分析喷绘写真广告画面出现褪色的原因?

一是紫外光的直射,二是黑墨水中的染剂碰到了一些带有空气氧化氧化性的化学物质促使染剂的化学结构发生了转变,进而造成了退色状况。紫外光的直射退色自然与紫外光的高低相关,我们知道室内写真黑墨水制做的照片是置放室内无太阳照射的地区,只承担一些室内灯光效果的直射,在这类状况下,假如墨中的染剂抗晒级别为5~6级,那麼它的室内储放時间二三年(无视觉效果比较严重退色),因此 当碰到退色时先需看照片有没有被紫外线照射过强状况,如广告灯箱中led灯管的紫外线是不是超标准,应用伪劣led灯管而造成灯片界面退色是灯片退色的普遍缘故之一。
One is the direct irradiation of ultraviolet light, and the other is that the dye in black ink encounters some chemical substances with air oxidation, which makes the chemical structure of the dye change, and then causes the discoloration. The direct fading of ultraviolet light is naturally related to the level of ultraviolet light. We know that the photos made by indoor photo black ink are placed in the area without sunlight, and only bear the direct effect of some indoor lighting. In this kind of situation, if the dye in the ink is sun resistant grade 5 ~ 6, then its indoor storage time is two or three years (no visual effect is more serious fading), so it's not easy to use When encountering fading, we need to see if the photo is too strongly irradiated by ultraviolet light, such as whether the ultraviolet light of LED lamp in the advertising light box is beyond the standard, and one of the common reasons for the fading of lamp sheet is the application of fake LED lamp.

退色的另一方面缘故是染剂碰到了一些有空气氧化氧化性的化学物质,当黑墨水打在有镀层的物质上,上边又覆到了含有胶原纤维的膜,假如镀层或膜上带有还原性化学物质都是会有退色状况产生,例如在我们的手里一不小心沾有黑墨水,十分不易洗去时,用84消毒杀菌一洗一定会洗去,也就是这个缘故,产生这类退色一般地说有下列特性:
Another reason for fading is that the dye encounters some chemical substances with air oxidation. When the black ink hits the material with coating, it is covered with a film containing collagen fibers. If the coating or the film has reducing chemical substances, there will be fading. For example, when we accidentally touch the black ink in our hands, it is very difficult to wash it off, we can use 84 to eliminate it This kind of discoloration has the following characteristics in general:
1、浅色系的或着中间色的界面觉得十分快并且時间有时候只几个小时。
1. The interface of light color or intermediate color feels very fast, and sometimes it takes only a few hours.
2、这类界面就算是放到在黑暗中没光的地区也会迅速退色。
2. This kind of interface will fade quickly even if it is placed in the dark area without light.
3、喷绘界面的色调褪一定水平就没有褪了(表明反映了一部分),详细情况不一样会稍有差别。现阶段中国销售市场一般的原材料镀层基础通关,灯片差一些,因为膜导致退色的状况也是经常发生,这一点大家可根据一些实际具体检测掌握。也有便是写真喷绘界面退色,化水的缘故是因为在沒有等界面上的写真黑墨水彻 底干躁以前就过膜。
3. If the hue of the inkjet interface fades to a certain level, it will not fade (indicating that it reflects part of the image). If the details are different, it will be slightly different. At this stage, China's sales market in general raw material coating basic customs clearance, lamp chip is poor, because the film led to the discoloration of the situation is often happening, this point you can according to some actual specific detection grasp. There is also a photo jet interface fading, the reason for water is because the black ink on the interface is not completely dry before the film.
