Multi-purpose, UV drying screen printing ink
Applications
UVSCO01 series is versatile UV curable screen in formulated for printing on paper, cardboard, vinyl, hard PVC, polystyrene, polycarbonate and many other kinds of plastic.
Printing on treated polypropylene and PET when combined with Hardener UV0001.
Printing on PMMA (see Remarks).
Label Printing
The UVEPLAST inks are ideally suited for flat screen printing of labels on treated or coated polyethylene and polypropylene, coated paper and metallized polyester.
The inks perform well in combination with letterpress, flexo, hot stamping and thermal transfer printing.
Attention: Because of the enormous variety of substrates it is highly recommended to undertake proofing trials before commencing production, to insure the ink meets production and end user requirements.
Recommended Mesh
Use a mesh between P 140 T and P 180 T.
We recommend to print Phosphorescent ink with mesh P 79 T or more coarse-fibred.
Dilution
These inks are supplied at press ready viscosity.
If necessary, they can be diluted using about 10% reducer UV0018.
In cases where dilution could result in a reduced drying speed, we recommend to add UV0012 for coloured inks and UV0013 for white inks.
Drying
All inks have been tested at 30-40 m/min under a 120 Watt/cm lamp.
The adhesion properties of UVSC01 inks are very much influenced by the in depth polymerization of the ink film and this by the opacity and thickness of the ink layer.
These factors are in turn determined by the mesh, the print image, the hardness and the angle of the squeegee.
The UVEPLAST inks have been developed for screens P 150 S and finer.
If a thicker ink layer is required a mesh P 120 T could be used but this might, depending on the printing speed, require the addition of ± 3% photoinitiator UV0012 or UV0013.
Photoinitiator UV0013 is recommended for white and pastel colours, photoinitiator UV0012 for all other colours.
Cleaning the Mesh
The mesh should be cleaned with the all-round WASHING AGENT UV0009.
UVEPLAST UVSC01 inks give a beautiful glossy finish with a high opacity.
Once they are fully cured UVSC01-series has excellent solvent resistance.
UVSC01 inks have almost unlimited mesh stability and extremely fine resolution, making it possible to print extremely fine details.
It’s virtually impossible to over cure these inks, giving perfect intercoat adhesion even between multiple ink layers.
Stencils should ideally be made with a high quality, solvent resistant emulsion.
One litre of ink covers between 60 and 100 square metres, depending on the surface and mesh used and the image being printed.
The inks will last for twelve months if kept in a cool, dark place.
Good lightfastness and weather resistance.
