STAR BRAND SHEETFED OFFSET INKS

TECHNICAL INFORMATION

SUBSTRATES:

Printability is good on a wide range of coated and uncoated paper and board (not recommended for uncoated paper less than 60 grams / sq.m. The inks are not designed for use on non-absorbent substrates such as metallized paper and plastics.

PRESS PERFORMANCE:

STAR BRAND inks give trouble free printing with simple tap water & wide range of founts. The inks do not have over night duct stability, however these inks have duct stability of about 5 - 8 hours (depends on environmental conditions).

SETTING AND STACK PERFORMANCE:

STAR BRAND inks are not as fast setting inks as our PRIMANOVA and PRISM inks. To achieve good stack performance, stack height should be as minimum as possible.

DRYING:

Drying is quick and effective with or without IR assistance. If this is used we would suggest keeping stack temperatures below 40 °C, to avoid re-softening of the inks.

RUB RESISTANCE:

STAR BRAND inks will give satisfactory scuff resistance on a wide range of substrates. However, some materials are very aggressive, and where no protective varnish is to be used, the printer should be satisfied that abrasion resistance will be adequate, or obtain advice from Coates Lorilleux.

VARNISHING:

Spirit and water based varnishing is possible. However, attention should be given to the resistance properties of the inks used, and the varnishing done under controlled conditions. Work should be thoroughly aired before spirit/water base varnishing. Specific requirements should be given to Coates Lorilleux when ordering.

LIGHTFASTNESS:

STAR BRAND inks will have a reasonable degree of light fastness, but some colors may not withstand prolonged exposure to sunlight. In particular, tints will have lower light fastness than the equivalent full strength color. If lightfast inks are required this should be specified at time of ordering.

OTHER RESISTANCE PROPERTIES:

Pigments used are not necessarily resistant to all post printing conditions that may be encountered. Thus, if specific properties are required, such as soap resistance; this should be specified at time of order. It should be noted that the resistance properties of blends might differ from those of the component colors.

FOUNT SOLUTION:

Damper settings should be kept at the minimum for clean printing. Excessive or very acidic fount can retard inks drying, giving poor scuff resistance or set off. The fount and press temperature should also be controlled to avoid over emulsification.

BLANKETS & ROLLERS:

Any oil resistant blanket and synthetic rubber or polyurethane rollers are suitable for use with Star Brand inks.

INK ADJUSTMENT:

STAR BRAND inks are supplied press ready. However, if consistency or tack is to be adjusted; small amounts of suitable reducers can be added.

Additions should not exceed 5% of the ink.

WASH UP:

White petrol can be used, although specialized cleaners may prolong the life of blankets and rollers. Although under normal conditions the inks will be overnight duct stable, we do recommend daily cleaning of rollers and blankets.

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.
