Abstract
The invention relates to a method for carrying out color automatic correction on a file to be printed. In order to ensure that a printer of a plate-making factory more simply and effectively simulates the color of a printer, corresponding to the file to be printed of a client machine so as to lighten the workload of color correction, the invention provides a method for carrying out color automatic correction on the file to be printed. The method is characterized by comprising the following steps of: (1) before processing the file to be printed of the client machine, obtaining the color characteristics of the client machine and the printer; obtaining a color space converting relationship from the client machine to the printer according to the two color characteristics; and (2) then when a plate needs to be made according to the file to be printed of the client machine, simulating the printer effect by utilizing the obtained color space converting relationship to generate the file to be plate-made of the plate-making factory, and then transferring to the plate-making printer for printing simulation.
Description
Technical field
The application relate to treat the seal file carry out the method for color from dynamic(al) correction.
Background technology
The file that this paper is alleged is meant the e-file that is stored in the computer-readable medium.
Different color processing apparatus, its chromatic characteristic also are different.For example, to same file to be printed, go out part in kind (for example paper, offset plate etc. with client's printer prints, down together), print out part in kind with the printer/printing machine of plate-making factory again, though two parts in kind are derived from same file to be printed, because employed equipment difference, its heterochromia is quite obvious, can not satisfy ctp request.
As plate-making factory, its receiving of task is normally as Fig. 1, and client (for example printing house) provides and prints part a in kind, requires the color behind the Plate making printing identical with give printing part a in kind.Though plate-making factory can obtain and print the corresponding file A that waits to make a plate of part in kind (for example being stored in the computer-readable recording medium with the cmyk form) from the customers' place and make a plate, but because the chromatic characteristic of the printing machine of the printing house of being simulated and client's color processing apparatus (calling client computer in the following text) is different, so the color of the printing of the simulate press machine that obtains like this part a ' in kind and client print part a in kind bigger difference is arranged, need be through repeatedly colour correction, approach the color that the client prints part a in kind gradually, finally obtain printing the printing part in kind of the consistent simulate press machine of part a color in kind with the client.If before colour correction, can once obtain printing the more approaching plate-making printing e-file of color of part a in kind, then can alleviate the work load of colour correction with the client.
Summary of the invention
The problem that the application will solve is how to allow the printer of plate-making factory simpler, simulate more efficiently and print the color of waiting to print the corresponding printing machine of file with client computer, to alleviate the work load of colour correction.
The thinking that solves this technical problem is: as long as obtained the color space transformational relation from the client computer to the printing machine, later each plate-making just can be as Fig. 3, earlier obtain Ao by A, transfer to plate-making factory printer again and simulate printing, the color of resulting part in kind is identical with a just under perfect condition so.In order to obtain this color space transformational relation such as Fig. 2, utilize GB color table file T: client computer is printed GB color table file T and is obtained color table part t in kind, analyzes the chromatic characteristic p (being presented as chromatic characteristic profile file) that this color table part t in kind can obtain client computer with spectrophotometer then; Printing machine is printed GB color table file T and is obtained color table part t ' in kind (t ' color and t variant), analyzes the chromatic characteristic p ' that this color table material object part t ' can obtain printing machine with spectrophotometer then; Can obtain color space transformational relation from the client computer to the printing machine according to chromatic characteristic p and p '.
Provide in view of the above treat the seal file carry out the method for color from dynamic(al) correction, it is characterized in that,
(1) before processing client is waited to print file
Obtain the chromatic characteristic of client computer and the chromatic characteristic of printing machine;
Obtain color space transformational relation from the client computer to the printing machine according to above-mentioned two chromatic characteristics;
(2) then when need are made a plate according to client computer file to be printed
Utilize resulting color space transformational relation, simulate press machine effect, the file to be made a plate of generation plate-making factory is transferred to the plate-making printer and is printed simulation.
Said method is because obtained the color space transformational relation from the client computer to the printing machine before processing client waits to print file, so in the future when need are made a plate according to client computer file to be printed, utilize the color space transformational relation of gained to generate plate-making factory file to be made a plate, transfer to the simulation of plate-making factory printer and print desired printing effect, its color is identical with regard to the color of printing part in kind with the client under perfect condition.
Description of drawings
Fig. 1 is the color situation schematic diagram that different color equipment is printed identical file gained part in kind.
Fig. 2 derives to draw the process schematic diagram of color space transformational relation.
Fig. 3 utilizes the color space transformational relation to realize that different color equipment prints the schematic diagram of the part in kind of same color.
The specific embodiment
As Fig. 2, client computer is printed GB color table file T and is obtained color table part t in kind, analyzes the chromatic characteristic p (being presented as chromatic characteristic profile file) that this color table part t in kind can obtain client computer with spectrophotometer then; Printing machine is printed GB color table file T and is obtained color table part t ' in kind (t ' color and t variant), analyzes the chromatic characteristic p ' that this color table material object part t ' can obtain printing machine with spectrophotometer then; Can obtain color space transformational relation from the client computer to the printing machine according to chromatic characteristic p and p '.
Then in the time need making a plate according to client computer file to be printed, waiting to print file A with arbitrary client computer is example, as Fig. 3, utilize resulting color space transformational relation, simulate press machine effect, generate the file Ao that makes a plate that waits of plate-making factory, transfer to the plate-making printer and print simulation, then under perfect condition, can obtain color and print the identical simulate press product of part a color in kind with the client.Although still there is the error that is difficult to avoid in both colors in practice, the color of the simulate press product that this method obtains very near part sample a in kind, can be directly used in plate-making.
The method that this paper provides, all or part of step wherein can be finished by computer program instructions control computer system by setting up functional module construction.These computer program instructions are stored in the computer-readable recording medium.
Claims (1)
1. treat the seal file and carry out the method for color, it is characterized in that from dynamic(al) correction,
(1) before processing client is waited to print file
Obtain the chromatic characteristic of client computer and the chromatic characteristic of printing machine;
