Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
67 words
An improved fountain solution suitable for use in a lithographic offset printing press which solution contains between 0.5 and about 10% by volume of a mixture of a polyol and/or glycol ether partially soluble in water, partial solubility characterized as having a solubility in water at 20° C. of between about 0.99 to about 28 weight percent, and a polyol and/or glycol ether completely soluble in water.
Claim 2
Dependent Claim
67 words
An improved fountain solution suitable for use in a lithographic offset printing press which solution contains between 0.5 and about 10% by volume of a mixture of a polyol and/or glycol ether partially soluble in water, partial solubility characterized as having a solubility in water at 20° C. of between about 0.99 to about 28 weight percent, and a polyol and/or glycol ether completely soluble in water.
Claim 3
Dependent Claim
28 words
A fountain solution as defined in claim 1 wherein the polyol and/or glycol ether which is partially soluble in water comprises 2-ethyl-1,3-hexanediol, 3-hydroxy-2,2-dimethyl propyl 3-hydroxy-2,2-dimethylpropionate, 2-hexoxyethanol or 2-hexoxyethoxyethanol.
Claim 4
Dependent Claim
47 words
A fountain solution as defined in claims 1 or 2 wherein the polyol and/or glycol ether which is completely soluble in water is selected from one or more of propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, hexylene glycol, triethylene glycol, tetraethylene glycol, tripropylene glycol and 1,5-pentanediol.
Claim 5
Dependent Claim
36 words
A fountain solution as defined in claim 3 wherein the polyol and/or glycol ether which is completely soluble in water is selected from one or more of propylene glycol, dipropylene glycol, diethylene glycol and hexylene glycol.
Claim 6
Dependent Claim
46 words
A fountain solution as defined in claim 1 containing from about 0.08 to about 10 parts by volume of the polyol and/or glycol ether which is partially soluble in water per part by volume of the polyol and/or glycol ether which is completely soluble in water.
Claim 7
Dependent Claim
46 words
A fountain solution as defined in claim 5 containing from about 0.1 to about 0.25 parts by volume of the polyol and/or glycol ether which is partially soluble in water per part by volume of the polyol and/or glycol ether which is completely soluble in water.
Claim 8
Dependent Claim
42 words
A fountain solution as defined in claim 6 containing about 0.2 part by volume of the polyol and/or glycol ether which is partially soluble in water per part by volume of the polyol and/or glycol ether which is completely soluble in water.
Claim 9
Dependent Claim
42 words
A fountain solution as defined in claim 4 containing about 0.2 part by volume of the polyol and/or glycol ether which is partially soluble in water per part by volume of the polyol and/or glycol ether which is completely soluble in water.
