Black technology that makes the pattern of matte black box packaging move!

    

1. Realize the animation effect of matte black box packaging:

     

In the previous issue, I showed you the use of striped grid sheets and corresponding printing images to achieve the animation effect of matte black box packaging: in this article, I will give a brief introduction to this matte black box packaging technology and state that matte The principle of black box packaging, and provide a tutorial on how to make a matte black box packaging design.

   

    

Raster animation, also known as SCANIMATION in foreign countries, is described in an easy-to-understand sentence as unplugged animation matte black box packaging. The realization process is to use a striped transparent film in a jagged matte black box In the packaging illustration, a dynamic effect is achieved by moving the matte black box packaging transparent sheet.

   

     

2. The principle of moving the matte black box packaging:

    

Let's start by taking a look at the mysterious hidden function of the brain that you may be using all the time without knowing it:

     

① Why do two static matte black box packaging pictures superimpose and perform relative motion, resulting in a moving picture?

     

When the brain sees things that are similar in matte black box packaging, it recognizes them as the same thing and compensates for what it doesn't see.

For example, when the traffic lights on the road change, you may feel that the lights have moved a position. If you flip through the book quickly, you may see that the illustrations inside are changing rapidly, resulting in a moving picture.

The literal meaning is not as simple and intuitive as the picture. Do you think this person is shooting basketball? That’s right, the dynamic expression pack is actually the principle of matte black box packaging.

   

     

② The brain's mysterious matte black box packaging works, automatically complete incomplete illustrations

     

When a part of the matte black box packaging is hidden and invisible, the brain will supplement the hidden part of the matte black box packaging through experience and knowledge, and recognize the whole matte black box packaging immediately.

Let's understand this sentence briefly and look at the matte black box packaging below. Although half of the matte black box packaging is missing, I don't think you don't know what it looks like.

The supplementary mechanism of the brain should have presented the whole part of the matte black box packaging in your mind.

    

     

3. Matte black box packaging needs to pay attention to three points

    

3.1. Matte black box packaging hidden parts (gap pieces) are regular

     

This is the matte black box packaging image covered by irregular slits. Even though we have seen the pattern at the bottom of the matte black box packaging before, it is still difficult to deduce what the matte black box packaging is like, or the matte black box There will be considerable deviations between packaging and reality.

    

    

3.2. Matte black box packaging The proportion of hidden parts (gap pieces) is less than 80% of the whole

     

The following are three pictures with different hidden areas of matte black box packaging. As the hidden area of matte black box packaging gradually increases, it becomes more and more difficult to identify matte black box packaging.

Later I will explain in detail the matte black box packaging frame number in the scan corresponds to the width of the black stripe. To increase the matte black box packaging frame count, you need to widen the width of the matte black box packaging black stripes. It is very important to figure out the width of the black stripes for each matte black box packaging illustration. Usually, the maximum frame number of matte black box packaging for scanning is 5 frames. Do not add too many frames, this will cause the width of the black stripes of the matte black box packaging to be too wide, blocking too many images of the matte black box packaging, and the effect cannot be achieved. I will explain how to calculate this in detail below.

    

     

3.3. The visible part (illustration) of matte black box packaging has continuity

    

As shown in the figure, there are two illustrations of matte black box packaging that are not continuous with each other, one circle and one square. The dynamic diagram of matte black box packaging created in this way is a transformation of a circle and a square, rather than a continuous matte black box packaging animation effect.

   

     

Of course, if you don't pursue the dynamic effect of matte black box packaging, you can actually ignore this one. For example, you need to realize the alternate appearance of the four words "Happy New Year" through the change of the matte black box packaging grid.

Now that the basic principles and precautions of matte black box packaging are finished, let’s start the most important part: how to make a moving matte black box packaging?
