How to choose prismatic reflective film for traffic signs?
What to pay attention to when choosing？
First of all, there should be no obvious scratches, stripes or uneven colors, and the outer surface of the reflective film should be smooth and bright. The surface of the reflective film on the traffic sign should be smooth and bright. If this phenomenon occurs, it will lead to insufficient reflection and other phenomena. The anti-sticking paper on the reflective film must also be kept flat and bright, only in this way can the reflective film be fully utilized.
Secondly, there should be no uneven edges and deformations, and tight and uniform rolls of reflective film should be selected. Generally speaking, reflective film is packaged in rolls. Such reflective film should be tightly, evenly and flatly wrapped around the rigid round core. And the whole roll of reflective film should try to prevent breakage and other situations. Such reflective film can be attached to the traffic sign flatly, and then give full play to its role.
Thirdly, the color of the reflective film is consistent with the traffic sign, and the color consistent with the traffic sign is printed. The color of the reflective film can be reprinted according to the requirements. Thereby playing the important role of reflective film in traffic signs.
How to properly maintain micro-prismatic reflective film？
How to properly maintain car reflective film and extend the service life of car reflective film should start from the following points:
- First, when cleaning, you can choose to wash with water or dry clean. If bleaching is required, you must use chlorine-free bleach.
- Second, since the surface of the car reflective film is directly touched by hand during use, and the product is exposed to a high temperature and high humidity environment (temperature>26.7 °C (80℉), relative humidity>70%) for several weeks, the aluminum layer structure will be contaminated.
- These contaminations will not affect the performance of the product. In general, the actual life of the car reflective film depends on the washing method and wearing conditions. We need to strictly implement the above methods. Only in this way can we better maintain the car reflective film.
How to place the prismatic reflective film in the best position?
There are several ways to try:
- If the object is backlit, we should pay attention to the position of the reflector, and should not put the light-receiving side can be selected according to the actual situation! And when measuring light, pay attention to the side light point! It should be noted that if you measure the highlight part, the dark part will be too dark, and vice versa, the highlight part will be overexposed! So you should add or subtract exposure compensation appropriately. In fact, I think spot metering is most useful at this time.
- For the size of the eye light, it should be slightly less than 1/2! Too large will give you a cataract feeling!
- Similarly, when the person is in the front light state, we can use the reflector from behind the photographer to create backlight, so that the person looks more three-dimensional.
- When the person is in the backlight state, the position of the reflective film should match the angle of the person’s head. The position of the reflective film should be at the same level as the eye, and move up and down according to the angle of the person looking up and down. And the position of the reflective film should be adjusted according to the shadow on the face.
