A offset printing system for maintaining printability of offset printing ink. The offset printing system includes a suction pipe formed to fit within an ink fountain, a pump connected to a connecting pipe, a valve connected to the connecting pipe, a heater, a filter including a first filter and a second filter, a vacuum device including a disc and a stirrer, a heat exchanger connected to the connecting pipe and a discharge pipe formed to fit within the ink fountain.

BRIEF SUMMARY OF THE INVENTION
[0011] In view of the foregoing disadvantages inherent in the known types of offset printing systems now present in the prior art, the present invention provides a new offset printing system construction wherein the same can be utilized for maintaining printability of offset printing ink.
[0012] The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new offset printing system that has many of the advantages of the offset printing systems mentioned heretofore and many novel features that result in a new offset printing system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art offset printing systems, either alone or in any combination thereof.
[0013] To attain this, the present invention generally comprises a suction pipe formed to fit within an ink fountain, a pump able to connect to a connecting pipe, a valve connected to the connecting pipe, a heater, a filter including a first filter and a second filter, a vacuum device including a disc and a stirrer, a heat exchanger connected to the connecting pipe and a discharge pipe formed to fit within the ink fountain.
[0014] There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
[0015] In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
[0016] A primary object of the present invention is to provide an offset printing system that will overcome the shortcomings of the prior art devices.
[0017] A second object is to provide an offset printing system for maintaining printability of offset printing ink.
[0018] Another object is to provide an offset printing system that removes excessive etch content in an ink fountain.
[0019] An additional object is to provide an offset printing system that controls undesirable viscosity that may occur between etch solution and printing ink.
[0020] A further object is to provide an offset printing system that allows printing ink to remain at a constant temperature suitable for printing.
