Since mirror effect layer which was formed by printing Mirror Ink (mirror effect ink) on polycarbonate substrate is easy to be damaged by scratch, it is necessary to overprint screen ink as protective layer. However, it was hard for ordinary ink to maintain mirror effect as well as resistance to printed ink layer because it caused dulling in mirror surface.
So, Halogen-Free Ink MIX-HF which balances maintaining excellent mirror effect and resistance to printed ink layer has been newly developed.
MIX-HF ink also enables vivid color mirror effect with no dulling, in combination with TOC-HF and MIR-51000 Mirror Silver.
In this time, we will introduce examples of utilizing MIX-HF with a focus on vivid color mirror effect which is realized in combination with TOC-HF and MIR-51000 Mirror Silver.
Below are the examples of creating postcard by printing. TOC-HF ink and MIR-51000 Mirror Silver have been printed on transparent sheet in combination with MIX-HF ink as protective layer.
Front side for address space expresses beautiful white without the back side pattern being seen through. (Photo taken by slightly raising the card so that you can see the postcard is transparent sheet.
On the back side, mirror effect is such that the watch is reflected in the sheet.
Here is an example of Film Insert Molding.
The photo is of the exhibited objects in IPF JAPAN 2011.
