Hi julmoral,
Welcome to Affinity Forums :)
You can use Pressure Profiles to create similar effects:
- draw a path with the Pen Tool
- go to the context bar, click on the Stroke width dropdown, set a bigger stroke width if necessary then press the Pressure button on the bottom right of the popup.
- add nodes to the curve or move the end nodes (click on them once to untie them) to manipulate the path's width (see screenshot).
 

Hello, I wanted to ask if anyone knew of a good way to taper vector lines made with the Pen Tool in Affinity Designer. 
 
I know that you can do it on Inkscape and Illustrator, but I haven't figured out a way to do with Affinity. 
Also, I know that I can you the brush tool to get that sort of line with a graphics tablet, but I just want to see if I can do it with the pen tool. 

Here is a link to article of that shows how its done Inkscape so you can get a better idea of what I am asking.

Thank you!

It should be possible using a Gradient Map Adjustment Layer with two colours and then add a Brightness / Contrast Adjustment Layer to get the desired effect. if you need further information, let me know :)

Yes it would be nice for AP to generate REAL duotone, tritone and quadtone (2, 3, and 4 spot colors applied to the same grayscale image via tone mapping curves per each spot color plate.

Very keen to see calligraphic brushes implemented in Affinity Designer! I know this is on the current feature request list, but just giving it a vote, and hoping it will make the next version.
 
I do like the Illustrator implementation, where I can modify the brush by rotating the elliptical stroke profile, and view the calligraphic effect on the stroke live.
 
At the moment, I need to do this in Illustrator, then expand the outline and copy / paste, export / import / open in Designer, and this process invariably makes a bit of a mess of it by adding numerous bezier points.
 
I have experimented with the "Pressure" option in Designer's Stroke palette, but this obviously is not intended to be the same functionality.
 
Thanks!

One thing which could be a great idea is to allow for formulas to position guides.

A blend shape tool would be perfect so you can also make better form following gradients inside an object

Glad we sorted this out …  :)
