Solution Overview

Problem

Current large format printing processes are cumbersome and time-consuming due to the need for frequent manual intervention to change media types, leading to reduced productivity and increased maintenance costs, especially when handling documents with multiple pages requiring different print settings.

Innovation Solution

A print control system that generates and manages multiple print jobs based on varying media types and page settings, allowing for efficient processing of documents with different media requirements without manual intervention, by utilizing printers with multiple media sources and integrating print job generation, media selection, and accessory management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual intervention is used to change media types for each print job, then printing flexibility and media type matching are improved, but productivity is reduced and maintenance costs increase

Engineering Contradiction:
Improvemedia type matchingVSAvoidprinting throughput
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments the print job processing by creating separate print jobs for different media types. Each print job is associated with a specific media source, allowing the printer to automatically select and switch between multiple media sources without manual intervention. This segmentation enables both media type matching and continuous operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-configuring multiple media sources and pre-segmenting the document into multiple print jobs with different media requirements. This preparation allows the printer to automatically switch between media types without stopping for manual intervention, thereby maintaining both adaptability and productivity.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual intervention is required to change media rolls, then media type precision is improved, but time consumption and operational complexity increase

Engineering Contradiction:
Improvemedia type precisionVSAvoidmedia change time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system implements dynamic media source selection where the printer automatically switches between multiple pre-loaded media sources based on the requirements of each print job. This dynamic switching eliminates the need for manual media changes while maintaining precise media type matching, thereby reducing media change time to zero.

Inventive Principle:
Principle #15Dynamics

3Loss of substance

If multiple print jobs are created for different media types, then media wastage is reduced, but system complexity increases

Engineering Contradiction:
Improvemedia wastageVSAvoidprint job management
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The printer is configured with multiple media sources and the capability to handle multiple print jobs with different media requirements in a universal system. This multi-functionality allows the single printer to efficiently manage diverse media types without requiring separate printing systems, thereby reducing media wastage while keeping the system manageable.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems and methods for printing with multiple print settings are described herein. In one implementation, the method of printing with multiple print settings comprises receiving a job file indicative of a print assignment comprising a plurality of pages, wherein at least one of the plurality of pages has a different print setting. The method further comprises analyzing the job file to determine page settings for each of the plurality of page assignments. A print job is generated for printing each of the plurality of pages in accordance with the print setting and page settings associated with each of the plurality of pages.
