Definitions
- the present invention relates to several methods making it possible to make an impression erasable, indelible and cleanable, selectively, to laminate it automatically and to increase its physical or computer preservation.
- the present invention aims to overcome these drawbacks by proposing new methods allowing mechanical and / or manual printing, the property of being selectively and simultaneously erasable, indelible, cleanable, washable and modifiable.
- the present invention relates to methods for the use of substrates intended for writing, drawing and printing, these substrates being originally made of a natural or synthetic material, for example a paper or a plastic material. , characterized in that the printing will be carried out on an impermeable material and may include a micro-porosity which may include several degrees, for example up to eight, measurable according to the reference index in the material, allowing it to be applied to will print, design or write, erasable or indelible If the material used has a hydrophilic coating, it will be covered after printing with a transparent waterproof coating.
- the properties being obtained simultaneously and selectively as well as in an absolute or relative manner, depending on the inks, the supports, the methods of use and the solvents (dry, with water, with chemical solvents or with hydrocarbons).
- the absolute way being that the inking will not be altered by the use of almost all solvents, including the most powerful.
- the inking may or may not be covered. From degree 0, comparable to a smooth surface, you can write with a ballpoint pen and with specific graphic tools (instant drying). When rapid drying is not essential, all other means of marking may be considered (markers, markers, aerosols, stencils, etc.).
- This support being also usable in printing machines, printers, plotters, fax machines and photocopiers or typewriters (unitary or combined devices)
- Mechanical or manual printing can be carried out on the substrate on one or two sides as well as on one side by reversing the direction of the image. These prints can be done on one or two levels including laminating. A protective coating can also be applied to these prints; these being carried out by all the techniques of printing and office automation as well as by artisanal and artistic processes. Other parameters apart from the inking, will determine the best porosity:
- the plastics will be of a thermoplastic and thermosetting and elastomeric nature (plasticization). Most plastics may be suitable depending on the method of erasure and use. Plastics will be used in a solid or pulverulent, hot-melt form. In general, we will choose plastics whose molecular composition will block the diffusion of ink in the material (those affected by erasure), as well as those not being alterable by the solvent solution or another solution and corresponding to the specific characteristics of the use. We will also remember the mixture of resins and cellulose. For the substrates having more than one layer, not all of them will necessarily be tinted. We will also retain laminating (complex), coating extrusion, one or two extruded faces. The materials used can be paper plus plastic or plastic plus plastic, for example polyester, HD polyethylene, hot or cold embossed When hot, the density will be improved. These substrates receiving a surface treatment on one or two faces, these being identical or different
- One or the other face will be used, the first being able to be of the same nature or different by its coating or without, being able to have different degrees of porosity including on the same face; these substrates being in color or not or in different colors, the substrate may be perforated or not or precut and be in the form of sheets, rolls, coils, screens.
- the support can be glued to another support and be cut out regularly or not, for example with labels or other elements. Certain elements can also be made up of several parts. I t may be transparent, translucent or opaque, screened or illustrated flexible or rigid and of all formats.
- a face which can be magnetic as well as the ink, as well as a possible erasing medium. You can optionally glue the contours or side (s) of the front and back so that you can use them on one side or the other.
- the substrate may be erased or cleaned by means of a chemical solution comprising at least one or more solvents. It will also be possible to envisage a mechanical faceting machine (roller or other) automatic or semi-automatic of reduced size (office) or more. important for professional use. Surface treatment processes
- the present invention makes it possible to erase or clean all or part of a surface written or drawn on a plastic or cellulosic support, whether these are thermoplastics or thermosets, whether in films, sheets or plates.
- the subject of the invention is also the substrates prepared by the process or any one of these embodiments, specified above and developed in more detail below.
- the degree of porosity chosen will be obtained by one or more processes and their possible combinations, we can cite for example: embossing or stamping, micro-perforations, abrasion, weaving, molding and finally the surface coating and combinations of these different processes with one another or any other process giving porosity for this purpose. It will also be possible to silicone certain surf aces.
- the porosity will be obtained hot or cold, depending on several parameters (the material can be etched symmetrically or not), the density (ranging from micro to macro), the hollow and the relief, the penetration angle, the chosen material as well as its thickness.
- the porosity being made of points or lines, lines or curves, lines or segments and all other geometric combinations, whether it is each of the elements or its whole; giving it the desired porosity.
- representative shapes such as drawings, patterns or the like will also be produced.
- a drawing without ink
- a drawing will be printed, the outline of which will be obtained by embossing a hard imprint on the outside and a flexible, high-density imprint on the inside.
- a hot calendering of imprint (s) of a flexible material on the polyethylene side and hard on the polyester side we can make on the same surface areas with all the porosity degrees from 0 to 8.
- a flexible material such as wool, an artificial or synthetic woven (example wool or cotton, polyester or polyamide), velvet, canvas, etc.
- a second calendering cylinder (or press) is used, a hard material such as a sanded cylinder, a hard plastic or a bakelite, a grainy metal, or any other mineral or organic material will be adapted.
- the unnatural porosity will be obtained by different methods. Abrasion will be obtained by physical and / or chemical sanding of the structure. The micro-perforations will be made by press or calendering. Micro-impacts (alveolar) will be by the collision of electronic particles on the substrate (electron or ion bombardment). Embossing or stamping by calendering or by hot or cold press. As a general rule, physical and / or chemical or mechanical and / or electrical and / or electronic, thermal and electromagnetic radiation and other processes and their combinations may be used. Another method consisting of a combination of these.
- light sanding or embossing of a smooth substrate with or without coating, abrasion of a molded surface or vice versa will be carried out using micro-perforations and smoothing, or double hot and / or cold embossing or double hot embossing of two materials, one flexible, the other hard on the same surface. All of these methods make it possible to attenuate the surface gloss and to make it more receptive to inking and sizing. Other multiple combinations are also possible, whether hot or cold.
- the porosity and selective printing properties of the substrate can be carried out at any time, including by the user
- the surface structure being produced by coating the substrate by mechanical application 1) of a hydrophilic coating, 2) of printing varnish (also hydrophilic), 3) and by the user of a layer of varnish or of latex varnish, 4) of a lacquer or of a thermosetting or thermoplastic resin in printing or covering surfaces thereof. All of these materials can be sprayed hot or not, possibly with simultaneous calendering or using a press.
- the degrees of porosity allowing when using a dry erasable graphic tool to make it more and more difficult until making its erasure impossible (dry).
- the surface will therefore be adapted according to parameters related to the speed of the erasing to the hold of the ink and to the surface area. These degrees of porosity do not intervene in the indelible character of the surface apart from the dry erasable inking.
- the color of the substrates will be either in the mass or in the coating. Colors ranging from light to dark. A background pattern may or may not illustrate this. We will adapt the shades darkened by light or also dark inks but whose contrast will allow excellent visibility and legibility in office use and printing. For example a monochrome print (other than black ink) adapted to the support also according to its color.
- Another possibility consists in applying to the substrate an equally hydrophilic printing varnish.
- This type of coating can be over all or part of the surface. This being applied by printing techniques downstream of manufacturing (as a general rule) This coating can be damaged by chemical agents and / or water. These two types of coating can receive an additional permeable layer of varnish or resins and will be chosen so as to be preferably chemically inert and in any case compatible with the chemical agents proposed. Varnish or resins will be applied by all existing processes including vaporization and sublimation accompanied by a possible calendering Varnish or resins which can then be passed through the oven or subjected to electromagnetic radiation. This type of coating can be applied to a microporous surface or better having an appropriate particle size allowing by pressure application to microperforate the coating and to make each micro-element permeable (by friction)
- This layer must have the properties of being: coalescent, solvent, film-forming, and incidentally allow manual printing and / or mechanical, in particular ball, liquid, felt inks, etc.
- This layer can be applied at any time and on all plastic or paper substrates, smoothed, calendered or glued
- the substrate receives a surf ace treatment in order to make it micro porous.
- the substrate receives a surface coating in order to make it hydrophilic either by printing varnish or hydrophilic coating, of different natures
- the substrate receives a double coating making it permeable and hydrophilic (by friction).
- a varnish whose formula will be composed of the IBMA copolymer about 25 to 30% (percentage may vary depending on the case) to which we will add a cocktail of solvents (true, latent and diluents) including white spi ⁇ t, ethyl acetate, essences C and F and a plasticizer as well as polyaminoamide salts.
- solvents true, latent and diluents
- white spi ⁇ t ethyl acetate
- essences C and F a plasticizer
- plasticizer plasticizer
- the substrate can be completely or selectively worked depending on the inks and solvent used 2) Same, except and depending on the degree of porosity, which cannot be erased dry or difficult.
- the same surface can have different properties depending on the porosity (dry erase).
- the substrate will not be erasable or very difficult (depending on the nature of the hydrophilic coating). 4) The substrate will be erasable for surface inking and erasable if the hydrophilic layer is impregnated.
- the substrate will be erasable and the surface reprocessed if using a plasticizing varnish.
- Example dry or pasty ink of the pastel type (soft, in oil with wax, based on gum or resin);
- Thick ink example ballpoint ink, which may include different pitches, dext ⁇ ne, petroleum jelly, resin, solvents, etc.
- Oily or gel inks (oils or alkyds, oleoglycerophatic, or soft urethanes, or fatty oleoepoxides, pigments, solvents;
- Solvent inks (resins + solvent + pigments); Water based inks (acrylic resins + dyes);
- Alcohol inks (resins + pigments + alcohol);
- the same ink on the same surface may have a time different drying depending on the method of use, for example transferred to a graphic tool or using an inkjet machine or in printing possibly requiring thermal support.
- Water erasable inks for example transferred to a graphic tool or using an inkjet machine or in printing possibly requiring thermal support.
- water erasable inks must contain constituents whatever they are, water soluble, for example pure gums or resin gums, alginate, dext ⁇ nc, shellac, casein, polyvinyl alcohols, methylcelluloses, xanthan gums etc; as well as dyes and solvents.
- inks Liquid or pulverulent ink (electrostatic), dry ink for dry or direct transfer (for example ribbon), solid ink for thermal transfer or sublimation or, 2-body ink (with a crosslinking agent (hardener) , example of resins which may be suitable: polyisocyanates, epoxides, alkyds, etc. ink crosslinkable by electromagnetic radiation, for example, UV or ionizing radiation.
- inks will be used in printing on non-hydrophilic supports, in particular in flexography and gravure printing.
- two body inks the constituents being mixed at the time of use, eg polyester resins, epoxies modified by (polyamines, polyamides and dnsocyanates), and aminoplasts, etc.
- Selective inking is possible in several ways; first of all, inking hey with indelible or erasable or selectively cleanable properties, whether these properties are qualified as absolute or relative, by the use of the same solvent on two different inks or two solvents on a same ink and on a non-hydrophilic support.
- First case By taking for example, a formulation of toner ink x or other conventional inks without necessarily having specific properties, this one not being altered by the solvent y whereas the same formulation x will be it by the solvent y '.
- Example- the ink formulation x 'will be indelible with solvent y and the same ink formulation x' erasable with solvent y '(ink x' + solvent selectively cleanable) and ink x 'plus solvent y' non-selectively erasable.
- Selective inking is also linked to the choice of surface, for example on two different supports, one of which will have a hydrophilic coating (microporous or macroporous) and the other not.
- supports or even mixed surfaces, usable on both sides or only on one or the other depending on the properties mentioned, including on a surface having the double quality of being absorbent for ink. non-penetrating liquid and inking for certain others, in particular ball inks.
- the selective inking according to the desired result will be (either erasable or indelible) and therefore selective in this respect.
- the inking is carried out by simultaneously or separately incorporating the two types of ink or by the use of suitable solvents.
- inking is also carried out with inks which can be shaped dry or with water. You may not be able to use the toner in dry erase mode. The sheet is then slipped into a pocket and then reproduced again after correction or by masking the area. Indelible or erasable inking being obtained in an absolute or relative manner and this by all mechanical means (office automation and printing) or manual and this selectively and simultaneously and hot or cold by any process. In certain cases, the background coloring as well as the manual or automatic printing will be erasable and / or indelible both and only one or the other. Extrapolation of inks
- the essential properties of the inks will be:
- Lightfastness blue wool index
- diffuse light U V
- solar and dark resistance to folding, heat, humidity, and water, abrasion, etc.
- All printing resolutions are possible, as well as all colors including glitter inks, fluorescent and metallic inks.
- the essential constituents (adjuvants)
- binders in particular, opaque or transparent pigments, black, white or colored, mineral or organic, coated or uncoated by pouring (flushing), dyes for example based on aniline or its derivatives, solublcs or not and lacquered dyes.
- catalysts In the essential constituents, catalysts, siccatives, stabilizers, thickeners, gelling agents, and waxes (very good chemical resistance) will also be retained, as well as other ingredients such as gilsonite, standole, starch or dext ⁇ ne, true solvents. , latent and diluents (xylene, toluene, glycol, propanol, etc.) filler, etc. Some inks will be centrifuged.
- Photocopiers and laser printers will be able to function without the incorporation of powder (toner) and therefore without heating in this configuration, according to the same principle: the latent and then visible image being obtained on the device drum by tiny retractable needles possibly being electrodes at the places and places of each toner point and then coming to reveal a pre-inked substrate or by transfer on tape.
- Other methods according to this principle can be used in these machines (thermal paper, carbonless, dry or thermal transfer on an integral support) with printers and photocopiers not usually used for this purpose.
- These needles can also be supplied with ink, in particular by vacuum.
- a photocopier can be used in mixed use allowing the original coloring or photocopying with or without reason that the sheet is blank or printed or simultaneously in internal or external insertion.
- the interface being on the device or on a screen, the selected color button initiating printing
- the colors can be solid colors, similis, gradations, etc.
- the print heads can have these two pressure + heat functions.
- the lower layer can be revealed by pressure, this can also be used to cut the shape.
- a substrate will be personalized by positioning removable or non-removable patterns such as transfer letters, stickers or decals, drawings, symbols, photo outlines, cutouts, etc., themselves supplemented by the stencil, normographer, cliché, stamp processes. or others. They will represent drawings, letters, any patterns, various geometric shapes, such as lines, checkerboards, spheres, signs of the zodiac, etc. These can be printed at an angle of 360 ° They can represent professional symbols, logos, real or imaginary characters, and highlighting the particularities, being usable by adults and children, as well as advertising. We can also tint the whole substrate, or simply the shape and also use this principle in photocopiers with inversion of values.
- removable or non-removable patterns such as transfer letters, stickers or decals, drawings, symbols, photo outlines, cutouts, etc., themselves supplemented by the stencil, normographer, cliché, stamp processes. or others. They will represent drawings, letters, any patterns, various geometric shapes, such as lines, checkerboards, spheres, signs of the
- shade means background shade with or without patterns (on transparent or opaque substrate) on and / or under the printing layer (covering of the blanks and the printing) on all or part of the surface (solid colors) as well than actual printing.
- the color being either transparent or semi-covering, on and under the printing, or covering under the printing or at the bottom of the page in inversion of the direction of the image (under the printing) or also covering to be discovered later by scraping or washing.
- the color should not be solvent, especially on uncoated substrates as well as quickly dry, possibly accompanied by drying On may use a differently tinted substrate on either side.
- the color can be applied to all or part of the surf ace and can represent a pattern or not.
- One or more printheads or only of inking coloring the surface can work simultaneously on the surface horizontally or vertically. The speed of the printing itself is not hampered by that of the background; both of which can operate almost simultaneously or in two stages.
- printers or reprographic devices or related machines will be used. In the case where one uses printing or reprographic devices, one can use the same process as these or different processes, for example: inkjet plus laser or photocopy and ink rollers (liquid ink , wet or dry). This use of mixed machines, simple or double technology can be envisaged with other office printing processes.
- the machine will analyze the color of the substrate (if two inks, one of which is light in color) are used simultaneously when reading the document but also by inserting it into the bypass especially for external use. When the choice of printing color is possible, this choice will be offered, either automatically, or else refused (insufficient contrast).
- the other parameters that can be recognized by the machine in external insertion will be: form, thickness, hydrophilic coating. In addition, for certain applications, the adaptation of the reduction and enlargement rate will be provided. All these parameters being determined separately or jointly by marking in the support with the exception of the format.
- the coloring system of the page is different from the printing process, this can be the same in all types of devices, for example in the form of a ribbon or ink roller or removable tablets (with round section or at right angles), more or less wide and sweeping the surface over all or part of it.
- the print head will be fixed or mobile, rotating or not. If the inkjet or photocopying process is used, including on a non-hydrophilic substrate, drying may be considered.
- a solvent may also be used in addition to the ink (for example water, alcohol or solvent) in order to obtain glaze or wash effects.
- These different methods of coloring or illustrating funds can be done automatically or manually in machines, motorized or not.
- These different substrates can also be tinted by all manual means (airbrushes, aerosols, felts or pads of all sizes possibly separated from their tips or impregnation with an absorbent material of liquid or dry ink in a container for soaking rolls, rags, etc, or wet cloth).
- We can also write or draw, paint using graphic tools such as pencils, carbon and graphite (uncompressed).
- the color can be used on one or the other side on a plastic support, eliminating the phenomenon of transparency, in English, show throught and piercing, in English st ⁇ ke throught Gradation or graduation going towards medium and soft mines (on a non-hydrophilic support) for example HB or F, B to B6, EB, EE.
- HB or F medium and soft mines
- the shapes will be bevelled, conical, fine.
- the points may be interchangeable and the tank re-inked.
- These various graphic and erasing tools may be nestable, for example a dry erasable tool plus another with water or solvent and having a reservoir containing the liquid. and absorbent material on or in the tool itself. This can be adapted to all graphic tools, including highlighters.
- Erasing and cleaning means Apart from water and dry, these erasing means will advantageously be made up, alone or as a mixture, of aliphatic hydrocarbons (petroleum ethers, light and medium essences and whites spi ⁇ ts, aliphatic alcohols and aromatics, in particular glycols, esters, in particular acetates, ketones and ethers These solvents being used alone or in mixtures It is possible to envisage a strong solution with high solvent power comprising for example acetone, acetate ethyl, toluene, chlorinated solvents (for certain applications), luochlorinated fluids For the so-called moderate solution, preference will be given to aliphatic solvents, whether or not flavored, in particular light or heavy special essences in petroleum fractions or pure products mixed or not, in particular essences A, C, E, F, G, 60/95, 70/80, 80/1 10, 100/120, 100/140, 100/160, 145/160 as well as cyclohe
- a mixture of weak solvents with strong solvents will be used in very small quantity, for example, 90% E petrol plus 10% ethyl acetate or acetone 7 to 8%.
- glycol ethers and their esters ethoxyethanol and ethoxyisopropanol
- other solvents such as bleach, etc. can be used.
- the erasing product will be packaged according to use, it can be transportable in a bag or pocket. As for the contact surface with the ink, it can be changed if necessary.
- This type of printing can also be erasable, in particular by using dry erase inks, with water or with chemical solvent.
- the software will perform the printing in reverse direction of the image whether it is transfer or direct printing.
- toner compositions example styrene acrylate copolymer and the styrene and thermoplastic or saturated polyesters for the sole purpose of waterproofing the hydrophilic layer but also other resins such as polyethylene of any density, polypropylene, copolymer (EVA), terpolymer (EAA) cl (EEA MA), polystyrene , polyurethane, ionomer, as well as PV C, PV D, SBC, polyolefins and silicone elastomer.
- toner an uncoated toner dyed in the mass or naturally opaque will be retained, this type of developer being used mainly as a lower-cost background composition than conventional toner. It will be possible to emboss the plastic coating by roll. According to this same process, it will also be possible to make relief compositions.
- the transparent plastic coating can be tinted or not. In non-polychrome inking, a single pass during f usion can be achieved. For a simultaneous mixed use or not, a single drum will accept the two feeds (the developer + the tinted polymer or not) and a squeegee cleaning system, fixed or adjustable from the developer cylinder.
- Laminating is done on paper but also on coated plastic in particular, which in this case will have a second significant advantage, that of being more tear-resistant or difficult (polyester in particular) and making a relatively expensive substrate cleanable.
- a counter allowing to know the quantity of plasticizing product will be integrated.
- plastics for small areas, especially in photocopiers, this allows to fold the sheet without breaking effect.
- semi-rigid or even rigid plastics in any case rollable.
- plastics mentioned in particular all polyolefins including elastomers, as well as saturated polyesters as well as, PMM, PPE, PMP, etc.
- the essential qualities being transparency, flexibility, chemical resistance, melting at compatible temperatures.
- the advantage of the plasticization polymer recommended compared to the conventional toner being to have in addition a good resistance to chemical agents (solvent (s), base (s) and ac ⁇ de (s)) allowing the cleaning, even writing in overcoating and / or cleaning the sheet thus treated and resistance to folding
- the micronized polymer will also be provided with a polymerization catalyst, an inhibitor, a lubricant and a release agent.
- the dye may be carbon black or titanium dioxide (T1O2) in very small quantities.
- the resin may be melted without the use of. heating roller to then add a non-fusible overlay, for example polypropylene, then pressurely fix the roller according to the viscosity index (MFI).
- MFI viscosity index
- the advantage of the first system being to carry out a lamination in a single operation and very quickly. It is also possible to use a monochrome machine with one or more colors or polychrome. Of course, these machines can be used at any time for the exclusive use of reprography, it will suffice to swap the tray or the cartridge with the printing toner. We can also envision a mixed use depending on the case (interchangeable) These machines can be programmed for this purpose or not In the second case, it will be enough to stretch or place a black support on the exposure glass or to make it transit through the document feeder and if the machine is equipped with this duplicating device. Care will be taken beforehand to load the copy pass with the originals (external or internal system) with the possibility of access and in self-operated operation exclusively by the user or not.
- the choice of support can be selective by incorporating it into the machine. The choice is made on site in a complementary distributor of the photocopier or by obtaining it elsewhere but also stored in the machine itself with the possibility of choosing it according to the desired result. This selection is made by incorporating the different supports that will be positioned manually or automatically by a removable elevation process for internal loading or external copy pass. This choice will be made except the traditional paper,
- Paper one side of which will be hydrophobic in nature; for example parchment paper, waxed, plasticized, etc.
- Substrate of which one or two faces will be rubbed but nevertheless permeable may be in color on one or two sides and / or illustrated. They may have a face glued on all or part and possibly precut. They can also be transparent.
- the white parts are covered with white toner or in three passes, red, green, cyan (additive synthesis) or even transparent. This process will make the substrate non-alterable with water and cleanable (depending on the recommended solvent but with more or less convincing results.
- the support can be plastic or paper. It is also possible without adding material, by chemically or thermally melting a friction-coated substrate in which the print has passed through this overlay. Regarding laminating by photocopier, two parameters will be particularly important: speed and temperature. These two parameters can be different compared to the toner. An additional layer not melted but encrusted in the previous one can be added electrostatically or not.
- coloring whether it is plasifying or not, we can consider, mixed devices, printing more coloring or only coloring, either hot on a photosensitive drum, or cold (gel).
- varnishes Apart from the plasticization processes proper, the manual or mechanical application of varnish will be retained over the entire surface or in reserve if these are non-specific inks, and this on paper or plastic. These varnishes may be of the same nature as the inks and therefore unalterable with all solvents or with water.
- These printing or reprography machines can also be equipped with a perforation, cutting or automatic precut system (for example to cut in height at a given form), the substrate possibly having an adhesive face, and this, in the form of rolls or sheets All of these processes can be carried out in these printing machines or in ancillary devices.
- These cuts can be mono-cuts of a line, pre-cuts or multi-cuts of several lines. This operation (total or partial) can be performed sheet by sheet and as they exit from the printing system, either by bundles in the same device or in an additional device .
- Another method will consist in pre-cutting the sheet in both directions, this being kept pressed on the device then pre-cut thanks to a support provided with cutting elements (points, blades, discs, etc.).
- the cutting can also be carried out by means of a changeable movable element, cutting the sheet laterally or still manually by inserting sheets or bundles according to the principle of the cutter and by folding the cutting tool (or by any other movement) f mechanical and automatic or manual lesson.
- the four sides can be simultaneously cut or precut.
- This division corresponding to the size of the print will be configurable using software, which will allow for complex and large-size montages (poster type), maps, plans, diagrams or even reproductions of full size. ture, etc., of homogeneous sets and this, without disjoining, during the assembly, the different elements in order to preserve them a unitary impression forming an inseparable whole.
- An audible signal will be provided if the original is forgotten on the machine and a visual indicator of paper and ink reserves can be queried at any time and giving the percentage of products remaining in reserve and possibly the number of sheets that can be used at in proportion to use.
- the machine only activates if all the parameters allowing to ensure a complete cycle are met.
- a mechanical and / or manual double impression one of which will be easy to shape and the other indelible.
- the color can be produced individually, the substrate thus colored allowing writing, drawing, printing and reprography.
- To erase the substrate if these three variants are used simultaneously, when it is erased and if it is done dry (only the surface concerned will be erased), the other inks not being erased, ditto for the tools erasable with the water.
- the solvent recommended will be suitable for all other inks, including those that can be worked, with water or dry, as well as for printing not qualified as "indelible", the solvent recommended will be suitable.
- the substrate can be printed without specific materials or devices.
- the substrate of the invention can give rise to multiple applications, this substrate can thus replace paper for many of them, including wallpaper. It can be cleaned, discarded or reused by users.
- Sheets and various sheets of binders, annotations, treatments, medication, checklist, contacts, organizer, practical sheets, annotable recipes, memo, notes, flash messages, meetings, delegations, objectives , projects, ideas, collections, budget, IT, production, sales, marketing, prospects, results, studies, information, readings, hobbies, sports, shopping, banking, cars, travel, staff, jumble, results sheets, tests tests, stock cards, inventories, various lists to check or complete;
- Signs and labeling signs, boards, banners, etc.
- Precisions concerning the applications indicated with asterisq ues Schedules with removable positioning bands that can be ordered by correspondence or obtained by printer and matching the current year with the corresponding months and days. We can also protect the definitive areas with transparent stickers.
- Reusable envelopes printed or blank, in repositionable glue or not, which may have one or two openings opening with a cutting wire or dotted lines, possibly with added gluing supports, with writing, printing or label sticking, for internal use or not. The printing varnish being replaced by an embossing.
