In recent years, the development of laser technology has been remarkable. In particular, the technology of freely deflecting laser light with a variable mask, a plotter mechanism (moving device in the XY-axis directions), a polygon mirror, etc. It is frequently used in the field of manufacturing, especially for engraving on metal surfaces, and its use has been rapidly advancing recently.

Accordingly, the present inventors have paid attention to this laser technology, provided an ink film layer in advance in the variable information recording portion, and irradiated the ink film layer with a laser to selectively scrape the ink film layer to obtain white ink. It has been found that the above object can be achieved by applying the variable information of the extracted image, and the present invention has been made.

That is, a form having variable information according to the present invention has a variable information description section in which an ink film layer is provided on a predetermined portion of a base material surface, and the variable information description section is irradiated with a laser beam by the laser irradiation. It is characterized in that the film layer surface is selectively scraped off and variable information including characters and numerals of a white image formed in advance is applied.

Further, in the method of forming variable information according to the present invention, a variable information description portion provided with an ink film layer on a predetermined portion of a substrate surface is irradiated with a laser beam controlled based on data input in advance. The laser irradiation is used to selectively scrape off the surface of the ink film layer, thereby forming variable information including characters and numerals of a white image.

According to the form having variable information of the present invention,
To print general information and ruled lines with normal printing ink using an offset printing machine, etc., and to perform solid printing of the ink film layer in the variable information description area with the same fill volume as these, inkjet printers and laser printers It is superior in cost as compared with the case where ink or toner such as is used, and since no ink film layer is formed at the time of variable information printing, print smear does not occur at all.

Further, the formation of the variable information is performed sequentially by changing the pattern of the variable information based on the input pattern data of the variable information to each unit form which is supplied in a continuous state and inputted to the laser irradiation device. , Easy and efficient.

It is a block diagram which shows the control method of a formation process.

First, as shown in FIG. 1, a form 1 having variable information of the present invention configured as a "membership certificate" is provided with general information 6 such as a title, a company name, and a description on the surface of the base material 2. And a variable information description section 4 provided with an ink film layer 3 formed of a desired printing ink.

A password and a member number, which are variable information 5 of a white image by laser irradiation, are printed on the variable information description section 4. It should be noted that the variable information description section 4 'in which the ink film layer 3 is not provided is also provided with variable information 5' for normal printing such as an address and a name by an ink jet printer.

As shown in FIG. 2, the variable information 5 is obtained by instantly burning or sublimating the portion of the ink film layer 3 which has been irradiated with the laser and selectively shaving off the ink color and the base material color exposed thereby. Characters and numerals of a white image are formed with a contrast of. In addition, the ink film layer in the present invention is applied with a normal printing ink such as a black-based, blue-based, red-based ultraviolet curable ink or an oxidative polymerization type ink. A near-infrared absorbing agent or the like may be added to improve the formation efficiency of variable information.

An embodiment of the method for forming variable information according to the present invention will be described below with reference to FIG. A continuous form W provided with a large number of feed holes H in the marginal portion is formed by connecting a large number of unit forms S via a folding / cutting sewing machine line. General information necessary for the "membership certificate" is printed in advance.

The feed hole H is engaged with a tractor pin of the tractor device T, and the continuous form W is transferred in a predetermined direction by driving the tractor device T. A variable information forming device is arranged on the transfer path of the continuous form W.

And two pairs of rotatable polarizing mirrors M, M, and the like.

As shown in the block diagram of FIG. 4, an encoder E for detecting the feed amount of the continuous form W is connected to the tractor device T. The encoder E converts the rotation amount of the tractor device T into a pulse signal. Feed amount is detected. When the converted pulse signal is sent to the control unit C, the control unit C sends the pattern data of the input variable information at the timing corresponding to the feed amount, that is, at the time when the variable information writing unit 4 reaches the laser irradiation position. , A control signal is issued to the laser light oscillator L and the drive unit of the polarizing mirrors M, M to control them. Further, an input device K such as a keyboard and a display device B such as a CRT are connected to the control unit C to input desired variable information pattern data and check operation conditions.
