Gravure/flexo printing

Metallic pigments for Gravure/flexo printing.

Metallic pigments are widely used in gravure/flexo printing processes for its special effects. A touch of gold or
silver on decorative products such as wallpaper covering, on food label or any other packaging will make any
products stand out. Metallic effects of the highest quality are available for these processes.

User recommendations for gravure/flexo printing

conventional systems

Indicative formulations

Aluminium: 20%GoldBronze/Copper: 30%
Binder: 80%Binder: 70%

How to Formulate?

  1. Make first a pre-dispersion with the recommended aluminium /Gold bronze /Copper pigment .

  2. The obtained liquid dispersion is then to be mixed gradually to the binder using a slow rotation mixer (50rpm).

  3. Add remainder quantity of solvent and eventually other additives.

Notes

Use binders with a low degree of acidity (neutral) to improve the stability of the ink.
Aggressive binders (i.e. nitrocellulose) can provoke a reaction of the metallic pigment in the binder.
When using aggressive binders, keep the quantity of binder to a minimum and increase the solvent loading.
Using a high rotation mixer may break the particles and as a result lower the shine and metallic effect.

water based systems.  Aquastab grades are recommended for one pack
water based systems with shelve life requirements

Gold Bronze / Copper:

Aquastab Grade: 35%

Water: 10%

Binders: 55%

Aluminium: 

Aquastab Grade: 20%

Water: 10%

Binders: 70%

How to Formulate?

1. Add a small quantity of water to Aquastab Gold bronze- /Copper-/Aluminium paste and mix until pre-dispersion is homogeneous.
2. Add predispersion to binder using a slow rotation mixer (50RPM).
3. Add remainder quantity of water and eventually other pre-dissolved additives.

NOTE:

Use binders and additives of a neutral PH for optimal stability results.

Metallic effect:

Splendor : Homogeneous metallic effect with the highest opacity , still with good luster.
