[0026]

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention relates to an online printing system for transmitting and receiving paper data between one communicating party and another communicating party via a communication line. Here, as the communicator, the contractor,
An orderer, a head office, a branch, and the like can be cited. In this embodiment, in order to facilitate understanding of the present invention, one communicator will be described as an orderer and the other communicator will be described as a contractor. FIG. 1 is a block diagram of an online printing system 1 according to one embodiment of the present invention. As shown in FIG. 1, the online printing system 1 includes a first device 20 installed on the orderer side and a second device 3 installed on each of a plurality of contractor sides.
0.

The first device 20 includes a first printer 21, a printing machine 22, a plate making machine 23, and a first personal computer (hereinafter referred to as “PS”) 24. , A first spectrophotometer 25, a second spectrophotometer 28, a first modem 26
And a first network control unit (hereinafter referred to as "NC control unit"
U ". ) 27.

The first printer 21 prints the page data edited by the first PS 24 by a pressureless printing method. On the other hand, the printing machine 22 prints the paper surface data edited by the first PS 24 by the pressure printing method. The plate making machine 23 is a program for manufacturing a printing plate required for printing by the printing machine 22. The printing plate is composed of the sheet data edited by the first PS 24 and the first chart printing program
4c. Further, it is for producing a printing plate required for printing by the printing machine 22.

Here, the pressureless printing method is a method in which charged fine powder or fine mist (fog droplets) is used as ink, and this ink is adhered to electrostatic droplets on a printing surface.
This non-pressure printing method mainly includes an electrostatic flat plate printing method,
Electrostatic gravure printing, electrostatic stencil printing (also called electrostatic screen printing) printing, and inkjet printing
There is a method. On the other hand, the pressure printing method is a method of printing on paper by pressing ink applied to a printing plate. The pressure printing method mainly includes five methods: a relief printing method, a planographic printing method, an intaglio printing method, a stencil printing method, and a roller type printing method.

By the way, the size of the printed matter is not necessarily
The size is not smaller than A4 size such as A4 size or B5 size. Naturally, the size of the printed matter may be larger than A4 size such as A1 size or B1. When the size of the printed matter is larger than the A4 size, the printed matter is usually divided into A4 size or B5 size, and the paper surface data is edited or the color of the printed matter is corrected. In this embodiment, A4 size or B
Printed materials classified into five sizes are referred to as “loose products” 60 (see FIG. 2), and printed materials before being classified are referred to as “products” 70.
(See FIG. 3). That is, the product 70 has a plurality of loose products 60 imposed. The loose product 60 is printed by the first printer 21, and the product 70 is printed by the printing machine 22.

The reasons for distinguishing the printing device for printing the loose product 60 from the printing device for printing the product 70 are as follows. First, the first reason is that the price of a printing apparatus that prints a print of a size larger than A4 size (for example, an ink jet printer capable of handling up to A1 size from 400,000 yen to 60,000 yen).
A printing machine that requires a printing plate costs about 300,000 yen to about 500 million yen, but the price of a printing apparatus that prints printed matter of A4 size or less (for example, an inkjet printer that can handle up to A4 size) From 30,000 yen to 4
(About 10,000 yen). The second reason is that when printing a large number of sheets, printing can be performed faster by printing without pressure than by printing with pressure.

The first PS 24 is a digital camera (digita
l camera) 50 to read image data taken by the camera 50 and edit paper data to be printed on a printed matter based on the read image data.
The first PS 24 has a first print profile 2 in advance.
4a, a second print profile 24b, and a first chart printing program 24c are stored (stored). First print profile 24a and second print profile 2
4b is for correcting the difference between the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22, and includes a first print profile 24.
a is data created in accordance with the characteristics of the printing press 22, and the second printing profile 24b is
This is data created according to the characteristics of. That is, the first print profile 24a and the second print profile 24b
Is data for eliminating individual differences between the printing press 22 and the first printer 21.

As described in the “Prior art” and “Problems to be solved by the invention”, the characteristics of the first printer 21 and the characteristics of the printing press 22 are usually different. For this reason, there is a problem that the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22 are different. As a result, even if the quality of the loose product 60 printed by the first printer 21 is evaluated, the evaluation becomes irrelevant to the evaluation of the quality of the product 70 printed by the printing machine. .

However, as described above, the first PS
24, based on the first print profile 24a and the second print profile 24b, the difference between the quality of the printed matter (loose product 60) printed by the first PS 24 and the quality of the printed matter (product 70) printed by the printing machine 22. Is corrected, so that the quality of both printed materials can be made the same. By evaluating the quality of the loose product 60, the quality of the product 70 can be evaluated. That is, even if the product 70 is not printed by the printing machine 22 that cannot print without using the printing plate, the loose product 60 may be evaluated by the first printer 21 that can print without using the printing plate. If the quality of the product 60 is appropriate (passed), it can be determined that the quality of the product 70 is also appropriate.

The first chart printing program 24c is a program (printed product 6) printed by the first printer 21.
0), the first color control chart 61
(See FIG. 2), and a program for printing the second color control chart 71 (see FIG. 3) at the end of the printed matter (product 70) printed by the printing press 22. It is a program.

FIG. 2 is a plan view of the loose product 60. As shown in FIG. 2, an image 63 and a character 64 requested by the orderer are printed on the loose product 60 based on a predetermined arrangement, and the end of the loose product 60 has a first color. The control chart 61 is printed.

Here, the first printer 21, the printing press 22, and other printing devices (including a second printer 34 described later).
Usually uses four color ink materials of cyan, magenta, yellow and black as the ink material. The first
The color control chart 61 is formed of a series of substantially square-shaped enclosures 62 colored by a predetermined color, and the color applied to the enclosure 62 is one of the four ink materials. Alternatively, a color in which a plurality of ink materials are mixed at a predetermined ratio is used.

The first spectrophotometer 25 reads “L−L” of the first color control chart 61 printed on the loose product 60.
ab ”(hereinafter, simply referred to as“ Lab value ”).
Is to measure. Here, Lab is 19
The International Commission on Illumination (CIE) as a global standard in 1951
Is a rational number representing the chromaticity coordinates of the CIE color space established by the International Standard, and is currently used as standard in various fields. In Japan, JIS-Z8
729. "L" is brightness, "a"
And “b” represent hue and saturation. That is, "L-
If "ab" is used, the color can be expressed objectively and quantitatively. Therefore, the L-ab value of one color and the L-ab value of another color
If the -ab value is the same, one color and the other color will always be the same color, regardless of the color coloring method or coloring method.

Here, as described above, the first spectrophotometer 2
5 is for measuring the Lab value of the first color control chart 61 printed on the loose product 60.
Therefore, the measurement value (Lab value) of the first spectrophotometer 25
Is constant, it can be estimated that the quality of the printed matter (loose product 60) printed by the first printer 21 is also constant.

FIG. 3 is a plan view of the product 70. As shown in FIG. 3, a printing machine 2 is provided at the end of the printed matter (product 70).
2, the second color control chart 71 is printed. Similarly to the first color control chart 61, the second color control chart 71 is also formed of a series of substantially square enclosures 72 colored with a predetermined color.

The second spectrophotometer 28 reads “Lab” of the second color control chart 71 printed on the product 70 (specifically, each enclosure 72 constituting the second color control chart 71). (Hereinafter simply referred to as La
-B value. ) Is measured. Therefore, if the measured value of the second spectrophotometer 28 (that is, the Lab value) is the same as the measured value of the first spectrophotometer 25, the printing machine 22
Can be estimated that the color tone of the printed matter (product 70) printed by the first printer 21 is the same as the color tone of the printed matter printed by the first printer 21. Also, when the color tone of the product 70 is different from the color tone of the loose product 60, the second
The different cause can be estimated from the measurement value of the spectrophotometer 28. Specifically, whether the cause is a mechanical failure of the printing press 22 or not,
Whether there is a factor in the ink material used in 2 or
It is possible to determine whether there is another factor different from one factor.

The first modem 26 modulates the page data edited by the first PS 24,
0 (for example, the second device 3)
0) is demodulated. The first NCU 27 is for performing line control. For example, the first NCU 27 transmits paper data modulated by the first modem 26 to the second device 30,
And various data transmitted from other devices connected via the Internet.

Next, the second device 30 will be described. Here, each of the second devices 30 has the same configuration, and only one second device 30 will be described. The second device 30 is a device installed on the orderer side, and is connected to the first device 20 via the so-called “Internet” 100. The second device 30 includes a second NCU 31,
A second modem 32, a second PS 33, and a second printer 3
4, a third spectrophotometer 35. 2nd NCU3
Reference numeral 1 denotes a circuit for performing line control, for receiving various data transmitted from another device connected via the Internet 100, and transmitting various data to the other device. . The page data sent from the first device 20 is received by the second NCU 31. The second modem 32 demodulates various data received by the second NCU 31 and modulates various data transmitted by the second NCU 31. The paper data transmitted from the first device 20 and received by the second NCU 31 is demodulated by the second modem 32.

The second PS 33 reads the page data demodulated by the second modem 32 and transmits the read page data to the second printer 34. The second PS 33 includes the first print profile 24
a, a third printing profile 33a, and a second chart printing program 33b are stored (stored). Third
The print profile 33a is data corresponding to characteristics unique to the second printer 34, and is the first print profile 24a.
At the same time, it is data for correcting the difference between the quality of the printed matter printed by the printing press 22 and the quality of the printed matter printed by the second printer 34. That is, the first print profile 24a and the third print profile 33a are data for eliminating individual differences between the printing press 22 and the second printer 34. Therefore, the quality of the printed matter printed by the second printer 34 can be made the same as the quality of the printed matter printed by the printing machine 22. Consequently, by evaluating the quality of the printed matter printed by the second printer 34, the quality of the product 70 printed by the printing machine 22 can be evaluated.

Further, in order to make the quality of the printed matter printed by the second printer 34 appropriate, it is necessary for a person concerned on the orderer side or the orderer side to move between the orderer side and the orderer side. It is possible to eliminate the need for complicated operations. Further, in order to make the quality of the printed matter printed by the second printer 34 appropriate, the printed matter (the loose product 60) printed by the first printer 21 or the printed matter (the product 70) printed by the printing machine 22 is received. The second printer 34 prints out that a complicated operation of transporting (including mailing and home delivery; the same applies to the following) from the client side to the orderer side is imposed on the party on the order receiving party side. Thus, it is possible to prevent a complicated operation of transporting the printed matter from the orderer side to the orderer side from being imposed on the person concerned on the orderer side. As a result, labor costs and transportation costs required for such traffic, or transportation costs can be reduced.

The second chart printing program 33b is, like the first chart printing program 24c, attached to the end of a printed matter (not shown) printed by the second printer 34.
This is a program for printing a third color control chart (not shown). The third spectrophotometer 35 is for measuring the Lab value of the third color control chart printed by the second printer 34. Therefore, if the measured value of the third spectrophotometer 35 is the same as the measured value of the first spectrophotometer 25, the color tone of the printed matter printed by the second printer 34 is the same as that of the printed matter printed by the first printer 21. It can be estimated that the color tone is the same. As a result, it is possible to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate. This is because, in order to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate, the color tone of the printed matter printed by the second printer 34 and the printed matter (the loose product 60 This is because it is a precondition that the color tones are the same.

If the quality of the printed matter printed by the second printer 34 is poor as a result of the evaluation, the cause of the failure is estimated based on the value measured by the third spectrophotometer 35. You can do it. For example, is the cause of the failure caused by a mechanical failure of the second printer 34, the ink material used in the second printer 34, or another factor different from the above two factors? Can be determined.

Next, the operation of the online printing system 1 configured as described above will be described. First, the first P
At S24, the image data taken by the digital camera 50 is read. After reading the image data,
The page data is edited by the PS 24 based on the image data. After editing the page data, the first PS 24 transmits the page data to the first printer 21. Here, the page data transmitted to the first printer 21 is processed by the first PS 24 so that the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22 are the same. The conversion is performed based on the first print profile 24a and the second print profile 24b. Then, after the page data is transmitted to the first printer 21, the page data is received by the first printer 21, and the received page data is printed.

As described above, the paper data transmitted to the first printer 21 is converted by the first PS on the basis of the first print profile 24a and the second print profile 24b, so that the first printer 21 prints. The quality of the printed matter (loose product 60) can be the same as the quality of the printed matter (product 70) printed by the printing press 22. By evaluating the quality of the loose product 60, the quality of the product 70 can be evaluated. That is, a printing machine 2 that cannot print without using a printing plate
The first printer 21 can print the product 70 without using a printing plate without printing the product 70 using the second product 60.
Can be evaluated, and if the quality of the loose product 60 is appropriate, it can be determined that the quality of the product 70 is also appropriate.

When the page data is transmitted to the first printer 21, the first PS 24 transmits the chart data based on the first chart printing program 24c stored in the first PS 24. After the chart data is transmitted by the first PS 24, the chart data is received by the first printer 21, and the received chart data is printed together with the page data. After printing the chart data by the first printer 21, the first spectrophotometer 2
5, L- of the first color control chart 61
The a-b value is measured.

As described above, the first spectrophotometer 25 uses the first
Since the Lab value of the color control chart 61 is measured, the measured value (Lab) of the first spectrophotometer 25 is measured.
If the value is constant, it can be estimated that the quality of the printed matter (loose product 60) printed by the first printer 21 is also constant.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention relates to an online printing system for transmitting and receiving paper data between one communicating party and another communicating party via a communication line. Here, as the communicator, the contractor,
An orderer, a head office, a branch, and the like can be cited. In this embodiment, in order to facilitate understanding of the present invention, one communicator will be described as an orderer and the other communicator will be described as a contractor. FIG. 1 is a block diagram of an online printing system 1 according to one embodiment of the present invention. As shown in FIG. 1, the online printing system 1 includes a first device 20 installed on the orderer side and a second device 3 installed on each of a plurality of contractor sides.
0.

The first device 20 includes a first printer 21, a printing machine 22, a plate making machine 23, and a first personal computer (hereinafter referred to as "PS") 24. , A first spectrophotometer 25, a second spectrophotometer 28, and a first modem 26
And a first network control unit (hereinafter referred to as "NC control unit"
U ". ) 27.

The first printer 21 prints the page data edited by the first PS 24 by a pressureless printing method. On the other hand, the printing machine 22 prints the paper surface data edited by the first PS 24 by the pressure printing method. The plate making machine 23 is a program for manufacturing a printing plate required for printing by the printing machine 22. The printing plate is composed of the sheet data edited by the first PS 24 and the first chart printing program
4c. Further, it is for producing a printing plate required for printing by the printing machine 22.

Here, the non-pressure printing system is a system in which charged fine powder or fine mist (fog droplets) is used as ink, and the ink is adhered to electrostatic droplets on a printing surface.
This non-pressure printing method mainly includes an electrostatic flat plate printing method,
Electrostatic gravure printing, electrostatic stencil printing (also called electrostatic screen printing) printing, and inkjet printing
There is a method. On the other hand, the pressure printing method is a method of printing on paper by pressing ink applied to a printing plate. The pressure printing method mainly includes five methods: a relief printing method, a planographic printing method, an intaglio printing method, a stencil printing method, and a roller type printing method.

By the way, the size of the printed matter is not necessarily
The size is not smaller than A4 size such as A4 size or B5 size. Naturally, the size of the printed matter may be larger than A4 size such as A1 size or B1. When the size of the printed matter is larger than the A4 size, the printed matter is usually divided into A4 size or B5 size, and the paper surface data is edited or the color of the printed matter is corrected. In this embodiment, A4 size or B
Printed materials classified into five sizes are referred to as “loose products” 60 (see FIG. 2), and printed materials before being classified are referred to as “products” 70.
(See FIG. 3). That is, the product 70 has a plurality of loose products 60 imposed. The loose product 60 is printed by the first printer 21, and the product 70 is printed by the printing machine 22.

There are two reasons for distinguishing the printing device for printing the loose product 60 from the printing device for printing the product 70 as described above. First, the first reason is that the price of a printing apparatus that prints a print of a size larger than A4 size (for example, an ink jet printer capable of handling up to A1 size from 400,000 yen to 60,000 yen).
A printing machine that requires a printing plate costs about 300,000 yen to about 500 million yen, but the price of a printing apparatus that prints printed matter of A4 size or less (for example, an inkjet printer that can handle up to A4 size) From 30,000 yen to 4
(About 10,000 yen). The second reason is that when printing a large number of sheets, printing can be performed faster by printing without pressure than by printing with pressure.

The first PS 24 is a digital camera (digita
l camera) 50 to read image data taken by the camera 50 and edit paper data to be printed on a printed matter based on the read image data.
The first PS 24 has a first print profile 2 in advance.
4a, a second print profile 24b, and a first chart printing program 24c are stored (stored). First print profile 24a and second print profile 2
4b is for correcting the difference between the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22, and includes a first print profile 24.
a is data created in accordance with the characteristics of the printing press 22, and the second printing profile 24b is
This is data created according to the characteristics of. That is, the first print profile 24a and the second print profile 24b
Is data for eliminating individual differences between the printing press 22 and the first printer 21.

As described in the “Prior art” and “Problems to be solved by the invention”, the characteristics of the first printer 21 and the characteristics of the printing press 22 are usually different. For this reason, there is a problem that the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22 are different. As a result, even if the quality of the loose product 60 printed by the first printer 21 is evaluated, the evaluation becomes irrelevant to the evaluation of the quality of the product 70 printed by the printing machine. .

However, as described above, the first PS
24, based on the first print profile 24a and the second print profile 24b, the difference between the quality of the printed matter (loose product 60) printed by the first PS 24 and the quality of the printed matter (product 70) printed by the printing machine 22. Is corrected, so that the quality of both printed materials can be made the same. By evaluating the quality of the loose product 60, the quality of the product 70 can be evaluated. That is, even if the product 70 is not printed by the printing machine 22 that cannot print without using the printing plate, the loose product 60 may be evaluated by the first printer 21 that can print without using the printing plate. If the quality of the product 60 is appropriate (passed), it can be determined that the quality of the product 70 is also appropriate.

The first chart printing program 24c is a program (printed product 6) printed by the first printer 21.
0), the first color control chart 61
(See FIG. 2), and a program for printing the second color control chart 71 (see FIG. 3) at the end of the printed matter (product 70) printed by the printing press 22. It is a program.

FIG. 2 is a plan view of the loose product 60. As shown in FIG. 2, an image 63 and a character 64 requested by the orderer are printed on the loose product 60 based on a predetermined arrangement, and the end of the loose product 60 has a first color. The control chart 61 is printed.

Here, the first printer 21, the printing press 22, and other printing devices (including a second printer 34 described later).
Usually uses four color ink materials of cyan, magenta, yellow and black as the ink material. The first
The color control chart 61 is formed of a series of substantially square-shaped enclosures 62 colored by a predetermined color, and the color applied to the enclosure 62 is one of the four ink materials. Alternatively, a color in which a plurality of ink materials are mixed at a predetermined ratio is used.

The first spectrophotometer 25 reads “L−L” of the first color control chart 61 printed on the loose product 60.
ab ”(hereinafter, simply referred to as“ Lab value ”).
Is to measure. Here, Lab is 19
The International Commission on Illumination (CIE) as a global standard in 1951
Is a rational number representing the chromaticity coordinates of the CIE color space established by the International Standard, and is currently used as standard in various fields. In Japan, JIS-Z8
729. "L" is brightness, "a"
And “b” represent hue and saturation. That is, "L-
If "ab" is used, the color can be expressed objectively and quantitatively. Therefore, the L-ab value of one color and the L-ab value of another color
If the -ab value is the same, one color and the other color will always be the same color, regardless of the color coloring method or coloring method.

Here, as described above, the first spectrophotometer 2
5 is for measuring the Lab value of the first color control chart 61 printed on the loose product 60.
Therefore, the measurement value (Lab value) of the first spectrophotometer 25
Is constant, it can be estimated that the quality of the printed matter (loose product 60) printed by the first printer 21 is also constant.

FIG. 3 is a plan view of the product 70. As shown in FIG. 3, a printing machine 2 is provided at the end of the printed matter (product 70).
2, the second color control chart 71 is printed. Similarly to the first color control chart 61, the second color control chart 71 is also formed of a series of substantially square enclosures 72 colored with a predetermined color.

The second spectrophotometer 28 reads “Lab” of the second color control chart 71 printed on the product 70 (specifically, each enclosure 72 constituting the second color control chart 71). (Hereinafter simply referred to as La
-B value. ) Is measured. Therefore, if the measured value of the second spectrophotometer 28 (that is, the Lab value) is the same as the measured value of the first spectrophotometer 25, the printing machine 22
Can be estimated that the color tone of the printed matter (product 70) printed by the first printer 21 is the same as the color tone of the printed matter printed by the first printer 21. Also, when the color tone of the product 70 is different from the color tone of the loose product 60, the second
The different cause can be estimated from the measurement value of the spectrophotometer 28. Specifically, whether the cause is a mechanical failure of the printing press 22 or not,
Whether there is a factor in the ink material used in 2 or
It is possible to determine whether there is another factor different from one factor.

The first modem 26 modulates the page data edited by the first PS 24,
0 (for example, the second device 3)
0) is demodulated. The first NCU 27 is for performing line control. For example, the first NCU 27 transmits paper data modulated by the first modem 26 to the second device 30,
And various data transmitted from other devices connected via the Internet.

Next, the second device 30 will be described. Here, each of the second devices 30 has the same configuration, and only one second device 30 will be described. The second device 30 is a device installed on the orderer side, and is connected to the first device 20 via the so-called “Internet” 100. The second device 30 includes a second NCU 31,
A second modem 32, a second PS 33, and a second printer 3
4, a third spectrophotometer 35. 2nd NCU3
Reference numeral 1 denotes a circuit for performing line control, for receiving various data transmitted from another device connected via the Internet 100, and transmitting various data to the other device. . The page data sent from the first device 20 is received by the second NCU 31. The second modem 32 demodulates various data received by the second NCU 31 and modulates various data transmitted by the second NCU 31. The paper data transmitted from the first device 20 and received by the second NCU 31 is demodulated by the second modem 32.

The second PS 33 reads the page data demodulated by the second modem 32 and transmits the read page data to the second printer 34. The second PS 33 includes the first print profile 24
a, a third printing profile 33a, and a second chart printing program 33b are stored (stored). Third
The print profile 33a is data corresponding to characteristics unique to the second printer 34, and is the first print profile 24a.
At the same time, it is data for correcting the difference between the quality of the printed matter printed by the printing press 22 and the quality of the printed matter printed by the second printer 34. That is, the first print profile 24a and the third print profile 33a are data for eliminating individual differences between the printing press 22 and the second printer 34. Therefore, the quality of the printed matter printed by the second printer 34 can be made the same as the quality of the printed matter printed by the printing machine 22. Consequently, by evaluating the quality of the printed matter printed by the second printer 34, the quality of the product 70 printed by the printing machine 22 can be evaluated.

Further, in order to make the quality of the printed matter printed by the second printer 34 appropriate, the orderer or the orderer is referred to a person who goes back and forth between the orderer and the orderer. It is possible to eliminate the need for complicated operations. Further, in order to make the quality of the printed matter printed by the second printer 34 appropriate, the printed matter (the loose product 60) printed by the first printer 21 or the printed matter (the product 70) printed by the printing machine 22 is received. The second printer 34 prints out that a complicated operation of transporting (including mailing and home delivery; the same applies to the following) from the client side to the orderer side is imposed on the party on the order receiving party side. Thus, it is possible to prevent a complicated operation of transporting the printed matter from the orderer side to the orderer side from being imposed on the person concerned on the orderer side. As a result, labor costs and transportation costs required for such traffic, or transportation costs can be reduced.

The second chart printing program 33b is, like the first chart printing program 24c, attached to the end of a printed matter (not shown) printed by the second printer 34.
This is a program for printing a third color control chart (not shown). The third spectrophotometer 35 is for measuring the Lab value of the third color control chart printed by the second printer 34. Therefore, if the measured value of the third spectrophotometer 35 is the same as the measured value of the first spectrophotometer 25, the color tone of the printed matter printed by the second printer 34 is the same as that of the printed matter printed by the first printer 21. It can be estimated that the color tone is the same. As a result, it is possible to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate. This is because, in order to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate, the color tone of the printed matter printed by the second printer 34 and the printed matter (the loose product 60 This is because it is a precondition that the color tones are the same.

If the quality of the printed matter printed by the second printer 34 is evaluated as being poor, the cause of the failure is estimated from the value measured by the third spectrophotometer 35 if the quality of the printed matter is poor. You can do it. For example, is the cause of the failure caused by a mechanical failure of the second printer 34, the ink material used in the second printer 34, or another factor different from the above two factors? Can be determined.

Next, the operation of the online printing system 1 configured as described above will be described. First, the first P
At S24, the image data taken by the digital camera 50 is read. After reading the image data,
The page data is edited by the PS 24 based on the image data. After editing the page data, the first PS 24 transmits the page data to the first printer 21. Here, the page data transmitted to the first printer 21 is processed by the first PS 24 so that the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22 are the same. The conversion is performed based on the first print profile 24a and the second print profile 24b. Then, after the page data is transmitted to the first printer 21, the page data is received by the first printer 21, and the received page data is printed.

As described above, the page data transmitted to the first printer 21 is converted by the first PS based on the first print profile 24a and the second print profile 24b, so that the first printer 21 prints. The quality of the printed matter (loose product 60) can be the same as the quality of the printed matter (product 70) printed by the printing press 22. By evaluating the quality of the loose product 60, the quality of the product 70 can be evaluated. That is, a printing machine 2 that cannot print without using a printing plate
The first printer 21 can print the product 70 without using a printing plate without printing the product 70 using the second product 60.
Can be evaluated, and if the quality of the loose product 60 is appropriate, it can be determined that the quality of the product 70 is also appropriate.

When the page data is transmitted to the first printer 21, the chart data is transmitted by the first PS 24 based on the first chart printing program 24c stored in the first PS 24. After the chart data is transmitted by the first PS 24, the chart data is received by the first printer 21, and the received chart data is printed together with the page data. After printing the chart data by the first printer 21, the first spectrophotometer 2
5, L- of the first color control chart 61
The a-b value is measured.

As described above, the first spectrophotometer 25 makes the first
Since the Lab value of the color control chart 61 is measured, the measured value (Lab) of the first spectrophotometer 25 is measured.
If the value is constant, it can be estimated that the quality of the printed matter (loose product 60) printed by the first printer 21 is also constant.

If the quality of the printed matter printed by the first printer 21 is appropriate as a result of the determination by the parties involved on the order receiving side, the first PS 24 sends the page data to the second PS 33 side (the orderer side). Sent. 2nd PS3
After transmitting the page data to the third side, the first modem 26
The transmitted page data is modulated and the first NCU 2
7, the modulated page data is transmitted via the Internet 100.

After the first NCU 27 transmits the page data, the second NCU 31 receives the page data. After receiving the page data by the second NCU 31, the second
The modem 32 demodulates the received page data. After the demodulation of the page data, the demodulated page data is read by the second PS 33. After reading the page data, the second PS 33 outputs the page data to the second PS 33.
Sent to printer 34. Here, the second printer 34
The page data transmitted to is transmitted to the second PS 33 by the second PS 33.
Quality of Printed Material Printed by Printer 34 and Printing Machine 2
2 is converted based on the first print profile 24a and the third print profile 33a so that the quality of the printed matter printed by the second print profile becomes the same. Then, after the page data is transmitted to the second printer 34, the page data is received by the second printer 34, and the received page data is printed. Second printer 3
After the printing by 4, the quality of the printed matter printed by the second printer 34 and the printed matter (loose product 60) printed by the first printer 21 between the party on the orderer side and the party on the orderer side. It is determined whether or not the quality is the same.

As described above, the second PS 33 uses the first print profile 24a and the second print profile 24b.
Is converted into the page data transmitted to the second printer 34 on the basis of. Therefore, the quality of the printed matter printed by the first printer 21 and the quality of the printed matter printed by the printing machine 22 can be made the same. Consequently, by evaluating the quality of the printed matter printed by the second printer 34, the quality of the product 70 printed by the printing machine 22 can be evaluated. Also,
In order to make the quality of the printed matter printed by the second printer 34 appropriate, to the orderer side or the orderer side related parties,
It is possible to eliminate a complicated operation of moving back and forth between the contractor and the orderer.
Further, in order to make the quality of the printed matter printed by the second printer 34 appropriate, the printed matter (loose product 60) printed by the first printer 21 or the printed matter (product 70) printed by the printing machine 22 is received. To complicate the operation of transporting the order from the orderer to the orderer, or to transport the printed matter printed by the second printer 34 from the orderer to the orderer. It is possible to eliminate imposing an unnecessary operation on the person concerned on the orderer side. As a result, labor costs and transportation costs required for such traffic, or transportation costs can be reduced.

As a result of the judgment between the related party on the order receiving side and the related party on the ordering party side, the quality of the printed matter printed by the second printer 34 and the printed matter printed by the first printer 21 (loose product 60) If the quality is not the same, the page data is edited again by the first PS 24, and the edited page data is transmitted to the second printer 34.
It is printed by.

On the other hand, as a result of the determination, the second printer 3
If it is determined that the quality of the printed matter printed by the printer 4 and the quality of the printed matter (loose product 60) printed by the first printer 21 are the same, a printing plate is manufactured by the plate making machine 33 and the printing machine 22 is printed. Thus, the desired number of products 70 are printed using such a printing plate. When the product 70 is printed by the printing machine 22 in this manner, the printing machine 2
2, the second color control chart 71 is printed based on the second chart printing program 22a. After printing by the printer 22, the second spectrophotometer 28 uses the Lab of the second color control chart 71.
The value is measured.

As described above, the second spectrophotometer 28
Since the Lab value of the control chart 71 is measured, the measured value of the second spectrophotometer 28 (that is, the Lab value) is obtained.
Value) is the same as the measurement value of the first spectrophotometer 25, the color tone of the printed matter (product 70) printed by the printing machine 22 is the same as the color tone of the printed matter printed by the first printer 21. It can be estimated. Further, even when the color tone of the product 70 is different from the color tone of the loose product 60, the different cause can be estimated from the measurement value of the second spectrophotometer 28. Specifically, whether such a cause is due to a mechanical failure of the printing press 22, whether there is a factor in the ink material used in the printing press 22,
Alternatively, it is possible to determine whether there is another factor other than the two factors.

When the page data is transmitted to the second printer 34, the chart data is transmitted by the second PS 33 based on the second chart printing program 33b stored in the second PS 33. After the transmission of the chart data by the second PS 33, the second printer 34
The chart data is received, and the received chart data is printed together with the page data. After the printing of the chart data by the second printer 34, the third spectrophotometer 35 outputs the La of the third color control chart.
The -b value is measured.

As described above, the third spectrophotometer 35
Since the Lab value of the third color control chart is measured, if the measured value of the third spectrophotometer 35 is the same as the measured value of the first spectrophotometer 25, it is printed by the second printer 34. It can be assumed that the color tone of the printed matter is the same as the color tone of the printed matter printed by the first printer 21. As a result, it is possible to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate. This is because, in order to evaluate whether the quality of the printed matter printed by the second printer 34 is appropriate, the color tone of the printed matter printed by the second printer 34 and the printed matter (the loose product 60 This is because it is a precondition that the color tones are the same.

By the way, the second orderer (customer) side
When the apparatus 30 is installed, or when the second printer 34 on the orderer side is replaced, the adjustment of the third print profile 33a is insufficient, and the quality of the printed matter printed by the second printer is determined to be inappropriate. turn into. In this case, the third print profile is set so that the quality of the printed matter printed by the first printer 21 (or the printed matter printed by the printing machine 22) is the same as the quality of the printed matter printed by the second printer. 33a is modified.

As described above, the present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the gist of the present invention. Can be easily inferred. Hereinafter, a modified example of the present embodiment will be described.

In this embodiment, the first spectrophotometer 25 is installed on the orderer side, while the third spectrophotometer 35 is installed on the orderer side. Then, the first spectrophotometer 25
, The L of the printed matter printed by the first printer 21
The -ab value is measured, and the third spectrophotometer 35 measures the Lab value of the printed matter printed by the second printer 34. However, it is not always necessary for the orderer to measure the Lab value of the printed matter printed on the orderer side, and to measure the Lab value of the printed matter printed on the orderer side.
It is not necessary that the measurement of the -b value be performed by the contractor. That is, the L of both the printed matter printed on the orderer side and the printed matter printed on the orderer side
The -ab value may be measured on one of the orderer side and the contractor side. In particular, if the measurement is performed on the orderer side, the cost of the equipment installed on the orderer side can be significantly reduced. This is due to the fact that the number of orderers is usually larger than the number of contractors, and
This is due to the high price of the spectrophotometer.

In this embodiment, the first device 20 is installed on the orderer side, and the second device 30 is installed on the orderer side. However, it is not always necessary that the first device 20 be installed on the orderer side and the second device 30 be installed on the orderer side. For example, the first device 20 may be installed on the orderer side, and the second device 30 may be installed on the orderer side. When there is a head office and a branch, the first device 20 is installed at the head office and
The device 30 may be installed on the branch side, or the first device 20
May be installed on the branch side, and the second device 30 may be installed on the head office side.
