Embodiment approach 1
[0041] Such as figure 1 As shown, the printing apparatus 300 according to Embodiment 1 includes a control unit 301 , a storage unit 302 , a head 303 , an ink storage unit 304 containing printing ink 340 , an anilox roller 310 , a plate cylinder 320 , and a printing table 330 .
[0042] The control unit 301 has a CPU (Central Processing Unit) and the like, and performs overall functions of the printing apparatus 300, such as ejection of printing ink from the head 303 described later and driving of the anilox roller 310 and the plate cylinder 320. control.
[0043] The storage unit 302 is a storage device composed of ROM (Read Only Memory), RAM (Random Access Memory, Random Access Memory), and the like. The storage unit 302 stores, for example, programs executed by the control unit 301 , data related to printing patterns based on plates on the plate cylinder 320 , and the like. In addition, the storage unit 302 operates, for example, as a working memory when the control unit 3...
Embodiment approach 2
[0092] Such as Figure 11 As shown, the printing apparatus 400 according to Embodiment 2 is different from the printing apparatus 300 according to Embodiment 1 which has one head 303 , having two heads 303 a and 303 b. In addition, in the following description, the same code|symbol is attached|subjected to the same structure as embodiment already demonstrated, and the detailed description is abbreviate|omitted.
[0093] A printing ink container 304a is connected to the head 303a. The printing ink 340 having the same predetermined concentration as in the first embodiment is stored in the printing ink storage portion 304a. The head 303a is arranged so as to be able to eject the printing ink 340 toward the anilox roller 310 similarly to the first embodiment.
[0094] The printing ink container 304b is connected to the head 303b. Printing ink having a concentration lower than that of the printing ink 340 is stored in the printing ink storage portion 304b. The head 303b is arra...
Embodiment approach 3
[0100] Such as Figure 12 As shown, the printing apparatus 500 of the third embodiment is different from the printing apparatus 300 of the first embodiment in that the anilox plate 350 in which the anilox roll 310 of the first embodiment is rolled out into a planar shape is used. In addition, the structures not described above will be described below.
[0101] In this embodiment, the anilox plate 350 is a printing ink container formed in a rectangular plate-like body. On one main surface of the anilox plate 350 , that is, on the surface facing the plate cylinder 320 , a mesh 351 is formed as a shallow concave portion corresponding to the mesh 311 of the anilox roll 310 . The mesh 351 is provided to have a predetermined depth, pattern, etc. according to printing conditions and the like.
[0102] The anilox plate table 360 is a table-shaped member for fixing the anilox plate 350 . The anilox plate table 360 is configured to be movable at least in the Y-axis direction in t...
