Solution Overview

Problem

Existing image-forming devices require suspending printing tasks during color calibration, leading to prolonged completion times and poor user experience due to inefficient use of the device.

Innovation Solution

A method that allows simultaneous execution of image-forming tasks and color calibration tasks by determining whether the size of the imaging medium is within a preset range, enabling the tasks to be performed without overlapping imaging areas.

1Measurement precision

If color calibration is performed, then color accuracy is improved, but printing task completion time increases

Engineering Contradiction:

Improvecolor accuracyVSAvoidprinting task completion time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments the imaging medium into different regions: a first region for normal printing tasks and a second region for color calibration. By dividing the imaging medium and assigning different functions to different regions, the system can simultaneously perform printing and color calibration without interference, thus improving color accuracy while maintaining printing efficiency.

Inventive Principle:

Principle #1Segmentation

2Productivity

If color calibration is performed simultaneously with printing task, then device efficiency is improved, but image quality may deteriorate due to overlapping imaging areas

Engineering Contradiction:

Improvedevice efficiencyVSAvoidimage quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent divides the imaging medium into distinct first and second regions, where the first region is used for printing tasks and the second region is used for color calibration. This spatial segmentation prevents overlapping of imaging areas, ensuring that both printing quality and color calibration accuracy are maintained while improving device efficiency through simultaneous operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the imaging medium are assigned different functional qualities: the first region is optimized for printing with appropriate imaging parameters, while the second region is optimized for color calibration. This local differentiation of quality characteristics allows simultaneous operations without mutual interference, maintaining both image quality and calibration accuracy.

Inventive Principle:

Principle #3Local quality

AI summary

A color calibration method applied to an image-forming device includes: determining whether there is a first task which is an image-forming task being executed or an image-forming task to be executed; when the first task exists, acquiring a size of a first imaging medium corresponding to the first task; determining whether the size of the first imaging medium is within a preset range; and when the size of the first imaging medium is within the preset range, executing the first task and a color calibration task at the same time.
