Solution Overview

Problem

Traditional CMYK laser or LED printers are unable to print in white, metallic, or light toner as they lack the necessary toner and drum cartridges and RIP software for cartridge re-mapping, limiting their ability to produce high-quality prints on dark or clear media and requiring expensive specialized printing methods for metallic tones.

Innovation Solution

Converting a standard CMYK toner printer by replacing the black toner cartridge with a white, metallic, or light toner cartridge and using RIP software for cartridge re-mapping, allowing the printer to print white, metallic, or light toner as a background or foreground color, and enabling layered printing with CMYW or CMYW configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a standard CMYK printer is used, then it can print traditional colors, but it cannot print white, metallic, or light toner

Engineering Contradiction:
Improvetoner color capabilityVSAvoidprinter configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent changes the toner parameter from traditional CMYK to include white, metallic, or light toner by replacing the black toner cartridge. This allows the printer to achieve new color capabilities without fundamentally changing the printer's core structure, resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent makes the existing printer multi-functional by enabling it to print with different toner types (white, metallic, light) through cartridge replacement and software re-mapping. The printer maintains its original CMYK capability while gaining additional toner options, achieving universality without requiring multiple dedicated printers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If white toner is printed as the last cartridge in CMYKW printers, then white can be printed, but it cannot serve as a background color layer

Engineering Contradiction:
Improvewhite toner positioningVSAvoidlayer printing control
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary action by printing the white toner layer first as a background, before applying other color layers. The RIP software is configured to remap the white toner cartridge to the black cartridge position, enabling the printer to deposit white toner first and then subsequent color layers on top, achieving precise layer control for background printing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The RIP software acts as an intermediary between the user's print job and the printer hardware. It remaps the white toner cartridge to the black cartridge position and controls the printing sequence, enabling precise layer management without requiring physical modification to the printer's printing mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If traditional CMYK colors are used to approximate metallic tones, then printing is possible, but the quality and authenticity of metallic appearance is poor

Engineering Contradiction:
Improvemetallic tone qualityVSAvoidtoner type variety
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent changes the toner material parameter from traditional CMYK pigments to metallic or fluorescent toner particles. This material parameter change enables authentic metallic appearance and lightfast properties that cannot be achieved through color blending, directly improving manufacturing precision for metallic tones.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite toner materials with special properties (metallic particles, fluorescent compounds) that combine optical effects with printing capability. These composite materials provide authentic metallic appearance and enhanced lightfastness, resolving the limitation of approximating metallic tones with traditional CMYK colors.

Inventive Principle:
Principle #40Composite materials

4Manufacturing precision

If primary CMYK colors are used for light colors, then printing is possible, but lightfastness and image quality are compromised

Engineering Contradiction:
Improvelight color quality and lightfastnessVSAvoidtoner cartridge configuration
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent changes the toner material parameter to lightfast pigments and fluorescent compounds that maintain color stability and brightness. These specialized toner materials provide superior lightfastness and image quality for light colors compared to traditional CMYK, resolving the contradiction between quality and complexity through material substitution.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of converting a CMYK printer to print with a non-standard toner, comprising the steps: providing a CMYK toner printer; wherein the CMYK toner printer may have four toner printing cartridges, wherein three of the four toner printing cartridges may be color printing cartridges comprising a cyan toner printing cartridge, a magenta toner printing cartridge, and a yellow toner printing cartridge; removing one or more of the color toner printing cartridges from the toner printer, such that there may be one or more empty toner printing cartridge positions; providing one or more non-standard toner printing cartridges; and installing the one or more non-standard toner printing cartridges into the one or more empty toner printing cartridges.
