How to prepare a seamless pattern for fabric printing?
A seamless pattern to print on the fabric will allow you to create unique sewing textiles. To design a seamless pattern, you can use any graphics processing software, such as Adobe Photoshop, Adobe Illustrator, Clip Studio Paint, Procreate etc. You can create a pattern based on a scanned drawing or create it from scratch in graphics software.
Start by drawing or designing all elements of your pattern so that they are visible on the canvas and do not go beyond any of its edges. Draw each element on a separate layer. Then, the finished shapes, which will be the basis of your pattern, have to be arranged on the canvas.
Pick one of the side edges and plan which elements should go beyond it. These will be the so-called boundary elements. Copy the layer with the element that falls outside the border of the canvas, reposition it on the X-axis (horizontal) and change the entire width of the canvas (expressed in pixels or centimetres, depending on your settings), for example by 1200 pixels. Repeat this for all elements on the side edge of the pattern. This way, you will create a border pattern for the left and right edge of the seamless pattern, thanks to which you will be able to duplicate and arrange this small section of the design, and the pattern will blend in perfectly. Repeat the same for the elements on the Y-axis (vertical). Copy and move the elements extending beyond the top (or bottom) edge of your canvas by the entire height of your canvas (for example 1200 pixels).
Do you want to see if your design connects seamlessly before you send it to print?
If you are using Photoshop, open the Edit menu and select Define Pattern. Save your design under any name and then create a new file that is larger than your original design (in our case, we will create a file that is 4,800×4,800 pixels). In the new file, create a layer and fill it with a uniform colour using the paint bucket tool. Right click on the layer and open the drop-down menu. Click Blending Options and then Pattern Overlay. Select your pattern from the list and see if all elements combine well.
