Embodiment Construction

[0031]

[0032]

[0033] Fig. 1 schematically shows the structure of a printing system 10 including a print data generating apparatus 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 present invention provides a printing system for generating print data and print job data to enable recovery from printed matter. PDL-converted composition data obtainable by performing PDL conversion of predetermined composition data is symbolized with a predetermined encoding technique, and image data of the obtained symbol is subjected to PDL conversion. The generated data is combined with PDL-converted layout data, and then supplied to the printer as print data. Printing of the print data generates a printed matter PM in which the symbol SB is added to a solid image, that is, an image of what is desired to be represented at the time of typesetting. With a predetermined restoration processor having decoding means corresponding to the encoding technique, the symbols SB can be read and decoded, thereby faithfully restoring the PDL-converted compositional data. As long as the document is kept in the form of printed matter, the reuse of typesetting data can be easily performed without saving electronic 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...
