Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides thick printing from a transfer blanket to a substrate by controlling the adhesion state of printing ink on a gravure plate cylinder and supplying the printing ink so as to penetrate deeply into the character or pattern plate portion. The present invention relates to a printing method and apparatus capable of printing.
[0002]
[Prior art]
Conventionally, in order to make the ink swell on the printing surface, a method of mixing the foaming agent into the printing ink and printing it, and raising it by the foaming action after printing, or a method called bump printing There has been a method in which a powder that expands when heated is adhered to a printed matter, and the powder is dissolved and expanded by heating to excite the image.
[0003]
[Problems to be solved by the invention]
In any of the above-mentioned conventional examples, any of the above-described examples has a technical feature in that a special foaming action or a heat expansion action is generated in the printing ink or the printed material so that the printing portion is raised.
[0004]
However, when the ink itself is foamed or expanded, there is a problem that the original color effect of the ink becomes a problem and the expanded portion may be worn away.
[0005]
The present invention does not devise the ink itself so as to eliminate the above-mentioned difficulties, but mainly has a feature in the offset action when transferring from the gravure plate cylinder to the transfer blanket, and the purpose and The object of the present invention is to provide a printing method and a printing apparatus capable of realizing a thick printing surface by controlling a state in which ink is supplied to a plate of a gravure plate cylinder.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, an anilox roll for solid printing with an ink having the property of repelling printing ink in the first invention, a gravure plate cylinder in contact with the anilox roll, and a transfer blanket in contact with the gravure plate cylinder are provided. Before supplying the printing ink to the surface of the gravure plate cylinder, the anilox roll supplies the ink having the property of repelling the printing ink to the surface of the gravure plate cylinder to perform solid printing, and the printing ink supplied to the gravure plate cylinder is supplied. The printing method was such that the thickness of the ink, which was deeply penetrated and attached to characters or patterns, could be felt.
[0007]
In the second invention, an anilox roll for solid printing with an ink having a property of repelling printing ink, a gravure plate cylinder in contact with the anilox roll, and a transfer blanket in contact with the gravure plate cylinder are provided. After supplying the ink having the property of repelling the printing ink to a portion outside the printing target, the printing ink is supplied to the characters or patterns on the gravure plate cylinder. .
[0008]
According to a third aspect of the present invention, there is provided the printing apparatus according to the second aspect, wherein the thickness of the printing ink supplied to the plate portion such as a character or pattern of the gravure plate cylinder is about 0.3 mm.
[0009]
[Action]
In the first invention, the ink having the property of repelling printing ink is solid-printed only on the peripheral portion of the plate portion by an anilox roll so as not to affect the plate portion such as characters or patterns. The effect of repelling ink can be obtained. Therefore, the printing ink on the gravure plate cylinder can be repelled without affecting the original characters and patterns on the gravure plate cylinder, and the printing ink can penetrate into the deep groove which has not been seen in the past.
[0010]
When the ink is transferred to the printing substrate, the thick ink transferred to the transfer blanket is transferred as it is, so that thick printing can be realized.
[0011]
According to a second aspect of the present invention, there is provided an apparatus for realizing the above method, wherein an anilox roll for solid printing with an ink having a property of repelling printing ink, a gravure plate cylinder in contact with the anilox roll, and a gravure plate cylinder in contact with the gravure plate cylinder A transfer blanket is provided to supply the printing ink to the characters or patterns on the gravure plate cylinder after supplying the printing ink with the property of repelling the printing ink only to the periphery of the characters or patterns or other objects to be printed.
[0012]
In the third invention, since the thickness of the printing ink supplied to the plate portion is set to about 0.3 mm, there is a swelling which has not been seen in the past, and the thickness can be sufficiently felt at the tip of the hand.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention is characterized in that before printing ink is supplied to the gravure plate cylinder, solid printing is performed on the periphery of the plate portion using an anilox roll.
As an ink having the property of repelling printing ink, an oil-based ink is a synthetic resin ink which easily transfers from the anilox roll surface to the gravure plate cylinder and has a quick drying property.
[0014]
【Example】
Hereinafter, the configuration will be described with reference to the drawings shown as examples.
[0015]
In FIG. 1, 1 is an anilox roll, and 2 is a transfer blanket. Reference numeral 3 denotes a gravure plate cylinder provided between the anilox roll 1 and the transfer blanket 2 and in contact with each other.
[0016]
4 shown in FIG. 2 is an example of anilox. Very fine lattices or halftone dots are formed, and a thin ink-repelling ink is applied only to the periphery of the plate of the gravure plate cylinder (see FIG. 4).
[0017]
Reference numeral 5 denotes a printing substrate. Reference numeral 6 denotes an ink for repelling printing ink, and reference numeral 7 denotes a plate portion for characters and patterns. Reference numeral 8 denotes a printing ink, which can realize a depth of about 0.3 mm as shown in FIG.
[0018]
FIG. 3 shows a state in which printing ink is supplied to a plate portion such as a character or a pattern in the gravure plate cylinder 3. FIG. 4 is a partially enlarged cross-sectional view of the gravure plate cylinder 3 and schematically shows the state of penetration of ink.
[0019]
Compared to a conventional printing ink layer of about 6μ, printing can be performed up to a thickness of 0.3mm, and the printing surface has become more prominent. Therefore, when the printing surface is touched with a finger, the thickness can be sufficiently felt.
[0020]
【The invention's effect】
The present invention is characterized by an offset effect that occurs at the time of transfer from the gravure plate cylinder to the transfer blanket, and when the printing ink is supplied to the plate of the gravure plate cylinder, an ink that repels the printing ink by the anilox is provided on the periphery. Therefore, a printing method and apparatus capable of realizing a deep plate and providing a thick printing surface could be provided.
