The present invention relates to an ink manufacturing method and apparatus for producing ink, and more particularly, to an ink manufacturing method and apparatus for preparing ink by stirring and dispersing an ink composition material.

Print inks are made by mixing and dispersing materials and chemicals. Various kinds of inks are prepared according to the selection of the above materials. Various processes are performed to prepare the ink.

1 is a flowchart for explaining an ink manufacturing method according to the prior art.

Referring to FIG. 1, first, a colorant, a vehicle, and an auxiliary agent, which is a composition material of an ink, are prepared in a predetermined first container. The colorant imparts the color of the ink, and the vehicle carries the colorant to the printed object for fixation, and the auxiliary agent is added according to the use. The ink composition material contained in the vessel is stirred in a stirrer (S10).

The stirred ink composition material is transferred to the disperser through the suction hose of the disperser. The transferred ink composition material is dispersed in the disperser to minimize the particles of the colorant, and the colorant and the vehicle are well mixed. (S20) The dispersion is a temperature of the ink composition of 50 ° C. or less and the pressure of the disperser 1 kg / cm ³ or less is made in the state.

The dispersed ink composition material is moved back to the stirrer in the second container. It is stirred while adding a material for adjusting ink properties and colors to the ink composition material contained in the second container. Therefore, the composition of the ink composition material is adjusted to have the properties and colors required by the user. (S30)

When the composition of the ink composition is adjusted, a sample for inspecting the eligibility of the composition is collected.

Finally, the ink composition is filtered using a filter net, stored in a packaging machine, and then filled again to a designated weight in a product container. (S50, S60)

However, since the ink manufacturing method requires cleaning the first container and the second container, the stirrer, the disperser, the filter net, and the packing machine in each process, the cleaning process takes a lot of time, and the cleaning liquid used in the cleaning process is discarded as it is. Therefore, waste of material is large. In addition, the production system used for the manufacture of a large amount of ink is applied to the production of a small amount of ink as it is, the waste factor is proportional to the number of operations.

An object of the present invention for solving the above problems is to provide an ink manufacturing method that can shorten the manufacturing time by simplifying the work process.

Another object of the present invention for solving the above problems is to provide an ink manufacturing apparatus capable of manufacturing ink using the ink manufacturing method.

In order to achieve the above object of the present invention, the present invention provides an ink manufacturing method. The ink manufacturing method first stirs the material for forming the ink and then disperses the stirred ink composition material. Subsequently, the dispersed ink composition material is filtered and the ink and the physical properties and colors of the filtered ink are adjusted.

In order to achieve the above another object of the present invention, the ink manufacturing apparatus of the present invention has a stirrer for stirring a substance for forming the ink contained in the first container. A disperser is connected with the first container and mixes the stirred ink composition material. The first filter is detachably provided with a second container for containing the ink composition material mixed in the disperser, and filters the ink composition material supplied to the second container, and the second filter is detachable with the second container.
