Disjoint Nozzle Set Printing for Dual Image Swath Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers struggle to efficiently print multiple digital representations on the same side of a medium, such as transparent or translucent media, to achieve desired visual effects like optical interactions or compensate for printing quality defects.
Innovation Solution
A method is developed to use a single die with disjoint nozzle sets to concurrently print different representations on the same side of a medium, utilizing a single printing fluid and communicating print data to specific nozzle sets to achieve this.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual jet streams are communicated to multiple nozzle sets, then production efficiency and material utilization are improved, but the risk of cross-contamination between different jet streams increases
Solution Approach 1:
The system divides the communication path into separate dedicated channels for each nozzle set. Each jet stream has its own isolated communication path from the cartridge to the specific nozzle set, preventing mixing or cross-contamination while allowing parallel operation of multiple nozzle sets.
Solution Approach 2:
A dedicated communication path acts as an intermediary between the cartridge and each nozzle set. This intermediary structure ensures that jet streams are transmitted through separate, isolated routes, eliminating direct contact between different jet streams while maintaining efficient material transfer.
2Device complexity
If a single communication path is used for multiple nozzle sets, then device complexity is reduced, but the ability to independently control and switch between different jet streams deteriorates
Solution Approach 1:
The communication path is segmented into multiple independent channels, each dedicated to a specific nozzle set. This segmentation provides independent control capability for each jet stream while maintaining a relatively simple overall structure compared to fully independent external pathways.
Solution Approach 2:
The cartridge is designed with multi-functionality to serve multiple nozzle sets through dedicated communication paths. Each communication path can independently handle different jet streams, allowing the system to adapt to various printing requirements while maintaining structural efficiency.
3Quantity of substance
If jet streams are shared across multiple nozzle sets, then material utilization efficiency is improved, but the precision and purity of each jet stream may deteriorate
Solution Approach 1:
The communication path is divided into separate dedicated channels for each nozzle set, ensuring that each jet stream maintains its purity and intended composition. This segmentation prevents cross-contamination while enabling efficient material distribution to multiple nozzle sets simultaneously.
Solution Approach 2:
Dedicated communication paths serve as intermediaries that preserve the integrity of each jet stream during transmission. These isolated pathways ensure that materials maintain their specified purity and composition characteristics while being efficiently distributed to multiple nozzle sets.

AI summary
A printing method is described in which a first and a second digital representation data for a first and a second digital representation to be printed on a same side of a same media is received. First print data (121) corresponding to a printing fluid for the first digital representation is determined on the basis of the first digital representation data. Second print data (132) corresponding to the printing fluid for the second digital representation is determined on the basis of the second digital representation data. The method further comprises communicating the first print data corresponding to a specific swath (145) to a first set of nozzles, and communicating the second print data corresponding to the specific swath to a second set of nozzles, whereby the first and the second set of nozzles are disjoint sets of nozzles from a same die and are fluidically connected to the printing fluid.
