Abstract

PURPOSE:To permit the centralized control of preset data on ink of a subsidiary ink supply amount setting processor by a master ink supply amount setting processor by a method in which modulating equipments and demodulating equipments are provided to each of the master and subsidiary (plural) ink supply amount setting processors. CONSTITUTION:It is inquired whether a preparation for receiving data is completed or not to a subsidiary processor 14 by a master processor 11. An answering on whether or not data from the master processor 11 can be received is made to the master processor 11 by the subsidiary processor 14. If the receiving of data from the master processor 11 by the subsidiary processor 14 is possible, an operating switch provided on the operating panel 22 of the master processor 11 is operated to send a transmission startup command to CPU31. As a result, data stored in the memory 33 are sent to the CPU411 of the subsidiary processor 14 through MODEM controller 34, MODEM16 and 17, and I/O port 421 by the CPU31. In the CPU411, the data sent from the master processor 11 are stored in the memory 431.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a master station ink supply amount setting processing device and a plurality of slave station ink supply setting processing devices each with a post-adjustment device,
The present invention relates to an ink supply amount setting processing device in which ink preset data of a slave station ink supply amount setting processing device can be centrally managed by a master station ink supply amount setting device.

Conventionally, an ink supply amount setting processing device uses data (hereinafter referred to as initial preset data) output from a curve area area meter that measures the area ratio of the ink-applied portion of printed matter, that is, the image area ratio of the printing plate. The initial preset data that is input is converted into a numerical value indicating the position of the doctor blade at each position using a predetermined function, and the position of the ink key that displaces the doctor grade based on the numerical value is required for each machine. Therefore, in order to process multiple printing presses, multiple ink supply and setting processing devices were required. For this reason, controlling the amount of ink supplied to the paddy count printing machine has the disadvantage of being extremely expensive. This invention was made in view of the above points, and its purpose is to A modem is provided in each of the station ink supply amount setting processing device and the plurality of slave station ink supply amount setting processing devices, and the ink reset and data of the slave station ink supply amount setting processing devices are centrally managed by the master station ink supply setting processing. An object of the present invention is to provide an ink supply amount setting processing device that can perform the following steps.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Next, the operation of the present invention configured as described above will be explained. Master station 1) and slave station 1 using Figures 1 and 2.
The flow of input/output signals between 4 and 15 will be explained. First, a case will be described in which data obtained by converting a picture area ratio into an adjustment position of an ink key in the master station 11 is transmitted to the slave station 14 or 15.

Oiler 1 is the operation channel 2 installed in the master station I.
2. Select the type of printing press to be glazed using the machine glaze selection switch on the top. Then, when the corresponding model is selected, the CPU J 1 specifies a function setting digital switch panel, for example, a digital switch panel 32, that is suitable for the selected model from among the plurality of conversion function setting digital switch groups 32. Digiswitch/4 channel 3
The set value of No. 2 is input to the CPU 31.

Next, the magnetic card 20 on which the picture area ratio is recorded for each ink supply amount of each ink key is inserted into the magnetic card reader 19. Thereby, data on the picture area ratio read from the magnetic card reader 19 is input to the CPU 31. This CPU 31 calculates the setting value of the ink key adjustment position required for each picture area ratio, and the calculation result is stored in the memory 33. Then, in order to transmit the data stored in the memory 33 to multiple slave stations 14 and 15 installed, an attempt is made to transmit the data using the operation switch provided on the operation panel 22 installed in the master station 1. -0 The operation will be explained when, for example, the slave station 14 is specified.

First, the master station 1 is ready to receive data from the slave station 14.

Send to Tsuno. This CPU 411 stores the data transmitted from the master station 11 in the memory 431.

Next, in the slave station 14, when a preset start command (not shown) is sent to the CPU 411, the CPU 411
31, each ink key motor 471 and ink source motor 48 are driven via a driver 491. As a result, ink resetting is performed. Here, a iiJ side view of the digital switch panel 321 is shown in FIG. Y, M, C, BL, S in Figure 3
l, 82 is yellow, red, eye, black, special feature 1. Indicates special feature 2, and the pattern area ratio is 10 cm, 20 cm, 40%, 60 cm, and 1
A conversion function for each υ color is formed by the set number corresponding to 00%. -For example, the yellow conversion function is set as shown in Figure 4.

Next, among the ink key potentiometers 441, 442 and ink source potentiometers 451, 452 attached to the printing press 12, 13, for example, ink key potentiometer 44 and ink source potentiometer 45 are selected.
The data from the magnetic card 2θ is used as repeat data.
.

The case where you want to record on 21 will be explained. Note that repeat data refers to recording the current operating state of the printing press at the position 7 of the ink key potentiometer in preparation for a later job.

First, the analog input power of the potentiometers 441 and 451 is converted into a digital signal by the ADD converter 461 provided in the slave station 14, and is stored in the memory 43 as data for serial repeat by the CPU 41J. Next, the slave station 14 makes an inquiry to the master station 11 via MODEM 17.16 as to whether the data stored in the memory 431 can be transmitted.

In response, the master station 11 receives data from the slave station 14.
tJ ”Reply to the slave station 14 whether it is possible or not.

Then, the slave station 14td receives the reply from the master station 11, and if the master station J is capable of receiving data, sends a data transmission start command from the slave station 14.The CPU 411 transmits the data stored in the memory 431. I10 boat 421MODEM
J 7 , 16 , is transmitted to the CPU 31 of the master station 1 via the MODEM controller 34 . And the CPU
The repeat data sent to the slave station 14 at step 37 is converted into 9 elements by the conversion function set in the digital switch panel 321 corresponding to the slave station 14 in the digital switch panel group 32. The picture side 8 of is returned to the original value and stored in the memory 33 (inverse conversion). After the repeat data is stored in the memory 33, the operation switch on the operation panel 22 is operated to enter the magnetic card writing state. Next, the magnetic card 2 is inserted into the magnetic card reader 19, and the repeat data stored in the memory 33 is recorded on the magnetic card 2.

In addition, when using a printing machine manufactured by another company, the M
The present invention can be applied by equipping the MODEM J 7 to transmit data from the MODEM J 6 of the master station 11.

As described in detail above, the present invention provides an ink preset system that includes one master station ink supply setting processing device and a plurality of slave station ink supply setting processing devices corresponding to printing machine level. Since t nu is made to occur, the following further effect occurs.

(Ink reset for 1-number printing machines can be centrally managed from one master station.
