Abstract
Machine to set and protect against fraudulent manipulation, modification and/or duplication copies made with toner of any document; including at least two cassettes with a polyester film, one the supplier and the other the receiver, which film is positioned by stretchers in the area between the two cassettes in which are positioned two main rollers with parallel axis with electrical resistance heaters placed very near together and between which the film passes, while the sheet to be protected runs through a guide chamber by being dragged and impelled by a roller placed where the paper enters, and the sheet of paper passes between the main rollers and in contact with the lower face of the film, which has means to set and protect the printing on the sheet.
Description
Therefore the present invention refers to a machine to set and protect printing carried out with toner against fraudulent migration, manipulation, modification and/or duplication.
Printing with laser printers, although easily modified and with an extraordinarytendency towards migration/separation, has been adopted by a multitude of companies and institutions because it offers great advantages from its connection to computers, the possibility of making graphs, high definition quality, deep black, variety of fonts, etc.
These virtues of definition quality, intensity, variety of letters, speed, versatility, small size, etc. have transformed laser printers (from small table printers to large equipment to treat and print documents) into almost essential equipment for any activity, whether commercial, industrial, financial, institutional, etc.
Their important market penetration has also placed laser printers in sectors where their printing functions raise problems of a lack of security in the printing of certain documents.
It is obvious that letters, communications, delivery notes, invoices, etc. may on some occasions be the object of a fraudulent attempt at modification or duplication, but that is not the area in which these incidents usually occur.
It is in the area of documents with important economic, professional and social influence that these attempts are usually made.
For example: Personalization of shares, Deposit Certificates, Professional Degrees, Credentials, Diplomas, Policies, Contracts, Licences, etc.
The fact is that in this area: Government, Banks, Insurance, Education, Access Control, etc., laser printers are being used to complete and personalize documents that in many cases should be protected to avoid the risks of fraudulent duplication and/or the modification or substitution of texts or images.
In almost all cases the adherence/penetration of the toner into the mass/fibre of the paper should be improved, and even specific security measures incorporated to allow the easy detection of possible attempts at fraud.
From the present situation, two basic problems can be seen:
1. The vulnerability of laser printed texts and images.
2. The relatively short life of laser prints.
2 21 622û9 The machine is based mainly on passing the sheets printed by laser between two hot rollers, that subject the sheets to a regulated pressure and a temperature of 100 to 200C, which achieves greater penetration of the toner into the paper, while at the same time incorporating on the images a picture which is either directly from the engraving made on the pressure cylinders, or by transfer from a film which holds safety measures described later.
As the laser printed sheet passes between the two rollers, the toner is re-heated and pressed strongly against the fibre of the paper. This is the moment in which the type of finish can be chosen: shiny, semi-shiny, matte or semi-matte.
This characteristic will depend on the finish treatment we have given to the cylinders (when the machine runs without film) of the finish we have given to the transfer films (when the machine runs with film). If the finish is a polished material, the face of the toner will have a polished look. If the finish is matte it will have a matte look. If it is flattened, it will be flattened, etc.
If we print with special, transferable products (selective or otherwise) a print or background on the face of the film that will make contact with the printed side of the paper, a transfer is generated which will result in a laser print with a personalised finish given by the characteristics given by the transferable film.
Aside from gains in fixing and beauty (shiny or matte) an extremely important improvement is obtained in the security of the document, since the film will have transferred to the printed sheet special security characteristics.
The machine can also work with or without the presence of a film since the rollers can be engraved with images and thus generate a special texture or drawing on laser prints.
This images can be special for each specific user by the incorporation of his emblem, logotype, etc.
The machine, in its widest extent, is made up of two rollers of film that have been previously treated with special prints defined later. The other two c~ccettes are collectors because we presume that both sides of the sheets will be "treated". If it is only necessary to treat one side, we would work with only one cacset~e/store and one c~cse~te/collector. In fact the following options are available:
1. Machine for treatment on a single side.
2. Machine for the simultaneous treatment of both sides.
Naturally the latter has the option of working on a single side.

1. Machine for treatment on a single side.
2. Machine for the simultaneous treatment of both sides.
Naturally the latter has the option of working on a single side.
As the sheets pass between the rollers, the phenomenon is created of the transfer of substances with different characteristics: photochemical, chromatic, magnetic, sensitivity to acetone, etc.
This transfer can be onto the whole sheet treated, or only on the surfaces that have previously been printed with toner.
The film on the storage rollers has been previously printed in offset or flexography, or by any other printing system able to work on a bobbin and capable of guarantying a regular deposit of fluids (inks, varnishes, etc.).
In synthesis, the treatments that the machine can carry out are basically the following:
A) Treatment without film on the whole sheet.
B) Treatment with film that transfers onto the whole surface of the treated sheet.
C) Treatment with film that transfers only onto the areas on which there is a receiving image (images printed with toner).
a) The treatment without film onto the whole surface of the sheet will, in any event, achieve greater penetration of the toner into the paper fibre. When the roller incorporates an imaged made by engraving systems with a shallow alveoli, the images engraved on the cylinder will be implanted on the surfaces of the toner.
At the same time, with this treatment without film and with an engraved cylinder, security markings can be achieved on plastic covered documents because when they are passed through the machine image engraved on the cylinder will be reproduced on the plastic surface. In this case the machine is doubly effective since the process of gluing/closing, normally used for plastic covering, can be carried out at the same time as the surface engraving treatment. It is only necessary to introduce the traditional "sandwich" and the enclosure (plastic covering) and security marking (surface engraving) with the cylinder image will be obtained.
B) The treatment with film that transfers to the whole surface of the treated sheet is called NON SELECTIVE and this means that the film is not able to distinguish where there are laser printed images and where not. Therefore the treated sheet receives the transfer on its whole surface.
NON SELECTIVE transfer can only be carried out with invisible inks since otherwise it would be impossible to correctly visualize the printed images, and may be:
Invisible luminous films with a reaction that is yellow, blue, green, etc.
Invisible films that react to the presence of solvents.
This transfer can be onto the whole sheet treated, or only on the surfaces that have previously been printed with toner.

Invisible luminous films with a reaction that is yellow, blue, green, etc.
Invisible films that react to the presence of solvents.
Mixed films that transfer both invisible luminosity and invisible reaction.
These NON SELECTIVE transfers permit:
Invisible luminous films: Check of the authenticity of the document and simple detection of any alteration or addition to the image.
Invisible films that react to solvents: Detection of any attempt at modification made with solvents (particularly acetone) that "drag" the toner while leaving practically not vestige of the operation of erasure, or erasure and substitution.
Mixed films: Combine the characteristics of the two above.
C) Treatment with a film that only transfers to laser printed images on the treated sheet is known as SELECTIVE and this means that the film is able to distinguish where there are laser printed images and where there are none. Therefore the treated sheet only receives the transfer onto the toner mass.
SELECTIVE transfer can be carried out with:
Invisible selective film perceptible under UV light. Visible selective film with UV
response. Visible selective film that cover with special colours, corporative colours, etc..
Visible selective films that cover with a magnetic response in different colours. Visible or invisible selective films that react in the presence of solvents. Visible iridescent selective films. White covering selective films. Covering selective films in black, red, blue, green, etc. Any combination of the same.
These SELECTIVE transfers allow:
Invisible selective film pe,ceptible under UV light: Check the authenticity of the document, simple detection of any alteration or addition to the image, distinguish documents by sight when the images are in a chosen colour.
Visible selective film that cover with special colours, corporative colours, etc..:
Distinguish documents on sight because they show images in a chosen colour, which may correspond to the colours of a corporation.
Visible selective films that cover with a magnetic response in different colours:
Distinguish documents on sight when they have their images in a chosen colour, which may correspond to the colours of a corporation, and check their authenticity with a simple magnetic detector of the type used to detect coins.
Visible or invisible selective films that react in the presence of solvents: Distinguish on sight any attempt to modify the text or images because a violent chromatic change occurs in the presence of solvents.
Visible iridescent selective films: Perception on sight of any attempt to photocopy in colour, due to the incapacity of colour copiers to emulate iridescence.
White covering selective films: Allow the image to disappear to the point where it is almost impossible to read and totally impossible to photocopy until the user or authorized person "prints" the image by passing it again through the machine and recovering the image by the application of a selective visible film.
Covering selective films in black, red, blue, green, etc.: Allow personalized printing of colours for presentations, reports, etc.
Any combination of the above: To allow the incorpoMtion of selected characteristics.
When passed between the two rollers, the films which have been specially printed so that they transfer in the presence of heat and pressure, give off the print onto the treated sheet. It has been explained that the removal-transfer can be SELECTIVE (only on toner images) or NON SELECTIVE (on the whole sheet treated), which generates the process explained above of pressure/heat (fixing) and security (incorporation of inks with special characteristics for identification and check by different systems).
The fusion of the toner and the incorporated substances on the film, achieved by an app,opliate propo~lion of pressure, temperature and speed, and which is perfectly controlled by the machine, allows the toner and transferred substances when fluid, to considerably increase the interaction of the Wander Walls forces, penetrate the paper fibre and, consequently, the tendency to migrate is considerably reduced.
The images formed by inks and special substances can correspond to generic designs that are difficult to reproduce (filigree, coils, etc.) or may even ,epresent trademarks, logotypes, prints, etc. specially made for the user company or institution.
In order to more easily understand not only the constitution but also the use of the rn~chine of the invention, reference is made below to a practical example of the same, this being merely enunciative and in no case limits the same, all as shown in the attached drawings, in which:

Figures 5 and 6 show in detail the manner of treating a sheet of paper (22) on one side with film (6) that has printed on its lower face invisible transferable non selective inks, invisible or otherwise (24).
Figures 7 and 8 show in detail the manner of treating a sheet of paper (22) on one side with a film (6) that has selective inks printed on its interior face, visible or otherwise (24).
Figures 9 and 10 show in detail the manner of treating a sheet of paper (22) on one side with various layers of selective inks, visible or not, covering or not (25).
In Figures 1 and 2:
The machine (1) of the invention is made up of a casing (2) preferably prismatic, with a storage tray (3) to supply sheets of paper for treatment and a receiving tray (4) to take treated sheets of paper.
Inside the machine there is an emission c~ette (5) of film (6) and a receiver cassette (7) between which the film circulates and the latter is kept stretched longitudinally by stretchers (8).
Also inside the machine, and approp~iately placed is a motor (9) whose output axis activates a double transmission (10) of belts and a gear train (11) that moves the main rollers (12), with electrical resistance, which rollers are parallel axis and near to each other, between which the film (6) passes which has means that adhere by pressure/heat/speed (the three parameters can be regulated) of the rollers to the sheet of paper to be protected, which has previously passed through a guide chamber (13).
The pass of the sheet is regulated not only by the drag rollers (14) for the entry and exist of the sheet, but also by guide rollers (15).
When it is desired to treat the sheet on both sides instead of on one only" instead of two c~settes, one supplier and one receiver, for are required placed in pairs, one pair above and the other below the circulation of the sheet inside the machine, Figure 4.
Inside the machine there is a ventilator (16) and the casing has a ventilation grill (17), a speed and temperature control panel in which an access code can be incorporated (18), a pressure regulator (19), an instruction panel (20), opening and closing tabs (21), an indicator (22) of the contents of the emission cassette and two cleaner rollers (28) for the main rollers (12).

Figures 5 and 6 show schematically the sheet of paper (22) before treatment, carrying masses of toner (23) over which the film (6) is passed where the film has on its lower face a layer of non selective inks (24) that, under the pressure and heat of the rollers (12), are transferred to the sheet of paper and cover it totally with an invisible protection (24) that comes off the film. At the same time the toner penetrates more deeply into the mass of the paper.
Figures 7 and 8 show the protection of the areas of toner (23) on the sheet of paper (22) with selective ink (24) printed on the film (6), invisible or otherwise, luminescent or not, that is transferred from the film to the mass of toner. At the same time the toner penetrates more deeply into the mass of the paper.
