When you check the some of reflective items carefully, you will find there is a line on the surface of these slap warp or badges,s, etc. sometimes it is a very thick one and sometimes it is a very thin line. like the above photo. The left is a 3M one and the right is a Reflexite material.
Reflective vinyl raw materials come in different sizes like USA material comes in a roll (for example, 3M material is in size of 45.7cmX100meter) while China-made material comes in a sheet (45X45cm). But it is the same that Every 23cm on the surface for the raw material, there will be a line. This is not a quality problem. Because the size of the molding which produces the reflective vinyl is about 23X23cm. So it will not possible to avoid this line when you produce items with a size of more than 23cm.
Normally the client will accept it. because I think we mainly want to use its safety function instead of its looking. but it will be better to explain this point to the client in advance.
