Print Control Device for Dynamic Cutting Mark Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print control methods fail to accurately position cutting marks on printing paper, leading to potential overlap or loss of marks due to variable image and paper sizes, and reduced productivity when margins are not available for cutting marks.
Innovation Solution
A print control device and method that dynamically adjust the placement and visibility of cutting marks by varying the overcoat transfer methods and using tab areas in a heat-transfer type printing apparatus, allowing cutting marks to be printed regardless of image and paper size, and layout, using both color inks and overcoat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cutting marks are printed using conventional methods with fixed positioning relative to print target images, then the positioning is simple, but the cutting marks may run off the printing paper or overlap with adjacent target images when image or paper sizes vary
Solution Approach 1:
The patent implements dynamic positioning of cutting marks by making their positions variable based on actual image and paper dimensions. The print control device calculates optimal cutting mark positions by considering the number of images to be printed, their individual sizes, and the total paper size, thereby adapting the cutting mark placement dynamically rather than using fixed positions.
Solution Approach 2:
The patent changes the parameters of cutting mark positioning by introducing variable positioning based on image count and size parameters. The system adjusts cutting mark coordinates according to the specific printing configuration, transforming the static positioning parameter into a dynamic one that responds to changing printing conditions.
2Manufacturing precision
If margin area portions are provided around images to print cutting marks, then cutting marks can be printed, but the print target images are reduced leading to lower productivity
Solution Approach 1:
The patent utilizes the margin area dimension by positioning cutting marks in the white space surrounding images. By strategically placing cutting marks in available margin areas rather than requiring dedicated space, the system achieves accurate cutting mark placement without reducing the number of printable images on each sheet.
Solution Approach 2:
The patent applies different treatment to different regions of the page by placing cutting marks specifically in margin areas where they are needed, while preserving the full image areas for content. This localized approach ensures cutting marks are positioned accurately without uniformly reducing image sizes across the entire sheet.
3Ease of manufacture
If cutting marks are printed by providing non-transfer areas of overcoat, then the printing process is simplified, but the visibility of the cutting marks is lower and they are not visible unless the printed material is tilted
Solution Approach 1:
The patent enhances cutting mark visibility by printing them with color inks that create visible contrast against the background. Instead of relying solely on overcoat variations that are barely visible, the system uses colored cutting marks that can be easily seen under normal lighting conditions, thereby improving visibility while maintaining the simplicity of the printing process.
4Manufacturing precision
If the size of print target images is reduced to reserve area for cutting marks, then cutting marks can be printed, but productivity is reduced
Solution Approach 1:
The patent applies partial action by printing cutting marks only in the necessary margin areas rather than requiring reduction of entire image areas. This selective approach places cutting marks only where needed for cutting guidance, preserving the maximum possible image areas and maintaining high productivity while achieving accurate cutting mark positioning.
