I saw a lot of font designs like this, but haven't found any tutorials on how to create such a font. How can I create a font like this?
This is specifically for Adobe Illustrator, but the principle will apply to any package...
First, you need to draw the letter shapes with lines. It will probably help to work on a grid for this step. (I have shown the 'exploded' view just so that you can see the individual lines, that's not a step in the process.)
Next, increase the thickness of the lines to something that you like the look of and change the 'End Caps' to rounded (middle button, top row, directly underneath the line weight. Finally, choose your colours and then set the blending mode of the lines to 'darken' or 'multiply' (or experiment with other blending modes). Done.
Ok so in order to design this you might want to have the font used in that design but I will show you how to create the overlapping effect you see in that image. You might want to draw this over the text where you want to use this.
So design tall rectangles and the select them with your white arrow (a) and a small dot will appear next to each corner of the objects box.
Simply using the same white arrow tool drag one of these dots so you can see the corners become totally round.
Do this to all your rectangles. Then select them and make tem overlap
After this choose your Transparency menu on the side bar or add it by going to top menu "Window > Transparency". From the drop down menu choose Multiply.
Then to enhance the effect you can change the objects' opacity also.
Note that some colours will work better than others.
Hope this was useful to you.
