INSTANT TICKET REDUNDANCY VIA MULTI-CHROMATIC 1NDICIA
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. Patent
Application No.
62/243,384, filed October 19, 2015, and U.S. Patent Application No.
15/152,817,

FIELD OF THE INVENTION
[0002] The present invention relates generally to documents,
such as
lottery tickets, having indicia under a Scratch-Off-Coating (SOC), and more
particularly to methods for enhancing the redundancy of the documents while
adding to the aesthetics of the documents.
BACKGROUNQ
00031 Lottery scratch-off or instant games have become a time-honored
method of raising revenue for state and federal governments the world over.
Indeed, the concept of hiding indicia information under a SOC has also been
applied to numerous other products such as commercial contests, telephone card
account numbers, gift cards, etc. Literally, billions of scratch-off products
are printed
every year where the Scratch-Off-Coatings (SOCs) are used to ensure that the
product has not been previously used, played, or modified.
[0004] Typically the indicia are printed using a specialized
high-speed ink
= jet printer or imager with a water-soluble dye. Normally, the indicia are
monochromatic black or in some cases red in color, but in all cases each type
of
indicia is imaged as a discrete spot color,
[0005] This use of single spot color indicia imaging has
repeatedly proven
to be problematic with traditional spot color Inkjet heads partially clogging,
such that
a portion of the indicia prints while other portions do not For example, in
January
2015, a Roswell, New Mexico lottery player believed he won over $500,000 in an
1
ration: 07.08.2017 22:12:43 - 07.08.2017 22:17:26. This page 24 of AMENDED

instant ticket key number match game. The lottery player believed that he was
holding a winning ticket 100 (FIG. 1) because the key number match indicia was
"1"
and the lottery ticket misprint, due to clogged inkjet, made the intended
indicia
numbers of "18" and "13" to appeared to be two occurrences (101 and 102) of
the
winning key match number "1" (i.e., two $250,000 winners) with the intended
second indicia digits barely appearing (101 and 102) on the ticket 100. A
similar
$500,000 misprint due to clogged inkjet heads occurred with the Florida
Lottery
(FIG. 2 ¨ 110) with the ticket holders filing a lawsuit against the lottery
after they
were told their apparent winning ticket was a misprint. Again, in the case of
the
Florida Lottery, the misprinted ticket 110 displayed misprinted key match
indicia
111, which when matched to game indicia 112 readily appeared to be a $500,000
winner. Indeed, there are many other documented cases (e.g., Wisconsin Lottery
apparent $1,000 winning ticket) of instant ticket misprints due to clogged
inkjet
imager heads with some news media and attorneys claiming that the lottery or
the
ticket manufacturer should be forced to pay for the apparent misprinted prize
value.
[0006] Some attempts to mitigate the problem of clogged lottery inkjet
misprints have been attempted with the incorporation of detailed legal
disclaimers,
abbreviated captions of indicia, and the development of elaborate automated
press
monitoring systems ¨ e.g., US Patent 7,665,400 (Duke). However, legal
disclaimers do nothing to mitigate bad press resulting from misprinted lottery
tickets
and so far have not stopped lawsuits. Additionally, most players do not notice
any
indicia captions due to small size and abbreviated spelling ¨ see FIG. 3
magnification of Florida ticket 110' misprinted key match indicia 113 and
associated
caption 114. Automated press monitoring systems, while commendable in theory,
have in practice proved to be both expensive and unreliable ¨ e.g., the
previously
cited New Mexico Lottery misprinted ticket 100 of FIG. 1 and Florida Lottery
misprinted ticket 110 of FIG. 2 were both printed with the support of an
automatic
press monitoring system as disclosed in the cited Duke patent.
[0007] To date, some state jurisdictions have attempted to pass
legislation forcing lotteries or their ticket providers to pay out apparent
prizes on
misprinted tickets with comments like: "That's a real problem because people
are
throwing away tickets all the time that could very well be winning tickets if
these
misprints are out there..." It is therefore highly desirable to develop
techniques and
methodologies for ensuring the redundancy and integrity of scratch-off ticket
indicia.

Ideally, these redundancy mechanisms would also provide added security against
pin-prick attacks of instant tickets where a nefarious person attempts to
identify
winning indicia via a series of small holes on the SOC such that the attacked
ticket
still appears to be intact and unplayed to the untrained eye. Particularly,
these
redundancy and security techniques should enhance the aesthetics of the ticket
or
document rather than detracting from its appearance. The present invention
essentially eliminates or solves problems of misprints or tampered tickets or
other
documents.
SUMMARY OF THE INVENTION
[0008] One aspect of the present invention relates to a redundantly
printed security-enhanced document comprising a substrate and at least two
different printed variable indicia directly or indirectly on the substrate
having a
general area, the at least two different printed variable indicia having at
least first
printed variable indicia printed in the same general area of the substrate as
at least
second printed variable indicia, the at least first printed variable indicia
and the at
least second printed variable indicia being present so as to overlap with or
be
registered so closely together such that failure of the printing of one or
more
portions of either or any of the at least two printed variable indicia does
not alter a
meaning of information represented by variable indicia on the redundantly
printed
security-enhanced document.
[0009] The at least first printed variable indicia and the at least
second
printed variable indicia are printed in different colors, such as or
preferably in two or
four different colors. The colors can be process colors.
[0010] One of the at least first printed variable indicia and the
at least
second printed variable indicia at least partially can comprise numerals and
wherein
another of the at least first printed variable indicia and the at least second
printed
variable indicia at least partially can comprise words.
[0011] One of the at least first printed variable indicia and the
at least
second printed variable indicia at least can comprise drawings or photographs.
[0012] Another aspect of the present invention is a method of
making
a redundantly printed security-enhanced document comprising a substrate having
a
general area and at least two different printed variable indicia directly or
indirectly
on the substrate, the method comprising printing directly or indirectly on the
3
CA 03040656 2019-04-15
WO 2017/070195 PCT/US2016/057677
substrate at least first printed variable indicia and at least second printed
variable
indicia in the same general area of the substrate, and during the printing,
registering and maintaining registration of the at least first printed
variable indicia
and the at least second printed variable indicia so as to overlap with or be
registered so closely together such that failure of the printing of one or
more
portions of either or any of the at least two printed variable indicia does
not alter a
meaning of information represented by variable indicia on the redundantly
printed
security-enhanced document. The method can print the variable indicia to
produce
the redundantly printed enhanced-security document having the features set
forth
above.
[0013] Objects and advantages of the invention will be set forth in
part in
the following description, or may be apparent from the present description, or
may
be learned through practice of the invention.
[0014] In accordance with aspects of the invention, a security-
enhanced
document with a removable SOC is produced, which may be an instant lottery
ticket
in certain embodiments. The document includes any variable imaged indicium
that
determines if the document wins any prize(s) or contains data that is
otherwise
secure under the SOC. Thus, as used herein, "ticket" or "instant lottery
ticket"
includes both lottery tickets and other types of security enhanced documents
using
scratch-off coatings.
[0015] In a first embodiment, the variable indicia are imaged using
all or
some of the standard CMYK (i.e., Cyan, Magenta, Yellow, and blacK) process
colors. In this embodiment, redundancy is achieved via multiple ink
applications
due to the serial application of the individual CMYK process colors.
[0016] In another embodiment, the variable indicia itself is imaged in
one
color with at least one secondary color providing a written description of the
indicia
in the background. Like the first embodiment, this embodiment achieves
redundancy via multiple ink applications. In this particular embodiment, the
indicia
and background colors do not necessarily have to be CMYK.
[0017] In still another embodiment, the variable indicia are imaged
utilizing patterns of multiple colors. Again, redundancy is achieved via
multiple ink
applications.
[0018] In yet another embodiment, the variable indicia are imaged with
an
inverted background color with redundancy achieved via the inverted foreground
4

PCT/US2016/057677
and background different colors. As used herein, "inverted" colored indicia in
the
foreground or background of a printed substrate uses a light-colored
background
with dark-colored foreground or vice versa, or uses different contrasting
colors, or
uses complementary colors or otherwise different colors for the background and
foreground, such that the color indicia in both the foreground and background
are
visible and legible. This embodiment also has the advantage of creating
confusion
coloration as a countermeasure to pin pricking attacks.
[0019] In all of these embodiments, the variable indicia and their
background are composed of at least two separate colors. The essential concept
of
the invention is to provide imaging redundancy since different colors require
different ink applications with the different ink applications providing
redundancy
due to different ink hardware, ink, etc. for each color.
[0020] Described are a number of printing mechanisms and
methodologies that provide practical details for reliably producing redundant
indicia
under a SOC that are immune to failure of any one high speed variable ink
application system. Although the examples provided herein are primarily
related to
instant tickets, it is clear that the same methods are applicable to any type
of
document (e.g., telephone card, prepaid cards, vouchers, bank security
instruments, coupons, etc.) where information is protected by a SOC.

[0048] As used herein, the words "image" or "print' are used
equivalently and mean that whatever indicium or indicia is or are created
directly or
indirectly on any substrate may be done by any known imaging or printing
method
or equipment. Likewise, "imaging" or "printing" describing a method and
"imaged"
or "printed" describing the resulting indicium or indicia are used
equivalently and
correspondingly to "image" or "print."
[0049] As used herein, the terms "multi" or "multiple" or similar
terms
means at least two, and may also mean three, four, or more, for example,
unless
otherwise indicated in the context of the use of the terms.
As used herein, "variable" indicium or indicia refers to imaged indicia which
indicates information relating a property, such as, without limit, a value of
the
8
CA 03040656 2019-04-15
WO 2017/070195 PCT/US2016/057677
document, such as, without limit, a lottery ticket, coupon, commercial game
piece or
the like, where the variable indicium or indicia is or are ultimately hidden
by a SOC
until the information or value is authorized to be seen, such as by a
purchaser of
the document who scratches off the SOC, revealing the variable indicium or
indicia.
[0050] Reference will now be made in detail to examples of the
invention, one or more embodiments of which are illustrated in the drawings.
Each
example is provided by way of explanation of the invention, and not meant as a
limitation of the invention. For example, features illustrated or described as
part of
one embodiment, may be used with another embodiment to yield still a further
embodiment. The present invention encompasses these and other modifications
and variations as come within the scope and spirit of the invention.
[0051] FIG. 4 depicts a first representative example of modified
lottery-
type instant ticket indicia 125 comprised of multiple (i.e., four ¨ CMYK) ink
applications overlaying the same image for redundancy. To better illustrate
the
concept of multi-application printing, redundancy indicia 125 include four
simulated
color misprints ¨ 127 through 130. The correctly printed portions 126, namely
the
decimal point and left half of the units place "0" and "5" numerals as well as
the left
half of the dollar sign "$", of indicia 125 illustrate how the indicia would
appear with
no misprints. The misprints illustrated in indicia 125 are: the right half of
the "$"
symbol 127 missing the cyan ink application, the right half of the "5" numeral
128
missing the magenta ink application, the tens place "0" numeral 129 completely
missing the yellow ink application, and the right half of the units place "0"
numeral
130 missing the black ink application. As is readily apparent in the redundant
variable indicia 125 of FIG. 4, the absence of any one of the CMYK process
colors
still leaves indicia 125 easily readable in its intended form. In fact, it is
somewhat
difficult for one not skilled in the art to detect any failure of ink
applications in indicia
125. Thus, the redundant printing of all of the CMYK colors alleviates any
reasonable misinterpretation of the information conveyed by the variable
indicia
125, namely a value of $5.00.
[0052] Multi-color indicia redundancy can be achieved with fewer
colors,
so long as at least two colors are applied to each indicium. The at least two
redundant colors can be various spot colors and need not comprise the standard
CMYK process colors.

CA 03040656 2019-04-15
WO 2017/070195 PCT/US2016/057677
[0053] FIG. 5 illustrates a second embodiment of a modified lottery-
type
instant ticket indicia providing three examples (150, 160, and 165) of indicia
printing
redundancy via different colors employed for primary indicia (151, 161, and
166
respectively) with a secondary associated indicia caption background (152,
162,
and 167 respectively) comprised of at least one additional color. As shown in
FIG.
5, the primary variable indicia color (151, 161, and 166) can be a spot (i.e.,
individual) or processed color with the primary variable indicia (151, 161,
and 166)
varying in darkness or contrast with respect to the secondary variable indicia
caption background (152, 162, and 167). This is an example of redundancy of
variable indicia, where the same symbol, numeral, word or letters are not
overprinted in the same area, but in the same general area containing the
variable
indicia. As used herein, the term "same general area" means the area of a
document to be printed with redundant variable indicia so that the meaning or
information imparted to the document by the variable indicia is clear.
[0054] Notice that in the embodiments 150, 160, and 165, because of
the
redundant meaning of the variable indicia, failure of any one color to print
in either
the primary (numerical) variable indicia or the secondary background (caption)
variable indicia would not obfuscate the intended meaning of the indicia in a
game.
When it is realized that the secondary background (caption) variable indicia
152,
162, 167 is imaged over or under the respective primary variable indicia 151,
161,
167, as is shown in example 165, it becomes apparent that redundancy is
maintained even if either the primary or secondary variable indicia fail to
print at all.
Another advantage of the examples of FIG. 5 is that the combination of the
primary
and secondary variable indicia may be easier for persons with poor eyesight to
read
and understand the information imparted by the variable indicia on the ticket.
[0055] FIG. 6 is another embodiment of modified lottery-type instant
ticket
indicia 170 with printing redundancy achieved via multiple colors. As shown in
FIG.
6, redundancy is achieved via two different colors; however, with variable
indicia
170 the two different colors or shades that are readily visible when used
together
are utilized for the secondary caption variable indicia 171 (the caption
""FIVE") and
a background color or shade 172 (red) with the primary variable indicia 173
(the
white 15.00") defined by the absence of the background color or shade 172. As
before, a complete or partial failure of either the caption variable indicia
171 or
background color or shade variable indicia 172 would still result in legible
overall
CA 03040656 2019-04-15
WO 2017/070195
PCT/US2016/057677
variable indicia 170 even if the inks of the caption variable indicia 171 and
background variable indicia 172 were monochromatic spot colors.
[0056] FIG. 7 is yet another embodiment of modified lottery-type
instant
ticket variable indicia 180 or 180' comprised of multiple micro-patterned
colors 181
and 182. FIG. 7 is arranged such that the normal size (i.e., non-magnified)
appearance of variable indicia 180 is shown, in contrast to a magnified
example
180' of the same variable indicia180. The normal appearance of variable
indicia
180 results in an overall grayish color. Only under magnification is it
realized that
the variable indicia 180' are in fact comprised of red 181 and green 182
colors,
here, arranged in adjacent vertical stripes, for example. Again, a partial or
complete
failure of either red 181 or green 182 colors would still result in legible
indicia. This
redundancy is maintained if the red 181 and green 182 are spot colors or are
process colors ¨ i.e., red (cyan + yellow) and green (magenta + yellow).
[0057] FIG. 8 is a presently preferred embodiment of modified lottery-
type
instant ticket variable indicia 190 and 195 comprised of inverted primary
foreground
variable indicia colors 191 or 196, for example showing the 15.00"
information, and
background variable indicia colors 192 or 197. As before, a partial or
complete
failure of either the primary variable indicia colors 191 or 196 or the
background
variable indicia colors 192 or 197 would still result in legible overall
variable indicia
190 and 195.
[0058] The relatively low resolution (240 dpi) of and monochromatic
nature of existing variable indicia on standard lottery tickets dictates that
the fonts
for these characters be simple and straightforward so that even consumers with
poor eyesight can readily differentiate between different information imparted
by the
variable indicia. This simplistic representation of information reduces the
amount of
entropy in the image and therefore makes it possible to more easily identify
particular variable indicia with very little visual information, such that
microscopic
pinprick patterns (where the SOC would appear to be substantially intact to
the
unaided eye) can enable pick-out of illicit winners, since the pinprick
patterns would
be more discernible. In the preferred embodiment of FIG. 8, the inversion of
the
variable indicia 191, 192 and 196, 197 would be pseudo randomly distributed
from
ticket to ticket such that there is no indication which version (i.e., 190 or
195) was
imaged on any given unplayed ticket. This pseudorandom distribution of
inverted
variable indicia provides a countermeasure to pinprick attempts to discern
winning
11
CA 03040656 2019-04-15
WO 2017/070195 PCT/US2016/057677
tickets without appearing to have the SOC removed. In other words, with the
pseudorandom distribution of inverted images on a ticket, any would-be
pinprick
attacker would not know if any particular pinhole color revealed was the
foreground
variable indicia 191 or 196 or the associated inverted background variable
indicia
192 or 197. This would be true if the primary foreground variable indicia 191
or 196
and background variable indicia 192 or 197 were spot or processed colors.
[0059] One possible press configuration 250 capable of producing the
redundant variable indicia embodiments of FIG. 4 through FIG. 8 is illustrated
in
FIG. 9. As illustrated in FIG. 9, press configuration 250 shows two redundant
print
heads (e.g., inkjet) 253 and 256 inline and registered on the same web 251
feed.
Web 251 is pulled over rollers 252 and 257 to ensure correct positioning and
registration for the redundant print heads 253 and 256 (respectively) with the
web
immediately routed through driers 254 and 258 after each print head (253 and
256
respectively) to ensure the printed variable indicia does not smear before
contacting a press roller on the same side of the web. Press configuration 250
is
representative of incorporating multicolor redundancy with printed variable
indicia
using drop on demand inkjet technology typically used for producing instant
lottery
tickets.
[0060] A different press configuration 275 is illustrated in FIG. 10
illustrating utilizing multiple print heads 280 to print redundant variable
indicia via an
offset printing process. As illustrated in FIG. 10, four separate print heads
280 for
each of the (CMYK) process colors apply ink to a rotating photo imaging
cylinder
279 where the desired variable indicia is initially formed. Also, typically in
contact
with the photo imaging cylinder is a photo charging unit 276 that applies a
charge to
portions of the photo imaging cylinder which correspond to areas desired for
the
variable indicia. The charged portions of the photo imaging cylinder 279
attract the
ink and form the desired variable indicia pattern on the photo imaging
cylinder 279
for each color in a sequential process. This variable indicia ink pattern is
then
transferred to the blanket cylinder 278 where the process is repeated until
all colors
are transferred to the web substrate 276 via the impression roller 277 forcing
contact of the substrate to the blanket cylinder 278. Thus, redundant variable
indicia ink applications are imaged via a common photo imaging cylinder 279
and
associated blanket cylinder 278 with no requirements for the web to travel to
separate print heads positioned in different locations in the path of web
motion.

[0061] Of course, all press configuration embodiments must ensure that
sufficient registration is maintained between multiple ink or dye applications
such
that the redundantly printed variable indicia appear to be one coherent object
to the
human eye. Thus, it is essential that registration be maintained between the
various
applications of redundant indicia, preferably to between 1 and 1/2 print dot.
[0062] Of course, there are other variations of the disclosed
embodiments
(e.g., process color indicia images comprised of a balance of at least two
different
colors, etc.) that would be apparent to anyone skilled in the art in view of
the
present disclosure, and would be within the parameters of the appended claims.
