1. Dry Offset or Litho Printing (
Sheet fed or Web)
The principle that makes this type of coating superior to
conventional spot or strip release coatings is the fact that it remains
invisible to the naked eye without creating any unsightly blemishes such as
white haze or gritty textures on your graphics. There is no need for peeling or
rubbing and scratching to liberate the aroma. A gentle touch or brush of the
wrist will release a generous amount to sample. Only odourless printing inks should be used to avoid any possible competition with the encapsulate. This is of special importance in the case of light or delicate fragrances. The application of the encapsulate must be
through the last printing station
of the press to avoid any unnecessary additional shear
and possible damage to the capsules.
The ink duct must be perfectly clean and free of any
solvents, detergents or other chemicals. No other
ingredients can be added to this type of encapsulate because of the very
delicate nature of the capsule walls. The damping fluid section of your machine
cannot be used due to the water based properties of our
products and must be turned off. The capsules tolerate heat from
dryers of up to 190°C.
This presents an
advantage to drive off residual water to speed up the curing process.
Stacking the printed stock high does not break
the capsules, they only respond to shear and not to evenly distributed pressure.

For this type of application a
special anilox roller should be created,
please contact us for details. The ink duct must be perfectly clean and free of

Like the Flexographic method, gravure printing of encapsulates generates superior coating quality and is particularly suitable for the production of drawer liners and gift-wrap etc. The application of the encapsulate must be through the last printing station of the press to avoid any unnecessary additional shear and possible damage to the capsules. For this type of application a
Cylinder with the correct engraving must be
employed, please contact us for details. The ink duct must be
perfectly clean and free of any solvents, detergents or other chemicals.
4. Silk Screen Printing (Flatbed or Rotary) This printing method can produce some very high coating weights which allow multiple sampling or release from the same area. Unlike the other methods listed above, it can be seen with the naked eye, resembling an optical effect similar to silk varnish and remains translucent to allow graphics to show through. The silk screen method becomes very useful if a specific area or a
special shape is to be applied to a part of the page. The capsules tolerate heat from
dryers of up to 190°C.
This presents an
advantage to drive off residual water to speed up the curing process.
Stacking the printed stock high does not break
the capsules, they only respond to shear and not to evenly distributed pressure.
Please contact us for specific advise for these coating methods.
6. Special encapsulates used as ingredients in specific formulations. All the above are available as ready to print products or as concentrated encapsulates for mixing with clients preferred printing / coating bases. (Please consult our advice for compatibility with your material before mixing!) |
