Here is why the **Anycubic Photon Mono 4** specifically is well-suited for this task:
**1. Extremely High Resolution (10K Screen)**
The standout feature of this printer is the **10K (9024 x 5120)** resolution on a 7-inch screen.
The standout feature of this printer is the **10K (9024 x 5120)** resolution with a pixel size of 17µm (0.017mm) on a 7-inch screen.
* **Why it helps:** In PCB fabrication, resolution dictates how thin your traces can be. A 10K screen provides an exceptionally small pixel pitch. To put this in perspective, this is equivalent to a print resolution of approximately **1500 DPI**.
* *Calculation: The screen width is 153.4mm (6.04 inches). 9024 pixels / 6.04 inches ≈ 1494 DPI.*
* This allows you to expose traces for fine-pitch SMD components (like TQFP or 0402 packages) with professional-grade sharpness, far exceeding what is possible with inkjet or laser-printed transparencies.

1. Open your PCB project in the KiCad PCB Editor.
2. Go to **File -> Plot** and select `Plot format` as `SVG` and set the `Output directory`.
3. In the `Include Layers` section select one layer (e.g. `F.Cu`, `F.Mask` or `F.Silkscreen`). If you select multiple layers they will be ploted as separate files.
4. Optionaly, select additional layer(s) e.g. `Edge.Cuts` in the `Plot on All Layers` section. This way you can merge layers (e.g. front copper layer with board outset) into a single svg file.
5. Click **Plot** and **Close**.
3. In the `Include Layers` section select layers `B.Cu`, `B.Mask` and `F.Silkscreen`. Each layer will be ploted as a separate SVG file.
4. Optionaly, select additional layer(s) e.g. `Edge.Cuts` in the `Plot on All Layers` section. This way you can merge layers i.e. add board outset into each file generated.
5. Click **Plot** and **Close**.
