Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing printing technologies do not adequately consider the quality of printing when determining the printing method, particularly in terms of the area occupied by visual content such as images, shading, and screen tint in the print target screen.

Innovation Solution

A method and device that determine the printing method by calculating the ratio of the area of content components (such as images, gradations, and screen tints) to the page region, and selecting the appropriate printing method based on these ratios to ensure optimal printing quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If printing method is determined based on ink consumption amount prediction, then cost efficiency is improved, but printing quality is deteriorated

Engineering Contradiction:

Improveink consumptionVSAvoidprinting quality

Core Design Contradiction:

Loss of substanceVSManufacturing precision

Solution Approach 1:

The patent segments the page data into multiple content components (image components, gradation components, screen tint components, and form components) and calculates the area ratio of each type separately. This segmentation allows for differentiated printing method determination based on the specific characteristics and area ratios of different content types, rather than using a single ink consumption metric for the entire page.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by determining printing methods based on the area ratios of different content component types in specific regions of the page. Different printing methods can be selected for different content components based on their local area ratios and characteristics, ensuring optimal printing quality for each region while considering overall ink consumption.

Inventive Principle:

Principle #3Local quality

2Productivity

If printing condition is selected based on RIP processing simulation, then productivity is improved, but printing quality consideration is deteriorated

Engineering Contradiction:

Improveprocessing speedVSAvoidprinting quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary analysis by calculating the area ratios of different content components before RIP processing. This preliminary action provides quality-based printing method determination that can guide subsequent processing, ensuring quality considerations are integrated into the workflow without significantly delaying productivity.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If ink consumption prediction is used for printing cost determination, then ease of operation is improved, but printing quality optimization is deteriorated

Engineering Contradiction:

Improvesimplicity of determinationVSAvoidprinting quality

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent changes the determination parameter from a single ink consumption amount to multiple area ratio parameters (image component area ratio, gradation component area ratio, screen tint component area ratio). This parameter change maintains ease of operation through automated calculation while enabling quality optimization by considering the specific characteristics of different content types.

Inventive Principle:

AI summary

A screen is regulated by page data, a range of a page in the screen is regulated by a page region, and the page data includes a content component arranged in the page region and regulating the content. A printing method determination method obtains a ratio of an area of the content component to the page region, and determines the printing method based on the ratio.
