Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional digital book production workflows face issues such as mismatch problems between book blocks and covers, miscount errors, and inefficiencies due to different printing equipment being used for blocks and covers, leading to difficulties in recovery and increased production time.

Innovation Solution

A cover-driven system and method where covers are examined to identify corresponding book blocks, with raster image processing and binding occurring before printing, allowing for in-line or off-line binding and utilizing digital front ends to manage the retrieval and printing of book blocks and covers based on cover information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If book blocks and covers are printed on different equipment using conventional workflows, then printing flexibility is improved, but mismatch problems and miscount errors occur between book blocks and covers

Engineering Contradiction:

Improveprinting flexibilityVSAvoidassociation accuracy between book blocks and covers

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary system comprising a cover repository, book block repository, and digital front ends that mediate between the cover printing equipment and book block printing equipment. This intermediary manages the association between covers and book blocks through electronic file tracking and coordination, ensuring reliable matching while allowing different printing equipment to be used simultaneously.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the digital front ends continuously monitor and exchange information about cover printing status, book block printing status, and binding readiness. This feedback loop enables real-time coordination between different printing equipment, preventing mismatches and miscounts by adjusting printing operations based on current system state.

Inventive Principle:

Principle #23Feedback

2Reliability

If book block printing is initiated after cover printing is completed to avoid mismatch problems, then association accuracy is improved, but production time and efficiency worsen

Engineering Contradiction:

Improveassociation accuracy between book blocks and coversVSAvoidproduction time

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by pre-processing book block files through raster image processing (RIP) and preparing them in the book block repository before cover printing is completed. The digital front end pre-organizes book block electronic files and coordinates their printing schedule in advance, so that book blocks are ready for immediate binding as soon as covers are printed, eliminating waiting time while ensuring correct association.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuity of useful action by overlapping the printing operations of covers and book blocks through coordinated scheduling. While covers are being printed, the digital front end continuously prepares book block files and initiates their printing process. This continuous coordination ensures that both printing operations proceed simultaneously without interruption, maximizing productivity while maintaining association accuracy through the intermediary system.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If the printing system shuts down to detect book block/cover mismatch in the finishing system, then association accuracy is improved, but production time and system availability worsen

Engineering Contradiction:

Improvedetection accuracy of mismatchVSAvoiddowntime for error detection and recovery

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system uses continuous feedback from digital front ends that monitor the association between covers and book blocks throughout the printing and binding process. This real-time feedback enables early detection of potential mismatches before they reach the finishing system, allowing corrective action to be taken during printing operations rather than requiring system shutdown after mismatch detection in finishing.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary verification of book block and cover associations through the digital front end coordination system before the materials reach the finishing system. By pre-validating the matching between covers and book blocks during the printing phase, the system prevents mismatches from occurring in the first place, eliminating the need for shutdown-based detection and recovery in the finishing system.

Inventive Principle:

Principle #10Preliminary action

AI summary

A cover-driven book production method and system are disclosed. The method of cover-driven book production includes providing a plurality of book covers. The book covers can be identified using, for example, a scanner. A book block can then be retrieved from a book repository based on the identified cover. After performing raster image processing (RIP) of the book block, copies of the book block can be printed. Finishing can be accomplished by binding the printed book blocks to the book covers using an in-line binder or off-line binder.
