The higher the number of outlets, the richer the level of the product?

A dot is the smallest unit that makes up an image. It is divided into amplitude modulation outlets and frequency modulation outlets.

To put it simply, the density of the dots is fixed, and the color depth is expressed by adjusting the size of the dots, so as to achieve the transition of tones. The size of the frequency modulation network is fixed, and it is achieved by controlling the density of the network. Amplitude modulation dots are the most widely used outlets.

Its dot density is fixed, and the shade of color is expressed by adjusting the size of the dots, thus achieving a transition of tones. The size of the dot is determined by the coverage of the dot, also known as the ink rate.

Generally, it is customary to use "Cheng" as a unit of measurement, for example, the outlets with 10 coverage rates are called "Yicheng outlets", the outlets with a coverage rate of 20 are called "Ercheng outlets", and the outlets with a coverage rate of 0 are called "out of the net", and the outlets with a coverage rate of 100 are called "field". The gradation of printed matter is generally divided into three levels: light tone, middle tone, and dark tone.

The dot coverage of the bright part is about 10 30;The coverage rate of the outlets in the middle part is about 40 60;The dark part is 70 90. The shape of the dots in this segment.

The shape of the dots in printing is not just a single circle in everyone's imagination, and the shape of the dots in the case of 50 ink rate can be divided into: square, round, and diamond.

The square dots are at 50 coverage, in the shape of a checkerboard. Its particles are relatively sharp and have a strong ability to express layers. Ideal for lines, graphics, and some hard-toned images.

The number of dot lines is mainly related to clarity. For example, 1024*768 is better than 800*600. Image levels are mainly related to contrast and brightness. The contrast and brightness indicators are good.

The higher the number of dots, the clearer things will be.

The outlets of silk screen printing should be smaller, and the offset printing should be 175 nets and 200 nets.

The number of dots is the number of dots per unit length (lpi per inch or lpc per centimeter). The higher the number of dots, the finer the subtle expression level of the image. There are two discernment rates:

One is the resolution of the digital image (ppi or dpi), and the other is the recording resolution (SPI) of the output device, and the number of dots per unit area is the square of the number of dot lines. For example, this 300LPI means that there are 90,000 outlets per square inch. In general, the scanning resolution of the image is taken by 2 times the number of dots.

Theoretically, the reciprocal of the output recording resolution = the minimum dot diameter of the screened image.

You should mean: Image Resolution (PPI) and Printing Resolution LPI (Number of Screens). They are both related and different:

The image resolution (PPI) is higher than the printing resolution (LPI), generally 2 or more pixels generate 1 dot, that is, LPI is about half of the DPI.

Since the printed matter is composed of dots, the number of printed images plus screen lines refers to the number of screen lines per inch in the horizontal or vertical direction of the printed matter, that is, the number of network cables hanging on the screen. It is called the number of network lines because the earliest printed matter dots were wire-like. The unit of the number of connected network cables is line inch, referred to as LPI.

For example, 150LPI means that 150 network cables are added per inch. The larger the number of meshes and the more nets, the denser the dots and the richer the level expressiveness.

Because computer images are dot-matrix, that is, they are composed of pixels (the smallest unit of an image is called a pixel). Image resolution can be visually understood as the number of pixels in a unit length of a line in the horizontal or vertical direction, and the more pixels used to describe the line, the higher the resolution. The unit of image resolution is generally pixels perinch, which is usually expressed in English as ppi.

For example, if an image has a resolution of 300 ppi, it means that it has 300 pixels per inch horizontally or vertically. An image with a resolution of 720i means that it has 72 pixels per inch horizontally or vertically.

Some devices have similar resolution to image resolution, except that they are expressed by dots, so they are represented as dot per inch, or DPI for short. For example, an image scanner with a resolution of 1200dpi has an image input accuracy of 1200 dots, or pixels, per inch. The output accuracy of the 3600dpi laser phototypesetting machine is 3600 laser points per inch.

Let me tell you. The number of printing lines is the term for the printed product. ** is also the term for resolving pixels.

The higher the number of lines in the print, the clearer the quality, the highest will not exceed 1000 lines, no 3600 as you sayI make a Heidelberg five-color press (CP2000) printing machine, and I can only print up to 600 lines. This is the world's top printing press.

There is also that you take a **, and a print (the box is fine), use a magnifying glass, and look. Look at the difference, and you'll understand.

A network cable is the number of wires that are added to the network. The unit of expression is LPI, such as the general line can use 75 90 line (75 90 lpi). 150 175 lines (150 175 lpi) for color offset printing.

Because the previous network network was wired, it is customary to refer to all network encryption degrees as network cables. To be precise, the laser phototypesetting machine interprets the precision (resolution) of the digital file on the film. The so-called network cable is the clarity of printing, and we are talking about the resolution to represent the clarity of the image.

The relationship between the network cable and the resolution is: 1.5 times the network cable is equivalent to the resolution (generally speaking).

Feng Xun rate determines the clarity of **, and the printing line tree fern is not aware of the relationship.

Conventional printing (with film printing) is to use the xx line to indicate its accuracy; Digital printing machines often use xx resolution to indicate their accuracy, which are two different forms of printing.

1. There are two forms of expression for resolution:

Image resolution (PPI): Refers to the number of pixels per unit length of a bitmap image, such as 72 pixels inches.

Output Resolution (DPI): Refers to the points that can be produced by the printing device per unit length, such as 1440 dpi inches.

2. Number of lines (LPI): refers to the number of lines per unit length of the separator screen, such as 175 line inches.

The relationship between the three is as follows:

1. The relationship between image resolution and the number of screen lines determines the quality of printing details, and usually the image resolution is a multiple of the number of screen lines. Hypothesis: If you want to output 175 lines of film (generally offset presses use 175 lines of inches), in the computer design and production, the original large bitmap resolution of the import link is between 260-350 (ppi), too small affects the quality, too large affects the speed of the computer and the quality can not be better.

2. As long as one of the image resolution and output resolution is too low, it will not be able to print high-quality products, and the image resolution is generally 1 4-1 3 times of the output resolution. For example, if the resolution of the printer is 1440, then the original large image resolution is required to be between 480-360 (ppi).

3. The concept of printing resolution 3600 you said is a bit vague, to make it clear whether it is 3600dpi inches, as far as I know, it doesn't seem to be that high.

It refers to the number of lines per inch of the printed matter, and the number of lines per inch (LPI, that is, the number of lines per inch) of the printed matter, in other words, the "number of lines" is the density of the printed network lines.

In the process of printing, the size of the dots is controlled by the density of the network cables, and the smaller the number of network lines, the easier it is to see the dots of the printed matter with the naked eye. In terms of practical application, the number of screen lines at the time of printing will be selected according to the type of paper.

The general law is that the rougher the surface of the paper, the lower the number of screen lines used in printing (the thicker the screen lines will be), otherwise the printing quality will not be clear due to the dense screen lines, resulting in ink diffusion and stickiness.

First of all, the number of lines used in printing is by no means the number of lines in image resolution.

1, there is a precision when the film output, this accuracy is expressed by the number of lines, the prints we generally use are 175 lines, that is to say, there are 175 points in an inch of distance equidistant distribution, from the point to the line to the surface, and the size of these points is also particular, usually we use 0 10% 20% 30% 100% to explain the depth of color (shade).

The number of threads can be adjusted according to the customer's product requirements.

2, "The overprint angle of different colors of ink should be different", that's for sure!

Why? Because these lines composed of dots will produce some plaques when they intersect each other, and these plaques will have the least obvious effect at the angle of C15° M45° Y90° K75° (that is to say, the single area of the plaque is the smallest, and the color of the picture will be the most flat), and the plaque will become larger and the quality of the print will be reduced if the color and corresponding angle are used incorrectly.

Let's talk about what angles, points, lines, and surfaces are.

Take the 175 line as an example: there are 175 points in an inch, and 175x175 points in a square inch (175 on the horizontal axis, 175 on the vertical axis, and the angle between the horizontal axis and the vertical axis is 90° at all times).

For example: c15°, the right hand direction of the horizontal axis is raised to 15°, and the vertical axis is naturally 105°.

m45°, at this time, the right-hand direction of the horizontal axis is raised to 45°, and the vertical axis is naturally 135°.

。And so on.

The "shade" of color is represented by the size of the "dot" (note: not "sparse"), from 0 100%, 0 is colorless (white), and 100% is solid (saturated).

The 175x175 "dots" in one square inch become smaller and larger to reflect the change in color shades.

If there is anything you don't understand, you can send me a message

The number of printing lines refers to the fineness of the print, and in layman's terms, all the colors that the eye sees are answered by one.

When these outlets reach a certain density, they form network cables, and in the specified area (I can't remember how large the area is), the number of network cables is called the number of lines. Therefore, it is easy to conclude that the higher the number of lines (the higher the number of network cables), the more detailed the print!

The number of lines, that is, the number of network lines. The unit is dpi, which is dot per inch, how many dots are there per inch. 300 lines means that there are 300 dots per inch, and 150 lines are composed of 150 dots per inch, and the higher the number of lines, the clearer the image.

The first question is actually a prepress question, which has already been explained!

The second problem is actually the problem of overprinting, now printing is divided into AM mesh and FM net, commonly used is FM mesh is to pay attention to the angle of the dots, the general situation is black 15 degrees, red 45 degrees, blue 75 degrees, yellow 90 degrees.

Image resolution The general printing quality is more than 300 lines.

It depends on the contrast of the network cable.

The number of lines of a rotary encoder is the number of pulses generated in one revolution, that is, the resolution, and the higher the number of lines, the higher the resolution.

No, the resolution doesn't matter the number of lines.

The number of lines is more, the output signal is more, and you have to read the manual for the resolution size!

Printing and screen is out of the film or out of the CTP version before the addition, the design and production of documents is not careful, the screen according to the printing press and customer requirements to decide, fine level of high pattern, with Heidelberg and other imported printing presses, out of 200 lines of film, the general printing press 175 lines, the higher the number of lines, the smaller the dots, 200 or 175 lines for printing magazines, 133 lines for printing newspapers (rough paper surface).

It's bleeding... Or it's color-coded... I guess it's because your colors are too miscellaneous. Each color is mixed with CMYK.

Movie money in the coreldraw plus outlets.

What kind of outlet, it's bleeding???

The number of lines and the resolution of an encoder are one concept.

For example, a 2500-line encoder is actually a 2048-line 2 to the 11th power, so it's called an 11-bit encoder.

Also called 2500 wire encoder.

What is the accuracy, that is, the error of the rotation position of the motor every time, the error is small, the accuracy is high.

A circle of 360 degrees, 2048 pulses, 11 bits.

A 360-degree 65,536 pulses 16-bit encoder.

In this way, the encoder with a high number of bits divides the number of 360 degrees by the pulse.

There are currently 18-bit encoders, 20-bit encoders, and 32-bit encoders.

Absolute encoders with more than 20 digits are restricted for import. Because it can be used for military purposes, it cannot be imported.

Encoders with high digits can read accurately, but the accuracy is analyzed on a case-by-case basis.

It's like a watch, a watch with only a minute hand and an hour hand.

and a watch with seconds, minutes, and hour hands.

One can read the second and the other can only read the minute.

But after a year, perhaps only the minute hand, the hour hand is not slow or fast compared to the standard time--- with high precision.

And the one that could read the second hand was one second slower a day, and a year later it was 365 seconds slower than standard time. --Low accuracy.
