Invention Title: APPARATUS AND METHOD FOR CHECKING PRINTED MATTER The following statement is a full description of this invention, including the best method of performing it known to me/us:
I
2 BACKGROUND OF THE INVENTION a. Field of Invention This invention pertains to an apparatus for checking printed matter, and more particularly for checking continuous or discrete sheets with multiple images, such as banknotes, stamps, securities and so on.
b. Description of the Prior Art Certain printed matter or documents such as banknotes, stamps, securities, travellers checks and so forth require complicated printing procedures to prevent unauthorised duplication, copying or counterfeiting.
Inherently, this material must be printed accurately, since mistakes are taken as an indication that the material is not genuine. Of course complicated printing processes increase the chances of producing printed matter which has mistakes. Thus after completion, these documents must be checked carefully, and the documents with mistakes must be rejected. To the knowledge of the applicants, to date this checking is performed manually, on a one to one basis. The applicants are unaware of any automated systems capable of checking printed matter on line and of rejecting the unaccepted documents.
SUMMARY OF THE INVENTION It is an object of the present invention to provide .o 25 apparatus which will substantially overcome or alleviate i "one or more of the above mentioned problems.
Preferably the present invention provides apparatus for automatically checking and rejecting printed matter.
Preferably the apparatus can perform document S 30 checking continuously on line without the need for human intervention.
.ooee: S• Preferably further the invention provides a flexible oe e system which can perform its function at high speed.
In accordance with one aspect, the invention provides a printed matter checking apparatus comprising: a scanning station for receiving sequentially a S plurality of sheets, each sheet having a plurality of g:\users\melb\P1 7461 .sp 3 documents arranged in two-dimensional array defined by images printed on said sheets, said scanning station generating data descriptive of said images; data processing means receiving sa 4 J data for analysing said data to determine whether said images meet preselected criteria, said data processing means generating identifying signals for identifying one or more document(s) that has or have an image which does not meet said criteria; and a marking station coupled to said data processing means and receiving sequentially sheets from said scanning station, said marking station marking said one or more document with a reject mark, said document(s) being defined by said identifying signals.
In accordance with another aspect, the invention provides a printing apparatus comprising: a printing device for printing a plurality of images arranged in an array on a sheet; scanning means for receiving said sheet from said printing device for generating data descriptive of said images; data processing means for receiving said data and :comparing said data to preselected criteria to determine if each of said images is acceptable, said data processing S 25 means generating identifying signals for identifying one or more image(s) which is/are not acceptable; and marking means for receiving said sheet, and for marking one or more of said image(s) with a reject mark.
S. In accordance with yet another aspect, the invention provides a method of checking images on a plurality of sheets, each sheet having a plurality of images arranged in -a two-dimensional array, comprising the steps of: scanning said sheets sequentially at a scanning station to generate data descriptive of said images; comparing data for each image to preselected criteria to detect an unacceptable image on one sheet, wherein said unacceptable image fails to meet said stafJaen/koopspecO51972 93 DE LA RUE 1 304 3a predetermined criteria; generating identifying signals identifying said unacceptable image on said one sheet which does not meet said criteria; passing said sheets sequentially from said scanning station to a marking station; using said identifying signals at said marking station to identify said unacceptable image on said one sheet; and marking said unacceptable image with a reject mark, whereby uhe remaining images on said one sheet remain unmarked.
Other advantages of the invention shall become apparent from the following description. A printed matter checking apparatus in accordance with one embodiment of the invention includes a scanning station for scanning printed matter and generating data corresponding to the scanned images, microprocessor means for analysing data to determine if these images meet some preselected criteria and a reject station controlled by the microprocessor for rejecting printed matter which does not meet said criteria. The printed matter to be checked consists of images which are printed normally in two dimensional arrays on sheets. These sheets are sequentially fed to the subject apparatus, where they are scanned and if necessary to a reject station for rejection. Preferably, the reject station is adapted to receive specific identifying data from the microprocessor which identifies a specific document on the sheet to be 30 rejected. The identified document is rejected for example by printing thereon a specific word or a message.
ooo ~BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a somewhat schematic diagram of a printed matter checking apparatus constructed in accordance with this invention; Figure 2 shows a somewhat schematic cross-sectional view of the reject station of the apparatus of Figure 2; and 4rs\melb\P 7461 .sp 01,' ers\melb\Pl 7461 .sp Figure 3 shows a plan view of a sheet with a plurality of documents printed thereon.
DETAILED DESCRIPTION OF TEE INVENTION Referring now to the drawings, a plurality of images are printed on a sheet 10 by a printing press. For the sake of simplicity the printing press is i.lustrated by a pair of rollers 12, 14.
These images 16, are normally identical, and are arranged in rows and columns defining a two dimensional array. Figure 3 shows a plan view of the sheet, it being understood that a different set :of images having the same size are printed on the bottom surface 24 of sheet 10 in perfect S: 15 registration with the images 16 to thereby define a plurality of documents, each document bearing one image on top and another on the bottom.
The printed matter checking apparatus may disposedin line with the rollers 12, 14.
e 20 Alternatively, a stack of sheets 10 may be collected after printing and checked for accuracy at a later time.
ooeoo In the embodiment of Figure i, after printing, ooooi S"sheet 10 is forwarded to the printed matter checking apparatus including a scanner station with a set of scanners 18, 20. Scanner 18 scans the top surface 22 of sheet 10 and generates first digital data signals on line 26 representatives of the images 16 on this surface. Scanner 20 scans the bottom surface 24 of sheet 10 and generates a second set of data signals on line 28 representatives of the images on surface 24. Alternatively, sheet 10 may be reversed and run a second time across the scanner 18 to generate the second digital data signals.
Th- digital data on the two lines 26 and 28 are fed to a controller 30. This controller includes a microprocessor which performs high-speed digital analysis on the signals form these lines, and using certain preselected criteria determines if all the images on sheet 10 are acceptable. If these images acceptable, sheet 10 is forwarded without any further manipulation through a reject device 32.
If any one of the images does not meet the preset criteria, the sheet 10 is forwarded for further manipulation by reject station As shown in more detail in Figure 2, reject station 32 includes a plurality of individual marking devices 34. Preferably, these marking 15 devices are aligned in a direction perpendicular to the movement of sheet 10. The number of marking devices 34 is equal to the number of rows of images 16 on sheet 10. Each mark device may consist of an V....impact printer, an ink jet printer or any other 20 device suitable for making a preselected reject mark on single image to identify it as a being rejected.
The reject mark may be any mark easily visible and oo ee clearly identifiable. For example, the reject mark could be a big blob, an oversized X, a bar, the word 25 VOID, and so on.
The controller 30 also includes several other devices which control the movement of the sheets consecutively to and through the scanning station and to and through the reject station. It should be understood that the controller 30 may include a single microprocessor device, or several microprocessor devices, each device being dedicated for a particular function, i.e. checking banknotes, moving the sheets 10, and so on.
I
The controller 30 checks the images on sheet on an individual basis. If a sheet has an image, such as 16' determined by the microprocessor to be unacceptable, the controller 30 provides information to the reject station which identifies the actual image to be rejected. For example if 16' in Figure 3 is found to be bad, as the controller 30 forwards the sheet 10 with the unacceptable image through the reject station. The controller 30 also causes the reject station to print the preselected reject mark on image 16' by activating printer 34' at the appropriate time, i.e. when the portion of sheet is disposed directly below marking device 34'.
Alternatively, station 32 can be provided with 15 a set of printer devices 34 arranged in an array identical to the array of images 16 shown in Figure 3. In this instance when sheet 10 is aligned with the printer arrays, the specific printer 34' corresponding to the unacceptable image is activated 20 thereby marking the unacceptable image with a reject mark.
Of course a sheet 10 may have more than one unacceptable images arranged in a row, in a column, or distributed in a random pattern on the sheet.
The microp: r,-.essor identifies each of the unacceptab :vea and orders the reject station to o mark each of ihe images on the sheet accordingly.
Preferably the reject station is constructed to apply the reject mark only on the top surface 22 of sheet 10 even if an unacceptable image is found on the bottom surface because the object is to mark and identify bad documents, and it is not important to mark the actual bad image.
I Alternatively, the reject station can be provided with two sets of marking devices, one for the top surface and one on the bottom.
After the reject station the sheet 10 is either stacked of delivery or is slit into individual documents and then stacked.
Obviously numerous modifications may be made to this invention without departing from its scope as defined in the appended claims.
