Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing methods require spot checks and trial and error for color adjustment, leading to inefficiencies in ensuring print quality before mass production, as they involve separate machines for proofing and production, necessitating additional steps and resources.
Innovation Solution
A method involving a first printing unit simulating the settings of a second printing unit, with data transmission and colorimetric results used to adjust and verify printing settings, allowing for efficient proofing and production without the need for separate machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated machine is used for creating proofs and a separate mass-production machine is used for printing, then print quality can be checked before production, but the process requires multiple machines and additional steps
Solution Approach 1:
The mass-production printing machine is made capable of performing both mass-production printing and proof creation functions. The control unit can switch between different operating modes, allowing the same hardware to serve multiple purposes - either producing bulk prints or generating quality proofs, thereby eliminating the need for a separate dedicated proofing machine
Solution Approach 2:
The patent combines the proof creation function and mass-production printing function into a single integrated system. By merging these previously separate operations into one machine with a unified control unit, the system reduces device complexity while maintaining the ability to perform both quality verification and production tasks
2Reliability
If spot check and trial and error for color adjustment are performed, then print quality can be verified, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system performs preliminary color adjustment using the colorimetric measurement results obtained from the proof printed by the mass-production machine itself. By measuring the actual printed proof and calculating required color adjustments in advance, the system prepares corrected printing data before full production, eliminating the need for repeated trial and error printing
Solution Approach 2:
The system implements a feedback loop where the colorimetric measurement results from the printed proof are fed back to calculate color adjustment values. This feedback mechanism allows the control unit to automatically determine the necessary color corrections and generate adjusted printing data, replacing manual spot checks and iterative adjustments with an automated measurement-correction system
3Ease of operation
If separate machines are used for proofing and production, then color adjustment can be performed, but additional resources and steps are required
Solution Approach 1:
By merging the proof creation and production functions into a single machine, the patent eliminates the need for data transmission between separate machines. The control unit directly generates corrected printing data based on colorimetric measurements and sends it to the same machine's printing unit, removing coordination overhead and communication delays
Solution Approach 2:
The control unit acts as an intermediary that processes colorimetric measurement results and automatically generates color-adjusted printing data. This intermediary function replaces manual color adjustment operations and eliminates the need for human operators to physically handle proofs and make adjustments, streamlining the workflow within a single machine
