Printing Inks Solvent Based

for rotogravure / flexo - detailed information

Quality	Water-covering capacity	Particle size distribution			Apparent density	Optical characteristics
	(cm²/g)	D10 (µm)	D50(µm)	D90(µm)	(g/cm³)
9000	8000	3	9	20	0,8	Fine/brilliant
13000	12000	2	7	16	0,8	Very fine/high coverage

Bronze:	30-35%
Solvent:	60-30%
Binder:	10-35%

How to use

1/ Mix a first part of the solvent used in your formulation with the recommended bronze grade.
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 (ie 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.

for Offset printing - detailed information

Quality	Water-covering capacity	Particle size distribution			Apparent density	Optical characteristics
	(cm²/g)	D10 (µm)	D50 (µm)	D90 (µm)	(g/cm³)
Ultra Fine FT	14000	1	3	7	0,8	Very high coverage

Bronze: 50%
Binder: 50%
Mix gradually pigment to binder until pigment and binder are homogeneously dispersed.

NOTE:

Some additives may be required for better printing results.
