Labels and name plates
Labels and name plates
Self-adhesive labels and plates are produced on various types of materials such as paper, metallised paper, vinyl, aluminium, metallised polyester, polyester, polycarbonate, etc. Self-adhesive materials consist of a self-adhesive backing and a protective (siliconised) paper from which they can be easily separated for application to any type of surface, provided it is clean and smooth.
The adhesive can be:
- permanent, in which case the material, once applied, cannot be removed except by completely or partially destroying it
- removable, in this case the self-adhesive material can be removed if necessary.
Depending on their intended use, self-adhesive labels are divided into two categories:
- SELF-ADHESIVE LABELS for indoor use (paper in general)
- SELF-ADHESIVE PLATES for outdoor use (special products).
SELF-ADHESIVE LABELS are generally made of paper or metallised paper and printed using flexographic printing. They are suitable for countless applications in every industrial sector, especially where quick and economical marking is required. Supplied on rolls with a completely or partially blank surface, self-adhesive labels can also be overprinted by the customer using special printing equipment.
SELF-ADHESIVE PLATES are mainly produced in special materials and printed using screen printing. Thanks to their ease of application, wear resistance and graphic quality, they have replaced traditional metal plates.
Types of printing
Self-adhesive labels and plates can be produced using the following printing techniques.
FLEXOGRAPHY
This method is generally used to print products for internal use (usually paper); printing is done on a rotary press and the labels come in rolls.
With transparent film lamination, flexographic label printing can be protected (from petrol, solvents, grease, etc.), thus fully complying with the most stringent indelibility tests required by international specifications in force in certain industrial sectors.
The main characteristics of flexographic printing are:
-Easy machine start-up; production speed and therefore cost-effectiveness of the resulting labels: practicality, cost-effectiveness and speed of reprinting
The limitations are the maximum size of the labels (150 mm x 354 mm) and printing in no more than 4 colours.
DIGITAL PRINTING
For rapid prototyping or low-volume production, digital printing can be used. This solution avoids the need for traditional printing equipment, thereby reducing equipment costs, and offers the possibility of achieving four-colour effects with high print resolution.
SCREEN PRINTING
Screen printing is a printing technique that is particularly popular for creating plaques thanks to its exceptional durability and resistance to atmospheric agents. This method allows thicker layers of ink to be applied than other printing techniques, ensuring intense colours and greater resistance to fading caused by UV rays. In addition, the use of specific inks for screen printing allows for surfaces that are resistant to scratches, humidity and adverse weather conditions, making the plates ideal for outdoor exposure. Screen printing is therefore an excellent choice for those who want to create plates that not only maintain their aesthetic beauty over time, but are also able to withstand the challenges of the surrounding environment without compromising on quality.
HOT STAMPING
The hot stamping process involves the use of a special press that applies heat and pressure to transfer the desired design onto a surface. This method requires a metal die, usually made of brass or magnesium, which is engraved with the design to be printed. The die is heated and pressed against the substrate material, such as paper or fabric, while a sheet of coloured or metallic foil is placed between the die and the substrate. The combination of heat and pressure causes the foil to adhere to the substrate, creating a sharp and durable image. The materials used can vary depending on the desired effect; for example, matt, glossy or holographic foils can be used to further customise the final product. This process is particularly popular for its ability to give labels, packaging and promotional materials an elegant and professional look.
