Product Type: Varnish

Labeltech OP Varnish

Labeltech is the new generation water based inks formulated to be user friendly on the printing press. These inks are characterised by their ability to provide high quality prints with minimal on press adjustments.

The inks are of a neutral ph that translates into low odour around the press. The major application is for Flexo and Gravure overprinting to give high gloss and better resistances to moisture, oil, climate etc. on a number of different substrates. Labeltech OP Varnish has the capabilities of printing on both porous as well as thermoplastic substrates and with minor adjustments in the formulation. The ink will maintain adhesion and film integrity. Labeltech can be used on both fast and slower machines on a number of stocks. This ink can be used with or without bladed inking systems.

Properties

  • High scuff resistance
  • Rapid drying for high speed printing
  • Good dry and wet rub resistance
  • Good Cobb index for paper and board
  • Very good press stability
  • Easy clean up
  • Neutral ph/no adjustments on machine
  • High gloss
  • Good mileage
  • Excellent resolubility
  • Good slip properties

Application

Ink viscosity should be adjusted to the press conditions dependant upon job design, substrates and print speed.

Wash up

Water is normally used just after stopping the press. However, if the varnish has been allowed to dry on the
anilox or stereo, an aqueous solution and amine may be necessary to fully remove the dried Varnish.

Caution

Labeltech OP Varnish is independent of ph and therefore it is not recommended to blend with standard varnishes as this could cause stability related problems.

BCF

These inks have been formulated in accordance with the recommendation of the British Coatings Federation.

Waste disposal

Care should be exercised in the disposal of printing ink waste. This should be carried out in accordance with good industrial practice observing all the appropriate regulations including the relevant guideline notes to the Environment Conservation Act and Regulations (73/1989).

Hi-Slip Label Varnish

The Hi-Slip Label Varnish was developed to be printed over various ink systems on labels to enhance the slip and anti-blocking properties. Due to the variety of substrates, applications and specification requirements, it is essential that the requirements be discussed with our technical services department.

Properties

  • Good Gloss
  • Heat resistance 140°C -150°C, which is suitable for many seal applications

Substrates

  • Treated polypropylene films
  • Treated polyethylene
  • Primed metallised films
  • Washed foils
  • Paper

It is advisable to have films treated to a minimum of 38 dynes/cm to achieve good adhesion.

Reduction

SLOW: Dowanol
NORMAL: Meths
FAST: 1:2 Meths: Ethyl Acetate

With the use of any slow solvents, care should be taken to avoid solvent retention as even small percentages of “clean” solvents can  cause taint and odour.

General

The main uses of water-based inks have been in the paper sack and carton field where highly absorbent papers or liners are used.

The system has been modified for less absorbent and more flexible substrates such as Polywoven Polyprop and Polyethylene.

The print becomes satisfactorily water resistant shortly after printing. The non-hazardous properties of the product are a major advantage.

Wash up

Water is normally used just after stopping the press. However, if the varnish has been allowed to dry on the anilox, stereo or cylinder, an aqueous solution of solvent + amine may be necessary to fully remove the dried on ink.

Caution

Aquasharp Inks are independent of ph and therefore it is not recommended to blend with your regular inks as this could cause stability related problems.
