Printing Control Device Code Information Readability

Solution Overview

Problem

There is no information on printed matter indicating the location of the web page where an image was published, making it difficult for users to identify the original web page after printing.

Innovation Solution

A printing control device and method that includes a specification receiving unit to select images, an image acquisition unit to acquire images, an access information acquisition unit to get access information, a code information creation unit to create code information, and a printing execution unit to print the image and code information together, allowing users to easily identify the web page by reading the code.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If code information is printed on paper that bleeds easily, then the printing process is simple, but the readability of the code information deteriorates

Engineering Contradiction:

Improveprinting process simplicityVSAvoidcode information readability

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent applies local quality by adjusting the ink density specifically for the code information area based on paper type. For papers prone to bleeding, the ink density is reduced only in the code information region, while other areas may maintain normal density. This localized adjustment prevents code smearing while preserving overall print quality.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the ink density parameter dynamically based on the detected paper type. When bleeding-prone paper is detected, the system automatically reduces the ink density for code information printing. This parameter adjustment resolves the contradiction by adapting the printing process to the specific paper characteristics.

Inventive Principle:

Principle #35Parameter changes

2Illumination intensity

If code information is printed with high ink density, then the code information is more visible, but ink bleeding occurs on certain paper types

Engineering Contradiction:

Improvecode information visibilityVSAvoidink bleeding

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by adjusting the ink density specifically for the code information area based on paper type. For papers prone to bleeding, the ink density is reduced only in the code information region, while other areas may maintain normal density. This localized adjustment prevents code smearing while preserving overall print quality.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the ink density parameter dynamically based on the detected paper type. When bleeding-prone paper is detected, the system automatically reduces the ink density for code information printing. This parameter adjustment resolves the contradiction by adapting the printing process to the specific paper characteristics.

Inventive Principle:

Principle #35Parameter changes

3Area of stationary object

If the code information size is reduced, then more space is available on the printed material, but the code becomes harder to read

Engineering Contradiction:

Improveavailable space on printed materialVSAvoidcode information readability

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The patent changes the code information size parameter dynamically based on the detected paper type. For papers prone to bleeding, the system reduces the code size to accommodate the reduced ink density and prevent smearing. This automatic parameter adjustment resolves the contradiction by adapting the code dimensions to the paper characteristics.

Inventive Principle:

AI summary

A printing control device, a program, and a printing method is provided for creating printed matter for which a user can easily identify a web page on which an image included in the printed matter is published. A printing control device accessible to a server for managing a web site through a network includes a specification receiving unit receiving specification of an image published on the web site, an image acquisition unit acquiring the specified image through the server, an access information acquisition unit acquiring access information for accessing a web page on which the image is published on the web site, a code information creation unit creating code information expressing the access information using text or an image, and a printing execution unit making a printer print a synthetic image in which the acquired image and the created code information are included.
