RIP Time Estimation via PDF Resource State Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In printing systems, accurately predicting RIP time is challenging when the number of pages in sample data is small, as conventional methods alter the data structure, leading to inaccurate estimations.
Innovation Solution
A method that analyzes the original PDF file to create reuse information on resource states, then duplicates pages to maintain the same resource states, ensuring the new file's structure matches the actual data, allowing for accurate RIP time estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pages in sample data is increased to improve RIP time prediction accuracy, then measurement precision improves, but data structure accuracy deteriorates because conventional duplication methods alter resource states
Solution Approach 1:
The patent creates a copy of the original PDF file and systematically duplicates pages while preserving resource state information. By analyzing reuse information in the original file and applying it to the copied file, the method generates sample data that maintains identical resource states (shared or non-shared) to the actual data, enabling accurate RIP time prediction without distorting the data structure.
2Productivity
If conventional page duplication is performed to increase sample data size, then productivity improves, but manufacturing precision deteriorates due to changes in resource use states
Solution Approach 1:
The patent implements a feedback mechanism by analyzing the reuse information (shared or non-shared state) of resources in the original PDF file. This analysis results are used to control the page duplication process, ensuring that resources maintain their original states in the duplicated pages. The system automatically adjusts the duplication behavior based on the analyzed resource states, preventing structural distortion while efficiently generating sample data.
3Measurement precision
If the number of commands and figures in RIP calculation is increased to improve prediction accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent performs preliminary analysis of the original PDF file to extract reuse information about resources before the RIP time prediction process. By pre-identifying which resources are shared or non-shared and storing this information, the system avoids complex real-time analysis during prediction. This preliminary action simplifies the prediction system while enabling accurate RIP time estimation based on the pre-analyzed resource states and page duplication patterns.

AI summary
A file generation method for generating, based on an original file in a PDF format, a new file in a PDF format having a larger number of pages than the original file includes a reuse information creation step of creating, by taking the original file or a duplicate of the original file as one initial file and analyzing the initial file, reuse information for allowing specification of whether a use state of each resource is a shared state or a non-shared state, and a page duplication step of generating a page that constitutes the new file, by performing, based on the reuse information, duplication of a page in the initial file in such a way that the use state of each resource is same before duplication and after duplication.
