Solution Overview
Problem
Current drying and curing processes for inks and paints are inefficient, leading to prolonged drying times, especially in adverse environmental conditions, and existing additives often compromise on press runability or increase costs without adequately reducing cure time.
Innovation Solution
A drying enhancer comprising a cobalt drier with 12% cobalt by weight, manganese drier, tung oil, water-activated drier, two-way drier, and lithographic overprint varnish, which can be used at higher concentrations to accelerate the drying of inks and paints, improving their curing rates and compatibility with various substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional drying agents are used, then drying time is reduced, but press runability deteriorates and costs increase
Solution Approach 1:
The patent changes the chemical parameters of the drying agent by specifying precise cobalt content (6-14% by weight) and incorporating multiple drying agents in specific proportions. This optimized composition achieves faster drying times while maintaining press runability, resolving the contradiction between drying speed and operational ease.
Solution Approach 2:
The invention uses a composite drying agent system containing multiple components: cobalt-based drying agent (6-14%), manganese-based drying agent (1-5%), and sulfur-based drying agent (1-5%). This composite formulation synergistically improves drying performance while maintaining compatibility with printing press operations, thereby resolving the contradiction between reduced drying time and maintained press runability.
2Loss of time
If cobalt concentration is increased to accelerate drying, then drying time is reduced, but substrate compatibility deteriorates
Solution Approach 1:
The patent optimizes the cobalt concentration parameter within a specific range (6-14% by weight) rather than using maximum concentrations. This balanced parameter selection achieves significant drying time reduction (up to 50% faster) while maintaining substrate compatibility, resolving the contradiction between drying speed and adaptability.
Solution Approach 2:
The invention combines multiple drying agents (cobalt, manganese, sulfur) in specific proportions to create a composite formulation that provides both fast drying action and broad substrate compatibility. The synergistic interaction among components resolves the contradiction between accelerated drying and maintained versatility across different substrates.
3Loss of time
If existing drying additives are used, then some drying acceleration is achieved, but productivity improvement is insufficient
Solution Approach 1:
The patent employs a multi-component composite drying agent system with cobalt (6-14%), manganese (1-5%), and sulfur (1-5%) based agents working synergistically. This composite formulation achieves up to 50% faster drying times, translating to significant productivity improvements that exceed what single-component additives can deliver.
Solution Approach 2:
The invention optimizes multiple parameters simultaneously: cobalt content (6-14%), manganese content (1-5%), sulfur content (1-5%), and the ratios between components. This multi-parameter optimization achieves maximum drying acceleration (up to 50% time reduction) while ensuring broad applicability, thereby delivering substantial productivity improvements.

AI summary
A drying agent particularly suited for facilitating the drying of inks and paints includes a cobalt drier that is more than six percent cobalt by weight, and no more than fourteen percent cobalt by weight. In particular, the cobalt drier is twelve percent cobalt by weight. The drying agent can also include a manganese drier, tung oil, a water-activated drier, a two-way drier, and a lithographic overprint varnish. All ingredients can be present in the mixture at a concentration of one part by weight. The drying agent can be used with a variety of printing stock substrates, and may be used at significantly higher concentrations than prior art drying agents.
