Solution Overview

Problem

Existing image forming systems struggle with synchronizing layout changes between toner images and varnish images, leading to deviations and requiring separate and cumbersome layout adjustments for varnish images.

Innovation Solution

An image forming system that includes an input unit for data change processing, a first image processing unit for toner images, and a second image processing unit for varnish images, allowing for simultaneous data change processing of both image types based on user input, ensuring synchronized layout changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate layout adjustment processes are used for toner images and varnish images, then each image can be adjusted independently, but the operation process becomes cumbersome and time-consuming

Engineering Contradiction:

Improvelayout adjustment operationVSAvoidlayout adjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the layout adjustment operations for toner images and varnish images into a single unified process. The control unit automatically applies the same layout changes (reduction, magnification, arrangement) to both image types simultaneously, eliminating the need for separate manual adjustments and significantly reducing operation time while maintaining ease of use.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The control unit is designed with multi-functionality to handle both toner image and varnish image processing. It can automatically recognize and apply layout changes to multiple image types based on a single user input, making the system versatile and eliminating the need for separate adjustment procedures for different image types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If layout changes are applied to toner images, then the toner image layout is updated, but the varnish image layout may deviate requiring separate adjustment

Engineering Contradiction:

Improveimage layout synchronizationVSAvoidimage processing system

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The control unit implements a feedback mechanism where it monitors layout changes applied to toner images and automatically applies corresponding adjustments to varnish images. This closed-loop control ensures that both image types remain synchronized in layout, preventing deviations and maintaining manufacturing precision without requiring complex manual intervention.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary action by pre-configuring the control unit to automatically apply layout changes to both toner and varnish images simultaneously. This proactive approach ensures that layout synchronization is maintained from the outset, preventing deviations before they occur and simplifying the overall system operation despite the dual-image processing requirement.

Inventive Principle:

Principle #10Preliminary action

AI summary

An image forming system includes an image forming apparatus, a varnish applying apparatus, an input unit, a first image processing unit, and a second image processing unit. The image forming apparatus forms a toner image on a recording material on the basis of image data obtained by subjecting first image data to data change processing. The varnish applying apparatus forms a varnish image on the recording material on the basis of image data obtained by subjecting second image data to the data change processing.
