## Title
Real time correlation mark images for low memory devices

## Abstract

Methods and systems for providing real time correlation mark images and/or gloss marks. A new font can be created with respect to a prior font, wherein the new font includes a wider foreground than that of the prior font while maintaining the spatial frequency associated with the prior font (one time per font). The new font is then modified to include an inverted modified font by inverting each glyph one time per font and providing an image having the new font. The image is then written and the current color associated with the image is set to white (or to knockout). An operation is then implemented to write on top of the image using the new font.

## Background
TECHNICAL FIELD
Embodiments are generally related to the field of digital imaging. Embodiments also relate to the protection of documents via security measures and preventing the counterfeiting of printed materials.
BACKGROUND OF THE INVENTION
Security is an important concern in the realm of documents and digital production and/or reproduction of the same. Known digital image printing/copying systems produce documents of such high quality that a need has been identified to prevent effective printing/copying of certain documents such as high-value printed items including tickets, financial instruments, security passes, pharmaceutical prescriptions, and the like. Known techniques include printing the original document in a manner such that it includes a “watermark,” using only conventional paper and toner or ink. One such watermarking technique that has been developed and is known to increase document security involves the use and implementation of correlation marks.
Correlation marks offer a unique and simple method for protecting and tracking documents. Based on digital screening technology, correlation marks take advantage of spatial correlations in halftone screens to create a self-authenticating, secure document containing an invisible, hidden image. Using correlation marks, invisible images can be hidden within a normal, visible image, such as a photograph, using specially designed halftone screens. The halftone screens utilized to embed the correlation marks can be used like any traditional halftone screen, no additional image processing is required.
Different from digital watermarking technology, correlation mark technology hides an invisible image during the printing process. No alteration to the original image data is required. And because the hidden mark is inserted during the printing process, each copy of a document can have a unique hidden image.
Hidden images made using correlation marks technology are not visible to the human eye. Such hidden images can be detected either by scanning and processing the printed image or by overlaying a transparency containing a ‘key’ on top of the document to reveal the hidden image. Correlation marks are thus robust to copying and distortion and can be detected in reproductions of the halftone image.
In the area of document security, documents are protected from copying, forging, and counterfeiting using multiple techniques including, but not limited to, watermarking, correlation marks, etc. One approach for document protection involves using standard material such as papers, inks, toners, etc. Typically, however, most security printing companies in the marketplace require special (and expensive) materials. One example of a document requiring security is a prescription where a pharmacist would like to be able to have a high level of confidence that the document is genuine.
The correlation marks shown in FIGS. 1 and 2 are examples of a document security technique that requires a screen or a key to decode. FIG. 1 illustrates a prior art image 1 of correlation marks located above barcodes, and FIG. 2 illustrates a prior art image 2 of correlation marks with respect to a screen.
The approach shown in FIGS. 1-2 generally involves modifying an image to compensate for a lightning effect in later processing steps (the image only needs to be sent to a device one time), creating a pattern ink with the image, adding a vertical and horizontal white space to the image, setting the pattern ink to be the current color (anything written will write in the image with the white space), and writing a gloss (or correlation) mark variable text until the entire image is written. The last step can be repeated N times once per variable data.
One of the primary problems with this approach, however, is that although this technique does work in some production devices and work flows, when implemented in newer applications, this technique fails with an out-of-memory error with respect to target office devices. This problem is caused because the pattern caches (e.g., memory) were not designed for the images from the steps above. Increasing the pattern cache or avoid using it does not solve the issues.
It is therefore believed that an improved correlation mark technique is needed to overcome these problems.

DETAILED DESCRIPTION
The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof.
It will be appreciated that variations of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Also, that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
Reference will now be made in detail to the present embodiments exemplary embodiments) of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In the following description, reference is made to the accompanying drawings that form a part thereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the invention. The following description is, therefore, merely exemplary.
While the invention has been illustrated with respect to one or more implementations, alterations and/or modifications can be made to the illustrated examples without departing from the spirit and scope of the appended claims. In addition, while a particular feature of the invention may have been disclosed with respect to only one of several implementations, such feature may be combined with one or more other features of the other implementations as may be desired and advantageous for any given or particular function. Furthermore, to the extent that the terms “including”, “includes”, “having”, “has”, “with”, or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.” The term “at least one of” is used to mean one or more of the listed items can be selected.
FIG. 3 illustrates a flow chart of operations depicting logical steps of a method 10 for the creation of real time correlation mark images for low memory devices, in accordance with a preferred embodiment. Note that although method 10 is discussed in the context of correlation marks, this approach works equally well for gloss or correlation. The method 10 shown in FIG. 3 can result in the creation of real time correlation and/or gloss mark images in a manner that is not memory intensive and which will function on target devices. Method 10 generally involves two font modifications, one image modification and writing the modified font in a knockout mode. One font modification (e.g., see block 14) improves image quality. Another font modification (e.g., see block 16) allows for the functioning of a knockout mode as discussed in more detail herein. Thus, only one font modification (e.g., a thicker foreground) need be implemented to improve image quality over prior approaches. Note that the operations shown at blocks 14 and 18 improve image quality. To create 1000 diplomas with 1000 variable data strings, for example, however, only one image is required (e.g., see the overall flow/operations of method 10).
Note that as utilized herein, the term knockout (e.g., knockout mode) refers to a portion of an image that has been removed. When two colors overlap, for example, they do not normally print on top of each other. For example, the bottom color is knocked out of—not printed—the area where the other color overlaps. If the overlapping colors were printed, a portion of the image could be potentially over-saturated with ink and could also affect the color of the image. Knockout type is typically text that is knocked out or reversed out of a dark background so that the type appears in the color of the paper.
As indicated at block 12, the process is initiated. Next, as shown at block 14, a step or logical operation can be implemented in which a new font is created with a wider foreground than a current font, while maintaining the spatial frequency (one time per font). Thereafter, as depicted at block 16, a step or logical operation can be processed in which the new font is modified by inverting each glyph (one time per font). Then, as shown at block 18, a step or logical operation can be implemented to modify the image to compensate for lightning effect in later steps operations. That is, the image only needs to be sent to a device one time.
Next, as depicted at block 20, a step or operation can be implemented to write the image. Note that the operations shown at steps 20, 22, and 24 can be repeated N times once per variable data record. As depicted next at block 22, a step or operation can be processed to set the current color to white or to knockout. Then, as indicated at block 24, a step or local operation can be provided to write on top of the image knocking out using the inverted modified font. Following the processing of the operation shown at block 24, a test can be determined, as depicted at block 26, to determine if the operations depicted at blocks 20, 22, and 24 have been repeated N times. If so, the process can terminate, as illustrated at block 28. In a preferred example embodiment, the loop of instructions or operations depicted at blocks 20, 22, and 24 can run on a printer such as, for example, the printing device 204 depicted in FIG. 11.
Not only does the approach of method 10 solve the memory issue discussed previously, but additionally provides better quality images as compared to prior art approaches, due to the operation shown at block 14, which allows more of the original image to remain. Each of these operations will now be explained in more detail with a figure showing the particular step.
This approach can be summarized as follows according to these steps:

    
    
        1) Create new font with a wider foreground than current font maintaining the spatial frequency (one time per font).
        2) Modify the new font by inverting each glyph (one time per font).
        3) Modify the image to compensate for lightning effect in later steps—i.e., the image only needs to be sent to a device one time.
        4) Write the image (*note steps 4-6 are repeated N times once per variable data record).
        5) Set current color to white or to knockout.
        6) Write on top of the image knocking out using our inverted modified font.
    
    


Not only does this approach solve the memory issue, but also provides better quality images as compared to prior techniques, due to the fact that this approach allows more of the original image to remain.
FIG. 4 illustrates an image 4 of an example correlation glyph or mark “A”. FIG. 5 illustrates an image 5 having a new font created with wider foreground and smaller background compared to the current font shown in FIG. 4, in accordance with an embodiment. As shown by image 5 in FIG. 5, a new font is created with a wider foreground (black area) and smaller background (white area) as compared to the current font shown in image 4 of FIG. 4. The center of both the foreground and background is the same for both fonts meaning the frequency is identical. This demonstrates one glyph in the entire font with respect to, for example, the operation shown block 14 of FIG. 3 or step 1 referred to above, wherein a new font is created with a wider foreground than the current font while maintaining the spatial frequency (one time per font).
FIG. 6 illustrates an image 6 of a glyph with the new font depicted in FIG. 5, but inverted, in accordance with an embodiment. The image 6 shown in FIG. 6 is related to the operation depicted in block 16 of FIG. 3 or step 2 described above.
FIGS. 7A and 7B illustrate an imaged darkened one time, in accordance with an embodiment. That is the image 17 is shown in FIG. 7A prior to the darkening effect. Image 19 shown in FIG. 7B represents the same image 17 after subjected to the darkening operation. Note that the operation demonstrated by FIGS. 7A and 7B is an optional step that can improve the image quality by darkening the image one time. This operation corresponds to step 3 described above and block 18 shown in FIG. 3.
The color can then be set to white and the variable text knocks out the image with the font from, for example, FIG. 6. This repeats for all variable data records. FIG. 8 illustrates a zoomed-in view of an image 25, in accordance with an embodiment. FIG. 9 illustrates the same example image 25 having a screen on, in accordance with an example embodiment. Note that the image 19 depicted in FIG. 7B can be written. FIGS. 8-9 depict the same image 25, with the FIG. 8 image zoomed in to show detail and the FIG. 9 having a screen over the right side. Note that the text is available in the entire image, but the glare shown in image 25 of FIG. 9 washes it out in that region.
It can thus be appreciated that the disclosed approach creates real time correlation and gloss mark images in a manner that is not memory intensive (unlike prior approaches) and which will work on target devices. This unique approach involves two font modifications, one image modification and writing the modified font in a knockout mode. One of the font modifications increases image quality over prior approaches. To create 1000 diplomas with 1000 variable data strings with this approach, for example, only one image is required.
