Solution Overview
Problem
Current commercial printing technologies face inefficiencies in variable data printing, particularly with ink jet systems, which are slower, costly, and prone to clogging, and require ongoing ink purchases, while also dealing with toxicity issues and the need for additional equipment for high-speed fixed data printing.
Innovation Solution
A method and system utilizing a laser to ablate portions of a printed publication based on variable data, allowing for high-speed, high-quality, and ink-free variable data printing integrated into a commercial printing press, enabling the addition or removal of data during the printing process without the need for ink jets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ink jet systems are used for variable data printing, then variable data can be printed, but the printing speed decreases and costs increase
Solution Approach 1:
The patent replaces ink jet mechanical systems with a digital imaging and offset printing system. The variable data is incorporated into the digital image file, which is then processed by the offset printing press without requiring physical ink jet heads, thereby maintaining high printing speed while achieving variable data output
Solution Approach 2:
The patent changes the parameter of data variability by using digital image processing techniques. Instead of physically changing ink jet parameters, the variable data is embedded in the digital file structure, allowing the same printing press to handle both fixed and variable data through software control rather than mechanical modification
2Adaptability or versatility
If ink jet systems are used for variable data printing, then variable data can be printed, but manufacturing costs increase due to ongoing ink purchases and equipment maintenance
Solution Approach 1:
The patent eliminates the need for ink jet systems by substituting them with a digital imaging approach integrated into offset printing. This removes ongoing costs associated with ink jet maintenance, ink purchases, and head replacement, as the variable data is applied through the existing offset printing process using traditional offset inks
Solution Approach 2:
The patent makes the offset printing press multi-functional by enabling it to handle both fixed data printing and variable data printing through digital image processing. This eliminates the need for separate ink jet equipment, reducing overall manufacturing costs while maintaining variable data capability
3Productivity
If traditional printing methods are used for fixed data, then high speed printing is achieved, but variable data cannot be printed without additional equipment
Solution Approach 1:
The patent merges the fixed data printing capability of offset presses with variable data printing capability through digital image processing. The variable data is integrated into the digital workflow, allowing both fixed and variable data to be printed on the same press without requiring separate ink jet systems or additional equipment
Solution Approach 2:
The patent replaces the need for separate ink jet systems with a digital imaging approach. The variable data is handled through software and digital file processing rather than additional mechanical printing equipment, maintaining the high speed of the offset press while adding variable data capability
4Adaptability or versatility
If ink jet systems are used for variable data printing, then variable data can be printed, but the system becomes more complex and requires additional equipment
Solution Approach 1:
The patent replaces complex ink jet systems with a simplified digital imaging approach integrated into the existing offset printing workflow. Variable data is handled through digital file processing rather than additional mechanical systems, reducing overall system complexity while maintaining variable data capability
Solution Approach 2:
The patent makes the existing offset printing press multi-functional by integrating digital image processing capabilities. This eliminates the need for separate ink jet equipment and reduces system complexity, as the same press handles both fixed and variable data through software control

Data Source
AI summary
Systems and methods for adding data to a printed publication are provided. One method includes receiving variable data and controlling an energy source to at least partially ablate the printed publication based on the variable data. The printed publication is printed on the substrate using the commercial printing press based on fixed data. Controlling the energy source to at least partially ablate the printed publication includes, after the printed publication has been printed on the substrate by the commercial printing press based on the fixed data, controlling the energy source to remove a portion of the printed publication based on the variable data.
