  The data output system 1 includes a data output device 10, and the data output device 10 includes a PDL data synthesis unit 11 and a PDL data output unit 12.

  The PDL data synthesis unit 11 synthesizes PDL data representing a print target image in a public page description language and PDL data representing a copy-forgery-inhibited pattern image added to the print target image in a non-public page description language. .

  Specifically, the print target image is an image of print target data requested to be printed by the user. Here, the print target data may be data that can be printed by the printing apparatus. For example, the data to be printed is data of various application software such as document creation software and spreadsheet software, and document data such as various image data.

  A copy-forgery-inhibited pattern image is an image embedded in a print medium on which a print target image is printed, and is also referred to as a watermark. The copy-forgery-inhibited pattern image is embedded in the entire print medium, for example. In one aspect, the copy-forgery-inhibited pattern image is an image including information related to security. For example, an image for ensuring the security of an image to be printed, an image for suppressing unauthorized copying of printed matter, and a copy of printed matter are restrained. Images, and images for tracking information sources and outflow routes. In a specific aspect, the copy-forgery-inhibited pattern image is an image in which predetermined information emerges when copied by a copying machine. For example, when a copy-forgery-inhibited pattern image has a background portion that is not reproduced by copying by a copying machine and a latent image portion that is reproduced by copying by a copying machine, and a printing medium in which the copy-forgery-inhibited pattern image is embedded is copied by a copying machine, The pattern of the latent image appears on the copy. Here, as information relating to security included in the copy-forgery-inhibited pattern image, for example, information for specifying the creator of the print target data (for example, the name of the document creator), information for specifying the person who performed printing (for example, For example, the name of the print requester), the name of the data to be printed (for example, the document name), the date and time when printing was performed, the information for identifying the client device that transmitted the print request (for example, the IP address), and the printing device that performs printing Information (for example, an IP address), characters such as “copy prohibited”, a mark such as a municipality, and information (for example, a serial number) for specifying a printed matter.

  Examples of the published page description language include general-purpose page description languages such as PCL (Printer Control Language) and PostScript.

  An example of the private page description language is a page description language unique to the manufacturer of the printing apparatus 2.

  In the present embodiment, the PDL data representing the print target image in the published page description language and the PDL data representing the copy-forgery-inhibited pattern image added to the print target image in the non-public page description language are combined. Output. For this reason, according to the present embodiment, it is possible to prevent the copy-forgery-inhibited pattern image from being easily counterfeited while responding to a request to use a public page description language for the print target image.

  For example, since the copy-forgery-inhibited pattern image is expressed in a private page description language, it is not easy to decode or forge the PDL data of the copy-forgery-inhibited pattern image compared to the case in which the copy-forgery-inhibited pattern image is expressed in a public page description language. In particular, forgery of a copy-forgery-inhibited pattern image is difficult in a mode in which different data for each document or page (for example, data in which a date or serial number is encoded) is inserted into the copy-forgery-inhibited pattern image.

  Further, for example, since the print target image is expressed using a public page description language (for example, a general-purpose page description language), it is sufficient that a non-public page description language can handle a tint block image. For this reason, it is possible to easily define or create a non-public page description language as compared to a case where both the print target image and the copy-forgery-inhibited pattern image are handled in a non-public page description language.

  Further, for example, since the print target image is expressed using a published page description language, the user can use a printer driver (for example, a general-purpose printer driver) of the published page description language.

  In addition, for example, the data output device and the data processing device need only handle one type of page description language for the copy-forgery-inhibited pattern image, so that the configuration is simplified compared to the case where a plurality of types of page description languages are handled.

  In addition, this invention is not limited to the said embodiment, It can change variously within the range which does not deviate from the summary of this invention.
