[0008]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The present invention relates to an online printing system that transmits and receives paper surface data between one communication party and the other communication party via a communication line. Here, as the correspondent, the contractor,
The orderer, head office, branch office, etc. can be mentioned. In this embodiment, in order to facilitate understanding of the present invention, one correspondent will be referred to as an orderer and the other correspondent will be referred to as a contractor. FIG. 1 is a block diagram of an online printing system 1 which is an 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 contractors.
It is composed of 0 and.

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

The first printer 21 prints the paper surface 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 a pressure printing method. Plate making machine 23 is for producing a printing plate required for printing by the printer 22, the printing plate, the plate making machine 23, the first chart printing program 24c that page data and later edited by the 1PS24 Manufactured accordingly. In addition, the printing plate required for printing by the printing machine 22 is manufactured.

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

By the way, the size of the printed matter is not always
It does not become A4 size or smaller, such as A4 size or B5 size. Of course, the size of the printed matter may be larger than A4 size such as A1 size or B1 size. 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 calibrated. In this embodiment, A4 size or B
The printed matter divided into 5 sizes is referred to as a "bulk product" 60 (see FIG. 2), and the printed matter before the division is referred to as a "product" 70
(See FIG. 3). That is, the product 70 is a product to which a plurality of loose products 60 are attached. The bulk product 60 is printed by the first printer 21, and the product 70 is printed by the printing machine 22.

There are the following two reasons for distinguishing the printing device for printing the discrete product 60 from the printing device for printing the product 70. First, as the first reason, the price of a printing apparatus that prints a printed matter larger than A4 size (for example, an inkjet printer that can handle up to A1 size is from JPY 400,000 to JPY 60).
The price of a printing device that prints A4 size or smaller prints (for example, an inkjet printer that can handle up to A4 size) is about 10,000 yen, and a printing machine that requires a printing plate costs about 30 million yen to 500 million yen. From 30,000 yen to 4
It is much higher than the above (about 10,000 yen). The second reason is that when printing a large number of sheets, the pressureless printing method can print faster than the pressure printing method.

The first PS 24 is a digital camera (digita).
(l camera) 50 is for reading image data taken by the camera 50 and for editing paper surface data to be printed on a printed matter based on the read image data.
The first print profile 2 is previously stored in the first PS 24.
4a, a second print profile 24b, and a first chart print program 24c are stored (stored). First print profile 24a and second print profile 2
Reference numeral 4 b 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 the first printing profile 24
a is data created according to the characteristics of the printing machine 22, and the second printing profile 24b is the first printer 21.
It 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 the individual difference between the printing machine 22 and the first printer 21.

As described in the sections of "Prior Art" and "Problems to be Solved by the Invention", the characteristics of the first printer 21 and the characteristics of the printing machine 22 are usually different. Therefore, 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 bulk 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, the difference between the quality of the printed matter (bulk product 60) printed by the first PS 24 and the quality of the printed matter (product 70) printed by the printing machine 22 based on the first print profile 24a and the second print profile 24b. Is corrected, so that the quality of both the printed matters can be made the same. As a result, the quality of the product 70 can be evaluated by evaluating the quality of the bulk product 60. That is, even if the product 70 is not printed by the printing machine 22 that cannot print without using the printing plate, the bulk 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 proper (passed), it can be determined that the quality of the product 70 is also proper.

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

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

Here, the first printer 21, the printing machine 22 and other printing devices (including a second printer 34 which will be described later).
In general, four color ink materials of cyan, magenta, yellow and black are used as the ink material. Such first
The color control chart 61 is formed by arranging a plurality of substantially square enclosures 62 that are colored with a predetermined color. The enclosure 62 is colored by one of the four ink materials. Alternatively, a color obtained by mixing ink materials of a plurality of colors at a predetermined ratio is used.

The first spectrophotometer 25 is the "L-" of the first color control chart 61 printed on the bulk product 60.
ab "value (hereinafter, simply referred to as L-a-b value).
Is to measure. Here, L-a-b is 19
The International Commission on Illumination (CIE) as a unified standard in 31
The chromaticity coordinate of the CIE color space established by the above is expressed by a rational number, and is currently used as a standard in various fields. Even in Japan, JIS-Z8
729. "L" is the lightness, "a"
And “b” represent hue and saturation. That is, "L-
By using "ab", the color can be expressed objectively and quantitatively. Therefore, the L-a-b value of one color and the L-value of the other color
If the -ab value is the same, one color and the other color are always the same, regardless of the coloring method or coloring method.

Here, as described above, the first spectrophotometer 2
5 is to measure the L-a-b value of the first color control chart 61 printed on the bulk product 60.
Therefore, the measurement value (L-a-b value) of the first spectrophotometer 25
Is constant, it can be estimated that the quality of the printed matter (the bulk 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, at the end of the printed matter (product 70), the printing machine 2
2 prints the second color control chart 71. Similarly to the first color control chart 61, the second color control chart 71 also has a series of substantially square enclosures 72 that are colored with a predetermined color.

The second spectrophotometer 28 has the "L-a-b" of the second color control chart 71 (specifically, each enclosure 72 constituting the second color control chart 71) printed on the product 70. Value of (hereinafter, simply L-a
-B value. ) Is measured. Therefore, if the measurement value of the second spectrophotometer 28 (that is, the L-a-b value) is the same as the measurement value of the first spectrophotometer 25, the printing machine 22
It is possible to estimate that the color tone of the printed matter (product 70) printed by is the same as the color tone of the printed matter printed by the first printer 21. In addition, even if the color tone of the product 70 is different from that of the loose product 60, the second
The different cause can be estimated by the measurement value of the spectrophotometer 28. Specifically, whether the cause is a mechanical failure of the printing machine 22,
There is a factor in the ink material used in 2 or the above 2
It is possible to determine whether there is another factor other than one factor.

The first modem 26 modulates the page data edited by the first PS 24 and the Internet 10
Other device connected via 0 (for example, the second device 3
It also demodulates various data sent from 0). The first NCU 27 is for performing line control, and transmits, for example, the page data modulated by the first modem 26 to the second device 30 or the Internet 100.
It receives various data sent from other devices connected via the.

Next, the second device 30 will be described. Here, each second device 30 is assumed to have 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 a so-called “Internet” 100. The second device 30 includes a second NCU 31 and
The second modem 32, the second PS 33, and the second printer 3
4 and a third spectrophotometer 35. Second NCU3
Reference numeral 1 is for performing line control, and is for receiving various data transmitted from other devices connected via the Internet 100 and transmitting various data to such other device side. . 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 page data sent 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 paper surface data demodulated by the second modem 32 and transmits the read paper surface data to the second printer 34. In this second PS 33, the first print profile 24
a, the third print profile 33a, and the second chart print program 33b are stored (stored). Third
The print profile 33a is data according to the characteristic peculiar to the second printer 34, and is the first print profile 24a.
In addition, it is data for correcting the difference between the quality of the printed matter printed by the printing machine 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 the individual difference between the printing machine 22 and the second printer 34. Therefore, the quality of the printed matter printed by the second printer 34 can be made equal to 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 proper, it is said that a person who is involved in the ordering party or the ordering party goes back and forth between the ordering party and the ordering party. 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 printed by the first printer 21 (bulk product 60) or the printed matter printed by the printing machine 22 (product 70) is ordered. It is printed by the second printer 34 that the person involved in the ordering process is forced to perform a complicated operation of transporting (including mailing and home delivery; the same applies to the following) from the ordering party to the ordering party. It is possible to eliminate the compulsory operation of transporting the printed matter from the orderer side to the orderer side to the person concerned on the orderer side. As a result, it is possible to reduce labor costs, transportation costs, or transportation costs required for such traffic.

The second chart printing program 33b, like the first chart printing program 24c, is provided at the end of a printed matter (not shown) printed by the second printer 34,
It is a program for printing a third color control chart (not shown). The third spectrophotometer 35 is for measuring the L-a-b value of the third color control chart printed by the second printer 34. Therefore, if the measurement value of the third spectrophotometer 35 is the same as the measurement 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 presumed to be the same as the color tone. Consequently, it is possible to evaluate whether or not 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 proper, the color tone of the printed matter printed by the second printer 34 and the printed matter printed by the first printer 21 (the loose product 60 This is because the precondition is that the color tone is the same.

When the quality of the printed matter printed by the second printer 34 is evaluated to be defective, the cause of the defectiveness is estimated from the measurement value of the third spectrophotometer 35. You can do it. For example, whether the cause of the defect is a mechanical failure of the second printer 34, a cause of the ink material used in the second printer 34, or a cause other than the 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, first
The page data is edited by the PS 24 based on the image data. After editing the page data, the page data is transmitted to the first printer 21 by the first PS 24. Here, the paper surface 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. Conversion is performed based on the first print profile 24a and the second print profile 24b. After the paper surface data is transmitted to the first printer 21, the paper surface data is received by the first printer 21, and the received paper surface data is printed.

As described above, the first PS converts the paper surface data to be transmitted to the first printer 21 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 (bulk product 60) can be the same as that of the printed matter (product 70) printed by the printing machine 22. As a result, the quality of the product 70 can be evaluated by evaluating the quality of the bulk product 60. That is, the printing machine 2 that cannot print without using the printing plate.
Without printing the product 70 to be printed by 2, marks the first printer 21 can print without using a printing plate
The loose product 60 to be printed may be evaluated, and if the quality of the loose product 60 is proper, it can be determined that the quality of the product 70 is also proper.

When the paper data is transmitted to the first printer 21, the chart data is transmitted by the first PS 24 based on the first chart print 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 paper surface data. After the chart data is printed by the first printer 21, the first spectrophotometer 2
5, L- of the first color control chart 61
The ab value is measured.

In this way, the first spectrophotometer 25
Since the L-a-b value of the color control chart 61 is measured, the measured value of the first spectrophotometer 25 (L-a-b
If the value is constant, it can be estimated that the quality of the printed matter (the bulk 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 proper as a result of the judgment by the person concerned on the contractor side, the page data is transferred to the second PS33 side (the orderer side) by the first PS24. Sent. Second PS3
After sending the space data to the 3 side, the first modem 26
The transmitted paper surface data is modulated, and the first NCU 2
7, the modulated page data is transmitted via the Internet 100.

After the paper surface data is transmitted by the first NCU 27, the paper surface data is received by the second NCU 31. After receiving the page data by the second NCU 31,
The received paper surface data is demodulated by the modem 32. After demodulating the paper surface data, the demodulated paper surface data is read by the second PS 33. After reading the page data, the second PS33 changes the page data to the second page.
It is transmitted to the printer 34. Here, the second printer 34
The page data transmitted to the second PS33 is the second data.
Quality of printed matter printed by printer 34 and printing machine 2
The conversion is performed based on the first print profile 24a and the third print profile 33a so that the quality of the printed matter printed by 2 is the same. After the paper surface data is transmitted to the second printer 34, the paper surface data is received by the second printer 34, and the received paper surface data is printed. Second printer 3
After printing by 4, the quality of the printed matter printed by the second printer 34 and the printed matter printed by the first printer 21 (bulk product 60) between the person on the orderer side and the person on the orderer side. It is determined whether or not the quality is the same.

As described above, the second PS 33 allows the first print profile 24a and the third print profile 24b.
Based on the above, the paper surface data transmitted to the second printer 34 is converted. Therefore, the quality of the printed matter printed by the second printer 34 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, the orderer side or the person related to the orderer side is requested to
It is possible to eliminate the complicated operation of going back and forth between the orderer side and the orderer side.
Specifically, in order to make the quality of the printed matter printed by the second printer 34 proper, the printed matter printed by the first printer 21 (bulk product 60) or the printed matter printed by the printing machine 22 (product 70). The complicated operation of transporting the order from the orderer to the orderer is forced on the person involved on the orderer side, or the printed matter printed by the second printer 34 is transported from the orderer to the orderer. It is possible to solve the problem of compelling the ordering party to perform the complicated operation. As a result, it is possible to reduce labor costs, transportation costs, or transportation costs required for such traffic.

As a result of the judgment between the person on the contractor side and the person on the orderer side, the quality of the printed matter printed by the second printer 34 and the printed matter printed by the first printer 21 (the bulk product 60) If it is determined that the quality is not the same, the paper surface data is edited again by the first PS 24, and the edited paper surface data is edited by the second printer 34.
It is printed by.

On the other hand, as a result of the determination, the second printer 3
When it is determined that the quality of the printed matter printed by No. 4 and the quality of the printed matter printed by the first printer 21 (bulk product 60) are the same, the plate making machine 33 produces a printing plate and the printing machine 22 Thus, the desired number of products 70 are printed using the printing plate. When the product 70 is printed by the printing machine 22 in this way, 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 printing machine 22, the second spectrophotometer 28 is used to set the L-a-b of the second color control chart 71.
The value is measured.

In this way, the second spectrophotometer 28
Since the L-a-b value of the control chart 71 is measured, the measured value of the second spectrophotometer 28 (that is, L-a-b
If the 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 by the measurement value of the second spectrophotometer 28. Specifically, whether the cause is a mechanical failure of the printing machine 22 or an ink material used in the printing machine 22,
Alternatively, it is possible to determine whether there is another factor other than the above two factors.

When the page data is sent to the second printer 34, the second PS 33 sends the chart data based on the second chart printing program 33b stored in the second PS 33. After the chart data is transmitted 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 chart data is printed by the second printer 34, the third spectrophotometer 35 is used to set the L-a of the third color control chart.
-B value is measured.

Thus, by the third spectrophotometer 35,
Since the L-a-b 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. The color tone of the printed matter can be estimated to be the same as the color tone of the printed matter printed by the first printer 21. Consequently, it is possible to evaluate whether or not 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 proper, the color tone of the printed matter printed by the second printer 34 and the printed matter printed by the first printer 21 (the loose product 60 This is because the precondition is that the color tone is the same.

By the way, the second orderer (customer) side
When the device 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 incorrect. 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) and the quality of the printed matter printed by the second printer are the same. 33a is modified.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. Is something that can be easily guessed. Hereinafter, modified examples of this 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
Causes L of the printed matter printed by the first printer 21 to
The -ab value is measured, and the L-ab value of the printed matter printed by the second printer 34 is measured by the third spectrophotometer 35. However, it is not always necessary to measure the L-a-b value of the printed matter printed by the orderer on the orderer's side and the measurement of the L-a value of the printed matter on the orderer's side.
-The contractor does not have to measure the b value. That is, L of both the printed matter printed by the orderer and the printed matter printed by the contractor.
The -ab value may be measured on either the orderer side or the orderer side. In particular, if the orderer side performs the measurement, the cost of the device installed on the orderer side can be significantly reduced. This is because the number of orderers is usually larger than that of contractors, and
This is due to the high price of the spectrophotometer.

In this embodiment, the first NCU 27 sends the page data and the second NCU receives the page data.
It is performed by 31. However, it is not always necessary to send and receive the page data by the NCU, and depending on the situation, DSU (Digital Service Unit), TA
(Terminal Addapter) or another communication device such as a router may be used.

Here, to make sure that no misunderstanding occurs, the description will be made in the present specification by "printing paper surface data".
However, this description does not mean that the paper surface data itself is printed, but means an image, a character (including a symbol), or the like (based on the content of the paper surface data) that the paper surface data means. It is a thing.

The present invention also includes the following inventions.

When the printing system of the first printing unit is the pressure printing system, the first apparatus prints the pressureless printing unit and the quality of the printed matter printed by the pressureless printing unit. And a third storage unit that stores a second print profile that corrects a difference between the quality of the printed matter printed by the first printing unit, and the pressureless printing unit.
8. The online printing system A according to claim 1, wherein the paper surface data is printed based on the second print profile stored by the third storage means.

According to the online printing apparatus A thus constructed, the difference between the quality of the printed matter printed by the pressureless printing means and the quality of the printed matter printed by the first printing means is calculated by the third storage means. Since the second print profile to be corrected is stored, the quality of the printed matter can be evaluated or calibrated without printing by the first printing unit which is the pressure printing method. As a result, it is possible to reduce the cost required to evaluate or calibrate the quality of the printed matter, and it is possible to shorten the time required to perform such evaluation or proof. This is because printing by the pressure printing method requires manufacturing of a printing plate made of a metal material, resin material, stone material or paper material, whereas printing by the pressureless printing method requires manufacturing of the printing plate. It is due to not doing.
