Weather resistance
The weather resistance is influenced by the factors like the printing media, Optical output, (watt), distance between the printed media and UV light source, using situation (sun light) and etc. We will show the several data as following. The color fading starts due to being exposed by UV light. Therefore, under the condition of not exposed by UV light, the color fading will not be occurred. If the printed material would be placed on the dark spot without being exposed by sun light or a shut page of magazine without being exposed by UV light, the color fading on the material or page will not be started.
TRICK INK (UV ink) is luminous itself by reacting against the energy of Ultra Violet Ray, which is equal to start losing and fading the luminous ability of the ink.Therefor, the under mentioned data of the fading means the data when the fading of the luminous color is getting to be observed remarkably. In usual case Red color is fading earier, then the total color balance of picture is getting lost.
The followings are shown the weather resistance under the suitable distance from light source and proper watt. Basic sample media is “Shiraoi” high quality paper.
※Evaluated figure for TRICK PRINT inks since Dec. 2010.
The followings show the relation between the light source and distance. (The exposing hour is settled 12 hours in a day).

About fading of color
The fade of color on TRICK PRINT means not fade out completely. But the luminous power has been losing gradually. The fading speed differs in each RGB colors. Red color is fading firstly, then blue color and green color in order. As the fading speeds are difference by RGB colors, we decided the starting day of fading is when the color balance of the picture is lost. Therefore, the total picture shape keeps more longer life than the estimated figures.
For proper wattage and distance
Even same distance, weather resistance is difference depend upon the output power of electricity (watt). So, the suitable watt must be used in order to prevent the unusual early fading out.
The suitable distance is
The suitable distance is thought the place where the printed object is watched most clearly and comfortably by changing the distance between light source and the object to the forward or the back side. If the distance is too close, the object is lighted too much luminous and the color would be faded earlier. Therefore, the suitable distance should be necessary to void of the early fading.
As above, the suitable distance is influenced by the surrounding circumstances. In the case of much lighted space, the distance becomes short and it needs high power (watt), in which case the fading speed becomes higher. On the contrary, the surrounded circumstance is the much darker, the distance is extended much longer and the fading speed becomes much more slowly. The weather resistance is getting up.
TRICK PRINT INK is very weak against sun ray. Therefore it is not suitable for the outdoor uses.
The UV rays included in sun ray are always so strong that they make early fading of TRICK PRINT INK. When TRICK PRINT would be whatched under the sun ray, it would be seemed not being luminescence. But the other visible rays of sun ray are too much strong, so the luminescence UV of TRICK PRINT cannot be recognized. Under the sun shine, TRICK PRINT INKs have been getting to be exposed by the strong UV of sun ray and have been fading quickly. Under the sun ray, the printed picture of TRICK PRINT would be seen faintly. Under a normal fluorescent light (which is not included UV ray), the printed picture of TRICK PRINT couldn’t be seen at all. (Remarks: There are some normal fluorescent lights which have slight UV ray.)
