Description:
BACKGROUND 
       [0001]    Disclosed herein is a system and method for marking intentionally blank pages as such in a document. 
         [0002]    Embodiments of the disclosure are well suited for marking intentionally blank pages in documents that are printed or in documents that are copied. 
       SUMMARY 
       [0003]    The concept of detecting blank pages during a copy job or a print job is very useful, especially during the printing or copying of legal or regulatory documents. An author of the document may want to indicate to the reader that the blank page is deliberately blank and that it is not an omission. However, in some systems when a blank page is detected the blank page is not printed and is skipped completely. This removes the separation in the final print product that was originally desired to be indicated by the presence of the blank page. This also removes the separation that is often necessary to start a new section of the document on the desired page for appearance purposes. 
         [0004]    In some systems, a user needs to indicate manually and separately each blank page on which the user desires to include a blank page identifier. Identifiers can be text such as, for example, “This page is intentionally blank” or can be a watermark or other printed identifier. This process can be tedious and can easily lead to errors due to the user having to manually indicate which pages require the identifier. 
         [0005]    In embodiments of the disclosure, when a user submits a copy or print job including one or more blank pages in the original, some systems can detect the blank pages and automatically mark those pages as intentionally left blank using annotation or watermark options. 
         [0006]    In embodiments of the disclosure, the blank pages can be automatically detected using an algorithm or pattern and the system can provide the user an option to identify the blank pages with a printed identifier. 
         [0007]    By configuring annotation or watermark settings, when such blank pages get detected during copy or print jobs, the system allows marking these pages with printing an annotation text such as, for example, “This page is intentionally left blank”, or another identifier. 
         [0008]    An embodiment of the disclosure may include a system for marking intentionally blank pages in a document. The system includes a processor that processes a document in an electronic form; a blank page detection routine that is run by the processor, the blank page detection routine being configured to detect a blank plank page in the document; and a blank page indicating routine that is run by the processor, the blank page indicating routine being configured to indicate with an indication that the blank page is an intentionally blank page. The indication is configured to be read by a marking device such that the marking device marks the blank page as intentionally blank. 
         [0009]    In some embodiments of the disclosure the blank page indicating routine is part of a driver of the marking device, the driver being a set of configuration commands that are associated with the marking device and the marking device&#39;s capabilities. 
         [0010]    In some embodiments of the disclosure the blank page indicating routine includes a user answerable option to automatically mark the blank page as intentionally blank, the user&#39;s answer to the option being stored in the driver for all future documents. 
         [0011]    In some embodiments of the disclosure the blank page indicating routine includes a user answerable option to mark the blank page as intentionally blank, the user answerable option being presented to the user when the document is saved or printed. 
         [0012]    In some embodiments of the disclosure the marking device and the processor are parts of a photocopier, and the photocopier scans the document in physical form and converts it to the electronic form. And in some embodiments of the disclosure the blank page indicating routine includes a user answerable option to mark the blank page as intentionally blank, the user answerable option being presented to the user each time a document is copied. 
         [0013]    Another embodiment of the disclosure may include a method for marking intentionally blank pages in a document. The method includes processing a document in an electronic form with a processor; detecting a blank page in the document with a blank page detection routine that is run by the processor; and indicating with an indication that the blank page is an intentionally blank page with a blank page indicating routine that is run by the processor. The indication is configured to be read by a marking device such that the marking device marks the blank page as intentionally blank.

     DETAILED DESCRIPTION 
       [0017]    The concept of detecting blank pages during a copy job or a print job is very useful, especially during the printing or copying of legal or regulatory documents. An author of the document may want to indicate to the reader that the blank page is deliberately blank and that it is not an omission. However, in some systems when a blank page is detected the blank page is not printed and is skipped completely. This removes the separation in the final print product that was originally desired to be indicated by the presence of the blank page. This also removes the separation that is often necessary to start a new section of the document on the desired page for appearance purposes. 
         [0018]    In some systems, a user needs to indicate manually and separately each blank page on which the user desires to include a blank page identifier. Identifiers can be text such as, for example, “This page is intentionally blank” or can be a watermark or other printed identifier. This process can be tedious and can easily lead to errors due to the user having to manually indicate which pages require the identifier. 
         [0019]    In embodiments of the disclosure, when a user submits a copy or print job including one or more blank pages in the original, some systems can detect the blank pages and automatically mark those pages as intentionally left blank using annotation or watermark options. 
         [0020]    For the purposes of this disclosure, a blank page is defined as a page containing no information. Blank pages can be automatically detected using an algorithm or pattern. This can be determined by, for example, measuring pixel intensity variation in the scanned image for a copy or scan job and in the page&#39;s RIP (raster image processor) image for a print job. The information can be measured, for example, by an entropy or projection profile. In particular embodiments, the header and footer areas can be excluded from the region measured to determine whether or not a page is blank. In particular embodiments, a watermark is not considered information when determining whether or not a page is blank. 
         [0021]    In embodiments of the disclosure, the system can provide the user an option to identify the blank pages with a printed identifier. 
         [0022]    By configuring annotation or watermark settings, when such blank pages get detected during copy or print jobs, the system allows marking these pages with printing an annotation text such as, for example, “This page is intentionally left blank”, or another identifier. 
         [0023]      FIG. 1  shows a schematic view of an example of a system in accordance with embodiments of the disclosure. In  FIG. 1 , a processor  100  is capable of running various routines such as, for example the blank page detection and blank page indicating routines discussed above. Processor  100  is connected by a wired or wireless connection  105  to a monitor  110  and by a wired or wireless connection  115  to a keyboard or other entry device  120 . In this example, the blank page detection routine is represented by box  130  and the blank page indicating routine is represented by box  140 . 
         [0024]    Processor  100  is connected to a marking device, in this example a printer,  200  by a wired or wireless connection  150 . In embodiments marking device  200  is a photocopier or other copier that includes a blank page detection routine  230  and a blank page indicating routine  240  in, or connected to, copier  200 . 
         [0025]    Marking device/copier  200  has an output tray  210  for holding pages output by marking device/copier  200 . Marking device/copier  200  also includes a marking unit  250  that marks the pages with the text or other identifier. 
         [0026]    In the case of a copier in accordance with embodiments of the disclosure, a paper document can be fed into the copier as usual but the blank page detection routine detects blank pages and either alerts the user to their presence or automatically adds a marking to the blank pages. In the case of alerting the user to the presence of blank pages, the user has the option to add or to not add a marking to the blank pages. If markings are to be added, the user may be presented with options as to what the marking is. For example, the options may include different text markings and/or different watermarks. In particular embodiments, the copier (or the printer if applicable) can be set to always add markings to blank pages. In particular embodiments, the markings can be a company logo as either text or as a watermark. 
         [0027]    In particular embodiments of the disclosure the blank page indicating routine automatically indicates that the blank pages are to be marked. This can be set as a default in the blank page indicating routine as either mark or don&#39;t mark, and can be changeable by a user. The level of authority needed by change this setting can be limited so that normal users cannot change the setting. In this way, all blank pages will be marked as intentionally blank. 
         [0028]    In particular embodiments, a user is given an option to include the blank page indicia on the detected blank pages.  FIG. 2  shows an example of a user interface through which a user can choose to include the blank page indicia on the blank pages. In  FIG. 2 , monitor  110  presents at  112  the question to the user of whether a blank page marker should be included on blank pages. If question  112  is answered affirmatively then the user is required to indicate whether the marker should be text  116  or a watermark  118 . In this example, if watermark is chosen then two choices of the watermark are presented. Numerous options can be presented for both different text and different watermark markers. 
         [0029]    The blank page detection routine and the blank page indicating routine can be located in the processor in, for example, a word processor program, or can be located in a driver such as, for example, a print driver. In particular embodiments, the blank page detection routine and the blank page indicating routine can be located in different locations. For example, the blank page detection routine can be located in the word processing program and the blank page indicating routine can be located in a print driver or in a printer/copier. 
         [0030]      FIG. 3  shows an example of a method in accordance with embodiments of the disclosure. In  FIG. 3 , at  310  a document is created by, for example, a word processing program. At  320  the document is paginated by, for example, either the word processing program or a pagination routine in a processor or a printer/copier. At  330  blank pages in the document are detected. The blank page detection can take place in the word processing program or in a blank page detection routine in a processor or a printer/copier. At  340  it is determined whether blank pages will be marked as intentionally left blank and, if so, what marking will be added to the blank pages. If it is determined that no markings will be added to the blank pages, then the process stops and normal printing/copying proceeds. If it is determined that markings will be added to the blank pages, then the process proceeds to  350 . At  350  the markings are added to the blank pages. At  360  the document is printed or saved including the blank page markings.
