Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the field of printing technology for performing high-precision printing. In particular, the present invention relates to a printing method for printing a data code such as audio information as a machine-readable high-definition pattern and a printed matter with a data code obtained by the printing method.

[0002]

2. Description of the Related Art It has been proposed to print a data code on a printed material to print, in addition to character / picture information, in particular, voice information (for example, JP-A-6-231466).
For example, it is apparent that the fun of the game, the learning effect, and the range are expanded by adding the voice information to the printed matter used in the game or the learning. For example, a picture-story show or picture-story show picture book will be more attractive if it can read out a special narrator and reproduce sound effects. In such a printed material, the printed portion of the data code generally has a high-definition pattern in order to secure an information amount. In addition, it is required that printing be performed with high accuracy in order to surely perform reading by the reading device. On the other hand, the print portion of the character / picture is also required to have high print reproducibility of high quality in appearance, or of quality consistent with the proof print.

In order to obtain a desired print reproducibility in a printed material, usually, detailed conditions are set from the first step of the pre-printing process. Then, in the printing step in the final step, the printing conditions are adjusted while inspecting the printed matter. For example, in an offset printing press, the print reproducibility can be controlled by adjusting the ink supply amount, dampening water supply amount, printing pressure, and the like (normally, the damping water supply amount and printing pressure are fixed). . Although the actual printing press behavior is not simple due to many conditions,
If the ink supply is set higher, the print density will increase,
When the dampening water supply amount is set high, the print density of the highlight from the halftone becomes low, and when the printing pressure is set high, the print density of the halftone becomes high by the dot gain. When the opposite setting is performed, the opposite tendency appears.

[0004]

However, it is not always necessary to adjust the same tendency in the data code printing portion and the character / picture printing portion. In general, it is sometimes required to adjust the tendency of the data code printing portion and the character / picture printing portion to be inconsistent or contradictory. In a printing press having a plurality of printing units, printing is performed immediately before the ink on the printing paper dries. Therefore, the ink printed on the printing paper in the upstream printing unit is transferred to the surface of the blanket cylinder of the downstream printing unit, and further transferred to the subsequent printing paper. At this time, even if the printing is normal, there is a slight change in the printing position, and halftone dots are printed in a multiplex manner.

Therefore, an object of the present invention is to provide a high-definition pattern, such as a data code printing portion, which is required to be printed with high accuracy, and a high quality, such as a character picture printing portion. Or a printed matter having a part where print reproducibility of the same quality as the proof printed matter is required,
That is, it is an object of the present invention to provide a printing method capable of appropriately printing a printed material having portions having different quality requirements, and a printed material obtained by the printing method.

[0006]

The above objects are achieved by the present invention described below. That is, the present invention provides a printing method for performing printing using a printing plate corresponding to n-color inks, where n is a natural number, wherein a predetermined printing area or a predetermined printing area for printing with a predetermined color ink of the n-color inks is used. A printing method of performing division on a halftone dot range and printing using a plurality of printing plates of the predetermined color ink corresponding to the division and printing plates of a color ink other than the predetermined color ink. According to the printing method of the present invention, when a printed material has portions having different quality requirements, a printing plate of a predetermined color ink for printing the different portions is divided into a plurality of printing plates corresponding to the different portions. Since the printing plates are printed in different printing units, independent adjustments can be made according to the quality requirements of the different portions. Therefore, there is provided a printing method capable of properly printing a printed material having a part having a different quality requirement.

The present invention is also a "printing method for performing printing using one of a plurality of printing plates of the predetermined color ink at the end of the printing". According to the printing method of the present invention, since one of the printing plates of the predetermined color ink is used at the end of overprinting in multicolor printing, the printing pattern of the printing plate is printed with multiple halftone dots. There is no. Therefore,
It is possible to print a portion having a high-definition pattern and requiring high-precision printing. The present invention is also a "printing method of performing printing of one of a plurality of printing plates of the predetermined color ink, and printing another printing plate after the ink film of the printing portion is dried". According to the printing method of the present invention, since the printing of another printing plate is performed after the ink film of the printing portion of the predetermined printing plate is dried, the printing pattern of the printing plate is printed with multiple halftone dots. There is no. Therefore, it is possible to print a portion having a high-definition pattern and requiring high-precision printing. Further, the present invention provides a method in which "the predetermined color ink is black (black)

In the figure, 1 is a character / pattern printing portion, and 2 is a data code printing portion. At least one of a character and a pattern is printed on the character / pattern printing portion 1. The data code printing portion 2 has an optically readable data code printed thereon. In the printed matter of the present invention shown in FIG. 1, printing is performed using separate printing plates for the character / picture printing portion 1 and the data code printing portion 2. That is, the character / pattern printing portion 1 and the data code printing portion 2 are printed in separate printing steps or in separate printing units.

FIG. 2 is a view showing that the character / picture printing portion 1 and the data code printing portion 2 are printed separately. In FIG. 2, reference numeral 3 denotes a printed matter obtained in a printing step of printing only the character / image print portion 1 in FIG.

n), red (M; magenta) and yellow (Y; yellow) inks and printing plates are used. Also 4
Is a printed matter obtained in a printing step of printing only the data code printing portion 2 in FIG. Printed matter 4 is ink (K
2)), and printing is performed using one color ink and a printing plate of black (K2; black2).

The black (K1) and the black (K2) have the same color. Therefore, by using the same ink (black ink) and using a printing plate having a printing pattern obtained by combining the printing pattern of the black (K1) plate of the printed matter 3 and the printing pattern of the black (K2) plate of the printed matter 4 One printing process (1
It is not impossible to complete with only one printing unit).
However, in the present invention, the printing process for obtaining the printed matter 3 shown in FIG. As a result, the character / image print portion 1 in which high-quality appearance and print reproducibility of a quality consistent with the proof print are required.
Independent and optimum printing conditions can be set for the data code printing portion 2 and the data code printing portion 2 which is required to be printed with high precision with a high definition pattern. As a result, the character / pattern printing portion 1 also becomes the data code printing portion 2
In both cases, it is possible to obtain a printed matter with good print reproduction.

The difference in the printed matter between the printed matter of the present invention and the conventional printed matter is not limited to the difference in quality between the character / picture print portion 1 and the data code print portion 2. If printing is performed in different printing processes even for a part using the same ink, the relative printing position of the part fluctuates at least within a normal range, and it is determined from that fact. be able to.

Next, the printing method of the present invention will be described. FIG. 3 is a flowchart showing a plate making process (a process of making a printing plate) in the present invention. The process of plate making in the printing method of the present invention will be described with reference to FIG. First, in step S1, plate making data is input to a plate making system. In the example shown in FIG. 3, it is assumed that the prepress data has three types: continuous tone, character / line drawing, and data code. The continuous tone plate making data includes plate making data corresponding to each of the four color inks of black (K), indigo (C), red (M), and yellow (Y). Contains the plate making data corresponding to one color of the ink of black (K), and the plate making data of the data code is one of the colors of the ink of black (K).
Plate making data corresponding to the color is included.

That is, the plate making data as a whole is composed of three types of plate making data printed with black (K) ink: continuous tone, character / line drawing, and data code, and plate making data printed by indigo (C) ink. , Platemaking data for printing with red (M) ink is one type of continuous tone, and platemaking data for printing with yellow (Y) ink is one type of continuous tone. That is, the plate making data as a whole has six individual plate making data corresponding to four color inks. Therefore, the printing plate corresponding to the four colors of ink,
It is generated in the process of plate making.

Next, in step S2, continuous tone, characters, and plate making data to be printed with black (K) ink are used.
It divides continuous tone plate making data and character / line drawing making data from line drawing and data code, and combines them. In other words, the continuous platemaking data and the character / line drawing platemaking data are arranged at predetermined positions to form one piece of combined platemaking data to be printed with black (K) ink. Next, in step S3, black (K) is obtained from the combined platemaking data.
Create a printing plate (K1 plate) for printing with ink. Also,
A printing plate (C) to be printed with indigo (C) ink from plate making data corresponding to indigo (C) ink in continuous tone plate making data
Red) (M) in the continuous tone plate making data
A printing plate (M plate) for printing with red (M) ink is prepared from the plate making data corresponding to the ink, and a printing plate (Y) for printing with yellow (Y) ink from the plate making data corresponding to the yellow (Y) ink.
Version).

Next, in step S4, from the continuous tone, character / line drawing, and data code, which are plate making data to be printed with black (K) ink,
The prepress data of the data code is divided into divided prepress data (specifying that the data code should be treated separately from the other in the prepress system). Next, in step S5, a printing plate (K2 plate) to be printed with black (K) ink is created from the divided plate making data (plate making data of the data code).

In this way, the K1 plate, C plate, M plate, and Y plate are obtained from the six individual plate making data corresponding to the four color inks.
Create five printing plates: plate and K2 plate. These five printing plates are printing plates corresponding to four color inks of black (K), indigo (C), red (M), and yellow (Y). In other words, the black (K) ink is divided into a predetermined area to be printed with the black (K) ink or a predetermined halftone dot range, that is, a character picture print portion and a data code print portion. Then, a printing plate of two black (K) inks corresponding to the division is obtained. Further, a printing plate of three color inks of indigo (C), red (M), and yellow (Y) other than the predetermined color ink is obtained.

The above-described process of obtaining a printing plate from each plate-making data is a simplified example. In fact, in the plate making system, register marks, gradation scales,
The process includes a process of synthesizing a color mark and the like, a process of correcting gradation, color reproduction, and the like. In addition, in the case of a plate making method in which a film master is closely printed on a printing plate (PS plate),
It is necessary to output the original film. Since these are well-known matters to those skilled in the art, their description will be omitted.

Next, a printing process in the printing method of the present invention will be described. FIG. 4 is a flowchart showing a printing process in the present invention. The printing process will be described with reference to FIG. FIG. 4A shows a character / image printing portion 1.
FIG. 4B is a diagram illustrating a printing process in which the data code printing portion 2 is printed after the printing of the data code is performed. FIG. 4B illustrates the printing process after the data code printing portion 2 is printed and the ink film of the printing portion is dried. FIG. 7 is a diagram illustrating a printing process of printing a character / picture print portion 2.

In FIG. 4A, first, in step S21, the black (K) ink portion of the character / image print portion 1 is printed using the K1 plate, and then in step S22, the C plate is used. The indigo (C) ink portion of the character pattern printing portion 1 is printed, and then in step S23, M
The red (M) ink portion of the character pattern printing portion 1 is printed using the plate, and then, in step S24, the yellow (Y) ink portion of the character pattern printing portion 1 is printed using the Y plate. . Finally, in step S25, K2
The data code printing portion 2 is printed using black (K) ink using the plate.

Each of the steps S21 to S25 can be performed in each of a plurality of printing units of one printing press. If the printing machine is a five-color machine (a printing machine having five printing units) or more, printing can be completed by passing the printing paper only once in the printing machine. When the printing machine is a four-color machine or less, a series of steps is divided and printing paper (including paper in the middle of printing)
Can be completed by passing it through a printing press multiple times. By adopting the printing method shown in FIG.
Since the printing of the data code printing portion 2 is performed at the end of the overprint, the data code printing portion 2 is not printed with the data code pattern in multiples. Therefore, it is possible to print the data code printing portion 2 which has a high definition pattern and is required to be printed with high accuracy.

Next, the printing method will be described with reference to FIG. First, in step S31, the data code printed portion 2 is printed using black (K) ink using the K2 plate, and then in step S32, it is determined whether the data code printed portion 2 has been dried. Is determined. If it is not dried, it stands by, and if it is dried, it proceeds to the next step S33. In step S33, the black (K) ink portion of the character / image printing portion 1 is printed using the K1 plate, and then in step S34,
The indigo (C) ink portion of the character pattern printing portion 1 is printed using the C plate, and then, in step S35, the red (M) ink portion of the character pattern printing portion 1 is printed using the M plate. Finally, in step S36, the yellow (Y) ink portion of the character / image printing portion 1 is printed using the Y plate.

Each of the steps S33 to S36 can be performed in each of a plurality of printing units of one printing press. If the printing machine is a four-color machine or more, printing can be completed by passing the printing paper only once in the printing machine. Step S31, S
32, when printing with an offset printing machine, usually, each printing unit is not provided with a drying device,
Printing is performed separately from steps S33 to S36. However, it is also possible to use a drying device inline, or to use a reactive ink that is dried (cured) by ionizing radiation such as ultraviolet rays or electron beams, and to use an ionizing radiation output device inline. In that case, all the steps S31 to S36 can be completed in one pass by one printing press. On the other hand, when printing with a gravure printing machine, each printing unit is usually provided with a drying device. Therefore, if the printing machine is a five-color printing machine or more, the printing paper is printed only once in the printing machine. The printing can be completed by passing through.

According to the printing method shown in FIG. 4 (2), the character code print portion is printed after the ink film of the data code print portion 2 dries, so that the data code print portion has multiple data code patterns. Will not be printed. Therefore, it is possible to print a data code printing portion that has a high-definition pattern and requires high-precision printing.

Next, the data code of the data code print portion 2 will be described. A two-dimensional dot code in which dots are two-dimensionally arranged can be printed on the data code printing portion. For example, by applying the present invention to a dot code described in JP-A-6-231466, a favorable print result can be obtained.

FIG. 5 is a diagram showing an example of a two-dimensional data code which can obtain a suitable printing result by applying the present invention. FIG.
, 51 is a fine dot having a diameter of about 50 μm. Such dots are two-dimensionally arranged, and data is formed by an arrangement pattern of the arranged dots. Each dot represents one bit of digital data. A portion where a halftone dot exists is "1", and a portion where it does not exist is "0".
Respectively. Then, for example, one byte (8 bits) of data is formed by two rows of dots arranged in a matrix.

FIG. 6 is a block diagram showing an example of a process of converting data into a dot arrangement pattern. For example,
To obtain an array pattern of dots of data "6A" in hexadecimal, first, in FIG. 6, the hexadecimal is expanded into a bit string to obtain "01101010" (S6).
1). Next, the bit string is converted into a bit matrix corresponding to the dot arrangement pattern (S62). In this example, since two columns of the matrix arrangement are assigned to one byte, a bit matrix as shown in FIG. 6A is obtained. Next, the bit matrix is converted into a dot arrangement pattern b (S6).
3). Finally, based on the data of the dot arrangement pattern b, it is output to a predetermined position of a film original used for plate making (S64).
