How to create this kinda halftone circle in Inkscape


Question

I'm trying to create this halftone effect in Inkscape but I'm not able to produce it. All I'm able to do is create a small circle and clone it to produce simple halftone. But how do I do this?

To quickly create the desired image we can use the Clone > Create Tiled Clones... tool.

Here is the steps involved (in Symmetry: P1: simple translation mode):

  1. Draw a circle of desired size (e.g. 400 px)
  2. Set fill to nothing
  3. Set Stroke

    • Paint to fully transparent (here I used light blue for demonstration
    • Style to Mid Marker DotL (dot size depends on stroke width!)

    enter image description here

  4. Choose Clone > Create tiled clone with the following settings:

    • Rows, Columns 1 x 10 (for 10 clones)
    • Shift x: -100% (to keep clones centered)
    • Rotation per columns 10°

    enter image description here

  5. Select all or create a group.

  6. Choose Clone > Create tiled clone with the following settings:

    • Rows, Columns 1 x 10
    • Shift x: -100%
    • Scale X (per column): -10%
    • Scale Y (per column): -10%

    enter image description here

By choosing different settings we may change number or color of dots, rotation, or introduce a fade effect if needed.

  • For changing colors of the dots we have to apply Extensions > Modify Path > Color Markers to match Stroke in step 1. above before we make the stroke transparent.

  • Additionally in the next example a Fade Out of 10 % in Blur & Opacity and a rotation of 5° was added when creating the clones in step 6.
