Continuous Form Paper Waste Allocation in Printing Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In printing companies, the generation of waste paper on continuous form paper is not accurately accounted for on a job-by-job basis, making cost management inefficient due to the structural generation of waste before and after printing.
Innovation Solution
A printing management apparatus that calculates and allocates the amount of waste paper generated during printing on continuous form paper to each job by determining the transport start and end points, allowing for precise allocation and output of waste paper amounts for each job.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If printing is performed on continuous form paper with waiting for transport speed stabilization, then printing image quality is guaranteed, but waste paper is generated before and after printing
Solution Approach 1:
The system performs preliminary actions by pre-calculating waste paper amounts for different printing conditions and storing them in a database. When a printing job is executed, the corresponding waste paper amount is automatically retrieved and allocated to the job, eliminating the need for real-time calculation and enabling accurate job-by-job accounting despite the structural waste generation inherent in continuous form paper printing
2Loss of substance
If multiple jobs are continuously processed to reduce waste paper, then waste paper amount is reduced, but accurate job-by-job cost management becomes difficult
Solution Approach 1:
The system segments the total waste paper amount into job-specific portions by allocating waste paper amounts to individual jobs based on their printing conditions. The waste paper amount database stores segmented information for different print settings, post-processing settings, and paper types, enabling both continuous processing efficiency and accurate job-by-job cost management simultaneously
3Ease of manufacture
If waste paper amount is calculated manually by excluding paper length used for actual printing, then cost management is performed, but accurate measurement and allocation to each job is inefficient
Solution Approach 1:
The system replaces the manual mechanical calculation method with an automated information processing system. A waste paper amount database stores pre-calculated waste paper amounts for various printing conditions, and a processing unit automatically retrieves and allocates the appropriate waste paper amount to each job based on printing conditions, eliminating manual measurement and calculation while improving accuracy and efficiency

AI summary
A printing management apparatus includes a memory; and a processor that is connected to the memory, in which, in a case where a printing apparatus, which performs printing on continuous form paper, processes plural jobs with respect to the continuous form paper in one-time printing, the processor calculates a length, which is acquired by excluding a part used to print the plural jobs from a length determined by a transport start spot, at which transport of the continuous form paper starts and a transport end spot at which the transport of the continuous form paper ends, as an amount of waste paper indicative of a part which becomes a loss of the continuous form paper, and outputs an amount of waste paper for each job of plurality of jobs, which is acquired by allocating the calculated amount of waste paper to the plural jobs.
