Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology of a remote proof for performing color proofing at a remote place using a communication network (whether wired or wireless), and more particularly, to a technique for transmitting the color proof through a communication network. The proof image data is output as an image using an image display device such as a CRT or an LCD, or a proof print is output using a device such as a printer or a proofer, and then the image or the proof print (proof) is output. The present invention relates to a data transfer system and a data transfer method that are effective in efficiently and promptly transmitting the contents of a correction instruction based on a calibration result when the calibration is performed.

[0002]

2. Description of the Related Art For example, there is a distance between a plate making place for producing a printing plate and a person who performs proofreading, or there is an environment that may hinder the movement between them. If the situation is such that it is not possible to easily go back and forth (such a situation is collectively referred to as “at a remote location” in this specification), the proofreader sends a proofreader via a communication network. There is a remote proof technology that can transmit proofing image data and perform proofreading at a remote location. The proofreader receives the proofreading image data transmitted from the plate making shop, and outputs a printout using, for example, a printer using the image data, or
Calibration is performed after an image is output by the image display device. At present, generally, when using a remote proof system, a method in which a proofreader transmits a correction instruction to a plate-making shop by a proofreader who has written the correction instruction is transported to the plate-making shop. . When performing calibration,
There is also software that creates a data in which a correction instruction is written by a proofreader directly writing a correction instruction to image data.

However, there is a problem that it takes too much time to transmit the contents of the correction instruction from the proofreader to the person at the plate making shop when the manuscript on which the correction instruction is written is transported to the plate making shop.

When a proofreader uses software for creating data in which a correction instruction is written by directly writing the correction instruction to image data, depending on the image data to which the correction instruction is written, the proofreader writes the correction instruction to the network during transfer. There is a case where something is so large that a load is applied. As described above, various problems occur when transmitting the contents of the image correction instruction from the proofreader to the plate making shop.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and information to be transmitted, such as an output image or a content of a correction instruction for a proof print, is electronically transmitted. By constructing a remote proof system that has the function of transferring data from the proofreader to the plate-making shop via a network after converting it into data (eg, digital data), the proofreader can communicate with the partner represented by the plate-making shop. It is an object of the present invention to reduce the time required for transmitting a correction instruction when the user is in a remote place, and to reduce waste of communication concerning the correction instruction.

Also, there is an image output based on the image data for proofing or proof printing, but if the performance of the image display device or the image display technology is excellent, it is displayed on the screen even if it does not dare to output it to the printed matter. So efficiency is good. However, for example, when the user is particular about the proof print, which is an actual printed matter, or when only the print output device can be used, the proof print is proofread.
