In CDR, converting a bitmap in RGB format to CMYK generally doesn't have much difference in color, it's just a display problem, unless your image is small. If it is a picture the size of a business card, you can set the resolution of the picture higher when turning, such as 600 lines. Of course, it's best to turn in PS so that there is little damage to the color.

RGB and CMYK are two formats... If you want to print, you need to use CMYK, if you use RGB, you may have to change color, which is the basic concept of printing.

There is also a color cast in the CDR software, so when you do it in the future, you can convert it to a CMYK bitmap in CDR, and the number of lines is generally 300-350, which works best.

You can convert to CMYK if you change color in export a jpg diagram to see. Colors are not very different.

My experience is... CDR has a color cast, so I end up grading.

The jpg you export is the printed color effect. than in CDR ...

To put it simply, it is much worse to print the printed documents in CMYK mode and RGB mode!!

Remember!!!

TIFF format is a more accommodating format, compared to CDR, it is less likely to make mistakes in the process of transmitting and printing, and CDR If the network is not very stable, or many times when the work is busy, forget to turn the curve, forget to convert the color to CMYK or retain the original RGB and other problems are more troublesome after printing.

However, our company still directly sends CDR format, because our company will have someone to conduct prepress inspection.

Hehe, who said that CDR can't be printed, if you can't print, go home and farm. Hahaha.

**jpg should be universal.,First convert all the text.,Then all the groups.,And then export it to**format.。

Is your company a printing press or a printer?

The printing press has to get the film (except CTP), if you want to output the film, the CDR file can be.

You go here to study, the package is useful to you.

There are 3 points to note in printed documents:

1. The best export is in TIF format, with a resolution of 300dpi;

2. The color mode is CMYK;

3. File bleeding 3mm;

That's the question!

Printing, divided into four colors (spot color technology can not be mastered), a color represents a cylinder, that is, when we print, a piece of white paper to enter four cylinders, in order to become colorful!

If it is a PSD more file, the same can also be printed, but if the text is four-color (CMYK) it is easy to have problems, of course, the current printing equipment is very good, with four-color words can also be printed, in addition, if the text is Song (font size less than 5), then the problem is big, printing is not good, you can think about it, a so thin word, if you go into four cylinders, in case the paper has a difference of millimeters, there is a problem, CDR default fine line is, the accuracy of the printing equipment is (mm) That is to say, if the same thing can be printed in the simplest printing, we don't have to do such a complex color.

As long as you can understand, printing machinery and equipment, you will know! The rest, you think about it.

No; That is, it can still be printed without turning into curves;

The reason why it is turned into a curve is for convenience;

For example, if you use a font when designing and print it on another computer, the text will be lost, so it will not be converted to a curve.

The size of the word depends on the whole layout, and there is no fixed size.

This is a positive 32 folio, to see whether it is reflexive or positive and negative printing, 16 folio paper rows, 8 fronts, 8 backs, and the specifications are finished products plus bleeding.

It is still based on the size of the finished product, plus the size of the bleeding, and then to spell

Hello, I'm engaged in prepress production, and I'll answer your question. 50% of the hanging net, as the name suggests, the color in the printing is composed of countless dots, 100% of the hanging net in a spot color is called the ground, that is to say, 100% full of the dots of this spot color. Then 50% of the hanging nets mean that the spot color of the printed matter is covered with 50% of the dots on average.

So in the software, how do we reflect the specific distribution value of the hanging network? If you really want to do printing plate making, it is mainly expressed in channels. If it's just for design or effects, the requirements are not so strict, except for channels, you can also use layers.

So I'll talk about the specific method, CMYK is a process color, of course, you can also add other spot colors, I take the spot color magenta as an example, then 50% of the magenta hanging net can be set to 50 in the magenta column in the color picker, and fill it into the layer. There is also a way to fill the layer directly with 100 magenta, and then adjust the transparency of the layer to 50%, which will also work. The channel hanging network is more complicated, each channel represents each color, as mentioned above, in addition to the CMYK mode in the CMYK four channels can also have other spot color channels, then the channel hanging screen ratio is reflected by the special black, so we select the magenta channel in the channel, and then fill in 50% black, then the display in the image is 50% magenta.

Question add, you obviously didn't take a serious look at the production method I wrote above, let's first create a new spot color channel (C13 M20 Y65 K70) in the channel, and then according to the above, the channel is represented by a black K, then 50% of the net (C13 M20 Y65 K70), as long as the spot color channel is filled with 50 black K. I'll attach a diagram to show you the specific settings of the spot color channel, which should be easier to understand.

Generally speaking, when it comes to netting, the color used is a solid color. For example, the black web is not 100 percent, it's 30 or 50 percent.

class. In CorelDraw you fill a circle to 50% black: select the circle, c:0 y:0 m:0

k:50 。When the circle is selected, it is displayed in the status bar.

Show: A paint bucket Color block (black) 50% black (i.e. net value).

Again, do the same in Photoshop, the values are displayed in the Info bar (Window-Info or Straight.

Press F8) to display: C: 0% M: 0% Y: 0% K: 50% Note: Move the mouse when looking in the information bar.

dot to the circle. I don't know if it's clear.,My level is too low.,I can't use the diagram.。 Otherwise, put two screenshots and you will see it all.

Hanging the net is actually transparency.

For example, a 30-net is 30 percent transparency, and a 50 net is 50 percent transparency

Use CMYK, the color magazines you make in CDR are originally vector illustrations, you just need to keep the CDR format, and the printing will generally not change. Look at the RGB version on the computer and send it to the printing house CMYK version, so the colors are inconsistent, and it is best to keep a backup. In addition, the jpg taken by the camera will change color when imported into CDR, but this is almost small, so it will not, and you should pay attention to the format you keep when exporting, and it is best to keep the format of a lower version.

There will definitely be a color cast on camera import, but in my experience with CDR, it's not a big problem. When I do it, I use CMYK to do it, because RGB's color gamut is larger than CMYK, so there is no problem with watching it on the computer after making it with CMYK, and there is basically no deviation in color. As for how to choose the color you want correctly, you can only try a few more times, remember the value of each shade, and enter it directly.

If you don't make something that requires a lot of color, it's not a problem to make it with CMYK and then export it.

CDR in the typesetting we usually choose the color on the right is the color value of CMYK (process color), and the display is similar to RGB color (color of light), the color of each monitor is different, so it is difficult to see the color effect after printing on the computer, so many people will print after proofing or fill in the color value table!

The jpg taken by the camera will be imported into CDR, and the color cast will occur! I don't pay much attention to it when exporting, it's generally RGB and CMYK mode! Whichever you think you want will be the model!

Did you make the picture on paper, and later opened it in a higher version?

If you do it for a long time, make a color difference table by yourself After exporting, the color value will be adjusted, and the LCD monitors have distortion problems, and it is recommended that the display of the brother is better, and the color difference will be closer If the display is good enough, you don't need to adjust the color value after exporting, no way, everyone will encounter this problem, and the only way is to minimize the trouble.

After exporting to jpg format, open it with psd and change the color to cmyk so that it is correct.

You also select CMYK when exporting, so that the final view for customers is CMYK. RGB color and process color can't be close, brightness or something is more beautiful than printing. Therefore, it is not possible to show customers the effect of RGB when it looks good for a while, because this will not achieve the final effect.
