Double-Sided Printing Image Extension for Registration Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems face issues with registration faults during double-sided printing, leading to white lines on edges and resource wastage due to misalignment and process interruptions.
Innovation Solution
Automatically creating an extended back side image with additional pixels surrounding the original image and filling them with matching colors to ensure accurate alignment and printing, eliminating visible artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If double-sided printing is performed without extending the back side image, then printing speed is maintained, but registration faults occur causing white lines on edges
Solution Approach 1:
The patent applies preliminary action by automatically extending the back side image with additional pixels before printing occurs. This pre-processing step ensures that when the recording medium is fed through the printer, the extended image areas provide proper alignment margins, preventing registration faults and white lines at the edges during the actual printing process.
2Manufacturing precision
If manual alignment adjustment is performed, then alignment precision can be improved, but processing time increases
Solution Approach 1:
The patent implements self-service by having the printing system automatically extend the back side image with additional pixels without requiring manual intervention. The system self-adjusts the alignment by generating the extended image data, eliminating the need for operator involvement in alignment adjustment and thereby reducing processing time while maintaining precision.
3Manufacturing precision
If the back side image is extended with additional pixels, then alignment precision is improved, but image data complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the image data parameters - specifically adding additional pixels around the back side image boundaries. This transforms the image from its original compact form to an extended form with proper alignment margins, achieving better alignment precision through controlled parameter modification rather than complex processing algorithms.

AI summary
A method for double-sided printing of a plurality of digital images on a recording medium by means of a printing system. Each image of the plurality of digital images consisting of a plurality of pixels. The method comprises the steps of receiving a front side image to be printed at a first location on a first side of the recording medium, receiving a back side image to be printed at a second location on a second side of the recording medium corresponding to the location on the first side of the recording medium, providing the front side image with cut marks for a cutting process applied to the front side image, wherein the cutting process is planned after printing on both sides of the recording medium, printing the front side image and the cut marks at the first location on the first side of the recording medium, automatically creating an extended back side image which comprises the back side image and additional pixels surrounding the back side image, automatically establishing a fill out of the additional pixels by coloured pixels, and printing the extended back side image at the second side of the recording medium such that the back side image is printed at the second location on the second side of the recording medium.
