Pre-Print Code Verification for Variable Data Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional variable data printing systems fail to detect abnormalities in the RIP process before printing, leading to waste of toner, ink, and paper, and reduced operational efficiency due to misprinting.
Innovation Solution
A printed matter examination apparatus and method that includes a master data acquiring unit, code information acquiring unit, and code information recognition unit to compare converted code information with unconverted code information, allowing for pre-printing misprinting examination by recognizing and correcting errors in the RIP process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional examination methods compare printed matter with reference data after printing, then printing can proceed without interruption, but misprinting errors cannot be detected early leading to waste of toner, ink, and paper
Solution Approach 1:
The patent applies preliminary action by examining code information in master data before printing occurs. The system extracts code information from the master data, recognizes it, and compares it with the original code information to detect abnormalities before toner, ink, or paper are consumed. This prevents misprinting waste by identifying errors in advance.
2Reliability
If code information examination is performed before printing, then misprinting can be prevented, but additional examination steps increase process complexity
Solution Approach 1:
The patent applies extraction by isolating and examining only the code information portions of the master data before printing. Rather than examining entire pages or images, the system extracts specific code information elements (such as barcodes, QR codes, or text data) and compares them with original code information. This targeted approach maintains high reliability while minimizing added complexity.
Solution Approach 2:
The patent introduces an intermediary examination process that acts as a mediator between data preparation and printing. The code information recognition and comparison unit serves as an intermediary step that validates data integrity without requiring changes to the core printing mechanism, thus maintaining simplicity while improving reliability.
3Speed
If conventional RIP processing is used without pre-printing examination, then the printing process is simple and fast, but abnormalities in RIP processing cannot be detected leading to erroneous image data being printed
Solution Approach 1:
The patent applies preliminary action by performing code information recognition and comparison before the RIP processing and printing stages. This early detection mechanism identifies abnormalities in master data that could lead to RIP errors, allowing correction before the time-consuming RIP processing and printing occur, thus maintaining speed while improving detection precision.

AI summary
A printed matter examination apparatus includes a master data acquiring unit configured to acquire master data that is data for printing and contains code information that is converted for printing; a code information acquiring unit configured to acquire unconverted code information; a code information recognition unit configured to recognize the converted code information from the acquired master data; and a code information examination unit configured to compare the converted code information recognized by the code information recognition unit with the acquired unconverted code information and determine that the converted code information is incorrect when the converted code information is not identical to the unconverted code information.
