Print Server Form Data Synthesis for Variable Printing Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In variable printing, the repetitive synthesis of master and replacement data for each page leads to significant time consumption, hindering the performance of the printing process, especially when common data is used across multiple pages.
Innovation Solution
An image processing device and method that extracts common data used across multiple pages, prepares form data by synthesizing this extracted data, and then combines it with non-reusable data to generate page data for printing, reducing the number of synthesis processes required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If master data and replacement data are synthesized for each page in variable printing, then each page can be customized with specific data, but the data synthesis time increases significantly
Solution Approach 1:
The patent applies preliminary action by extracting and synthesizing common master data once before the actual page generation process. The extraction unit identifies objects used across multiple pages, and the form data preparation unit synthesizes this data in advance into a reusable form data structure. This preliminary synthesis eliminates the need to repeatedly combine master data with replacement data for each page, significantly reducing the time loss while maintaining full page customization capability through the subsequent combination with page-specific replacement data.
2Reliability
If the same master data is transmitted repeatedly to the printer for each page, then each page receives complete data for processing, but the data transfer time increases
Solution Approach 1:
The patent applies segmentation by dividing the data transmission process into two distinct segments: (1) transmitting master data and replacement data separately to the printer in advance, and (2) transmitting only the synthesized form data and page-specific replacement data during actual printing. This segmentation allows the printer to receive complete processing data while minimizing redundant transmissions, as the common master data is sent once and reused through the form data structure.
Solution Approach 2:
The patent applies preliminary action by performing data synthesis and preparation before the actual printing process. The extraction unit and form data preparation unit operate in advance to create optimized data structures, so that during printing, the printer receives pre-processed form data rather than raw master data that would require repeated synthesis. This preliminary processing ensures data completeness while reducing transfer time.
3Manufacturing precision
If data synthesis is performed for each page in variable printing, then each page data can be generated accurately, but the printing process performance deteriorates
Solution Approach 1:
The patent applies preliminary action by performing the complex data synthesis operation once in advance during the form data preparation stage, rather than repeatedly for each page. The extraction unit identifies common objects, and the form data preparation unit synthesizes them into a reusable structure. This preliminary synthesis maintains page data accuracy because the same synthesized form data is consistently applied to all pages, while dramatically improving productivity by eliminating repetitive synthesis operations.
Solution Approach 2:
The patent applies copying by creating a reusable form data structure that can be copied and applied to multiple pages. Instead of performing synthesis operations for each page, the system synthesizes master data once into form data that serves as a template or copyable structure for all pages. This copying approach ensures consistent and accurate page data generation while significantly reducing processing time, as the synthesized structure is reused rather than regenerated for each page.
Data Source
AI summary
A print server which functions as an image processing device extracts the reusable data of each object to be used on multiple pages within the file and prepares the form data by synthesizing the extracted reusable data. The print server prepares page data to be used for printing by synthesizing the prepared form data and the data of each object that is not contained in the form data.
