Description

Cloud-based smart printing platform operating device through environmental analysis}

The present invention relates to a cloud-based smart printing platform operating device through environmental analysis, and more particularly, optimizes printing quality through analysis of printing environment information such as temperature, humidity, dust, etc. It efficiently distributes and schedules printing jobs, standardizes the entire printing process, and enables collective management from the ordering stage to process monitoring, feedback, final production and delivery in connection with online printing shopping malls. It is about a cloud-based smart printing platform operating device through environmental analysis that can be flexibly applied to the size of the demander or the printing equipment owned by modularizing it by each).

Conventional printing factories and shopping mall operators provide print samples with the best quality in response to consumers' printing requests, and produce prints with quality corresponding to the sample when the consumer confirms the print sample and signs a contract.

However, in this conventional printing method, samples of printed matter provided to consumers are made under optimal printing conditions, but in the actual printing process, there is a difference in print quality depending on the printing environment information of the printing factory, that is, order status, temperature, humidity, dust, etc. This may occur, and the operator cannot immediately check and correct this difference, so that the print quality is worse than the sample print, causing consumers to be dissatisfied or having to re-produce the print.

In particular, this problem is in most cases when there is a printing request through a shopping mall, the operator of the shopping mall resides in the actual printing factory and cannot immediately grasp the environment such as the order status, temperature, and humidity of the printed matter. Since it is not possible to provide a solution, such as newly setting the parameters of the printing device according to the printing environment or distributing print orders, problems such as delayed delivery period or quality deterioration for consumer printing requests occur. It became.

Moreover, even if a worker in a printing factory continuously measures temperature, humidity, dust, etc., and adjusts the printing environment accordingly, it is very cumbersome and difficult to adjust them one by one. There was a problem that the print quality could not be maintained constant because it could not be solved.

In addition, printed materials must go through post-processing processes such as coating, binding, and cutting, and these post-processing must vary depending on the type of printed material. There was a problem with the lengthy period.

On the other hand, the recent demand for printed matter is changing to a small quantity of various types, and in the case of mart leaflets, for example, it is changing from a batch printing method for one year to a small quantity printing method per week.

In order to process a small amount of printed matter like this, in order to proceed with another print job after completing one print job, the types and conditions of the printing process and post-processing process must be set again. There was a problem that the defective rate of printed materials increased and the working speed of printed materials was slowed down.

In addition, social demand for eco-friendliness of printing technology is also increasing due to environmental regulations on the printing industry and increased consumer interest in the environment. It is necessary to respond to the demand for eco-friendliness by minimizing waste such as water and damp water.

However, in the case of the offset printing press, the color matching process is complicated and it is greatly affected by environmental variables (temperature/humidity), so it is difficult to maintain a constant quality when printing in small quantities and various types. Although digital printers and offset printers that are less affected are used in combination, there was a problem that the operator had to manually select one by one because a system that could automatically select and control them was not equipped.

As a result, some printing process automation is currently in progress, but it is generally built in the form of SI (System Integration), for example, online shopping mall construction (order/delivery/payment), work instruction file (JDF) management, and automatic color matching system However, since automation is progressing separately for each device or process, it is required to build a system that integrates the entire printing process.

In addition, since printing goes through a complicated process in which various types of devices, processes, and external work coexist, data must be exchanged in each process to be standardized.

On the other hand, since printing orders such as business cards, stickers, magnetic products, envelopes, and employee ID cards require a variety of papers and post-processing to be processed in a complex manner, a process monitoring function that enables real-time feedback from the orderer is required.

2 to 7 are diagrams showing an embodiment of a cloud-based smart printing platform operating device through environment analysis according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Cloud-based smart printing platform operating device through environment analysis according to the present invention, as shown in Figure 1, one or more pre-processing devices 10 for converting the edited file into a file format suitable for the printing device; one or more printing devices 20 outputting the file transmitted from the pre-processing device; A post-processing device 30 for performing post-processing including coating, cutting, and binding on the printed matter output from the printing device; an environmental information detection sensor 40 for measuring printing environment information including temperature, humidity, and dust around the printing device and the post-processing device; According to the input operation control command, an operation control signal is output to one or more connected devices among the pre-processing device 10, the printing device 20, and the post-processing device 30, and the pre-processing device 10 and the printing device 20 and a factory server 50 that transmits process data transmitted from the post-processing device 30 and environmental information data of the environmental information detection sensor 40; And process data and environmental information data transmitted from the factory server 50 are recorded, and based on this, a control command including the operation parameters of the optimal printing device and post-processing device is calculated and transmitted to the factory server 50. A smart factory server 60 is configured to include;

On the other hand, the cloud-based smart printing platform operating device is further provided with a manager terminal connected to the cloud-based smart factory server 60 and the factory server 50 to remotely check and control the entire process of printing.

In the above, the pre-processing unit 10 is a device that converts files of various formats that customers work and upload into standardized files. More specifically, QuarkExpress converts Mac to PostScript, Adobe files, MS, and Hancom documents. After converting to a PDF file on an IBM PC, RIP (Raster Image Processing) process is performed to convert the converted file into a state that can be output on a printing device.

Among them, the RIP (Raster Image Processing) process translates the digital data (text, photographic image, illustration, etc.) information created on the screen by computer editing tools into PDF (or Postscript) and converts each printable color component into four (CMYK) ), it is divided into black and white halftone dots (Rraster) information, and the process of recording.

In addition, the printing device 20 includes a CTP (Computer to Plate) printing device, an offset printing device, and the like.

The CTP (Computer to Plate) printing device means that if the existing printing process was to create a printing plate through a film (Computer to Film), CTP means a system that creates a printing plate directly from a computer without a film production process (Computer to Plate). It has the feature of reducing the dot loss from the past film work because the data that has been worked is irradiated and developed with laser on the printing plate immediately after the pre-press process.

In addition, the offset printing device is a printing method of printing on paper using a printing plate and a rubber roller, and uses a method in which ink painted on a metal printing plate is applied to the paper through a rubber blanket.

This offset printing device distributes the paper pallet to the paper feed section, accurately positions the paper according to the position (pin) and height, attaches the printing plate in color order, removes the previous image from the blanket and cleans it, Check that the color and ink stain prevention powder are working properly, and take out the printed material from the delivery unit and make fine adjustments to fit the sample. Considering the different ink concentrations by manufacturer, the amount of ink, the number of times of stirring, room temperature, amount of wet water, and operating speed and adjust the amount of ink supplied (adding auxiliary agents such as drying agents and drying inhibitors according to the printing situation) while periodically comparing with samples.

And the post-processing device 30 refers to a device that performs cutting, binding, shape picking, coating, etc. to suit the purpose after printing.

Examine environmental factors that determine print quality.

First of all, the printing quality changes depending on the temperature and humidity environment. When the temperature is low, the supply and application of the ink become inappropriate due to hardening of the ink, and the shrinkage of the printing paper occurs. When the temperature is high, the ink becomes thin and the color spreads. phenomena such as

Other temperature changes may cause failure of the main motor, compressor, damp water cooling device, pneumatic device, static eliminator, dryer cooling device, powder spraying device, etc.

In addition, when the humidity is low, problems occur in smooth supply and uniform loading of printing paper due to static electricity, and in the case of thin printing paper, paper is wrinkled during feeding, and when the humidity of the paper storage area is low, The paper loses moisture, causing the edges to curl, and in this case, the paper is fed at an angle, causing paper jams.

When the humidity is high, powder spraying is not uniform, and due to the moisture content of the printing paper, proper ink transfer is not performed, resulting in deterioration in quality. There is a problem that paper is not fed to the machine or paper is slanted.

Since the print quality also differs depending on the quality of the paper, the most suitable paper for each printing purpose and use must be selected for all printed materials.

In other words, paper must be selected according to criteria such as basis weight, thickness, color, and smoothness (roughness and smoothness) of the paper. Eye fatigue can be reduced only by choosing.

In addition, the printing quality varies depending on the dust/ventilation of the workplace, and the printing workplace is exposed to an environment in which dust from the dust of the printing paper and the powder used for drying the printed matter are scattered. (紙粉) and powder easily wear out the parts of the printing machine and reduce the heating function in the environment of the electronic equipment.

On the other hand, in offset printing, the printing quality is greatly influenced by the wet water. The materials constituting the wet water are ① water, ② Acid or base (weak acid such as phosphoric acid, chromic acid, tannic acid, etc., and ammonium phosphate, ammonium nitrate, etc.), ③ Gum (hydrophilic separator substances such as gum arabic and CMC), ④ Corrosion inhibitors (magnesium nitrate, etc.), ⑤ Buffer, ⑥ Wetting Agent (IPA), ⑦ Drying stimulator (cobalt chloride), ⑧ Fungicide, ⑨ Antifoaming Agent, etc. The mixing ratio with water greatly influences the printing quality.

This wet water prevents ink from being applied to the non-drawing part of the printing plate, prevents the undetectable agent from coming off from the plate, stabilizes the drawing line part, suppresses heat generation of the ink roller, lowers the cohesive force (tech value) of the ink, Prevents roller damage and extends Molleton life.

In addition, even the same color may look different depending on the color temperature (K) of the lighting, and the color may be distorted due to the characteristic cool white color and high color temperature of the fluorescent lamp commonly used in the working environment.

Therefore, when the factory server receives these printing environment information data and process information data and transmits them to the cloud-based smart factory server, after analyzing them, parameters are set so that the printing device and post-processing device can produce the highest quality, It is delivered to the printing device and the post-processing device through the server, and the analysis result is transmitted to the manager terminal used by the manager of these devices. If necessary, a warning message is delivered so that the printing environment can be constantly managed and the print quality can be maintained. let it be

In the above configuration, the environmental information detection sensor is composed of a small embedded device (based on Non-OS) and based on BLE (Bluetooth Low Energy), and is equipped with an MCU and wireless communication integrated solution (CC2650) to communicate wirelessly with the factory server. do.

And, as shown in FIG. 2, the factory server is wirelessly connected to the environmental information detection sensor and connected to the cloud-based smart factory server through Ethernet, so that the user can input various information to control the operation of the printing device. It is equipped with a touch pad-based input means to enable monitoring while doing so.

As an example of the touchpad, as shown in FIG. 3, JDF files for jobs currently in progress and pending jobs are read and displayed in a list, printing environment data such as temperature, humidity, and dust are output, and information displayed in the list is displayed. Suggests a menu (detail view, etc.) to display detailed information about

In addition, as shown in FIG. 4, printing errors are prevented by displaying an image currently being worked on so that the operator can check it.

The cloud-based smart factory server collects and analyzes environmental information data and process data transmitted from the factory server in real time. The generated data is stored in the cloud and an optimal print quality environment is established through data mining.

That is, a sequential pattern technique is applied in which printing environment information data and process data are configured as input variables, and the amount of printing per hour and quality defect rate are configured as output variables, and only variables with a high significance level are used through a t-test. to create rules and models.

As shown in FIG. 5, the types of environmental information data and process data include all collectable data such as date, ink type, temperature, humidity, and water, and record data in the form of a work log during each print job, These data, that is, input variables that affect print quality, are analyzed using a t-test and GSP (Generalized Sequencial Pattern) algorithm, and the main factors appearing through the above analysis are rules using the GSP algorithm as shown in FIG. create

The cloud-based smart server that performs these tasks develops Message Queue, Streaming Framework, Storage, and IoT Analytics that can read and store data based on Module Manager that can manage modules, and Web UI to view stored information on the Web. make up

At this time, the message queue is necessary to more effectively route messages in a complex industrial IoT environment, process a large amount of streaming data, and process a large amount of data of a sensor network without a bottleneck. Do.

In addition, from the collected data, if there is a problem or failure in the printing device, it is notified to the manager terminal so that the operator can check it in real time.

In addition, the cloud-based smart factory server learns past data as well as preset rules in conjunction with machine learning technology to automatically identify anomalies.

And the cloud-based smart printing platform operating device is further provided with a shopping mall server that operates an online shopping mall for printing orders, and when a consumer requests a printing order through the online shopping mall, the corresponding print request information is transmitted through the shopping mall server to the cloud-based smart printing platform. It is transmitted to the factory server and stored in the database, and the order information is delivered to the manager terminal that manages the pre-treatment device, printing device, and post-processing device, so that the control command is transmitted to the factory server according to the manager's review result so that the factory operation can be directed. , It monitors where the order file is located in the pre-processing, printing, and post-processing processes, and when abnormal symptoms are found according to the environmental information of the printing plant, it notifies the manager terminal and notifies the progress result of the print order to the consumer terminal. Share relevant data.

In addition, the cloud-based smart factory server, as shown in FIG. 7, a pre-processing module for driving a pre-processing device, a printing module for controlling a printing device, and a post-processing module for controlling a post-processing device. By modularizing each function, such as a shopping mall module for linking with a shopping mall and an outsourcing module for outsourcing, not only the printing factory, but also separate advertising agencies and post-processing companies are connected to the cloud-based smart factory server through each terminal to link work with each other allow it to proceed.

In the above, the preprocessing module consists of ① CEPS conversion, ② standardization, ③ copy dot, ④ PDF preflight, ⑤ spot color processing, ⑥ overprint conversion, ⑦ color matching, ⑧ trap, ⑨ small image, and ⑩ file transmission.

The setting of each process is to input the setting value for each process on the setting screen of the process after creating the process, and the process that has been set up has one input folder and one output folder. It will carry out the specified process.

Depending on the type of production line, the printing module delivers the preprocessed output file to the printing device along with the JDF (Job Definition Format) file distributed by CIP4 to the printing device, which consists of offset printing, digital printing, and plotter, depending on the type of production line. Start test printing and actual printing using JDF and PDF files.

At this time, in case of offset printing, color defects are often caused by inserting the plates upside down or incorrectly fitting them to CMYK, so a process of creating a thumbnail image before printing and letting workers know is absolutely necessary.

The post-processing module produces modules for each process, such as cutting, wireless binding, and saddle stitch binding, and each module controls the process based on the JDF file.

The outsourcing module provides a smart factory-online shopping mall-outsourcing space linkage module so that order details can be delivered accurately and quickly. After placing an order according to the order, an environment is established, and the process can be instructed based on the file.

On the other hand, the cloud-based smart factory server and the factory server constituting the cloud-based smart printing platform operating device are connected to the shopping mall server.

Since the cloud-based smart factory server configured as described above collects and judges various data, it is possible to standardize the entire printing process through efficient distribution and scheduling of printing jobs, and to print orders requested by consumers through online shopping malls, the order information is processed The result can be grasped and notified to the consumer terminal.
