Durability. Presentation quality. Production reliability.

The PrintoLUX® process has given the labelling technology industry an innovative boost.
There are other convincing factors in addition to the significantly increased customer benefit in terms of cost-effectiveness.

Simply good!

Quality & Durability with the PrintoLUX® process.

The PrintoLUX® process has set new standards for the production of industrially used labels. Compared to conventional processes, the process achieves a high degree of persuasiveness.
  • The special presentation quality and high durability that can be achieved with PrintoLUX® form the supporting columns.
  • User-friendly operability and great economy are added. By using PrintoLUX®, savings of over 40 percent are not uncommon.
  • Quality and durability high, prices down: PrintoLUX® customers take advantage of this double progress.

Durability

Independent test laboratories regularly confirm the extraordinarily high resistance of the labels produced with PrintoLUX® to temperature, chemical substances and physical damage.
Acetone, many oils, greases, superheated steam and dry ice cleaning do not affect the pressure.
The core of the process that justifies this high level of resistance: The adhesion of the ink to the carrier material does not occur physically (cohesion), but is effected by a chemical bond (adhesion) between ink and carrier material.

Applied test methods for PrintoLUX® certified materials

  • Wipe and abrasion test
  • Cross-cut test
  • UV resistance test
  • Weathering test
  • Salt spray test

Presentation quality

The patented process delivers a high-precision, high-contrast print image in photo-realistic display quality. This is especially true for the display of codes and the printing of very small formats.

The PrintoLUX® process works with water-based and environmentally friendly inks and delivers a print image in photorealistic display quality. With hp inks (hp stands for "higher pigmented") all colour tones defined by RAL/Pantone can be simulated.

As a great advantage, our customers also experience the precision of the representations on small sign formats as a result of the increasing miniaturisation of signs. 
Thus, the marking of DataMatrix codes in the format 2.5 mm x 2.5 mm is not unusual for us. It is in demand from some industrial customers and allows the code to be easily removed with a smartphone.

Production reliability

For PrintoLUX, one of the primary corporate objectives is to take up the impulses and requirements of the market in the continuous further development of the process.

All components of the process have undergone extensive testing before being used. Our marking systems in particular embody the performance and reliability of "Made in Germany".

Incoming goods inspection at PrintoLUX

Being thorough and careful are amongst the performance characteristics that have turned "Made in Germany" into what it signifies today. We feel linked to this tradition and thus systematically check all our components’ quality, functional reliability and potential for optimisation. We particularly pay close attention to the goods inwards inspection at PrintoLUX in addition to our comprehensive material testing.

1

Quality control

We carry out quality assurance on all PrintoLUX®-certified materials prior to storing and/or processing them to make sure they meet our labelling process’ stringent demands

  1. As part of the goods inwards inspection we cut formats of 120 x 160 mm from each batch.
  2. We clean four of these sheets with PLX cleaner and PLX cleaning cloths.
  3. After the PLX cleaner has dried we apply PLX pre-treatment using PLX pre-treatment cloths.
  4. After the pre-treatment fluid has dried we print the test pattern onto these four formats before they undergo thermosetting.
2

Adhesion

Directly after test patterns have cooled down they undergo a cross-cut test as per DIN EN ISO 2409:2007 to verify the print’s adhesion. For this purpose, we cut a tight grid into the surface and brush it off. Then we apply Tesa® adhesive tape 4651 to the grid and quickly remove it again after having left it to settle for five minutes. The best possible result: cut edges are smooth and there is no peeling. Materials only meet our quality guidelines if samples achieve this category GT 0 result.

3

Scratch resistance

We then put materials through a scratch resistance test using a pencil with a degree of hardness of 6. As part of this test,
printed test areas are processed a minimum of six times from left to right using a sharpened pencil and a pressure of
10 Newton (10 kg*m/s²) at an angle of 90 degrees. After this test no ink must have peeled off to meet quality standards.

4

Chemicals

A comprehensive test series analysing the resistance to a series of chemicals represents the last step of goods inwards inspections. In this process, isopropanol, acetone, cellulose thinner, concentrated soda solution and vinegar essence (25%) are used. The test surface is processed with the relevant chemical as part of 50 abrasive cycles at an abrasive pressure of
20 Newton (20 kg*m/s²) from left to right. Materials pass the goods inwards inspection if there are no visual changes of the printed colours after the tests.

5

Approval

After having successfully completed tests our quality assurance staff approves the materials. Each approved batch is assigned a batch card number. Test specimen and retention samples are archived with this number. The batch card number has also been included on the delivery slips of the panel material and sheet boxes supplied to retail.
