PRINTING IN GRAPHIC ARTS
Heat stamping is done by pressure and temperature. This process is performed by contacting the stamping film with the substrate. The stamping device has an engraving installed that contains the design, motif or brand we want to make. This engraving is hot, and when pressed against the film and the substrate, the film is anchored on the substrate, leaving on it, the motif or mark that contains the engraving. Depending on the type of device / machine to be used, we can offer different formulations (qualities) of heat stamping film. We have formulations for flat, rotary, semi-rotary stamping machines, etc.
In addition to the stamping system to be used, we will also have to take into account two determining factors when choosing the appropriate film quality:
- Type of brand to make: background, mass, profile, combination of them.
- Type of substrate to be printed: rough, smooth, porous, coated or uncoated paper, laminated (OPP / PET / PP, etc.)
Depending on the hue, we can find different types of finishes:
- Metallized films
- Matte movies (pigments)
hot stamping solutions
Hot stamping is the solution for surface decoration in the graphic industry. No other transfer finish meets the most stringent requirements, such as handling rough surfaces and tactile designs with exceptional gloss and durability.
With our hot stamping solutions, you get almost unlimited design possibilities, a wide selection of colors and touch effects with maximum customer appeal. Thanks to our extensive experience, we rely on our transfer technology, which makes refining a huge range of substrates accurate, durable and possible with high quality. Blank or printed cardboard and papers, and even laminated or other difficult surfaces can be decorated very cheaply and more easily with our new hot stamping qualities.

Cold stamping is an increasingly used alternative to heat stamping. The engraving is replaced by a polymer that will contain the image to be printed. This polymer is impregnated with an adhesive, which in turn is transmitted to the substrate. Once the substrate is impregnated with the adhesive, it comes into contact with the printing film, and is transferred onto the substrate, leaving the motif to be stamped on the transfer.
All cold stamping films are re-printable, that is, we can apply inks or varnishes on them getting a good anchoring of them.
These cold tapes can be applied in both Flexo and offset printing bodies and in both narrow-band and sheet-format rolls.
We have two specific adhesives to perform the cold stamping process, when it is done through a Flebography body:
- Brilor FUV 02, standard quality, good speed and profiling which is the one used to transfer the film on the substrate.
- Brilor FUV 01, Premium quality, is defined as a high density adhesive that allows us to work faster and give better profiling to the film.
There are a smaller number of shades than in Hot Stamping because the great thickness of these tapes is in glitter gold and glitter silver, although there are also matt and direct colors of cold films but in less variety.
Inside the cold stamping we will find the UV Casting technology, this process is applied from the same cold stamping module. This product that gives a holographic finish to the label. It will always be the last process we will carry out, because once applied it does not allow any further process. It is applied in the same way as cold stamping but instead of using adhesive, we will use UV varnish. The process will be the same as if we applied a cold film, which will allow us to make partial or total finishes.
This product is available in the same holographic patterns that we find in hot or cold stamping, so the finishes are also the same.
This product can be very economical since it allows its reuse between 5 and 10 times. This is possible because ten holographic structures that are transferred one by one on the substrate are housed in the polyester that acts as a carrier. In this way, the rewind roll is reused until the holographic structure transfer loses intensity.
Fast, glossy finish with cold transfer
If you need premium large-format metallic finishes and want your customers to enjoy the best results while relying on an efficient and stable standard process, KURZ’s cold transfer innovations create metallizations directly in the printing process, with high efficiency, captivating beauty and fine filigree patterns.

As technologies and forms of printing progress daily, it is more frequent every day to find companies that use digital printing equipment and that at the end of the line has a varnish application device using inkjet or toner that subsequently when in contact with stamping films, make the decorative package of the stamping tape adhere on the Varnish.
In the same way, we can find this same type of stamping but where the black toner ink acts as an adhesive and the decorative package is transferred onto the toner.
If you have one of these devices, we also have the appropriate tapes for this type of finishes / technology.
VOLUMETRIC STAMPING – HEAT MOULDING
More and more frequently we find embossed prints that are not made with conventional clichés.
These embossing prints are made by using a screen printing body in which, by means of a serigraphic adhesive / varnish applied by screen printing, we get the relief, and then in a stamping body, apply the decorative package on it.
For this technology it is required to have a screen printing body and then a stamping body.
We have all the materials / components at your disposal for this type of stamping.
One of our business lines that has had the most growth in recent years is the one in charge of developing new products for brand / product protection. The main objective of these protection tools is to defend companies / organizations against the aggressions they receive from the environment / market.
Today, given the great threat posed by counterfeit products: parallel markets, imitations, unlicensed products, etc. For companies and institutions, they are obliged to protect their products through security elements (OVD-holograms) that prevent counterfeiters’ networks from introducing products to the market through totally illegal means, and in the event that they managed to introduce them, have differentiating elements so that our clients have the basis of judgment to recognize our products.
Our accumulated experience in these 60 years of experience, together with that of our partners, Leonhard Kurz-OVD Kinegram, has facilitated the possibility of working with companies, institutions and organizations around the world, such as the C.R. of the D.O. Rioja, Ribera del Duero, Idiazabal; merchandising of companies such as La Martina, Lamborghini, Playstation; organizations such as: UEFA, Metropolitan Transport Associations (ATM Barcelona); governments of the 5 continents, guaranteeing the security of their currency (Euro, English Pound …) and official documents (ID, passport, driving license).
When we refer to holograms, we must keep in mind that it is a dual element. On the one hand, it serves as a barrier to protect us from copies in parallel markets (security), and on the other hand it is a great marketing tool that enriches the perception of the product transmitted to our user audience. Different studies show that products containing holograms convey originality, quality, and confidence to the end user.
Another property that we can find in the latest generation holograms is traceability.
Since this year we can offer you a hologram that includes a 2D diffractive QR code, so that in addition to security, image, we can offer all the benefits of a QR code in relation to the track & trace of our product.
The support on which we can offer these products varies depending on the final application, being able to offer it in hot stamping foil, cold foil, and in self-adhesive label (sticker).
When the hologram is presented in a self-adhesive label format, it includes the evidence alteration system. This system means that once the label is hooked, if we try to peel it, it is disabled for later use (See photo).
Trustseal self-adhesive “Arqué Padlock”
It is also available in different finishes, metallic silver, gold, transparent, copper. In relation to the design we could offer images with registration and images in continuous (indiana).

CODING AND MARKING FILMS
These films are hot-stamping pigment tapes for labeling on both flexible and rigid substrates.
Indicated for multiple uses: marking and coding of lot numbers, expiration dates, graduations.
They can be used in both manual, automatic, semi-automatic and pneumatic markers.
The most common fields of application are:
- Plastics of the medical sector
- Plastic cards
Availability of black ribbons and different colors: red, white, blue, green.
STAMPING IN PLASTICS
Within the stamping of rigid plastics we can talk about two large groups:
- Group 1 – ABS, ASA, ABS / PC, PC, PMMA
- Group 2 – PP, PE, Acetate
Depending on the plastic resin we are going to decorate, we can offer different metallic finishes, pigments, chrome etc.
Rigid plastics can be decorated using 2 types of techniques:
VERTICAL STAMPING (UP & DOWN)
This process decorates the pieces together through a pneumatic and / or hydropneumatic vertical press heated by the application of pressure and temperature. It allows decorating flat surfaces or cylindrical surfaces by rotating the piece under the head.
The most common applications are:
This process decorates the pieces continuously using a heated silicone wheel, coupled to a pneumatic vertical press, applying pressure and temperature. It allows to decorate flat, circular, cylindrical surfaces.
The most common applications are:
EXTRUSION / PROFILE
Process of decorating pieces in continuous, in the same extrusion line or outside it, by using heated and profiled silicone wheels, which apply pressure and temperature on the area to be decorated. It is common to use wheels in series to decorate a greater number of surfaces / faces of the profile. Main industries: moldings, aluminum carpentry, profiles.
IMD – INS: IN-MOLD DECORATION – INSERT MOULDING
IMD is a technique for decorating flat plastic surfaces inside the mold. The film sheet is placed between the two parts of the mold, specially designed for this technology, to be transferred to the plastic during the injection process. This process allows continuous decoration or registration.
- Automotive sector
The INS is a technique of decorating plastic parts that is characterized by its high flexibility in terms of geometry, also called Insert Molding.
The decoration (embossing tape) is supplied in rolls of ABS of 500 or 750 microns, so that they are subsequently thermoformed and create the insert. This insert will be placed later in the mold and will serve as an external decoration of the piece.
