Digital Factory Apparel Polyprint Edition is a RIP software that includes numerous options and capabilities, through accessible tools and settings that each of them provides the user with a variety of alternatives. This way the printing outcome is exactly as the one the user had in mind, while the printing procedure becomes easier and at the same time superb print quality is achieved. Colour removal tools are powerful tools that allow the user to remove precise areas or even the whole background of an image. Such a case could be a person standing in front of the scenery, which could save the user from printing unnecessary colours that are incorporated in the design or are quite similar to the substrate’s colour. **Fluid Mask** is a feature included in Polyprint’s software. It allows you to select areas with fine details and colours close to the background. It automatically clears the image by knocking out the selected sections. In order to successfully use the Fluid Mask tool, easily follow the detailed steps below: - Step 1: Upload the file that you want to print, in the desired queue tab. Right-click in the image and select the **Edit with Fluid Mask** option. ![Digital Factory Fluid Mask Step](https://www.amayauk.com/wp-content/uploads/2021/07/Digital-Factory-Fluid-Mask-Step1.jpg) Step 2: In the window that opened, you will notice that your image is now divided into sectors depending on the colour gamut. In the right side, two slide bars are visible named Edge Finding and Edge Blending respectively.   **Edge Finding** Sets how Fluid Mask divides an image into sectors. The higher the setting, the more sectors will appear. When working with fine details, move the slider all the way to the right (More) in order for the number of separated areas to be increased. **Edge Blending** Offers two methods for blending the edges along the cut-out border: **Feather**, which allows simple, even transition across the edge ignoring the character of the edge. **Smart**, uses the characteristics of colour and texture variations around and across an edge. ![Digital Factory Fluid Mask Step](https://www.amayauk.com/wp-content/uploads/2021/07/Digital-Factory-Fluid-Mask-Step2.jpg) **Note**: Smart blending typically produces higher quality results. However, if an edge has low contrast or a lot of noise (extreme colour and texture variations), the edge produced may be uneven. In such circumstances, Feather blending should be used. Step 3: In the left side of the window, 3 brush options are available:   **Keep Local Brush** Fills the sections that you wish to remain in the final cut-out. **Delete Local Brush** Fills the sections that you want removed from the final cut-out. **Blend Local Brush** Fills the sections that will be blended in the final cut-out. Blend Mask lies between those areas you want to keep and those you wish to delete, resulting in a gradual removal. **Note:** The **Brush Size** changes the brush size. The brush cursor is displayed at the centre of your image, while you adjust the size slider so that you can see, exactly, how large your brush will be. The **Brush Strength** determines how far your brush stroke will grow. A Strength of greater than zero may flood-fill into other sectors, similar in colour and texture. The greater the strength, the less similar a sector has to be for it to be filled. - Step 4: Tap on **Images** and select **Auto-Fill with Keep** option, in order for the sectors that you want to keep and therefore print to be selected automatically, after of course you have used the Delete Local Brush tool. - Step 5: When finished formatting your image, select the **Create Cut-out** option, located on the left toolbar, which will apply all your changes to the image and your view automatically will swap from the **Workspace view** to the **Cut-out view,** where you will see the final result. ![Digital Factory Fluid Mask Step](https://www.amayauk.com/wp-content/uploads/2021/07/Digital-Factory-Fluid-Mask-Step3.jpg) Step 6: Tap on **File** and select the **Save and apply** option in order for the new edited image to be saved and appear on your selected queue tab. -
