How it Works
For a pattern block to seamlessly repeat, sides that are opposite from each other have to match up. Objects that run off one edge of the block have to reappear on the opposite side. When working digitally, objects are matched up by calculating their opposite x and y coordinates.
Left / Right
Increasing the X value moves the object right, decreasing it moves it left.
Up / Down
Increasing the Y value moves the object down, decreasing it moves it up.
- Prepare the Document
- Open Photoshop > File > New Document. For this example, input the width and height of your pattern block to be 1000 pixels (px)
- Match up Artwork
- Place the object onto the pattern block and duplicate its layer
- With the duplicate layer selected click Edit > Free Transform > the X and Y values will appear in the top tool bar
- If you're moving the object down, add 1000px to its Y value.
- If you're moving the object right, add 1000px to its X value
- Program the Pattern
- File > Define Pattern.
- Enter a name and click ok
- Apply the Pattern
- It's best to test your pattern in a new document that's at least twice the size of your pattern block. Once you have a new document > File > Fill > In the Custom Pattern drop down menu, chose your pattern > ok
