While this feature is essential for most digital artists, some users may prefer to disable it for specific projects or to achieve certain effects. Disabling pen pressure in Paint Tool SAI requires adjusting the settings within the software, as well as ensuring that the pen tablet drivers are installed and updated.

What You'll Learn

Ensure Min Size is under 100% in brush settings
To disable pen pressure in Paint Tool SAI, one of the steps is to ensure that "Min Size" in your brush settings is under 100%.
To do this, first, open SAI and go to the menu bar at the top. Click on "Other (O)" and then "Options (O)". This will open up the "Digitizer Support" tab. Here, you will find the "Min Size" setting under the brush settings. Make sure that this is set to a number under 100%. Lowering the "Min Size" allows for a higher range of pen pressure. For absolute pen pressure, you can set the "Min Size" to 0%. However, some artists prefer to adjust this setting to suit their preferences.
It is important to note that this setting may vary depending on the tablet you are using. Additionally, ensure that your drivers are installed and updated, as this can also impact pen pressure sensitivity.

Uninstall and reinstall Wacom driver
If you are experiencing issues with your Wacom tablet, one solution is to uninstall and reinstall the Wacom drivers. This process can be done on both Windows and Mac operating systems.
First, you will need to uninstall the Wacom driver. To do this, go to Programs and Features and look for Wacom in the list of installed programs. If you cannot find it there, open the Device Manager, expand "Human Interface Devices", and check if "Wacom Tablet" is listed there. If it is, right-click on it, choose "Uninstall", and then plug in the tablet and run the installer.
After uninstalling the driver, you will need to reinstall the latest Wacom drivers. There are two ways to do this: manually or automatically. For the manual method, visit the Wacom support page, search for your device model, and download the correct drivers that are compatible with your operating system. Then, open the downloaded file, run the installer, and follow the installation wizard. If you prefer the automatic method, you can use a tool like Driver Easy, which will automatically download and install the latest Wacom drivers for you.
Once the installation is complete, restart your computer and reconnect the tablet. You can then test your tablet by opening the Wacom Desktop Center or going to Apple > System Preferences > Wacom Tablet. Ensure that all pen and button functionality is working properly before restoring any preferences that you may have backed up.
It is important to note that a simple restart of your computer and Wacom Service Driver can sometimes fix issues without needing to uninstall and reinstall the drivers. Additionally, ensuring that your Min Size and "Click detection pressure" settings in SAI are optimized for pen pressure can also help address pen pressure issues without requiring a driver update.
