Definitions

  • a method of providing protected printed information and a paper substrate using the method is provided.
  • This invention relates to a method of providing protected printed information on a paper information-carrying substrate such as a ticket, card, or the like, printed in -accordance with this method.
  • a further drawback is that information or symbols so applied can be breached, at least in part, with relative ease.
  • This problem is solved according to the invention by a method of providing protected printed information which consists of printing said information on a substrate using a colourless ink effective to change the color of a colored ink subsequently applied to said substrate to reveal said information.
  • Figure 1 is a plan view of a card printed with the method of this invention, prior to handling by a wagerer;
  • Figure 2 shows the card of Figure 1 after it has been handled by the wagerer, as made apparent by the inspection check.
  • a paper material substrate for protected information embodying this invention and consisting here in a card for participating in a collective wager.
  • the card is divided into blocks, all indicated at 2, arranged in three columns, each made up of thirteen blocks.
  • EachiColumn has a symbol associated therewith, in this case the symbols ".;1 X 2 ", and a distribution of such symbols is settled by the wager organizer which would be winning on a specific date for the drawing. Of course, said winning distribution will vary with the drawing date. In the example shown, assuming that the card is a winning one, the distribution is as follows (from top to bottom): 1 X X 21 1 X 221 21 X.
  • a graphic symbol 3 a circle in this case, is shown in the blocks of the winning distribution, whereas the remaining blocks are marked with a different symbol 4, a dash in the example illustrated.
  • the circle and dash constitute, in the example under consideration, the information to be protected and which should only be identified by the user after completing the wager card.
  • the aforesaid information is printed on the card using as the printing ink an alkaline solution of sodium disulphite, e. g. a product sold by PELICAN with the trade mark SUPER PIRAT. Mention should be made, as a further example of a suitable colourless ink for this print, of stannous chloride solution.
  • the aforesaid colourless inks by reacting with an aqueous base colored ink of the type specified above, cause a change in their color, discoloring them at least in part, and this property is retained even after repeated treatment with colored ink.
  • the card 1 once printed and made ready for use, has the configuration shown in Figure 1, and may be wagered on different dates, each having a specified key or distribution of the opening symbols appointed by the wager organizer.
  • the user on purchasing the card, will decide about the date on which it should be entered by coloring thirteen blocks, one for each line of blocks on the cardj. according to the distribution of symbols which is valid for the specific drawing date selected.
  • the blocks are colored with an aqueous base ink of the type specified above.
  • the blocks colored by the user carry in Figure 2 the numeral 2a.
  • the card will be regarded as a winning one.
  • other wager rules may be contemplated, which are not a subject-matter of this invention.
  • the disguise attempts are made evident by that the symbol originally printed in invisible ink (dash 4), shows fringes not contemplated in the original print, a sign that a portion of the block has been previously cclored to ascertain the likelihood of a win according to a different distribution of symbols and that, due to the absence of winning symbols from that specific card in connection with that distribution, the card has been wagered again for a different distribution or wager date.
  • a further advantage of the invention is that attempts at breaching on the blocks can be brought out more easily than with prior approaches because, to inspect the contents of a block, the user is to process a broader area thereof, in order to make the outline of the protected symbol visible. Also facilitated is the development of blocks which may be small in size and set close together, because the user has an immediate perception of the surface treated with the colored ink.

Abstract

On décrit un procédé qui sert à obtenir des informations imprimées protégées et qui consiste à imprimer les informations devant être protégées (3, 4) sur un substrat (1) à l'aide d'une encre incolore pouvant modifier la couleur d'une encre colorée appliquée ultérieurement au substrat (1) afin de révéler les informations protégées (3, 4), ainsi qu'un substrat de papier. De multiples informations (3, 4) sont imprimées sur le substrat à des endroits prédéterminés.
