Use your stamps in Affinity
Create a reusable raster stamp brush from your transparent PNG, then choose the colour, size and spacing inside Affinity.
Export your stamp for Affinity
In Stamp Studio, choose Download stamps, select Affinity and download. Save each Affinity PNG separately, or choose an optional ZIP containing the PNGs and these instructions. Only extract a ZIP if you chose that option.
The PNG contains a black stamp with a transparent background. Its opacity becomes the brush coverage, so you can choose your ink colour in Affinity. Keep the transparency: adding a solid background can turn the source into a square stamp.
Open the raster Brushes panel
Open your document and switch to raster painting. In Designer 2 this is Pixel Persona; in the newer Affinity app it is Pixel Studio. Use the Paint Brush Tool and a pixel layer for your test.
Open the Brushes panel and select the category where you want the stamp to live. The panel menu is called Panel Preferences. On iPad, use the equivalent menu in the Brushes panel.
Create a New Intensity Brush
From the Brushes panel menu, choose New Intensity Brush. Select the PNG you downloaded from Vivid, or one of the PNGs extracted from your stamp ZIP. The new brush is added to the selected category.
Use New Intensity Brush when you want to choose your ink colour while painting. New Image Brush uses the image’s own colours and is a different choice. The PNG is a source for creating the brush here; Import Brushes is for a finished brush library such as an .afbrushes file.
Set the spacing and test a tap
On desktop, double-click the new brush to open its settings. On iPad, open the selected brush’s editing options. In General, increase Spacing to separate the impressions in a dragged stroke. Choose a fixed Rotation for an upright motif.
Choose your foreground colour and click or tap once on the pixel layer. Try another colour and a different brush size. For consistent marks, review the Dynamics settings for size, rotation and flow variation. If the mark is too light, check brush opacity, Flow and Accumulation before replacing the PNG.
Name and export your stamp category
Give the brush a clear name and keep related stamps in a custom category. The Brushes panel menu lets you create and rename categories and export them.
Export your finished category as an .afbrushes file for a separate backup or to transfer to another Affinity installation. Keep the Vivid PNG sources alongside it. Test the imported category on the receiving device before relying on it for a project.
If the stamp does not look right
I cannot find the brush after creating it
Check the selected category and that you are viewing raster brushes. In Designer 2, switch to Pixel Persona; the vector brush list is separate.
The file will not load through Import Brushes
Choose New Intensity Brush for the source PNG. Import Brushes expects a finished brush library, rather than the source image supplied by Vivid.
I get a black square or a colour that will not change
Create an Intensity Brush from the transparent PNG exported with the Affinity option. A flattened opaque image can make a square; an Image Brush follows the image’s own colours.
