Printing Apparatus Dynamic Transport Control for Speed and Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing technologies face challenges in maintaining printing quality and increasing speed due to the risks associated with overlapping transport of printing media, where the timing of image data creation and printing can lead to reduced quality and inefficient speed gains.
Innovation Solution
A printing apparatus and method that dynamically switch between two printing processes for the lower end portion of an image based on whether image data creation precedes printing, using either overlapping transport or a normal process, to stabilize the printing medium and optimize speed and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If overlapping transport is used to increase printing speed, then printing speed is improved, but printing quality deteriorates due to the risk of the printing medium approaching or contacting the printing mechanism
Solution Approach 1:
The patent applies dynamics by making the transport mode changeable based on real-time conditions. The control portion dynamically switches between overlapping transport and non-overlapping transport depending on whether image data creation is precedent, allowing the system to adapt its transport characteristics to maintain quality while maximizing speed when conditions permit
Solution Approach 2:
The patent changes the transport parameter (overlapping distance/timing) based on the temporal relationship between image data creation and printing. When image data creation is precedent, overlapping transport parameters are applied to increase speed; otherwise, non-overlapping parameters are used to ensure quality, thus optimizing both speed and quality through parameter adjustment
2Productivity
If overlapping transport is executed without proper timing coordination, then printing speed may increase, but the temporal relationship between image data creation and printing breaks down导致 printing quality reduction
Solution Approach 1:
The control portion continuously monitors the temporal relationship between image data creation and printing processes. Based on this feedback (whether image data creation is precedent), the system automatically adjusts the transport mode, ensuring that overlapping transport is only executed when the timing relationship supports quality printing, thus maintaining reliability while enabling speed improvement
3Manufacturing precision
If the lower end portion of the printing medium is stabilized during printing, then printing quality is improved, but the ability to execute overlapping transport is reduced
Solution Approach 1:
The patent makes the transport stability dynamic rather than fixed. The lower end portion is stabilized only when necessary (when image data creation is not precedent), while allowing overlapping transport when conditions permit (when image data creation is precedent). This dynamic approach resolves the contradiction by adapting stability requirements to actual printing conditions
Data Source
AI summary
A printing apparatus includes a data processing portion that creates image data that corresponds to printing of a predetermined unit, a transport portion that transports a printing medium, and a printing portion that executes the printing of the predetermined unit on the printing medium on the basis of the image data, in which the data processing portion determines whether or not the creation of image data precedes the printing, causes the printing portion to execute a first printing process for printing of a lower end portion of an image of a printing target in a case in which the creation of image data is precedent, and causes the printing portion to execute a second printing process for printing of the lower end portion in a case in which the creation of image data is not precedent.
