Technical Information

Correx screen inks are a range of inks designed for printing onto Fluted Polyolefines such as Correx. They may be air dried or jet dried to a gloss weather resistant film, with good lightfastness. In general these inks are of good opacity reducing the tendency to show variations in colour due to the corrugations on the material. Correx inks have excellent screen stability and printing characteristics, with low odour making them pleasant to use.

Printing All types of stencils are suitable except Stenplex Amber and lacquer adhering films. All grades of monofilament mesh are suitable, however, for optimum gloss and outdoor durability, it is recommended that meshes no finer than a 90T are used. Correx inks are suitable for manual and semi-automatic printing.
Thinners 10-15% thinning for normal use, for very warm shop conditions CorrexRetarder is available. Using a 90T mesh a coverage of approximately 45-55 Sq m/kg can be expected.

Drying Air dry in approximately 40 minutes depending on ambient temperature and mesh used, overprints will take longer. Full adhesion is not developed until 1-2 hours after printing. When heat drying, it is recommended that the temperature should not exceed 60°C as sheet distortion could occur.
Colours A full range of colours including process colours, metallics and fluorescents. The lightfastness of fluorescent colours is directly dependant on the film thickness of the ink. With a heavy ink deposit outdoor life should normally be at least 3 months in temperate climates.
Uses Fluted Polyolefine sheet, such as Correx, Huntsman Fluted and Corriboard. These materials are used for estate agents boards, signs, displays and general point of sale works. Other forms of treated polypropylene may also be printed.
Polyolefine is a plastic with a variable ink receptive surface.It is essential to pretest the adhesion of the ink each time before a full print run is started. This is particularly important with old stock. The treatment given to these materials to make them ink receptive is not permanent. Care should also be taken in handling sheets, as finger marks can impair adhesion.
