Product protection with the invisible UV ink printers by REINER® marking systems

Direct printing with UV ink for invisible marking makes products and packaging counterfeit-proof and traceable

Who hasn't experimented with lemon juice as a child to write secret messages with this “invisible ink”? The classic among the secret inks works because the writing only becomes visible when the paper is heated. However, it remains visible forever afterwards, because the heat of the ink triggers a chemical reaction with the paper.

In professional everyday life, a permanently invisible label is more important than ever in order to distinguish an original product from counterfeits from the production of product piracy as preventive product protection. But purely aesthetic reasons can also speak in favour of discreetly printing markings.

The modern and simple, but also very effective “secret ink” consists of UV ink, also known as black light ink. Invisible in daylight, the printed image can only be read under illumination with special UV lamps (black light).

The mobile inkjet printers from REINER® have proven themselves reliably as industrial ink marking systems for many years. With the special UV ink, the handy marking devices combine a number of advantages in one device:

Invisible UV ink printing of many types such as invisible barcode printing, text, batch numbers, data matrix codes, graphics

• On individual parts, products, packaging, cardboard boxes

• Product marking on almost all smooth surfaces made of paper, cardboard, metal, plastic, glass, curved surfaces, coated labels

• Invisible ink printers ideal for marking small parts

• The invisible product marking can be created quickly and easily on the PC using the PCset graphic software supplied and transferred via USB or Bluetooth

UV: invisible ink for traceability in production and logistics

The marking of serial products with a batch number is an important part of quality assurance. Only this product marking allows the complete traceability of the manufacturing process, partly down to the raw material. In the event of sudden production errors, LOT or batch numbers enable the manufacturer to search for the cause.

However, this unsightly marking in the form of a data matrix code or series of numbers can disrupt the appearance of a product. Especially with small or all around visible products one would prefer to do without it. We know the perfect solution:
fluorescent colours under black light.

REINER®'s special UV ink for inkjet printers looks like a clear liquid in daylight and is invisible as an imprint on objects. Only under appropriate UV light of a black light lamp the printing in bright colour becomes visible.

UV ink as professional secret ink for discreet marking

UV ink pharmaceutical products medicine forgery-proof
Pharmaceutical products were one of the first areas of application for invisible product marking. Meanwhile you can “see” them – if you are equipped with a UV lamp – on more and more consumer goods and cosmetics, up to food packaging. In normal everyday lighting, however, even complex 2D codes such as GS1 data matrix or long barcodes remain invisible to the observer through the “secret ink”.

Especially in the document management there are a multitude of application areas in which a discrete, because invisible marking is advantageous. These can include documents with higher security requirements and copy protection requirements such as contracts, personnel files, delivery notes and much more. Because an imprint with UV ink can neither be photocopied nor photographed. A document falsification is thereby clearly made more difficult.

REINER® industrial marking ink is particularly fast drying and is therefore suitable for invisible marking and numbering on almost all smooth surfaces. Use the industrial marking ink for metal parts, paper, cardboard, plastic, curved surfaces and coated labels.

Individual items and small series with plagiarism protection by mobile direct printing

Invisible marking ink
Branded products were and are popular targets for product piracy and counterfeiting, regardless of the quantity produced. The mobile REINER jetStamp® models jetStamp® graphic 970 and REINER® 940 fully demonstrate their advantages, especially when marking individual parts and small series. Using REINER® UV invisible ink, companies and brand owners succeed in preventive product protection through invisible product marking at the touch of a button.

The invisible originality marking should only be printed by authorised persons in an inconspicuous or difficult-to-view place. This additionally increases the protection against plagiarism. As soon as there is a suspicion of product counterfeiting, lighting with the black light lamp in the right place is sufficient to immediately unmask clumsy counterfeits.

Copy protection on tickets and vouchers through invisible originality marking

In contrast to the expensive holographic copy protection on tickets, the invisible marking with UV ink offers a wide variety of application possibilities. The print image can be very individually designed with the REINER® software PCset graphic. In addition to fixed logos, DMC or texts, the jetStamp® graphic 970 model, for example, shows its strengths particularly in consecutive numbering and other unique print images.
Even during an event or when the ticket is redeemed, a lot of additional information can be printed with invisible ink, such as the date and time of entry or the entry number.
Counterfeit-proof marking is required as copy protection, especially for “monetarydocuments such as vouchers. But also for marketing reasons it can be useful to provide a voucher with an individual code which the owner does not see. In this way, the origin of the voucher (e.g. campaign or advertising partner) as well as the campaign period can be traced inconspicuously – without the customer feeling pursued.

REINER® ink marking systems: invisible numbering using black light ink

UV stamp
Direct printing of consecutive serial numbers or coded numbering on objects requires an inkjet printer that can regenerate the print image each time it is printed. With invisible UV inkjet-printer-ink, the handy, mobile marking devices from REINER® become an indispensable companion in trade and logistics.
Products in their original packaging are already marked with the manufacturer's EAN code and must also be marked with internal notes.

In order not to impair the appearance of the packaging, the invisible imprint with the transparent black light ink is ideal. For the consumer it remains hidden, but every warehouse employee can immediately check the internal marking and process the goods by lighting them with UV light.

The digital UV stamp

Forgery-proof invisible color
The REINER jetStamp® models jetStamp® graphic 970 and REINER® 940 open up completely new creative possibilities as digital inkjet printers. Above all, the same device can, for example, acknowledge goods receipt in the morning, print a batch number during the day, and discreetly print the delivery notes with UV ink in the evening. The content can be freely designed with the powerful REINER® software PCset graphic.

Via the integrated Bluetooth and USB interface, the print image can even be dynamically fed via software from external sources such as ERP or merchandise management – individually for each individual print.
