Solution Overview
Problem
Existing printing technologies face inefficiencies when adding marks to documents, leading to increased printing time, especially when combining multiple images, due to inadequate consideration of mark placement.
Innovation Solution
A control device for a printer that alternates between partial printing and sheet conveying, determining optimal head positions and relative positions of images to minimize the number of partial printings required, thereby optimizing the printing process for combined images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple images are printed by adding marks without optimizing position, then the mark can be added to the image, but the printing time becomes excessively long
Solution Approach 1:
The control device determines optimal head positions and relative positions of multiple images before printing begins. By pre-calculating the arrangement that minimizes the number of partial printings, the system prepares the printing plan in advance, avoiding time-consuming adjustments during the actual printing process.
Solution Approach 2:
The system dynamically adjusts the relative positions of multiple images based on the determined head positions in the conveying direction. This dynamic optimization ensures that images are arranged to minimize the number of partial printings required, adapting the layout to the printer's operational constraints.
2Adaptability or versatility
If the number of partial printings is increased to print multiple images, then more images can be printed, but the printing time increases excessively
Solution Approach 1:
The control device dynamically determines the optimal relative positions of multiple images based on the head positions in the conveying direction. This dynamic optimization minimizes the number of partial printings required, allowing the system to maintain high printing efficiency while accommodating multiple images on a single sheet.
Solution Approach 2:
The system changes the arrangement parameters of multiple images by adjusting their relative positions in the conveying direction. By optimizing these parameters, the system reduces the total number of partial printings needed, thereby improving overall printing productivity while maintaining the capability to print multiple images.
3Ease of manufacture
If mark position is not optimized, then the marking process is simple, but the printing time becomes excessively long
Solution Approach 1:
The control device performs preliminary determination of optimal head positions and image relative positions before the printing process begins. This pre-planning stage automates the complex positioning calculations, keeping the actual printing process simple while minimizing printing time through optimized arrangement.

AI summary
A control device for controlling a printer includes a conveyer and a print head. The control device performs: acquiring first image data representing a first image and second image data representing a second image; determining, based on the first image, a plurality of head positions of the print head relative to the first image; and determining a relative position of the second image relative to the first image such that, when the number of partial printings for printing the first image and the second image is increased from the number of partial printings for printing the first image, the relative position can minimize the increment.
