Silver Plate Generation for Glossy Monochrome Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies require the creation of a silver plate in print data and adjustment of black plate gradation for achieving desired glossy monochrome printing, which is cumbersome and lacks efficiency.
Innovation Solution
An image processing apparatus that converts input data without a silver plate into grayscale, generates silver plate data based on black plate gradation values, and combines it with black plate data to produce output data, ensuring linear brightness decrease for glossy output without empirical adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual creation of silver plate and adjustment of black plate gradation is performed, then desired glossy monochrome printing can be achieved, but the process becomes cumbersome and inefficient
Solution Approach 1:
The image processing device performs preliminary conversion of input data to grayscale and automatically generates black plate gradation values before printing. This preliminary processing eliminates the need for manual silver plate creation and black plate adjustment during the printing process, thereby maintaining high-quality glossy monochrome output while significantly improving processing efficiency
Solution Approach 2:
The system enables self-service by automatically generating special color plate data based on the converted grayscale black plate data. The image processing device autonomously determines the appropriate gradation values for special color plates without requiring manual intervention, thus resolving the contradiction between maintaining manufacturing precision and improving productivity
2Manufacturing precision
If empirical adjustments of black plate gradation are made, then optimal glossiness can be achieved, but the process requires manual tuning and time
Solution Approach 1:
The patent replaces the manual mechanical adjustment process with an automated image processing system. The circuitry automatically converts input data to grayscale and generates appropriate black plate and special color plate gradation values based on predetermined algorithms, eliminating the need for empirical manual tuning while maintaining optimal glossiness quality and significantly reducing adjustment time
3Manufacturing precision
If silver plate data is manually created, then desired special color output can be achieved, but the process lacks efficiency and automation
Solution Approach 1:
The image processing device performs self-service by automatically generating special color plate data from the converted grayscale black plate data. The system autonomously determines the gradation values for special color plates without requiring manual creation, thereby achieving both high manufacturing precision for special color output and a high extent of automation
Solution Approach 2:
The image processing device performs multiple functions within a single automated workflow: converting input data to grayscale, generating black plate data, and creating special color plate data. This multi-functionality eliminates the need for separate manual processes while maintaining quality standards, thus resolving the contradiction between manufacturing precision and automation level

AI summary
An image processing apparatus includes circuitry configured to convert input data of a plate without a special color plate into grayscale to obtain a first gradation value of a black plate, the special color plate being a plate excluding the black plate, a magenta plate, a cyan plate, and a yellow plate; generate special color plate data having a second gradation value of the special color plate based on the first gradation value of the black plate; and output output data, generated based on the special color plate data, to an image former to form a print image on a medium.
