DH SERIES INKS

TECHNICAL INFORMATION

DH series are highly transparent inks formulated for flexo and gravure surface printing onto a range of NC coated foils, papers and boards.

SUBSTRATES:

DH series inks have good adhesion, printability and transparency on a range of NC coated foils. They are also suitable for printing on coated and uncoated paper and board. They are not normally suitable for printing onto films.

PROPERTIES:

DH series inks have good scuff and abrasion resistance on a range of substrates. They will give good colour strength at normal printing viscosities. DH series inks are heat resistant from 120°C to 170°C and suitable for printing in heat seal areas. Specific requirements should be advised to Coates Lorilleux. Colours will have a reasonable degree of light fastness, but may not withstand prolonged exposure to sunlight. Dye based inks are not generally regarded as having high lightfastness. For applications requiring this property pigment based inks of appropriate fastness are normally required. Requirments should be specified at time of order. DH series inks are not suitable for lamination.

PRESS CONDITIONS:

DH series inks can be printed at most printing speeds without problem. Where fast print speeds are used, it is recommended that efficient drying units are utilised. High rewind tensions are not recommended.

REDUCERS:

The recommended reducers for DH series inks are: Normal: Ethanol/Ethyl acetate. Slow: N-propanol/N-propyl acetate. These can mixed in the ratios of 4:1 to 3:1 alcohol to ester for flexo printing, or 2:1 for rotogravure printing. Retarder : Maximum 5% glycol ether. Isopropyl alcohol can be used instead of ethanol but this may be detrimental to the gravure printability.

WASH UP:

Alcohol ester blends.

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.
