Let's give you a detailed analysis of the various methods for converting color images to grayscale.
Tutorial sharing:
Method 1: convert menus to grayscale
This may be the quickest, at least the most common method. Select a file and select "edit-edit color-convert to grayscale ".
Click "next page". Let's take a look at the following method.
Method 2: adjust the color balance
This method can be used to control the black. Select a file and choose Edit> Edit color> adjust color balance ". Select Grayscale from the drop-down menu, and click the preview and conversion check boxes to adjust the percentage of black using the slide bar.
Method 3: reduce saturation
If you want to control the gray scale more, try to adjust the color balance option. Select a file, select edit-edit color-re-color image, or click the color wheel icon in the control panel. Either of the two methods can bring up the real-time coloring dialog box. There is a slide bar at the bottom of the dialog box. There are two buttons on the right of the slider. Click the button like the primary key (in CS 5, unlike the primary key, it is a down arrow on the left and a button on the four horizontal lines on the right ), select global adjustment from the drop-down menu, and pull the saturation slider to the left to-100%. Different effects can be obtained by pulling the brightness, color temperature, and brightness slide.
Method 4: re-color the image
If the above method does not have enough control items, you can try to re-color the graphic option. First, if the default print color palette is not enabled, we need to load it. Open the color palette Library menu on the left at the bottom of the color palette panel and select default color palette-print. Drag the grayscale color palette into the color palette. If your default print color palette is not opened, you must open it first.
Now you can select a file, edit it, edit the color, and re-color the image, or click the color wheel icon in the control panel. In the "re-coloring" dialog box, select the gray color palette set in the right color group. Now the work becomes grayscale, and the "re-coloring" dialog box allows you to edit the grayscale color palette based on the primary color set.
Click the Keys next to the slide bar at the bottom of the re-coloring dialog box (see the translator's note above) and select CMYK. Select the primary color from the current color bar and use the K (black) slider at the bottom to edit the percentage of black. If you hover your mouse over the grayscale color palette in the new column (the new column is next to the current color bar on the left), you will see an arrow in the drop-down menu. I like to retain the original colors, but it is not difficult to try different effects.
All right, the above information is the detailed multi-color image to gray-scale method provided by Illustrator's software users to parse and share all the content, you can see the users here. I believe that you are very clear about the method, so you can follow the tutorial of the small editor to try the effect.
