Problems solved by technology

In this case, the image processing device disclosed in Patent Document 1 further implements color gamut matching based on the output property file for the object that has undergone the color gamut matching based on the input property file, so that the problem of poor color reproducibility occurs
[0007] The user can specify the output device in the input property file, but if the output device specified in the input property file is different from the actual output device specified in the output property file to output the data file of the print target, color reproducibility will also occur when printing is performed. falling problem

Embodiment Construction

[0031] Embodiments of the present invention are described below with reference to the drawings.

[0032] figure 1 is a schematic diagram of the printing control system 100 of the present invention. This print control system 100 includes a user PC 110, attribute evaluation means 120, attribute management means 130, device control means 140, and printing means 150a and 150b. These devices are connected to the network 160 . The network 160 is a network such as the Internet or a LAN.

[0033] The user PC 110 is a print processing device having a function of a print request unit, and requests to provide a data file to be printed according to a user instruction. A color conversion table (hereinafter referred to as a color reference attribute file) is embedded in the data file of the printing object, which is used to convert the object color contained in the data file into a color that can be displayed by the printing device of the output device. A color reference property file ...

Abstract

The present invention relates to a print control system for controlling print processing, and an object of the present invention is to provide a print control system and method capable of preventing color reproducibility degradation caused by attribute setting errors. The print control system of the present invention includes a user PC (110) that transmits data and attributes of a print object and requests printing as a print request unit, and an attribute evaluation device (120) that evaluates attributes and controls execution of print processing as a print control unit . Among them, the attribute evaluation device (120) notifies the user PC (110) that the attribute setting is incorrect when the attribute setting is incorrect, and the user PC (110) notifies the user PC (110) when receiving the notification that the attribute setting is incorrect. The user properties are not set correctly.

Description

technical field [0001] The present invention relates to a print control system for controlling print processing, in particular to a print control system and method for controlling print processing by evaluating attributes during printing. Background technique [0002] The previous color management technology is to use ICC property files (such as input property files and output property files, etc.) that describe the correspondence between device-dependent color spaces (such as RGB and CMYK, etc.) ), implement color matching between multiple image processing devices through a device-independent color space. [0003] Usually between the input device (scanner and digital camera, etc.) and the output device (printer, etc.), the color space that can be displayed is as follows: Figure 19 As shown, there are many differences. Therefore, when printing image data formed in colors that cannot be displayed by a printout device, it is necessary to perform color gamut matching to conver...
