Solution Overview
Problem
Ink jet printing on cloth faces challenges in preventing bleeding and maintaining texture, as existing methods either compromise image quality or texture due to the use of pretreatment liquids, and these issues vary with different types of cloth.
Innovation Solution
An image processing apparatus that acquires base material information and generates a pretreatment liquid image to control the application of a functional material, preventing ink wetting and spreading, thereby improving texture and image quality by optimizing the pretreatment liquid application pattern based on the cloth type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pretreatment liquid is applied to prevent bleeding, then image quality is improved, but texture of cloth deteriorates
Solution Approach 1:
The patent applies pretreatment liquid selectively only to specific regions where bleeding is likely to occur (such as along stitch lines or high-risk areas) rather than uniformly across the entire cloth. This localized application prevents bleeding in critical areas while preserving the natural texture and feel of the cloth in non-treated areas, thus resolving the contradiction between image quality improvement and texture maintenance.
Solution Approach 2:
The patent uses a minimal amount of pretreatment liquid concentrated in specific high-risk areas rather than applying a full layer across the entire surface. This partial action provides sufficient bleeding prevention where needed while minimizing the overall impact on cloth texture, achieving effective bleeding control without excessive liquid application that would deteriorate texture.
2Object-affected harmful factors
If importance is attached to texture, then texture is maintained, but bleeding prevention is insufficient and image quality deteriorates
Solution Approach 1:
The system identifies and targets specific local areas prone to bleeding (such as along stitch lines or pattern edges) for pretreatment liquid application. By concentrating the treatment only where bleeding risk exists, the cloth texture is preserved in the majority of areas while still achieving adequate bleeding prevention in the localized high-risk zones, thus maintaining both texture and image quality.
3Reliability
If pretreatment liquid is applied uniformly, then bleeding is prevented, but texture deteriorates and image quality does not improve sufficiently for various cloth types
Solution Approach 1:
The patent transitions from uniform pretreatment liquid application to localized application based on analyzing the specific cloth type, pattern characteristics, and identified high-risk bleeding areas. This targeted approach maintains reliable bleeding prevention in critical zones while avoiding unnecessary liquid application in areas where bleeding is not a concern, thereby preserving cloth texture and adapting to various cloth types effectively.
Solution Approach 2:
The system dynamically adjusts the pretreatment liquid application pattern based on the specific cloth type and image characteristics. Rather than using a fixed uniform application method, the system adapts the treatment locations and amounts according to the particular requirements of each cloth type and pattern, optimizing both bleeding prevention and texture preservation for diverse materials.

AI summary
Provided are an image processing apparatus, an image processing method, a program, and an ink jet printing system that can perform image formation capable of improving texture and preventing bleeding in a case in which printing is performed on cloth. An image processing apparatus 12 acquires base material information 42 including at least information indicating the quality of fiber in cloth which is a medium to be printed and image data 40 of a pattern to be printed on the cloth and generates a pretreatment liquid image 44 that indicates a pretreatment liquid application pattern defining a pretreatment liquid application position where a pretreatment liquid including a functional material for preventing wetting and spreading of ink in the cloth is applied and a pretreatment liquid non-application position where the application of the pretreatment liquid is limited, on the basis of the base material information 42 and the image data 40.
