Specifically, what is typesetting?

Here is an introduction.

If you learn imposition, the computer will be o in a month. But the design of typesetting is more complicated, from the founder to Word, Wps, Freehand, Pagemaker, Illustrator, CorelDraw, Indesign and so on. It is recommended to learn Word and Indesign. Learn in half a year and master in one year.

Some simple requirements for making and outputting images in inkjet printing and photography.

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 negotiate 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.

2, image resolution requirements:

Inkjet images are usually very large, and so are inkjet images. If the big picture still uses the printing resolution, it will kill the computer. However, there is no standard requirement for the resolution of inkjet images. The following resolutions are used when I use different sizes for your reference:

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. The current inkjet printers are all four-color inkjet printers, and their colors are completely different from the printing colors. Of course, when drawing, the inkjet printer will follow the printing standard, and the inkjet printer 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.

About the number of points, it depends. Painting is generally 30dpi, and photographing is generally 72dpi. If the picture is larger, it can be reduced accordingly. The minimum number of points I have done is 10dpi, 300 square. If it is large, it can be divided into several documents. Photos are generally not less than 50dpi. As for the small number of points, the picture will not be blurred, but will produce strong sawtooth. On the other hand, if you increase the number of points and enlarge the picture, it will be blurred and the sawtooth will be less obvious. Generally speaking, you can do both and think for yourself.

In addition, there is an outdoor photo machine in the advertising industry, which is dedicated to being considerate. High cost and high price.

Car sticker materials are: white glue, imported vinyl, domestic vinyl. The material can also be painted lamp cloth, photo pp paper, flag cloth, single-sided transparency (used on glass or organic film) and so on. Ink is oily ink. The painted picture has the characteristics of accurate portrait and long storage time of inkjet printing.

In these categories, the printing accuracy is the best and clearest, at least at 300dpi (that is, the resolution), followed by outdoor photos, photos and inkjet. The accuracy of inkjet printing is relatively low, and there are usually burrs at close range. However, the spray-painted pictures are generally hung on the external walls of buildings, and the overall effect is good from a distance. Different production methods have different requirements for design according to different customer needs.
