Description:
BACKGROUND OF THE INVENTION 
   The present invention relates to a print management server, printing management system and printing method for management of the printing of image data exchanged via a communications network. 
   The following describes the prior art procedures for printing a photograph taken by a customer with reference to  FIG. 11 : 
     FIG. 11  is a schematic diagram representing the physical distribution and procedures thereof in prior art printing. As shown in  FIG. 11 , the photograph taken by a customer is printed mainly by the following three methods: 
   In the first method, a customer  100  takes a negative to an agent such as a photo studio  101  or the like, and requests his or her photograph to be printed. It is exposed, developed and printed at a large-sized photofinishing lab  102 . According to this method, negatives collected by multiple agents can be exposed and developed at a large-sized photofinishing lab  102 . In this case, however, the negative is handed over to the large sized photofinishing lab  102  through the photo studio  101  from the customer  100  before printing is completed. The completed print must also be handed over to the customer  100  through the photo studio  101  from the large sized photofinishing lab  102 . Several days are required from the request of printing to completion of printing. 
   In the second method, the customer  100  takes a negative directly to a small sized minilab  103  capable of exposure and development, without the intervention of photo studio  101  or other agent. According to this method, printing is completed several hours after the arrival of the negative brought by the customer  100 , since exposure and development apparatuses are installed at the minilab. 
   In the third method, an image data photographed with a digital camera or the like by a customer  100 , for example, is sent to a specified server  104  or the like via the communications network, and is exposed and developed by a photofinishing lab  105  equipped with digital exposure and development departments. According to this method, the customer need not visit a shop to request printing. Image data can be sent to a server  04  managed by a company providing printing services via the network. This is a convenient method. 
   According to three prior art methods for requesting printing described above, the customer  100  can use a negative or digital image data to request printing. 
   In all the aforementioned cases, a photosensitive material to be used for printing is produced by a photosensitive material manufacturer  106 , and is marketed via a physical distribution/sales company  107 . This requires physical distribution costs, which in turn raises printing costs. 
   The aforementioned large sized photofinishing lab  102 , minilab  103  or the like engaged in exposure and development normally keeps certain numbers of photosensitive materials in stock to meet possible urgent requirements. Keeping them in stock will result in cost increase due to stocktaking of photosensitive materials, and will also result in secular deterioration of photosensitive materials. 
   Generally, the photosensitive material comprises multiple compositions of coating liquids which, in turn, comprise a pigment forming coupler and photosensitive silver halide lactic acid produced through crystal growth, chemical sensitizing and pigmentary sensitizing of silver halide particles, which, if required, further contains organic solvent of high boiling point, pigment image stabilizer, ultraviolet ray absorber, fogging inhibitor and binder, as well as surfactant, liquid viscosity regulator, irradiation inhibiting die, silver development inhibitor, fluorescent whitener, membranous quality modifier and hardening agent. Multiple layers of the aforementioned composition of coating liquids are simultaneously applied to a continuously traveling plastic covering paper support, resin film or other similar support, which is dried to produce the photosensitive material. Accordingly, the photosensitive material must be managed and stored with extreme care under certain environmental conditions. If not, secular change will occur and the required performances will be exhibited. 
   However, in the printing system described above, the photosensitive material manufacturer  106 , manufacturer engaged in exposure and development and stores ( 102 ,  103 ,  105 , etc.) are independently of one another. The photosensitive material is subjected to various environments before it is used after having been produced, and it is not protected against secular deterioration in the prior art. To reduce the period of storage and to solve this problem, it may be possible to procure the photosensitive material every time an order is placed, but this method requires enormous physical distribution costs, with the result that printing services cannot be provided at low price.

As shown in  FIG. 7 , the development department terminal  70  contains a CPU 71  (order data receiving means, printing management information receiving means), RAM 72 , memory apparatus  73 , recording medium  74 , communications unit  75  and terminal apparatus  76 . All units except for the recording medium  74  are connected by the path  77 . Functions of each unit are the same as those of the management server  30 , manufacturing department terminal  50  and exposure department. To avoid duplication, their detailed description will be omitted. The recording medium  74  has an order acceptance database  731  for storing the printing management information including the order detail data sent from the management server  30 . 
   The following describes the operation of the printing management system  1  of the present invention arranged in the aforementioned configuration with reference to the block diagram in  FIG. 1  and flow chart in  FIG. 1 : 
   The overall operation flow the printing management system  1  of the present invention will be described first with reference to the flow chart of Chart  7 : 
   Printing order placement and reception processing is carry out between the customer terminal  20  operated by customer  2  and management server  30  (Step S 1 ). 
   Data transmission and reception is processed via LAN  8  regarding the management of printing among the management server  30 , exposure department terminal  60  and development department terminal  70  based on the printing order placement and reception in Step S 1 . (Step S 2 ) 
   Digital exposure processing is carried out to provide digital exposure on the photosensitive material delivered by the manufacturing department in the exposure department  6  having received via the exposure department terminal  60  the data on the management of printing processing including the image data of the customer  2  in the aforementioned Step S 2  (Step S 3 ). 
   The aforementioned digitally exposed photosensitive material is then sent to the development department  7 , and is subjected to development based on the printing management data received by the management server  30  via the development department terminal  70  (Step S 4 ). 
   Upon completion of printing, the completed print is handed over to the customer  2  and settlement of accounts is processed for printing charges. All the operations in the printing system according to the present invention are now complete (Step S 5 ). 
   When the completed print is handed over to the customer, it can be mailed to the address specified by the customer  2 , or can be handed over to the customer at a convenience store nearest to the customer, a department store, a super-market, a kiosk at the station, a bookstore or an agent such as a camera shop. Printing charges are paid according to the method for settlement of accounts selected by the customer  2  in the processing of order acceptance in Step S 1 ; for example, by receiving the product in return for payments, transfer of money to a specified account, subtraction of the amount from the customer&#39;s bank account, settlement of credit card accounts via the Internet or settlement by electronic money. 
   Further, the management server  30  processes printing order acceptance in the Step S 1  with a plurality of customer terminals  20 , etc., and computes the photosensitive material production volume and time period thereof in conformity to the details of the order such as the volume of order. 
   It also works with the manufacturing department terminal  50  to process photosensitive material production control to issue the instructions on photosensitive material production and delivery to the manufacturing department  5  (Step S 1 A). 
   The manufacturing department  5  produces the photosensitive material based on the production and delivery instruction coming from the management server  30  via the manufacturing department terminal  50 , and delivers the product to the exposure department  6  (Step S 2 A). 
   The following gives the details of the aforementioned description: 
   First, printing order placement and reception processed between the customer terminal  20  and management server  30  in Step S 1  will be described with reference to the flow chart in  FIG. 8 . 
   The customer  2  as an operator of the customer terminal  20  accesses such an open communications network  4  as the Internet, and uses the input unit  24  or the like to enter a predetermined URL. Taking such a similar step, the aforementioned customer accesses the management server  30 , and requests the management server  30  to provide the order screen data of printing order service (Step S 101 ). 
   Having received the request signal for the order screen data of printing order service via the communications unit  35 , the CPU 31  of the management server  30  causes the order acceptance program  331 B stored in the application database  331  to be stored into the RAM 32  so that this program starts up. Then control of the following operations is started in conformity to the program  331 B. The CPU 31  sends the print service order screen data stored in the application database  331  to the customer terminal  20  via the communications unit  35  (Step S 102 ). 
   Then the customer terminal  20  receives the aforementioned order screen data via the communications unit  26 , and the CPU 21  of the customer terminal  20  causes this order screen data to be displayed on the display unit  23  (Step S 103 ). 
   Here items to be selected and specified by the customer  2  on the aforementioned screen include the number of prints, print size, quality on printed surface such as luster and silk, as well as type of prints such as thickness. For example, custom order data on image data color compensation, trimming, superimposition of images and letters, enlargement, reduction, etc. can be ordered by the customer  2  if desired. 
   This order screen includes the items to be specified, including the customer&#39;s name, contact point, e-mail address, delivery method, time of delivery and means for payment. The delivery method is defined as a method for handing the finished prints over to the customer. For example, any of the following positions can be selected for handing the finished prints over to the customer; a convenience store, a super-market, a department store, a bookstore, a kiosk at the station or an agent such as a camera shop. The account settlement method can be selected from the following, for example; by receiving the product in return for payments, transfer of money to a specified account, subtraction of the amount from the customer&#39;s bank account, settlement of credit card accounts via the Internet or settlement by electronic money. 
   Under this condition, customer  2  uses the input unit  24  to select or enter these items, and attach the image data to be printed. When the customer  2  has clicked on the button or the like, the CPU 21  of the customer terminal  20  sends the order data including the application data and attached image data to the management server  30  (Step S 104 ). 
   Having received the aforementioned application data, the CPU 31  of management server  30  creates an order detail verification screen data and sends it to the customer terminal  20  (Step S 105 ). 
   Then an order detail verification screen (not illustrated) for verification of order detail data and application data appears on the display unit  23  of the customer terminal  20  (Step S 106 ). So the customer  2  uses an input unit  24  to select an order button or cancel button. When it has detected a signal indicating that the order button has been pressed (Step S 107 : Yes), the CPU 21  sends an order signal to the management server  30  and proceeds to Step S 108 . When it has detected a signal indicating that the cancel button has been pressed (Step S 107 : No), the CPU 21  proceeds to Step S 103 . 
   In Step S 108 , the CPU 31  of the management server  30  receives the order signal sent from the customer terminal  20  and creates an order acceptance screen data. It then sends it to the customer terminal  20  and process to Step S 110 . 
   Then the CPU 21  of the terminal  20  causes the order acceptance screen received from the management server  30  to be displayed on the display unit  23  (Step S 109 ). 
   In the meantime, customer information such as order detail data and application data, and image data having received from the customer terminal  20  are loaded into the customer database  332  in Step S 110  by the CPU 31  of the management server  30 . Processing of printing order placement and reception is not complete (Step S 1 ). 
   In the aforementioned processing of printing order placement and reception, it is also possible to arrange a configuration which permits simulation of superimposition wherein letters and other images are superimposed on the image data by the operation of the customer terminal  20 . In this case, the management server  30  is provided with a system which can be started on the WWW and which is capable of image processing with the customer terminal  20 . 
   With reference to the flow chart of  FIG. 9 , the following describes processing of photosensitive material production control (Step S 1 A) to be implemented between the management server  30  and manufacturing department terminal  50  in response to printing order placement and reception in the aforementioned Step S 1 : 
   Having received printing order from the customer terminal  20  in Step S 1 , the CPU 31  of the management server  30  reads out a computing program  333 B stored in the production control database  333 , and loads it into the RAM 32  where it is started to computer then production control information on photosensitive material production volume, production time period, etc. in conformity to this program (Step S 1 A 1 ). 
   To put it more specifically, computing of production control information is that the data on the volume of printing and delivery time requested by the customer  2  is compared with the inventory volume of photosensitive materials, and the optimum inventory is computed based on the given basic data including the data on the period of use of photosensitive materials without performances being deteriorated. Then computation is made to find out the production volume of photosensitive materials that can be used up within the period of use of photosensitive materials, and time of production in such a way that this optimum inventory level is reached. To put it in greater details, computation is made using the basic data such as the parameter on the trend of photosensitive materials to be consumed as predetermined in conformity to the data on past order volumes, or the parameter on the permissible period of use dependent on changes in performance based on such storage conditions as temperature and humidity of photosensitive materials. The data on such storage conditions as temperature and humidity of photosensitive materials is measured by a thermometer and hygrometer in the warehouse where photosensitive materials are stored. The measured storage conditions are sent to the management server  30  via the manufacturing department terminal  50 . Then the CPU 31  of the management server  30  sets up the period of use according to the received data on storage conditions. 
   In this case, the CPU 31  creates the production control information including the production volume and production time period, and the instruction on the delivery to the exposure department  5  for each category of the photosensitive material. 
   Then the photosensitive material production control information and the instruction on the delivery created according to the aforementioned computation sent to the manufacturing department terminal  50  via the communications unit  35  by the CPU 31  of the management server  30  (Step S 1 A 2 ). 
   Then the manufacturing department terminal  50  receives the aforementioned photosensitive material production control information and the instruction on the delivery (Step S 1 A 3 ). The operation in Step SA 1  of  FIG. 7  terminates with reception of this information. It is also possible to arrange an configuration where transmission and reception of production and delivery information between this management server  30  and manufacturing management department terminal  50  are processed for each order from the customer terminal  20  or at each of the predetermined separated periods. 
   Photosensitive material production is processed according to the photosensitive material production control information and delivery instruction information received from the management server  30  via the manufacturing department terminal  20  in the aforementioned manufacturing department  5  (Step S 2 A). 
   This photosensitive material production process is the same as the photosensitive material production process commonly adopted in the industry. To put it more specifically, the silver halide photosensitive material represented by color paper and color film is manufactured is manufactured as follows: Preparation is made of photosensitive silver halide emulsion produced by growth of silver halide particles into crystals chemical sensitization and pigmentary sensitization, a pigment forming coupler, a solvent with high boiling point (if required), a pigment image stabilizer, an ultraviolet ray absorbing agent, a fogging inhibitor, a dispersant comprising such a lipophilic composition as pigment absorption improving agent, hydrophilic colloid represented by gelatin as a binder, surfactant, liquid viscosity regulator, irradiation inhibiting dye, silver development inhibitor, fluorescent whitening agent, membrane physical property improver and a plurality of coating liquid compositions containing an additive such as hardening agent as required. A slide hopper method or curtain coating method is used to carry out simultaneous coating on multiple layers on a plastic covering paper support for continuous traveling of the aforementioned coating liquid composition and a support such as plastic film. The support can be made of any material; it can be paper coated with polyethylene and polyethylene terephthalate, paper support made of natural pulse or synthetic pulp, polyvinyl chloride sheet, polypropylene which may contain white pigment, polyethylene terephthalate support and baryta paper. 
   Photosensitive materials are manufactured by drying the support with multiple layers coated simultaneously. After having been coating and drying, they are cut into the size conforming to the required product form and are lightproof packaged. Then they are sent to the exposure department  6 . 
   Further, photosensitive materials may be stored at a managed temperature or humidity. In order to cross link the binder and to get a desired film strength, it may be preferable that the photosensitive materials are stored at a managed temperature or humidity for a predetermined time in any one of the processes between coating and drying of these photosensitive materials and development thereof. 
   It is also possible to arrange such a configuration that the manufacturing department  5  and exposure department  6  are connected by one and same line, and light proof processing can be omitted when photosensitive materials are delivered. This will make it possible to omit the step of packaging, whereby time and effort as well cost can be cut down. 
   When photosensitive material production at the manufacturing department  5  and delivery at the exposure department  6  have been completed in the manner described above, photosensitive material production and delivery termination data is created by the manager of the manufacturing department  5  or the like using the input unit  55  of the manufacturing department terminal  50 . At the same time, the inventory data is updated. The aforementioned production and delivery termination data and updated inventory data are sent to the management server  30  in conformity to control by the CPU 5  of the manufacturing department terminal  50  (Step S 1 A 4 ). Having received the data, the management server  30  rewrites the inventory data  333 C based on the aforementioned data (Step S 1 A 5 ). 
   The following describes the processing of printing management (Step S 2 ) among the management server  30 , exposure department terminal  60  and development department terminal  70  in  FIG. 7 , with reference to the flow chart in  FIG. 10 . 
   In Step S 201 , having received printing order from the customer terminal  20  in Step S 1 , the CPU 31  of the management server  30  reads out a scheduled management program  331 C stored in the application database  331 , and loads it into the RAM 32 , where it is started to create the printing management information including the scheduled printing management information in conformity to the program  331 C (Step S 201 ). 
   The printing management information is the instruction data to instruct the exposure management department  6  and development management department  7  to implement printing based on the details of the customer  2  order. It includes such order data such the number of prints and custom order as well as image data, in addition to the work schedule information which is set to meet delivery requirements specified by the customer  2 . 
   Then the CPU 3  of the management server  30  sends the aforementioned printing management information to the exposure department terminal  60  and development department terminal  70  (Step S 202 ). 
   The CPU 61  of exposure department terminal  60  receives the printing management information, which is loaded in the order acceptance database (Step S 203 ). Printing management information received at this time is accompanied by the image data sent from customer  2 . 
   At the same time, the CPU 71  of the development department terminal  70  receives printing management information and loads it into the acceptance database  731  (Step S 204 ). Processing of printing management is terminated with the completion of this step (Step S 2 ). 
   The following describes processing of digital exposure (Step S 3  in  FIG. 7 ) implemented by the exposure department  6  based on the aforementioned printing management information: It should be noted that this digital exposure process is the same as the commonly practiced method, and is not restricted to the method described below. 
   Since the image data sent from the customer  2  is handled in a digital form, the following methods are available for exposure based on digital image data: In one method, an image is formed on the CRT (cathode ray tube) and the formed image is again formed on the photosensitive material supplied from the manufacturing department  5 , whereby printing is performed. In another method, the digital image is displayed on the liquid crystal display element on the transmissive or reflective LCD. After having been converted as required, light from a light source is led to the liquid crystal display element and the light of the transmitted or reflected image is printed on the photosensitive material. In still another method, a DMD element is used instead of a liquid crystal display element. After having been color-converted as required, light from the light source is led to the DMD display element, and the light of reflected image is printed on the photosensitive material. These methods are characterized by simultaneous exposure of the two-dimensional range (plane surface). A further method is a so-called scanning exposure method wherein one-dimensional range (linear range) is exposed so that scanning is performed by changing the intensity of laser beam based on the digital information. Digital exposure is carried out according to these methods. 
   Scanning exposure by beam is commonly performed by a combination of linear exposure by beam (raster exposure: horizontal scanning) and relative traveling of a photosensitive material in the direction vertical to this linear exposure (vertical scanning). For example, the photosensitive material is fixed on the outer periphery or inner periphery of a cylindrical drum, and the drum is rotated with beam kept applied thereto, whereby horizontal scanning is performed. At the same time, the light source is moved vertically in the direction of drum rotation, whereby vertical scanning is performed. Alternatively, the reflected beam is made to scan horizontally in the direction of polygon mirror rotation by applying beam to the rotating polygon mirror (horizontal scanning); at the same time, the photosensitive material is moved vertically with respect to the direction of polygon rotation, whereby vertical scanning is performed. These polygon methods are frequently employed. Further, when use of made of an exposure apparatus wherein light sources are arranged in an array in excess of the width of the photosensitive material to be exposed, the portion corresponding to horizontal scanning can be considered to have been replaced by light sources in arranged in an array. This can be incorporated in the category of scanning exposure. 
   The light sources preferably used in scanning exposure include a light emitting diode (LED), a gas laser, a semiconductor laser (LD), a combination between a LD or solid laser with LD used as an exciting light source and second harmonic wave change element (so-called SHG element), a combination between a VFPH element and chemical filter, a combination among a PLZT element, halogen lamp and optical filter, a combination between a tungsten light and band pass filter, a device which ensures that beam coming from the aforementioned CRT, liquid crystal display element and DMD element will become linear. Further, for the purpose of avoiding uneven exposure streaks caused by variations of devices or others in scanning exposure, it is possible to adopt a method wherein a plurality of small light sources are combined to ensure that the adverse effect of variations will be dispersed. In the processing of this digital exposure, the present invention is configured in such a way as to handle image processing when fulfilling a custom order of the customer  2 , e.g. superimposition of other images and letters. 
   The photosensitive material digitally exposed in the aforementioned manner is sent immediately to the development department  7 . Processing of digital exposure (Step S 3 ) is now complete. Upon completion of digital exposure, the job termination data is sent to the management server  30  via the exposure department terminal  60  (Step S 205 ). Upon receipt of the aforementioned job termination data, the management server  30  updates the data of customer database  332  (Step S 206 ). 
   The following describes processing of development by development department  7  in Step S 4  in  FIG. 7 : 
   In the photosensitive material development process, the photosensitive material is immersed in coloring developer for coloring development. The major coloring developer used in this case is aminophenol and p-phenylene diamide compound extensively used in various colored photographing process. Further, the coloring developer can be made by adding a known developer component compound to the aforementioned major coloring developer. Commonly used agents include an alkali agent having a pH buffering function, a development inhibitor such as chloride ion and benzo triazole, preservatives and a chelating agent. 
   The coloring development temperature is normally 15 degrees Celsius or more. Commonly used temperature is within the range from 20 to 50. The coloring development time is from 10 seconds to 4 minutes. 
   When running treatment is made with coloring developer being replenished continuously, the overflow of the coloring developer must be reduced to minimize pollution. For this purpose, the amount of coloring developer to be replenished is from 20 to 100 cc for each square meter of photosensitive material. 
   After having been subjected to coloring development, the photosensitive material is bleached and fused. Bleaching and fusing can be performed simultaneously. After fusing, the material is normally washed with water. It can be subjected to stabilization instead of water washing. A roller transport method wherein the photosensitive material is transported as it is sandwiched between rollers arranged in a treatment tank, or an endless belt method wherein the photosensitive material is fixed on a belt and is transported can be used as a development apparatus used for development of the photosensitive material according to the present invention. It is also possible to use a treatment tank formed in a slit which is filled with developer, and, at the same time, the photosensitive material is transported. 
   Upon completion of development (Step S 4 ) in the aforementioned manner, the development termination data is sent to the management server  30  (Step S 207 ) via the development department terminal  70  in response to the data input by the manager of the development department  7 . Having receiving this development termination data, the management server  30  updates the data of the customer database  332  (Step S 208 ). 
   Printing is completed by termination of the development. In Step S 5  of  FIG. 7 , the product is handed over to the customer  2 , and settlement of accounts takes place. 
   As described above, in the printing management system  1  of the present invention, reception of the customer  2  order, photosensitive material production control, digital exposure, development and other printing processes are all placed under the integrated management of the management server  30 , whereby smooth and efficient printing is ensured. 
   Since the management server  30  allows photosensitive material production volume and production time period to be determined in conformity to printing order, there is little need for worry about excessive storage or insufficient storage of photosensitive materials based on the prior art estimated production. Delivery from the manufacturing department  5  to the exposure department  6  is also placed under scheduled management with the result that secular deterioration of photosensitive materials can be avoided. Furthermore, the printing department (digital exposure department  6  and development department  7 ) need not take the trouble of placing an order for photosensitive materials or carrying out performance management. 
   If an agent sales method is used according to the prior art, the customers  2  are limited to those living close to an agent, with the result that the number of orders for printing is limited. Accordingly, installation of a photofinishing lab engaged in exposure and development in a photosensitive material manufacturing shop will give rise to imbalance between the photosensitive material production volume and the volume of printing order, and is economically not viable, according to this prior art. By contrast, orders received via the communications network  4  such as the Internet are not affected by geographical factors, and printing order can be accepted for 24 hours without sales personnel. This promises large orders, and therefore makes it economically viable to build a photosensitive material manufacturing shop (manufacturing department  5 ) and a photofinishing lab (exposure department  6  and development department  7 ) in one and the same site. The manufacturing shop and photofinishing lab constructed at one site simplify the light proof packages during transportation of photosensitive materials and storage facilities for minimizing performance deterioration. Thus, high-quality printing can be provided at low prices because both prevention of secular deterioration of photosensitive materials and cost reduction are ensured. 
   It should be noted, however, that the above embodiment is only an example, and may be modified as desired. For example, the photosensitive material production method is not limited to the ones explained in the present embodiment. Any method may be used if only a photosensitive material for printing can be manufactured. Furthermore, image data digital exposure and development are not restricted to the aforementioned methods; any method may be used if only printing can be completed. 
   The printing management system  1  according to the present invention may be configured in such a way that manufacturing, exposure and development are automatically carried out and controlled based on the instruction data sent to each terminal from a management server  30 , wherein a manufacturing department terminal  50  is connected with a photosensitive material manufacturing apparatus, an exposure department terminal  80  is connected with a digital exposure apparatus, and a development department terminal  70  s connected with a development apparatus. 
   Further, a management server  30 , manufacturing department terminal  50 , exposure department terminal  60  and development department terminal  70  may be connected with one another via the LAN 8  in such a way as to allow exchange of data among them. For example, delivery information may be exchanged between a manufacturing department terminal and exposure department terminal  60 . Further, connection may be made via the WAN and leased line or the like in addition to LAN 8 . 
   According to the invention of embodiment (1), production control information for the management of photosensitive material production volume and production time period is created by the production control information creating means based on the order data received from the customer terminal by receiving means, and this production control information is sent to the manufacturing department terminal by the production control information transmission means. This ensures production to be carried out in conformity to the order received from customers, thereby preventing excessive storage or insufficient storage of photosensitive materials. It also allows a production schedule to be formulated in conformity to possible deterioration of photosensitive materials. 
   Further, order data from customers is sent to the printing department terminal by the order data transmission means, facilitating processing of printing order. 
   Thus, this embodiment ensures efficient production while minimizing the secular change of photosensitive materials, and provides high-quality printing at low prices at the same time. 
   According to the invention of embodiment (2), the same effect as that of embodiment (1) can be obtained. Not only that, printing management information for scheduled management of printing is created by the printing management information creating means based on the order data, and this printing management information is sent to the printing department terminal by the printing management information transmission means. This enables effective printing in conformity to the amount of order accepted. 
   According to the invention of embodiment (3), the same effect as that of embodiment (1) or (2) can be obtained. Not only that, the aforementioned production control information provides production control information for adjusting production costs and production time period in such a way as to ensure the optimum inventory of the aforementioned photosensitive materials. This makes it possible to achieve the effective production because management is carried out in such a way that the secular deterioration of photosensitive materials can be minimized while the possibility of insufficient storage is eliminated. 
   According to the invention of embodiment (4), the same effect as that of embodiment (3) can be obtained. Not only that, the optimum inventory volume setting means allows the optimum inventory volume to be set in such a way that the photosensitive materials can be used up within a predetermined period of use, based on the aforementioned order data. This permits photosensitive materials to be consumed before the time of performance deterioration, and eliminates the need of excessive management of photosensitive materials. 
   According to the invention of embodiment (5), the same effect as that of embodiment (4) can be obtained. Not only that, usable period setting means allows the period of using the photosensitive material to be set based on the input of temperature in the warehouse storing the aforementioned photosensitive materials. This makes it possible to adjust the period of use in conformity to the storage environment. 
   The invention of embodiment (6) allows printing order, photosensitive material production control and printing management data to be exchanged via a communications line. This enables integrated management of all the processing related to printing, thereby allowing production of photosensitive materials in conformity to the amount of order accepted. 
   Thus, this embodiment ensures efficient production while minimizing performance deterioration of photosensitive materials, and provides high-quality printing at low prices at the same time. 
   According to the invention of embodiment (7), the same effect as that of embodiment (6) can be obtained. Not only that, printing is placed under scheduled management based on printing management information, whereby efficient printing is ensured. 
   According to the invention of embodiment (8), printing order, photosensitive material production control and printing management are performed in an integrated manner whereby photosensitive materials are produced in conformity to the amount of order accepted. This permits production adjustment to be made in conformity to the photosensitive material storage and secular performance deterioration in the manufacturing department. Further, use of a management server permits a great many orders to be received. Photosensitive materials produced in conformity to the received orders are used for printing in the printing department, and the photosensitive material manufacturing department and printing department can be installed close to each other, thereby cutting down transportation costs and reducing the amount of lightproof package. 
   According to the invention of embodiment (9), the same effect as that of embodiment (8) can be obtained. Not only that, the printing department allows printing to be performed based on printing management information, whereby more effective printing is ensured.
