Select Layer 1 and remove the eye mark on the Background

When seen in this picture, there are 2 colors: Red and Black, and the way to get raster is by separating the color, how to separate the color, note the following steps:
We take the black color first,
On the menu bar select Select then Color Range, as shown below,
On Select replace with black (Shadows)

If it has been replaced with black then click OK

Then when you see the dotted line / flickering on the image, just press Ctrl-J on the keyboard, it will automatically form a colored Layer 2 that we wanted to separate, namely Black.

 And now take the red color of the image, first remove the eye mark on layer 2,

red

And do the steps like this, but for the red ones, change the Select on the Color Range (Reds). click OK, then press Ctrl-J

Is that raster?

If you do it right then we now get 2 images with different colors, it's not finished because we still have to change it to raster.
Before we go on, maybe someone asks "what is raster?", Raster is an image that is formed into very small dots with a form that can be set, "why do you have to use raster?", Because it gives an easy way to get little dimensions with results look smoother and more similar to the original image.
