How To Fix The Resolution Of An Image In Paint Tool SAI?

Let us look at how resolution can be fixed and why it is so crucial 

Why Does The Resolution Need Fixing?

Often when an image is made larger, it poses issues with the resolution or quality of the image. The edges become blurry, and the image quality is not up to the mark. Such images cannot be used for printing or social media usage. To counter this issue, you must fix the resolution. 

Changing The Resolution Of An Image

  3. From the dropdown menu, choose “Change Resolution.”
  4. Often Paint Tool SAI will adjust the resolution as it sees fit. 
  5. However, you can enter the numbers manually as well.

Use Stabilizer To Make Smooth Lines

If you draw a line in Paint Tool SAI with your free hand on the default setting, you will notice that getting a smooth line with no shakes is easier if you put in a lot of effort. To make this easier for you, Paint Tool SAI has a tool called the Stabiliser. 

This stabilizes the line as you draw it. This tool may sometimes make it harder to draw because of the delay it causes between the pen and the line drawn. However, if you keep a good balance and choose a number that works for you, an issue like this will not bother your drawing experience. 

To use the stabilizer, follow the steps given below. 

  1. Go to the panel on top and select Stabilizer.
  2. In the drop-down, choose a percentage. 
  3. The lower the percentage, the harder it will be to draw a smooth line. 
  4. A good percentage that we recommend is 20%.
