HOW TO USE

1. Ink is supplied in ready-to-use condition. Stir well before use.
2. Add 41-00 REDUCER up to 10%, if necessary.
3. Standard curing conditions: (These conditions change depending on the substrate.)
   One metal halide lamp 120W/cm, Distance from focus : 10cm
   Conveyor speed : 10m/min (Integral light : approx. 250mJ/cm²)
4. Mesh : 300-350 meshes/inch, Thickness of sol : <10 microns

PRECAUTIONS

1. Skin irritation(P.I.I.) of each color is low(under 2.0). However, it is advised to avoid skin contact. In case of skin contact, please wash with soap and water immediately.
2. Store the ink in a cool and dark place. Stir occasionally to keep stability when the ink is stored for a long time.
3. Hard ink film is the characteristics of GA 41 SERIES. When flexible ink film is required, use RC PF 42 SERIES, RC VX 47 SERIES or RC M 47 SERIES
4. Please refer to MSDS before use.
5. Be sure to do trial print before commercial run to confirm that the product fits the purposes.
