Solution Overview

Problem

Existing print recording systems require complex manual settings by operators to achieve high-quality printing, which varies with production line speed, print head distance, and print posture, leading to inconsistent print quality due to operator skill variability.

Innovation Solution

A system and method that facilitates easy setting of print settings using a computer system with a server and terminal device, allowing search and application of print setting information based on predefined criteria, enabling automated and accurate setting adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual setting operations are performed by operators based on previous experience, then print quality can be adjusted, but the setting operation becomes extremely complicated and time-consuming

Engineering Contradiction:
Improveprint qualityVSAvoidsetting operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system pre-registers multiple sets of setting information corresponding to different print conditions (transport speed, distance, posture) in a database before actual printing operations. When printing is needed, the system automatically retrieves the pre-prepared setting information matching the current conditions, eliminating the need for operators to manually adjust each parameter based on experience.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual setting operations are performed by operators, then print settings can be adjusted, but setting content varies greatly according to operator deftness making it difficult to stably maintain excellent print quality

Engineering Contradiction:
Improveprint qualityVSAvoidprint quality consistency
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The system enables self-service printing by automatically selecting and applying the appropriate setting information from the database based on detected print conditions (transport speed, distance, posture). This automation removes human variability from the setting process, ensuring consistent and reliable print quality regardless of operator skill level.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If comprehensive setting information is stored for all print conditions, then print quality can be optimized, but the system complexity increases

Engineering Contradiction:
Improveprint qualityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system segments setting information into distinct, standardized parameters (transport speed, distance, posture, and corresponding print settings) and stores them as separate records in a database. Each record corresponds to a specific combination of print conditions, allowing the system to manage complexity through structured data organization rather than complex hardware or software architecture.

Inventive Principle:
Principle #1Segmentation

AI summary

Provided are a print recording system and a method for controlling a print recording system that enable print setting information affecting print quality to be easily set. The present invention is configured by a print recording system, including: at least one print recording device; and a computer system that includes a database storing a plurality of print setting information items and is capable of sending and receiving data with respect to the print recording device. The computer system searches the print setting information corresponding to a search condition that is input from the database in accordance with the search condition, repeats the search in accordance with a new search condition when the print setting information does not match the search condition, and sends the print setting information obtained by the search or the repeated search to the print recording device to set the print recording device.
