Why is the "CET" sign on the CET-4 report card dark blue and the mine light blue (that is, the color is lighter)?

From June 2005, CET-4, and then it was changed to a report card. Added anti-counterfeiting function. Therefore, many personnel staff can identify the authenticity of the CET-4 report card. Here I offer some of my own experiences:

Misunderstanding 1. The last two strokes of the words "anti-counterfeiting newspaper" must be pressed on the bottom letter "C"; Actually, this is not certain. I have recruited several fresh graduates before, and the transcripts of other schools do not have this. I suspected it was a fake, but later I passed the official website Level 4, and the school confirmed that it was really true, so this anti-counterfeiting was not certain, because the "CET" lithography pattern on the paper was round, and the cutting was not necessarily fixed, but the "CET" pattern was definitely there and it was positive.

Myth 2: There will be several red and blue luminescent fluorescent fibers on the report under the fluorescent anti-counterfeiting fluorescent lamp. Some people say that the luminous fibers have a small arc shape, but after I have confirmed many times, the latter is actually nonsense, because those fiber strips are produced by stirring with pulp and their distribution is irregular. Paper will bend irregularly when it is formed, and it will also become a line with great curvature, so as long as there is one, don't gild the lily;

Third, look at the transparent watermark. No problem. No, it must be fake. The technical content is too low!

In addition, I don't know who can provide the anti-counterfeiting appraisal method for the appearance of the four-level certificate, and jointly contribute to the outstanding talents of the company. Thank you!
