How many pixels is suitable for ps standard poster size? Ps poster size

How many pixels does a PS poster need? How many pixels does a PS poster need? This depends on the size and output resolution of the poster, for example:

The output resolution of 1 and 600*800mm posters is usually 150dpi, which is converted into 3500*4700 pixels.

2, 800* 1200mm poster, output resolution 120dpi, converted into pixels is 3800*5700.

3. 1200*2000mm poster, with output resolution of 96dpi, converted into pixels of 4500*7600.

4, 2000*3000mm poster, output resolution of 72dpi, converted into pixels is 5700*8500.

Resolution will affect the output accuracy of the poster. The higher the pixel of the poster with the same size, the higher the output accuracy and the clearer it will be. You need to design the appropriate resolution according to your own needs.

Functions and users of AdobePhotoshop(PS):

1, professional evaluation

Photoshop's specialty lies in image processing, not graphic creation. Image processing is the editing and processing of existing bitmap images and the application of some special effects, with emphasis on image processing; Graphic creation software uses vector graphics to design graphics according to its own ideas.

2. The art of binding and design

Graphic design is the most widely used field of Photoshop. Whether it is a book cover, a poster or a poster, these graphic prints usually need Photoshop software to process the images.

Please use PS to make a poster 3 meters long and 2 meters wide. What is an appropriate resolution adjustment? The resolution is set to 300 pixels. No, setting the resolution to 300 pixels before printing will not blur.

For printed products, the resolution is usually set to 300 pixels. Resolution determines the fineness of bitmap image details. Generally speaking, the higher the resolution of an image, the more pixels it contains, the clearer the image and the better the print quality.

In the process of image creation, the correct resolution must be determined according to the final use of the image, and the image must contain enough data to meet the needs of the final output. At the same time, it should be moderate and occupy computer resources as little as possible. If you make a picture for web browsing, the resolution can be set to 72 pixels, which is relatively small, and if you use it for printing, it can't be too small.

Extended data:

In the field of commercial printing, the resolution is expressed by how many lines are arranged equidistantly per inch, that is, LPI(LinesPerInch). In the process of traditional commercial printing plate making, a screen should be added in front of the original image, which is composed of grid lines with equal transparent and opaque parts. These lines are also gratings for cutting anatomical images of light.

Because light has the physical characteristics of diffraction, after it passes through the screen line, it forms dots with different sizes, reflecting the image changes of the original image. These dots are halftone dots, and a halftone dot will not exceed the area of a grid at most. The more network cables, the more layers of displayed images, and the better the image quality. Therefore, LPI is used to represent resolution in commercial printing industry.
