00:00The inkjet printer is such a genius invention, but it's a pity that this device is still monopolized every day.

00:07If we enlarge the printed photo, we will see that the photo is made up of previous ink droplets.

00:12Not only that, the printer can print with only four kinds of ink.

00:16What is the magical principle behind this?

00:18The core lies in the nozzle.

00:20There are a large number of nozzles distributed on it, each thinner than a hair.

00:24The nozzle is designed to be wide at the top and narrow at the bottom, which creates negative pressure.

00:30Once printing starts, the heating resistor above will heat the temperature to 100 degrees in 0.00001 seconds,

00:39and the high temperature will cause the nearby ink to form bubbles.

00:43These act as pistons and push out the ink below.

00:47Due to the viscosity of the ejected ink, it will form a main droplet and a trailing droplet.

00:53They fall at a speed of 10 meters per second.

00:55The nozzle is 1 millimeter away from the paper, so it only takes 1 ten-thousandth of a second to reach it,

01:02and it is absorbed by the paper in a very short time.

01:05The nozzle is connected to the printer through a soft tube.

01:08A non-inflatable motor drives the belt and pulley to move the nozzle, and a shaft stepper is added to move the paper.

01:15This is the basic structure of the printer.

01:17So how does one use four inks to print colorful photos?

01:21You might think of using a mix of red, green, and blue.

01:24Let's do a small experiment first.

01:26If you use a red and green flashlight to add and mix, you will get yellow,

01:31but if you mix red and green ink, you will get a very turbid yellow.

01:35In fact, this is the difference between additive color mixing and subtractive color mixing.

01:40For self-illuminating shades, mixing the two colors increases the brightness, but the ink itself does not emit light.

01:47We can see the ink because light hits the ink and then reflects into the human eye.

01:52This process will filter out part of the light.

01:55For a better understanding, let's magnify the ink droplets to a microscopic perspective.

02:00If the green molecules in the lower layer want to reflect green light,

02:03they must penetrate the green and red molecules in the upper layer,

02:07but this process will be blocked by the red molecules, producing black in this area.

02:12Similarly, the red molecules in the lower layer will also be blocked by the green molecules in the upper layer,

02:18and the resulting black color will cause a yellow change.

02:21To give another popular example, the gray hair we see with the naked eye

02:26is actually the result of a mixture of white and black hair.

02:29So obviously, the three primary colors of red, green, and blue cannot be used directly in the printer.

02:35The solution is easy. Just replace red, green, and blue with their complementary colors.

02:40Cyan, magenta, and yellow.

02:42When the nozzle releases a drop of cyan ink and then quickly releases a drop of yellow ink,

02:48the two mix together to create an intoxicating green color.

02:52The diameter of the mixed droplet is only 0.05 millimeters,

02:56and a variety of colors can be obtained in this way.

02:59So what should you do if you want a lighter green?

03:01In fact, you can get a lighter green by increasing the spacing,

03:04which will make it appear darker, but the spacing is always limited.

03:08What if you want a darker green?

03:09This is when black ink comes in handy.

03:11Mixing black into green ink will result in dark green.

03:14The more black you mix in, the darker the green will be.

03:18So as long as you use the four colors of cyan, magenta, yellow, and black,

03:22you can print up to millions of colors.

03:24And a photo of A4 size can even have a motorcycle.

03:27We have to admire the wisdom of human beings.
