Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a layout scanner system used for plate making of a manuscript such as a color photograph, for example, and particularly to a change in color tone for image information registered in a database. The present invention relates to a scanner system in which processing is performed without updating image information each time, and work efficiency and quality can be significantly improved.

[Prior Art] At present, in the field of plate making, a layout scanner system has been developed and put into practical use when making a plate of a document such as a color photograph. This layout scanner system has an editing function capable of outputting one or more images in a desired layout on one film.

And this kind of layout scanner system,
It is sold by many manufacturers and is extremely revolutionary as a plate making system. Its general use is, for example, a special process for erasing acne, wrinkles, and the like of a person image, and a method of performing plate making (plate collection). In addition, printing of color photos is generally handled as a temporary process, but catalogs, pamphlets, leaflets, etc. are used for image processing such as enlarging, reducing, rotating, etc. In many cases, trimming is changed and reused or reused. Such work is generally the work of collecting the former,
The latter is often referred to as a plate making operation using a database.

[Problems to be Solved by the Invention] By the way, color photographs and the like that are frequently used (diverted and reused) can be stored in a recording medium such as a magnetic tape or a magnetic disk and reused. Then, in the plate making operation using such a database, the construction of the database is usually performed with the consent of the customer regarding the quality (color tone and the like) of the image, but the color tone is often changed.

That is, this factor is often on the customer side, but it may also be due to variations in quality of quality checking means such as proof printing when checking color tone. In response to such a color tone change request, the currently registered image information is updated each time.

However, in such a method, the load of image production that occurs when updating the image information is very large, and a document is often required, so that this arrangement also requires a great deal of trouble.

As described above, in the conventional layout scanner system, the image information must be updated each time the color tone is changed for the image information registered in the database, and as a result, the work efficiency is significantly reduced. However, there is a problem in improving the quality of plate making, which is an important part of the printed matter making process, and in shortening the delivery time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and a color tone changing process for image information registered in a database can be performed without updating image information each time.
