The biggest suspense in movies is who is the real painter?
In order to find out who is the real painter, there are not a few people scratching their hearts and lungs. People who have seen movies are very entangled in this matter.
If you understand these two particularly interesting lines in the movie, it is not difficult for you to know who the real painter is.
Many friends may have questions after watching the Chinese blockbuster "Warrior" recently released: Why do dollar owners need painters to draw by hand, but can't copy them directly?
The answer is, of course, you can't copy directly, because copying will have moire, which has been mentioned more than five times in the movie. Even scanning plate-making will have optical influence, and copying will be more serious.
Moire fringe is a grating effect caused by reflected light entering electronic equipment after the fringe reaches a certain density. It will lead to the interference phenomenon of ripples or color stripes on the image. This Baidu has many legends to see.
Hand-painting is to enlarge these stripes in equal proportion, not too dense. In this way, interference can be avoided or reduced from the source through optical zoom processing in the plate making process.
So the dollar version of the film is very big, divided into many parts, made separately, and finally put together.
Just find a picture. The portrait background consists of concentric elliptic lines. What is the moire pattern emphasized in the movie? Let me give you an example.
In fact, when designing coin patterns, people always draw big pictures, because no one dares to say no to shaking hands.
Generally speaking, for old dollars, hand-painted banknotes are to prevent moire, and the specific process is: scanning → manual copying → scanning → restoration → plate making. For other currencies, hand-drawing can handle the color matching process. If you want to deal with the rainbow print, you can only draw another version of the rainbow print. Of course, if the transition changes in the printing process are different from the real banknotes, they will also be found, so you can only spend a lot of energy and cost to debug them yourself.
