ERB INK SERIES

TECHNICAL INFORMATION

ERB waterbased inks are formulated for flexo printing of carton board substrates which will be subsequently overcoated with polyethene for production of liquid packaging cartons.

SUBSTRATES:

ERB inks may be used for printing of uncoated and claycoated carton board for production of liquid packaging cartons.

PROPERTIES:

Good Printability Low foaming potential Low odour High colour strength at low viscosity Water reducible Accepts polythene extrusion coating Colours have reasonable degree of light fastness but may not withstand extended exposure to sunlight. If improved lightfastness is required this should be specified at time of order.

PRESS CONDITION:

ERB inks can be printed at a range of printing speeds up to 400 m/min. However, being waterbased products care must be taken to ensure adequate drying at these speeds and that ink pumping and circulation systems do not cause foaming by excessive agitation of the ink. Rubber or photopolymer plates may be used Mild steel rollers should not be used as these are liable to rust.

REDUCERS:

Reduce with water only to printing viscosity.

WASH UP:

Water is normally used. However, if inks have been allowed to dry on the rollers or stereos, glycol ethers or mild alkali solution may be necessary to fully remove dried ink. To avoid "drying in", inking and anilox rollers should be kept turning at all times and stereos should be washed with water on press stoppages.

STORAGE:

Being waterbased ERB inks are not considered highly inflammable.

ERB inks should not be allowed to freeze.

Note:

This information has been carefully compiled from experience gained in field conditions and detailed laboratory testing. However, the product's performance and it's suitability for the customer's purchase depend on the particular conditions of use and the material being printed. We recommend that customers satisfy themselves that each product meets their requirements in all respects before commencing a print run. Since we cannot anticipate or control the conditions under which our products are used, it is not possible to guarantee their performance. We would point out that the information provided here is only a recommendation, and may need to be altered to suit the conditions and efficiency of the equipment employed.
