Extensive DK Label Tests
Like all direct thermal labels, Brother DK paper, 2-colour paper and film labels are not designed for durable, permanent
labelling. However, as these tests show, Brother DK paper, 2-colour paper and film labels are an excellent solution for
short-term labelling. If durable, long term labelling is required then Brother TZe tapes should be used.
Abrasion Resistance Test
Brother DK film material withstands moderate* abrasion without affecting
the legibility of the text.
Brother DK paper labels protect against accidental marks and scratches, due to a
special coating applied to the surface of the paper labels.
The Abrasion Test Procedure
A 1kg sanding device was passed over Brother DK film, paper and 2-colour paper
labels. After 50 return passes the DK film labels were completely unaffected.
The DK paper and 2-colour paper labels’ print quality stayed completely
unaffected, even though slight scratches appeared on the paper itself.

Temperature Resistance Test
Brother DK labels can be used in a wide range of temperatures, from freezing cold
to hot environments.
The Temperature Test Procedure
Brother DK film, paper and 2-colour paper labels were attached to stainless steel,
heated and cooled.
The Temperature Test Results
The results showed that DK film labels were unaffected throughout the
temperature test, whether placed in -80°C or in +80°C*. The DK paper labels
were unaffected at temperatures ranging from -80°C to +60°C, but showed
slight discolouration at +80°C.
The DK 2-colour paper labels were unaffected at temperatures ranging from
-80°C to 25°C, but showed slight discolouration at +60°C and the red colour
could not be distinguished at +80°C.

Indoor Fade Resistance Test
Brother DK film, paper and 2-colour paper labels are ideal for indoor
usage.
The Indoor Fade Test Procedure
Brother DK film, paper and 2-colour paper labels were attached to coated metal
plates and placed inside a fade-inducing chamber at +24±2°C with 60%±5%
humidity. They were left for a period of 52 hours.
In addition, DK labels were placed in a natural office environment for one year and
inspected for any obvious changes*.
Indoor Fade Resistance Test Results
Both the Brother DK film, paper and 2-colour paper labels remained completely
legible, as shown below.

*Different environmental conditions will have varying effects on the printed DK labels, and as such Brother cannot guarantee that labels placed
in another environment other than those as tested will have the same results as shown.

Outdoor Fade Resistance Test
Although DK labels should not be used for long periods of time
outdoors, tests show the yellow DK film material is most suited
for temporary outdoor labelling applications.
The Outdoor Fade Resistance Test Procedure
Brother DK film labels were attached to coated metal plates and placed inside a
fade-inducing chamber and left for a maximum period of 100 hours. In addition,
labels were placed in a natural outdoor environment and inspected for any obvious
changes*.
Outdoor Fade Resistance Test Results
Test results show that DK labels are not ideally suited for use outdoors for periods
over one month. For these applications, we recommend the use of Brother TZe
laminated labels.

Water and Chemical Resistance Test
Brother DK film, paper and 2-colour paper labels were tested for their legibility in various chemicals and water.
Water and chemical resistance tests were conducted in two stages:
Stage 1: The water and chemical submersion test
Stage 2: The water and chemical abrasion test
Stage 1: Water and Chemical Submersion Test Procedure
To test Brother DK film, paper and 2-colour paper labels against the effects of water and chemicals, the labels were attached
to glass slides and immersed in a variety of liquids for 2 hours.

Solution

The labels most resistant to submersion in the chemicals tested were the DK film labels. However, in general none of the
labels should be submerged in highly volatile chemicals, such as acetone and ethyl acetate. In general, we recommend the
use of durable TZe laminated labels should labels be subjected to chemicals.

Stage 2: Water and Chemical Abrasion Test Procedure
Brother DK film, paper and 2-colour paper labels were affixed to several glass plates, and a 500g weight with a chemical and
solvent infused cloth was passed over each label 40 times (20 return passes).
Water and Chemical Abrasion Test Results
Brother DK film labels remained unaffected when rubbed with a variety of chemicals and water. Should any chemicals be
accidentally spilt onto the DK film labels, wiping them dry should help avoid any damage. The DK paper and 2-colour paper
labels showed some discolouration when tested with several of the chemicals, however, the text itself remained legible. If
spillages of water, Sodium Hydroxide, or Hydrochloric Acid do occur, do not wipe the label, but simply let it dry.

Strong Adhesion Test
Brother DK paper and film labels are both supplied with a strong adhesive
to ensure that they remain stuck to most common surfaces.
Strong Adhesion Test Results
The table shows that an adhesive strength of at least 11 Newtons was maintained
with most materials, indicating sufficient adhesive strength against most common
materials.

Strong Adhesion Test Procedure
To test the adhesive strength of Brother DK film and paper labels, 25mm wide
labels were affixed to a variety of surfaces and left for 30 minutes.
The adhesive strength was tested by removing the label at an angle of 180
degrees. This testing method complies with Japanese Standard JIS Z0237 testing
for adhesive tape.

Brother Genuine Supplies
Brother Original Supplies offer peace of mind and quality guaranteed.
Brother Genuine Supplies work in perfect harmony with Brother printers.
Designed, manufactured and tested in controlled environments by the same team
of engineers as Brother hardware. Providing you with the best possible results for
your business and protection of your print investment.
1. A random sample of tape types were selected and used to perform these tests. Accordingly, results may have differed slightly, depending on the type of tape used.
2. The actual test results were acquired under specific conditions configured by Brother, with the sole aim of providing information contained within this booklet. Brother does not
guarantee the strength, safety or accuracy of numerical data.
3. Since tape adherence performance is affected by the material the tape is attached to, the material’s surface condition, whether it is greasy, dusty, rough or curved, and the
environmental conditions, the customer should confirm adherence performance under actual usage conditions after purchasing the tape required, and use the product under their
own responsibility.
4. Brother accepts no responsibility for injuries or lost earnings resulting from application of the information contained in this document.
