I just made ps inkjet tile color matching, but I still don't understand some things, such as grayscale, file replacement, channel and color adjustment. Is there anyone in this line? can

Gray scale indicates color mode. Changing files means changing the color of a certain part of the picture or something, changing the filter. It is used with the negative stack. Channels are often used for matting, RGB colors. In the case of color, you are talking about adding different colors to an object. This is to define the mode used.

Detailed picture:

1, gray scale.

Is the selected material color, for example: rgb is the computer color, cmyk is the printing color, and the gray levels are all gray with background.

2, change the file, I think you are talking about changing the filter.

It is a tool that can replace the part you need to replace with the desired effect.

3. Channels.

It is said that the matting generally uses RGB colors, red, green and blue, choose the channels with obvious contrast, and pick out the desired parts.

4. color. You mean to define a part of the picture and operate the pattern.

You can change the pattern of the part you want to change in the picture to the effect you want.
