Definitions

  • the present invention relates to game tokens also called casino chips.
  • game token hears anything that can be used in a playroom and representing a nominal value predetermined or not, whether it's a disc-shaped token itself or a game board generally representative of a high stake.
  • These tokens are classified into two families depending on the type of games they are used for, "French or European” tokens and "American” tokens, all these tokens being with or without predetermined value. Generally these tokens are made in rigid plastic and resistant to soiling and scratched.
  • marking itself, it is possible to distinguish the marking in thickness or in volume (for example mass marking with or without insert, engraving, etc.), marking a surface (by example printing by mono or multichrome screen printing).
  • marking a surface by example printing by mono or multichrome screen printing.
  • the invention relates more particularly to marking surface, it being understood that the surface marking can be done on a surface inside the token (e.g. for tokens and plates "European” made of plastic sheets laminated).
  • Another technique also used for marking surface of game tokens is to print a decoration (for example by screen printing) on the internal face a transparent plastic plate or translucent, smooth or granitized (for example in polycarbonate) which is then glued to the bottom of a corresponding cavity provided on one face of the token.
  • a decoration for example by screen printing
  • smooth or granitized for example in polycarbonate
  • the document EP-A-0365018 describes an identity card in thin plastic with flat faces in the format of a credit card and intended to authenticate the signature of its bearer. To allow customization of the card, this one has on one of these faces a field of rectangular signature made of a layer of very weak thickness (of the order of 10 ⁇ m) of a material likely to permanently receive ink of ballpoint pen.
  • This signature field filed by screen printing, hot stamp or pad printing is covered with a guilloche security print and left free to access for signature by the card holder.
  • the face of the card except the signature field, receives a mask of varnish with a thickness of 10 ⁇ m substantially equal to that of the signature field layer so as to keep the flatness of the face of the card, flatness which can be further improved by a final operation of stratification.
  • This arrangement is intended for protection of personalizable objects with personalization unique like credit cards and aims to facilitate the detection of fraudulent alteration of the signature carried by the signature field.
  • the invention provides a token or a game plate or a token or plate of similar shape and structure, according to claim 1.
  • the token or the game plate or a token or form plate and analogous structure, having a substantially face flat with a substantially flat bottom cavity is characterized in that the bottom carries a decoration produced by at least one pad printing operation with ink and covered with at least one layer of protective varnish.
  • the combination of varnish with the decoration makes it possible to obtain visual effects and / or provide physical protection necessary for the decor.
  • the advantages provided by the deposit of a varnish of cover one can cite better resistance to wear and scratches and good protection against forgery.
  • the arrangement of the decoration on the bottom of the cavity obtained by the use of pad printing improves still the protective capacity of the decor.
  • the external part of the edge of the cavity has a chamfer limiting deposit and attachment of dirt on the central part of the token and facilitating the marking of the periphery of the cavity by the ink pad.
  • the surface layer of the decoration (ink or varnish) has non-stick properties for prevent fraudulent over-marking.
  • the invention also relates to a token or a plate of game or token or plate of form and structure analogs according to claim 19.
  • at least one face of the token has a softened edge, such as a chamfer or rounding, the edge with a softened profile being marked by pad printing by the same marking operation of the face so as to achieve simultaneous marking at least partial of the token edge. Thanks to this arrangement, it is possible to mark both sides and the edge of the token in two operations instead of three. So the pad printing allows direct marking on the edge of the token (e.g. marking a barcode), which today cannot be obtained by other markings of surface mentioned above.
  • the decor by pad printing is done in multi-color for example four-color printing, especially with more or less inks less transparent.
  • the final color image of the decor obtained by pad printing consists of the complementarity of monochrome images, each of these monochrome intermediate images being engraved on clichés. After inking the plates, a stamp comes recover the ink from these snaps by pressure, for the deposit entirely by pressing on the token to be marked.
  • pad printing allows without particular difficulty the use of very fine shots, greater than 150 points / inch, which increases, in addition to the quality of the decor, the security nature of the token.
  • Advantageously marking the decoration by pad printing is preceded by the deposit, in particular by pad printing, a primer to improve the surface condition support of the pad-printed decoration and / or facilitate the adhesion of the decor and / or create a background.
  • the decor obtained by pad printing is done with at least one ink or varnish revealable under ultraviolet radiation.
  • the decoration obtained by pad printing is performed with at least one layer of ink / varnish mixture. This feature allows between others to get a brighter marking and harden the layer forming the decoration.
  • the marking of the decoration is obtained by at least one pad printing operation ink with a visual effect or pattern by at least one layer of varnish deposited by pad printing either in the area of the marking or between two printing layers of the latter.
  • the pattern can be placed on all (for example a checkerboard) or part decoration (marking the name of the casino with a varnish more or less shiny and / or revealable under U.V.).
  • the decoration obtained by pad printing is carried out in part by one or more varnish layers of various visual appearance chosen from matt varnishes, gloss varnishes, tinted varnishes, varnishes iridescent, pearly varnish, glitter varnish, granite varnish, aging varnish and crackle varnish.
  • This technique allows to obtain a particular visual aspect for the decor and provides good protection against fraudulent reproductions.
  • the layer of varnish associated with the decoration is deposited in cover of said decoration obtained by pad printing and has a thickness at least equal to 20 ⁇ m.
  • the layer of cover varnish present a thickness between 50 and 100 ⁇ m thus ensuring to the decor a protective layer of high resistance mechanical.
  • the layer of varnish cover is deposited on said decor by spraying, soaking or depositing with a drop or curtain.
  • the varnish of the cover layer consists of one or more synthetic resins powdered with hard materials for example silica-based materials.
  • the varnish of the cover layer consists of one or several synthetic resins loaded with materials giving the varnish non-slip properties, by example of materials based on elastomer or wax.
  • the installation of the layer of cover varnish on the decor is preceded a token coding and / or numbering operation, incremented or not, by inkjet or laser printing, hot stamping or pad printing over the decoration.
  • the invention also relates to various methods of marking by pad printing at least one of the sides or edge of a game token and the application of pad printing to marking and decoration of game tokens.
  • At least one of the sides or edge of a token or game board or a token of similar shape and structure comprising at least one flat-bottom cavity by marking on the bottom of the cavity of a decoration by at least one pad printing operation with ink and then laying in cover covering at least one layer of varnish protection.
  • a decor partly by pad printing of one or more varnish layers of various visual appearance chosen from matt varnishes, gloss varnishes, tinted varnishes, varnishes iridescent, pearly varnish, glitter varnish, granite varnish, aging varnish and crackle varnish.
  • the decoration is marked with at least one pad printing operation of a mixture ink / varnish.
  • the marking is carried out. of a decoration by at least one pad printing operation ink with a visual effect or pattern by at least one layer of varnish deposited by pad printing either in surface area of decoration or between two decor ink printing layers.
  • the invention also relates to a marking method at least one of the faces of a token or game plate or a token or plate of similar shape and structure, having a smooth profile edge such as a chamfer or rounded, characterized in that said profile edge softened is marked by pad printing by the same operation of marking said face so as to achieve the simultaneous marking of at least part of the section token or plate.
  • the invention is applicable to tokens and similar plates in their structures (including their forms), their purposes and their terms of use such as tokens prepayment, tokens and / or access plates, countermarks, etc.
  • FIG. 1 illustrates the principle of such a setting installation of the invention.
  • the reference 10 represents a horizontal frame on which moves in a step-by-step movement of a ribbon, each of which section 12 is provided with a cell 14 intended for receive a token to be marked 16 (the face to be marked very slightly protruding from the surface of section 12 ribbon).
  • the token 16 with flat faces is made by injecting material plastic.
  • the section tape 12 is replaced by a tray turning or carousel.
  • Tokens 16 pass successively in front of a movable ink pad 18 according to alternative vertical movements.
  • Stamp 18 has a deformable head 19 made of synthetic material (silicone material), in this case with a conical tip.
  • a plate holder 20 is also susceptible to movement alternating between the vertical of the buffer 18 (position 20) and the vertical of an ink tank 22 (position 20 ').
  • the actual pad printing operation is performed as follows. After inking the plate (position 20 ') the plate holder is moved in the position 20. A first vertical movement down from stamp 18 allows the ink (or varnish) to be recovered by one touch. After raising buffer 18 and removing of the plate holder (towards position 20 '), the stamp 18 undergoes a second vertical downward movement to deposit ink (or varnish) by simply pressing the face opposite the token 16 to be marked. We realize thus marking an image (final or intermediate) monochrome.
  • the final image of the decor is constituted by complementarity and / or superposition single color images, each of these images intermediaries being engraved on separate plates.
  • multi-color marking that is several movable plate holders or a series of units of monochrome pad printing. Inks are generally very fluids, with a certain character of transparency and able to dry quickly to allow next operation of marking in another color without risk of mixing successive impressions of different colors (around 2 seconds between two markings).
  • the inks used are multiple colors: by blue, green, red and black example for the four-color process.
  • Metallic inks are also used for example, metallic gray, to give special effects on image: moire, iridescent, pearly effect, etc.
  • the decoration is associated a layer of varnish by decorating with pad printing with at least one layer of mixture ink / varnish allowing to obtain a decoration shiny and / or more resistant to wear.
  • pad printing is carried out varnish with matt / glossy patterns (for example backgrounds solid such as checkerboards or inscriptions such the name of the casino, the value of the chip, etc.) very difficult to reproduce by photo (therefore very security). These patterns are made by filing by pad printing of one or more layers of varnish either in surface area between two printing layers of the decor deposited by pad printing in ink.
  • pad printing allows the use of frames on the clichés, which is very appreciated for the impression of decor like "photography".
  • pad printing allows without difficulty particular the use of very fine wefts, greater than 150 dots / inch, which increases, in addition to quality of the decor, the security character of the token, effect the difficulty of reproduction (especially for unauthorized reproductions) grows with the finesse of the frame.
  • the decoration obtained by pad printing, with at least one ink pad printing operation is protected by covering with a layer of protective varnish, such than a transparent varnish, for example matt, satin or brilliant.
  • a layer of protective varnish such than a transparent varnish, for example matt, satin or brilliant.
  • the layer of cover varnish has a thickness between 50 and 100 ⁇ m to ensure good resistance to wear and soiling.
  • the deposit by soaking, spraying or curtaining is well suited to the cover of a decoration extending over a full face a token (see for example flat-faced tokens 16 so-called “full face” decor and tokens 30) while the drip deposit is well suited for covering a padprinted decoration in bottom of cavity (see for example the cavity token illustrated in Figure 3b).
  • cover varnishes provide protection of a hardness at least equivalent to that plastic material used for the token (between 70 and 85 in Shore D hardness equivalent to the top of level 2 of the MOHS scale (mineralogists scale)).
  • higher hardnesses can be obtained with polyurethane and / or acrylic varnishes curable with UV rays or varnishes one or more synthetic resins charged with hard materials powder for example based materials silica.
  • some cover varnishes consist of one or more synthetic resins loaded with materials giving properties to the varnish non-slip, e.g. base materials elastomer or wax.
  • the marking can receive a "non-stick" coating using silicone or fluorinated (PTFE) inks and varnishes for avoid overprinting and / or falsification of the decor.
  • PTFE silicone or fluorinated
  • the installation of the varnish of cover on the decoration of the token is preceded by a operation of marking a coding and / or a numbering, incremented or not, by jet printing ink or laser, hot stamping or pad printing over the decoration, the latter being obtainable by any suitable process (in particular type decor padprinted or hologram).
  • a coding by example barcode
  • lot number by / or serial
  • this number may occasionally be incremented.
  • This coding and / or this numbering can remain discreet by the use of UV-revealing ink.
  • certain inks (or varnishes) used in pad printing for the decor receive pigments likely to reveal themselves under ultraviolet radiation.
  • the holding of the decoration obtained by pad printing can be improved by various techniques before or after marking and adapted to the support material of the decoration of the token (synthetic material, metal of the central insert, etc.), for example: before marking by treatment mechanical (sandblasting), chemical treatment (acid), by physical treatment (CORONA effect, flaming), after marking by heat treatment, drying, radiation (infrared or U.V.), or by the use of inks polymerizable or sublimable (with an effect of penetration into the mass of the plastic material).

  • pad printing makes it possible to obtain a marking of good quality tokens with a great complexity of the decor (in particular by taking advantage of the transparency of the inks and of the matt / shiny appearance of the varnishes) and the possibility of additional security operations. , all using the same basic tool, the pad printing unit.
  • This feature the low tooling costs, the flexibility of the technique and the high rates obtained by this printing method (up to 3000 chips / hour) make it a very economical method of marking gaming chips.
  • the decoration by pad printing within the scope of the present invention can be from the simplest to the most complex and consisting of drawings, signs, brands, characters, letters, numbers, bar codes etc., all susceptible of graphic representation taken individually or in combination.
  • the complete marking of a token is produced in three prints (one per side and one for the edge of the token):

  • a complete token marking by pad printing in two operations.
  • the edge of at least one side of the token is changed (relative to the right edge usual) to present a softened profile, such as chamfer or rounding.
  • Figures 2a and 2b illustrate the marking of a token 30 (by way of example not restrictive, made of injected plastic) the two substantially flat faces 32, 32 ′ have each a peripheral chamfer 34, 34 '(according to a angle of about 60 ° with the corresponding face), the token being otherwise symmetrical with respect to the plane horizontal PP 'parallel to the faces 32, 32'.
  • the depth of the cell 36 of the carrier tape of the token 38 is slightly less (by a few 1/10 of a mm) than the half thickness of the token 30, thus allowing total inking of the conical chamfer 34 when the head deformable 42 of pad 40 is compressed (with slight protrusion of the rim 44 of the head 42 beyond the plane median PP '). So therefore, each printing operation allows the marking of a face and a half-slice of the token.
  • the invention also relates to the marking of tokens whose faces substantially flat each has a cavity central, usually circular, deep of a few tenths of a millimeter for example the monoblock tokens injected or tokens obtained by successive injections of plastics different colors to get a first decor multicolored in the mass of the token (for example overmolding of a peripheral crown on a core substantially flat median obtained first injection).
  • marking by pad printing (and varnish protection cover or wafer) of these cavity tokens without insert is very close if not identical to pad printing marking described in detail below as part of the marking of cavity tokens with insert.
