I want to create a graphic, which consists of multiple, not equal curves [1], that have multiple faults [2]. In the end each color should be a unified area (can be cropped or extended to the document dimensions [3]). The resulting shapes shall in the end be used to mask (not distort) and tint images below (see example). This is done in Affinity Designer (Desktop or iPad) as a aesthetic design (book cover). Sketch of faults across curves

Here is what I came up with yet (colors and images changed):

What I have come up with yet

I tried to divide the areas by creating "cut-line-objects", but this seems to be a lot of copying, deleting of unnecessary by-products and manual shifting of nodes. This process is complex to replicate, if e.g. the curve shapes or fault-angle should be changed. Also this is not exact, and the only way I see is to calculating and positioning each point manually.

Is there an easier, more flexible way, than my described workflow?

  • I don't use Affinity Designer, but in Illustrator/InDesign this could be made quite easily by placing 4 copies of your graphic in 4 separate clipping paths and then shift them. Is this for aesthetic or scientific purposes? – Wolff May 18 at 9:37
  • You say that each color needs to end up as a unified area. That isn't necessarily possible since the curves could be shifted so they don't touch each other anymore. Seems to be happening in your image 3 in the bottom. – Wolff May 18 at 9:43
  • @Wolff Sorry for not clarifying; I want to use the objects as a mask (and filter etc.) for other images grouped below. I updated the sketch and question. For simplicity you can just ignore the purple color. The graphic is a aesthetic design for a book cover and not data driven. – Ahrdie May 18 at 11:05
  • Your question is good, but there are still things that seem unclear to me. Are the curves going to be just an overlay which just affects the colors of images and objects below? Or are the images below supposed to have the same faults as the curves? Are the curves vector shapes or a raster image like in your sketch? I'm asking because I suspect that you are too focused on flattening and snapping everything. It doesn't matter if your graphics have "ragged edges" and sloppiness if those parts of the graphic lies outside the format. – Wolff May 18 at 11:26
  • Thank you for those questions; this has not been clear yet. The curves shall just be an overlay, and not distort the images below (the images should not have the faults). I agree, that it doesn't matter, if the edges are ragged, because they can be scaled away. I have added to my initial question and added an example, I already created. – Ahrdie May 18 at 17:45

I'm not sure that I fully understand your question, but I'll post this as inspiration. I don't mind if you can't accept it as an answer. It's done in InDesign, but the technique should be possible in Affinity Designer.

We start out with a set of vector shapes:

Then we place the images in each of the shapes and apply whatever coloring we want:

Now we regard this as a "finished" group which we want to apply faults/shifting to.

We group the shapes (or, to keep it editable, save it as a separate file and place it in another document) and rotate them (here I rotated 20 degrees):

Now we create 4 rectangles and place a copy of the group inside each one of them:

We can now easily shift the parts up and down to create the faults:

The whole thing is then grouped and rotated back (in this case -20 degrees):

To get rid of the ragged edges we can place the group inside a rectangle (or simply scale it until it exceeds the format):

Hope this helps!

  • I will definitely try your great idea to tilt the whole thing to create the faulted masks. I only see two problems: how do I cut multiple objects in Affinity Designer? Is there a way to reliably unify the cut-out parts after shifting, without generating artifacts? – Ahrdie May 18 at 17:48
  • I'm not sure... I've only tried Affinity Photo and watched videos of Affinity Designer. I don't how these functions perform. You should be able to first somehow intersect the rectangular masks with the curves within and then ungroup everything and join the pieces of each curve using add. – Wolff May 18 at 17:58
  • It worked! I only found a bug, that the intersection had to be done while inside the canvas, otherwise some parts would just disappear. I guess this is the easiest way to achive this. – Ahrdie May 18 at 18:09
