa work well

answer: the best way to eliminate the mantissa is to start from the printed pages and strictly control the number of each process and the occurrence of waste products. When defective products and waste products occur in one process and are left to the next process as the mantissa, you should immediately put together the books or pages to make them qualified products, and complete the whole process together with a batch of books, so as to avoid delays and bad consequences
