How to use an inkjet printer and how to calculate the size?

Briefly introduce the size design and some basic requirements of inkjet printing.

1, size:

The size of the ink-jet image is the same as the actual picture size, which is different from printing, and there is no need to leave a bleeding part. In inkjet printing companies, there is a blank margin behind the output screen. The general screen margin is 10CM. As shown in the figure, you can agree with the inkjet output company how many edges to leave for buttonholes. The price is calculated in square meters, so the screen size is in centimeters.

The photo output image does not need bleeding, just make a picture according to the actual size.

2, image resolution requirements: inkjet images are often very large, to understand the truth of "I don't know the true face of Lushan Mountain". The same is true for inkjet images. If the big picture still uses the printing resolution, it will kill the computer. However, there are no standard requirements for inkjet image resolution and filtering. Please refer to:

Image area (m2) 180- infinity 30- 180 1-30

Resolution (dpi) 1 1.25 22.5 45

Note: Since most current inkjet printers require images of 1 1.25DPI, 22.5DPI and 45DPI for output, reasonable use of image resolution can speed up drawing.

Generally, it takes 72DPI/ inch to take pictures. If the image is too large (for example, the file size exceeds 400M when displaying the actual size of the new image in PHOTOSHOP), the resolution can be appropriately reduced and controlled within 400 m. ..

3, image mode requirements:

CMKY mode is used uniformly in inkjet printing, and RGB mode is prohibited. Nowadays, inkjet printers are all four-color inkjet printers, and the color and printing color are completely different. Of course, when drawing, they should follow printing standards and inkjet.

The company will adjust the color of the picture to be close to the sample.

Photos can be in CMKY mode or RGB mode. Note that the value of red in RGB is defined by CMKY, that is, M= 100 Y= 100.

4, the black part of the image requirements:

It is forbidden to have a single black value in inkjet and photo images, and three colors, C, M and Y, must be added to form mixed black. If it is big black, it can be made as follows: C=50 M=50 Y=50 K= 100. Especially when you use it in PHOTOSHOP, you should pay attention to changing the black part into four-color black, otherwise a horizontal bar will appear on the black part of the screen, which will affect the overall effect.

5, image storage requirements:

It is best to save inkjet and photo images in TIF format, but be careful not to use compressed format. The following is based on my experience in this industry.

1, drawing, color CMYK mode, resolution 30. Color CMYK does not explain too much. This is the mode used by inkjet printers and photo printers, and RGB is very different from other modes. As far as resolution is concerned, as long as PHOTOSHOP is used for drawing, the resolution of 30 is enough. As long as the inserted picture is clear, you can see the print effect of the picture. Check the print effect of the picture, and set other resolutions before making, such as 100, 200, etc. If the original image is not clear, the printing effect can not be guaranteed at all, but it will improve the processing speed of the machine. So the pictures used as reminders must be clear.

2. The above design. Any design has its own characteristics. Advertising design is not artistic design. In addition to artistic needs, advertising should also pay attention to the publicity effect. For buses, it is necessary to impress others in a short time and highlight the theme. Generally, words can be big.
