Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing Web printing systems, users cannot visually confirm the bleed effect before printing, leading to potential errors in cutting positions that result in unintended blank spaces on printed materials.

Innovation Solution

A system that allows users to edit printing content with a trim line and a bleed line displayed, enabling preview of the content with expanded objects to ensure proper bleed processing and avoid cutting errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If bleed processing is performed by extending printing content to reach the bleed line outside the trim line, then unintended blank spaces are prevented even with cutting position errors, but users cannot visually confirm the bleed effect before printing leading to potential errors

Engineering Contradiction:

Improvecutting position accuracyVSAvoidvisual confirmation of bleed effect

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The system creates a visual copy or representation of the bleed effect by extending the preview region beyond the trim line to display the bleed line. This allows users to see what the bleed processing will look like without actually printing beyond the trim line, providing visual confirmation while maintaining printing precision.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system adds a visual dimension to the bleed processing by displaying the bleed line in the preview region. This creates an additional visual layer that shows the extent of bleed processing without physically extending the printed content beyond the trim line, resolving the contradiction between visual confirmation and printing accuracy.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Loss of information

If the preview region is extended to show the bleed line outside the trim line, then users can visually confirm bleed processing, but the display region becomes more complex

Engineering Contradiction:

Improvevisual confirmation of bleed effectVSAvoiddisplay region structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The display region is segmented into distinct functional areas: the trim line defining the primary content boundary, and the extended preview region showing the bleed line. This segmentation allows the complex display to be organized into manageable, clearly-defined sections that serve different purposes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extended preview region acts as an intermediary between the trim line and the actual bleed area. It provides a visual transition zone that shows users how content extends to the bleed line without directly displaying the full complexity of the bleed processing, simplifying the overall display structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A computer functions as an editing unit that can edit a printing content including one or more objects in an editing region displaying a trim line corresponding to a cutting position of a printing medium; and a display control unit that displays a region related to the printing content on a display unit. In a case where setting of cutting the printing medium on which the printing content is printed at a position of the trim line is set, the display control unit displays a bleed line, which is different from the trim line and corresponds to a position to which printing processing is performed, the position being outside the cutting position, and a preview region displaying the printing content.
