Definitions
- This invention relates generally to the marking of articles for identification purposes.
- the invention has been devised primarily for use in the marking of pieces of ceramic ware but may be used in relation to other articles.
- Second quality ware is marked with a modified backstamp in which certain areas of the first quality backstamp are removed.
- attempts are sometimes made to alter such modified backstamps by re-introducing copies of the removed areas so as to pass-off the goods as being of first quality.
- bar code It is a common practice in many fields to identify individual articles for stock control and other purposes with a marking in the form of a series of parallel lines or bars, known as a "bar code".
- bar coding of ceramic articles has hitherto proved impracticable due firstly to the problem of applying a bar code to such articles which will retain sufficiently fine detail after firing of the articles during production, and secondly to the fact that the presence of the bar coding on the surface of such articles is not visually acceptable.
- an article having a marking applied to a selected area of the surface of the article,said marking being composed of a vitrifiable material which is indistinguishable from the surface of the article when viewed in visible light but which fluoresces when subjected to ultra-violet light.
- vitrifiable is used herein and in the appended claims to refer to materials which are not decomposed when subjected to temperatures used in the firing of ceramic or glass articles, typically of the order of 450-1300°C.
- visible light is used herein and in the appended claims to refer to light within the visible spectrum.
- the marking may comprise a security coding consisting of a series of identifiable characters.
- the characters may comprise elements of a bar code or alpha numeric characters preferably in computer print form.
- the marking may comprise selected areas of a pattern or of a backstamp applied to the article.
- the article is marked with a backstamp identifying the product ' as originating from a particular manufacturer and having an identity or security marking superimposed thereon.
- each character forming the identification marking comprises alpha-numeric characters in computer print form
- those parts of each character forming the identification marking are preferably constituted by a fluorescent material of a first fluorescent colour, the remaining portions of each character being formed from a non-fluorescent material or from a fluorescent material of a different fluorescing colour.
- fluorescing colour is used herein and in the appended claims to refer to the colour of the fluorescent material when viewed under ultra-violet light and does not refer to the colour of the material when viewed in visible light. Where reference is made to colours other than fluorescing colours such references should be interpreted as referring to colours as they appear in normal light.
- identification marking may be applied over the conventional backstamp traditionally applied to the underside of ceramic articles to identify their manufacturer.
- the fluorescent material may comprise a rare earth material. Suitable examples include lanthanides such as ytterbium and europium. Other suitable materials include vanadates, molybdates, zinc sulphide, copper activated zinc sulphide, uranium oxide, wollastonite and willemite.
- the fluorescent material is preferably incorporated in a decorating ink medium which may be applied to the surface of the article by printing, by means of a decal or transfer or in any other suitable manner at an appropriate stage in the manufacturing process.
- the invention also provides a vitrifiable decorating material for use in applying a marking to a ceramic article, the decorating material comprising a carrier medium, a vitrifiable material which fluoresces when subjected to ultra-violet light, a flux and a pigment or dye, the decorating material being capable of withstanding a firing temperature in the region of 450-1300°C.
- a decal or transfer comprising a carrier sheet, an image layer incorporating a marking in a decorating medium incorporating a vitrifiable material which fluoresces under ultra-violet light, and a support layer releasable from said carrier sheet with said image layer attached thereto to enable the image layer to be transferred to the surface of an article and attached thereto by firing.
- the design layer may be applied between the carrier sheet and the support layer or over the support layer.
- the transfer may incorporate additional protective layers or additional layers for other purposes, for example to facilitate application of the transfer to articles of ware by automatic means.
- the vitrifiable materials may comprise rare earth materials. Suitable examples include lanthanides such as ytterbium and europium. Other suitable materials include vanadates, molybdates, zinc sulphide, copper activated zinc sulphide, uranium oxide, wollastonite and willemite. Said flux is preferably selected from a range of glasses formed from silica, boron, lead oxide, soda or potash.
- a tamper resistant backstamp for an article of ware at least one zone of the backstamp having areas printed in a material which fluoresces when subjected to ultra-violet light, whereby following authorized removal of such zone unauthorized replacement of the removed material is detectable by the absence of the fluorescent areas.
- the invention also provides a method of marking an article comprising applying to a selected area of the surface of the article a marking in a vitrifiable material which is indistinguishable from the surface of the article when viewed in visible light but which fluoresces when subjected to ultra violet light, and subjecting the article with the marking thereon to a firing operation to vitrify said material and bond the marking to the surface of the article.
- Fig. 1 shows a decal or transfer suitable for application to an article of ceramic ware and subsequent glazing and/or firing to fuse the transferred image on to the surface of the ware.
- the transfer comprises a carrier paper 10 surmounted by a release layer 12 serving to facilitate removal of the upper part of the transfer from the carrier sheet 10.
- the release layer may be activated in any desired manner to effect separation, for example by dissolving in water or melting on application of heat.
- an image layer 13 Surmounting the release layer is an image layer 13 the construction of which will be described more fully hereafter.
- the image layer may be covered with a protective layer 14, for example a transparent flux, to increase resistance to tampering after firing.
- the transfer is covered with a final coating layer 15 which acts as a carrier vehicle to maintain the integrity of the image layer during transfer to an article and which volatilizes during subsequent firing.
- the image layer of the transfer incorporates a design, pattern, backstamp or the like to be applied to an article of ceramic ware.
- the image layer incorporates a backstamp in the form of a Trade Mark identifying the products as originating from a particular manufacturer.
- the Trade Mark shown in Fig. 2 is a Registered Trade Mark of Doulton & Company Limited.
- the Trade Mark is printed on to the release layer 12 using a printing medium capable of withstanding the firing temperatures encountered in the production of ceramic,products and incorporates printed wording indicating that the article concerned is security coded.
- the image layer of this transfer incorporates a security coding different parts of which are printed in different materials as shown in Fig. 3 of the drawings.
- the security coding consists of numerals but may equally consist of letters or a combination of numerals or letters.
- the numerals are formed from characters in computer print form and are printed using a printing ink which is substantially transparent when viewed in visible light so that the background colour of the article of ware to which the security marking is to be applied shows through the marking in visible light. Consequently save for slight projection of the characters above the surrounding surface they are not discernible to the naked eye when applied to the article.
- the characters are printed as digits in computer print form they appear, if discernible, by virtue of their projection above the surrounding surface, to consist of a series of the numeral "8" as shown in Fig. 3C. Since many ceramic articles are translucent the opacities of the printing inks employed are preferably substantially the same such that the marking also appears as a series of "8"'s when viewed in light transmitted through the article from a light source placed behind or within it.
- Those portions of the coding shown in Fig. 3A of the drawings are printed using a printing medium incorporating products which fluoresce in a selected colour under ultra-violet light.
- Those portions of the security coding shown in Fig. 3B of the drawings are also printed in a material which fluoresces under ultra-violet light but which fluoresces in a different colour. Consequently when the security marking is subjected to ultra-violet light the marking becomes immediately readable as the series of numbers shown in Fig. 3B, the remaining portions showing as a different colour and not contributing to identification of the marking.
- the fluorescent materials employed in the printing medium may comprise rare earth materials. Suitable examples include lanthanides such as ytterbium and europium. Other suitable materials include vanadates, molybdates, zinc sulphide, copper activated zinc sulphide, uranium oxide, wollastonite and willemite. The materials are incorporated in the decorating medium in such ranges and proportions as to produce materials which are essentially transparent when viewed in visible light but fluoresce in the selected different colours when viewed under ultra-violet light.
- printing inks for each part of the coding are formed from a mixture of 15-25% by weight of a flux material consisting of or incorporating for example, lead oxide, boron, flint or other forms of silica and 45-75% by weight of a mixture of fluorescent materials selected from those referred to above.
- the balance of the composition consists of pigment or dye and a diluent or carrier such as an alkyd resin which is burnt off during subsequent firing.
- Different fluorescent materials are incorporated in the two inks so that the parts of the markings shown in Figs 3A and 3B will fluoresce in different colours.
- Printing of the respective parts of the security coding may be effected using any suitable technique such as screen printing or the like, and following printing of the image layer the transfer is completed by application of protective and coating layers as described with reference to Fig. 1. Thereafter the transfer is released from the carrier sheet, applied to the surface of the article in a suitable position, and subsequently fired. The transfer may be applied to the -"biscuit" fired article prior to glazing and subsequent firing or may be applied after glazing and subjected to a subsequent "on glaze” firing.
- the security marking may be applied at any desired part of the article but for maximum effectiveness it is preferred that the security marking be applied over the conventional backstamp.
- Fig. 4 of the drawings which illustrates the appearance of such a marking when viewed through ultra-violet light.
- the marking is produced in the manner described with reference to Figs. 3A and 38 but is placed over the backstamp after the latter has been applied and either before or after subsequent glazing and final firing. Tampering with a marking of this kind is extremely difficult since attempts to tamper with the security marking inevitably result in defacing of the backstamp thereby making it immediately apparent that the article has been interferred with.
- the identification marking comprises a bar coding consisting of a series of parallel bars of equal height but of different width.
- the bars or the spaces between them are printed in a material which fluoresces under ultra-violet light.
- they may be formed by printing bars in non-fluorescent material on to a block of fluorescent material, thereby producing a series of alternating fluorescent and non-fluorescent bars. In this way when viewed under visible light the coding is not readily visible.
- the markings fluoresce to define the coding. Tampering is rendered difficult as it would require application of fluorescent materials and subsequent heating or firing thereby rendering the changes discernible'and less permanent than the original marking.
- the spaces between the bars may be printed in a non-fluorescent material to minimize the extent to which the bar code would be recognizable as such if discernible due to projection from the surface of the article. Still further security may be attained by superimposing bar coded identification markings of this kind on a backstamp in the manner shown in Fig. 4 of the drawings.
- the bars may be replaced by a series of concentric circles alternately fluorescent and non-fluorescent.
- Fig. 6 of the drawings shows a further embodiment adapted to prevent tampering with ware which has already had an altered backstamp applied thereto.
- products of second quality are marketed bearing a modified backstamp in which some information appears but other details have been removed in order to enable the ware to be distinguished from first quality goods. Attempts are sometimes made to reinstate the material removed from such backstamps in order to deceive purchasers into the belief that the goods are of first quality.
- the arrangement shown in Fig. 6 of the drawings assists in preventing tampering of this kind by utilizing as a normal first quality backstamp a device in which certain regions such as, for example, those indicated at 20 are formed of vitrifiable material which fluoresces under ultra-violet light.
- identification marking may be applied to a different area of the product.
- ultra-violet fluorescent materials of different colours to form different portions of the identification marking a single colour of fluorescent material may be employed in combination with a non-fluorescent material.
- Identification codes may also be applied using alpha-numeric characters not in computer print form or using other characters or symbols.
