Dynamic Color Patch Arrangement for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color administration in image forming apparatuses requires numerous color patches, which can lead to space constraints and incomplete color management due to limited space for patch arrangement, resulting in inadequate color reproduction.
Innovation Solution
A control apparatus that extracts missing color information from a page's image data, creates and arranges only the necessary color patches for each page, and sends the updated image data for printing, allowing for efficient color administration without the need for extensive patch arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous color patches are arranged at the end portion of a printed sheet for feedback control, then color administration accuracy is improved, but the available space for printing content is reduced and some color patches may be dropped
Solution Approach 1:
The patent extracts only the necessary color patches required for specific color administration purposes from the complete set of potential color patches. The control apparatus analyzes the print job data to determine which color patches are actually needed for feedback control, and arranges only those selected patches at the end portion of the printed sheet, rather than arranging all possible color patches.
Solution Approach 2:
The patent segments the color administration process by dividing color patches into different categories based on their functional requirements. Different types of color patches (e.g., for density measurement, colorimetry, specific color spaces) are selectively arranged according to the specific color administration needs of the print job, rather than using a fixed comprehensive set of patches.
2Area of stationary object
If the number of color patches is reduced to secure printing space, then available printing space is improved, but color administration completeness deteriorates
Solution Approach 1:
The patent implements a dynamic color patch arrangement system where the control apparatus automatically adjusts the number and types of color patches based on the specific characteristics of each print job. The system analyzes the job data to determine the appropriate set of color patches needed, dynamically generating a customized patch arrangement rather than using a static fixed set of patches.
Solution Approach 2:
The patent changes the parameters of color patch arrangement by varying the number, types, and positions of color patches according to the specific color administration requirements of different print jobs. The control apparatus modifies the patch configuration parameters dynamically based on job analysis, ensuring optimal color administration for each specific case.
Data Source
AI summary
Provided are a control apparatus for controlling an image forming apparatus including an inline sensor, and a non-transitory computer-readable storage medium storing a control program. The control apparatus includes: a data analyzing section configured to extract color information contained in an image of a certain page of a job and determine whether there is missing color information necessary for color administration of the job in the extracted color information; a color patch creating section configured to create a color patch or color patches corresponding to the missing color information and arrange the color patch or color patches in the certain page; and a control section configured to send image data of the certain page in which the color patch or color patches are arranged to the image forming apparatus so as to make the image forming apparatus perform print processing and measuring color information.
