Embodiment Construction

[0031]

[0032]

[0033] Fig. 1 schematically shows the structure of a printing system 10 including a print data generating device 1 according to a first preferred embodiment of the present invention. The printing system 10 is a system that generates print layout data (hereinafter simply referred to as "print data") and then outputs printed matter based on the print data, in which a document is described in a predetermined page description language (PDL) such as a portable document format (PDF). Print data. The printing system 10 mainly includes a printer 2 and a recovery processor 3 in addition to the print data generation device 1 . The print data generating device 1 is connected to a printer 2 and a recovery processor 3 via a network N.

Abstract

The invention provides a printing system which is used for producing printing data and printing job data in order to be capable of being recovered from printed matters. According to predictive encoding technique, the invention symbolizes PDL- transformed typesetting data which is obtained through executing PDL transformation of predictive typesetting data and image data with symbol produces the PDL transformation, wherein the generation data is combined with the PDL- transformed typesetting data and then is provided to printer as printing data which is printed to produce the printed matters PM, wherein symbol SB is appended on existence image which is hoped to be indicated when typesetting time and is capable of being read and deciphered utilizing predictive recovery processor which is provided with decryption device with corresponding to the encoding technique, thereby faithfully recovers the PDL- transformed typesetting data, as long as reserving files under the formation of the printed matters, the invention is capable of easily executing repetitive-use of the typesetting data and has no use for saving electric data.

Description

technical field [0001] The present invention relates to the generation of print data, and in particular to the generation of potentially reusable data. Background technique [0002] Preserving files (not limited to text, but also plain images) that have been used for print production in the state of electronic data provides convenience in that they can be reused later. This storage method can be widely implemented in the form of storage on portable storage media or computer hard disks or dedicated database servers, for example. [0003] On the other hand, when documents are stored for a long period of time, there are still many cases where documents are stored in the state of prints printed on paper media. For repeated use, electronic data representing the document is also generally generated based on the content of the document (consisting of text, images, etc.) saved as a printed matter. A typical method of reading documents is to use a scanner to acquire image data, and...
