High-value addition to the glass substrate by applying high opaque decoration Two pack type Halogeen free printing ink for glass substrate
Introduction of GLS-HF ink（3）
A special news to the customers who consider utilization of glass substrates!
This time, we will introduce the excellent opacity function of GLS-HF Opaque Black / Opaque White Ink, two-pack Halogen Free type ink designed for printing on glass substrate.
1. Organic type of GLS-HF Opaque Black/White ink that realize high opacity
Organic type of GLS-HF Opaque Black(GLS-HF979Black)/ Opaque White(GLS-HF679White) ink has excellent opacity.
These inks realize beautiful colors without being effected by the backlight even when being used for decorating outside frame of the touch panel. (The cases of Opaque Black are described below.)
OD value:(Abbreviation of Optical Density: Comparison of absorbance )
| GLS-HF919Black | GLS-HF Opaque Black (GLS-HF979Black) |
|
|---|---|---|
| OD value (Thickness of ink layer 5µm) |
3.3 | 5.1 |
2. Cases of utilizing GLS-HF Ink, two-pack Halogen Free type ink designed for printing on glass substrate
Case 1. Comparison of glass decoration by GLS-HF Opaque Black and the Black ink
Before irradiation of backlight
| GLS-HF919Black | Opaque Black (GLS-HF979Black) |
|---|---|

|
After irradiation of backlight
| GLS-HF919Black | Opaque Black(GLS-HF979Black) | |
|---|---|---|

| This can not block the light completely. | This maintains beautiful Black color without being effected by the backlight. |
GLS-HF919Black that is the normal standard color can not block the light completely and becomes reddish color when irradiated by the light (backlight) from behind.
In contrast, GLS-HF Opaque Black(GLS-HF979Black) maintains beautiful Black color without being effected by the backlight.
Case 2. Comparison of glass decoration by GLS-HF Opaque White and the other colors
The difference between GLS-HF Opaque White(GLS-HF679White) (Right side) and GLS-HF619White (Left side)
When placing the black color on backside, GLS-HF Opaque White(GLS-HF679White) (Right side) expresses white color more vividly, compared with GLS-HF619White (Left side).
