Definitions
- the invention relates to a method of producing scrapable pavers on a support and a support comprising such a paving stone.
- scratchable paving stones means any pattern printed on a support with the aim of being removed by simple scraping with a nail or any object of sufficient hardness, the objective generally being to discover an inscription or a drawing printed under said paving stone.
- the material used for printing has good covering power and sufficient adhesion relative to the support so as not to go away on its own, but insufficient adhesion to be able to resist scratching.
- scratchable pavers of course in the already known field which is the field of games such as lotteries, disposable tickets.
- the depositor is also moving towards other uses, for example all the applications of portable media such as smart cards (bank smart card and / or electronic purse and / or telephone smart card).
- the scratchable pad could be used to cover, for example, a number useful to the user.
- the subject of the invention is a method making it possible to solve the problems of cadence and dynamic change in size, shape and color of the scrapable pad in the context of industrial or other use.
- a more particular subject of the invention is therefore a process for producing scrapable pavers on a support mainly characterized in that it includes the use of an ink jet printing technique.
- the ink used is an ink of the phase change type (Hot Melt, in English terminology).
- the inks used comprise oligomers and polyamides.
- the support on which it is possible to deposit removable pads can be a plastic support such as an integrated circuit card (chip card) whatever either the standard of the card and whatever
- the ink used comprises the ester of a hydrogenated abietic acid (tackifier) and a plasticizing agent.
- the level of ester of hydrogenated abietic acid is included in the composition of the ink from 16.5% to 27% and that of the plasticizing agent will be respectively 15% to 4.5%.
- the support can be made of rigid paper (cardboard) or flexible (paper) pulp.
- printing by ink jet is obtained by one or more printheads controlled as a function of the shape, the size, and / or the color of the block to be produced.
- the print heads used are of the piezoelectric type.
- the subject of the invention is also a support comprising information or graphics on one side and a removable pad masking said information or graphics. It is characterized in that said scrapable pad is made up of justaposed and / or superimposed points of material.
- FIGS. 1a and 1b illustrate an equipment making it possible to implement the method according to the invention
- - Figure 2 illustrates the result obtained on a support such as a smart card in ISO format.
- the method of the invention can be implemented in a different way by the use of one or more inkjet print heads depending on the application.
- one or more heads will be used depending on the shape that one seeks to obtain for the scrapable paver, possibly its size relative to the size of the head and, also depending on the fact that one will want to obtain pavers with a single color or several colors.
- An advantage of the present invention is that the printheads can be positioned in existing production lines for the production of scrapable pavers as a replacement for current solutions.
- One or more inks of the same or more colors will be ejected by the ink jet heads in the passage of the object to be treated, which could therefore be of paper, plastic or other type.
- the inks which can be used for these applications may for example be of the phase change type.
- the main material most commonly used for phase change inkjet applications is wax. Indeed, the characteristics of this material lend themselves very well to the cycles of rise and cooling of temperature necessary for this technology.
- the main uses of this type of ink are generally oriented towards paper or porous support applications which allow good adhesion of the wax-based ink in the fibers of the support.
- the wax has the main defect of not being sufficiently adherent to plastic materials, which generates insufficient resistance to abrasion in the context of this application.
- phase change inks which contain oligomers and polyamides.
- This formulation used by some ink manufacturers, improves adhesion on plastic supports as well as facilitating the production of specific colors necessary for this application.
- the tackifier product is an adhesive agent for ink (in English Tackifier which corresponds to an ester of hydrogenated abietic acid).
- Phase change inks generally have a softening temperature around 90 ° C and physical characteristics compatible with piezo inkjet technology from 130 ° C.
- the applicant preferred to reduce the plasticizing agents which are generally of the polymer type, better suited for plastic applications.
- plasticizing agent used in the context of the invention is Di-isonomyl phthalate.
- the percentages of tackifier and plasticizer in the composition of the ink may be:
- the thickness of ink deposited varies according to the printing resolution, the ink formulation as well as the temperature, the nature of the substrate when the drop reaches the support. In the context of the invention, the thickness deposited varies between 8 to 20 ⁇ m depending on the parameters mentioned above.
- Equipment E allowing inkjet printing of scrapable pavers according to the 1 the invention has been shown schematically in Figures la and lb.
- This equipment will, for example, include a print head In controlled by an electronic control 2 which will include a PG control program adapted to the shape and size of the pattern which it is desired to produce.
- the electronic control 2 is not original in itself, the existing controls for printing machines used in paper printers can be used for example to control this print head.
- the parameters relating to the linear speed of movement of the head, the flow rate d of the ink flowing in the nozzles of the head as well as the program relating to the pattern to be produced in one pass or in several passes of the head on the support, have entered the memory of the print head control program.
- the print head is supplied with ink by a heating tank 3, due to the use of phase change ink based on the temperature variation, this also in a conventional manner.
- the reservoir bears the reference 3 in the figures.
- inkjet heads make it possible to achieve linear printing speeds of the order of one to two meters per second, which greatly exceeds in terms of pace what current technologies are capable of achieving.
- Another very important advantage of the present invention is that the method makes it possible to produce personalized scratch-off pavers because of the addressing capabilities of ink jet heads.
- inkjet heads can be used. Each head will have a specific color in order to produce different graphic effects at high speed and which may also be different from one medium to another by changing the parameter during printing. This change of parameter can be carried out by means of an input-output device, connected to the control electronics 2, referenced 4 in the diagram of FIG.
- FIG. 2 illustrates a support 1 on which a scrapable block P has been printed in accordance with the method of the invention.
- This block P has been placed in a printing zone Z which is defined, with respect to the borders of the card for example, in the program which controls the print head.
- the shape of the block produced as well as the flow of ink to obtain the desired thickness e of the ink which is deposited are also defined in this program.
- FIG. 2 illustrates an exemplary embodiment on a plastic support S such as a smart card in ISO format.
- this support may be a paper or cardboard support produced according to the method of the invention.
- the ink can be replaced by a material and we will then speak of material jet in the broad sense.
- the invention particularly relates to the use of material jet or ink jet techniques in which it is possible to command or control each jet of a drop or blocks of n simultaneous jets of a drop each.
- the support includes information or graphics on one side and a block scratch-off masking said information or graphics.
- the removable pad is made up of dots of material juxtaposed and / or superimposed. These points result from the impact of drops of material, in particular drops of ink projected by jet of material in general or ink jet on the support.
- the dots have a resolution higher than 100 DPI.
- the resolution is between 100 and 600 Dpi.
- the colored dots can form a decorative pattern or information or a security element such as guilloches to increase the interference or camouflage of the masked information.
- the security motif can be regular or random, visible or not from the outside. It can be the same color as the information or graphics affixed to the support so as to be confused with it or it.
- the motif can be directly in contact with, the information or the graphics or be substantially at the same level. It can comprise at least one layer of point of material or ink over a color which is homogeneous or not.
