problems to be solved

requirements for standards

the initial variable data printing is based on a special format, so there is no interchangeability between the front end and back end (RIP) of different suppliers of data and pages. In order to solve this problem, the organization dedicated to promoting digital printing technology issued the personalized flfil brush marking language standard in March 2000. The standard has been widely welcomed since its introduction. PPML based products were first exhibited at drupa exhibition in 2000. At present, the isolation building slowly swings on the rubber isolation layer and has entered the practical stage. Podi released version 1.5 of PPML standard in May, 2001. PPML language allows personalized software from different suppliers to communicate with machines from different printer manufacturers

data processing and data security

the data of personalized printing comes from the database, and the printing enterprises are not familiar with the technology of data processing, which is one of the challenges faced by traditional printing enterprises. First, the problems involved in data processing include changing data formats and transferring data from one system to another. In addition, the security of data also needs to be solved. The owner of the database cannot give up control over the customer database, and they do not want to submit the confidential database with commercial value to the printer. For the problem of data security, using PDF for soft proofing is a solution. The database owner can create, produce and proofing in his own organization if the agreement does not stipulate the experimental conditions. A complex variable data job can be printed remotely after the whole job is checked, sampled and signed by the user, that is, send PDF printing documents and specific parameter details to the printing workshop for printing Binding and packaging. In this way, printers are not directly close to pure databases, so the security of information has been protected to a certain extent

in the process of personalized printing, data processing is also needed to ensure accuracy, prevent spelling errors, and remove duplicate items. In addition, we need to analyze the data and decide how to combine the data with text, images and graphics to form a usable layout

verification and proofing problems

the waste of paper and the damage of printing sheets are inevitable in the traditional printing process. In the past, the usual practice in the printing industry was to print more. But for personalized printing, every page is different, so how to do this has become a problem. Manual inspection method can be adopted for verification of particularly small volume, but it cannot be adopted for personalized printing with large volume. Machine inspection and verification technology is required (this has been applied in the printing of bills and transaction documents). For some printing tasks, PDF antibacterial plastic can be used, or the proofing method will usher in a good development. For example, in variable printing and short version live printing, PDF format has proved to be a very useful proofing tool, which has many advantages, such as how to carry out pre press inspection, pre press confirmation, plate assembly confirmation, rip positioning confirmation, layout verification, etc. without starting printing

binding and post-processing requirements

the binding requirements of personalized prints are also different from traditional offset printing. For personalized printing, if a print is damaged during post-processing, it needs to be reprinted. Therefore, there should be no errors in binding. Some backup prints can be printed in advance for the bookbinding department to adjust the machine to avoid the final printed products becoming experimental products
