Abstract
Abstract A method for introducing a catalytic agent to lithographic printing ink. The catalytic agent is formulated into a catalytic fountain solution, transported via the fountain solution to the ink and infused therein to impart desired qualities to the ink. An organic titanate compound is used as a catalytic agent in conjunction with apparatus to initiate drying for preventing ink offset and producing clean, sharp printing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
68 words
A process for imparting catalytic, cross-linking qualities to ink in lithographic printing processes having a dampening system with a fountain solution, comprising: introducing a catalytic, cross-linking agent to the fountain solution, the agent being adapted to cross-link the ink upon exposure to ultraviolet radiation, infrared radiation or hot air; transporting the catalytic agent to the ink via the fountain solution; and, infusing the catalytic agent into the ink.
Claim 2
Dependent Claim
68 words
A process for imparting catalytic, cross-linking qualities to ink in lithographic printing processes having a dampening system with a fountain solution, comprising: introducing a catalytic, cross-linking agent to the fountain solution, the agent being adapted to cross-link the ink upon exposure to ultraviolet radiation, infrared radiation or hot air; transporting the catalytic agent to the ink via the fountain solution; and, infusing the catalytic agent into the ink.
Claim 3
Dependent Claim
26 words
A process as claimed in claim 1, further comprising exposing the ink to radiation or hot air after the ink has been printed on a substrate.
Claim 4
Dependent Claim
16 words
A process as claimed in claim 1, wherein the crosslinking agent is an organic titanate compound.
Claim 5
Dependent Claim
16 words
A process as claimed in claim 3, wherein the organic titanate compound is a titanate chelate.
Claim 6
Dependent Claim
61 words
In a lithographic printing process comprising the steps of dampening a printing plate with a fountain solution and inking said plate with lithographic printing ink, the improvement comprising introducing into the fountain solution a catalytic, cross-linking agent adapted to cross-link the ink upon exposure to ultraviolet radiation, infrared radiation or hot air, and infusing said catalytic, cross-linking agent into the link.
Claim 7
Dependent Claim
61 words
In a lithographic printing process comprising the steps of dampening a printing plate with a fountain solution and inking said plate with lithographic printing ink, the improvement comprising introducing into the fountain solution a catalytic, cross-linking agent adapted to cross-link the ink upon exposure to ultraviolet radiation, infrared radiation or hot air, and infusing said catalytic, cross-linking agent into the link.
Claim 8
Dependent Claim
26 words
A process as claimed in claim 5, further comprising exposing the ink to radiation or hot air after the ink has been printed on a substance.
Claim 9
Dependent Claim
16 words
A process as claimed in claim 5, wherein the crosslinking agent is an organic titanate compound.
Claim 10
Dependent Claim
16 words
A process as claimed in claim 7, wherein the organic titanate compound is a titanate chelate.
