Variable Base Ink Application for Nail Printing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail printing devices apply a fixed amount of white base ink, which can be wasteful and inefficient, especially for dark-colored designs where the base ink's influence is minimal, and do not allow for precise adjustment of base ink density based on the design.
Innovation Solution
A printing system that includes a processor to set and control the application amount of base ink according to the selected nail design, using a base density table to determine the appropriate amount for optimal color tint and translucency, allowing for adjustable base ink application based on design requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed amount of white base ink is applied to all nail designs, then the base provides consistent coverage, but ink is wasted on dark-colored designs where the base ink's influence is minimal
Solution Approach 1:
The patent changes the parameter of base ink application amount from a fixed value to a variable value that depends on the design characteristics. The control unit adjusts the base ink application amount based on the luminance or color information of the design image, applying more base ink to light-colored designs and less to dark-colored designs, thereby eliminating waste while maintaining adequate coverage where needed
Solution Approach 2:
The patent introduces dynamic adjustment of the base ink application amount based on real-time analysis of design characteristics. The system dynamically determines the appropriate base ink amount for each design before printing, making the printing process adaptive rather than static, which resolves the contradiction between consistent coverage and ink waste
2Ease of manufacture
If a fixed amount of white base ink is applied to all nail designs, then the printing process is simple, but precise adjustment of base ink density based on design is not possible
Solution Approach 1:
The patent performs preliminary analysis of the design image before the actual printing process. The control unit extracts color or luminance information from the design image and determines the appropriate base ink application amount in advance, allowing precise control to be built into the process without complicating the user interface or operation
3Reliability
If the base ink application amount is increased to ensure coverage for all designs, then coverage is adequate, but the printing time increases due to applying more ink than necessary
Solution Approach 1:
The patent changes the base ink application parameter from a conservative fixed high value to an optimized variable value. By analyzing design characteristics and adjusting the base ink amount accordingly, the system maintains adequate coverage for light-colored designs while reducing ink application for dark-colored designs, thereby shortening printing time without sacrificing coverage quality

AI summary
Disclosed is a printing system including at least one processor and a print head which performs printing on a printing target. The processor sets an application amount of a base ink to be applied to the printing target according to a design to be printed on the printing target by the print head, and controls the print head to apply the base ink to the printing target based on the set application amount of the base ink.
