Guidelines for constructing patterns
Follow these general guidelines for constructing pattern tiles: - As you create your pattern tile, zoom in on the artwork to align elements more accurately, and then zoom out from the artwork for the final selection.
- For greatest efficiency in previewing and printing, a fill pattern tile should be about 1/2 inch to 1 inch square. Side tiles for brush patterns should be no larger than 1/2 inch to 1 inch high by 1 inch to 2 inches wide; the corner tiles must be the same height as the side tiles and should be square.
- The more complex the pattern, the smaller the selection used to create it should be; however, the smaller the selection (and the pattern tile it creates), the more copies are needed to create the pattern. Thus, a 1-inch-square tile is more efficient than a 1/4-inch-square tile. If you are creating a simple pattern, you can include multiple copies of the object within the selection intended for the pattern tile.
- To create simple line patterns, layer stroked lines of varying widths and colors and place an unfilled and unstroked bounding box behind the lines to create a pattern tile.
- To make an organic or textural pattern appear irregular, vary the tile artwork subtly, not dramatically, for a more realistic effect. You can use the Roughen filter in the Distort menu to control variations.
- To ensure smooth tiling, close paths before defining the pattern.
- Enlarge your artwork view, and check for flaws before defining a pattern.
- If you draw a bounding box around the artwork, make sure that the box is a rectangle, that it is the backmost object of the tile, and that it is unfilled and unstroked. To have Illustrator use this bounding box for a brush pattern, do not fill or stroke the box and make sure that nothing protrudes from it.
Follow these additional guidelines when creating brush patterns: - When possible, confine artwork to an unpainted bounding box so that you can control how the pattern tiles. (See How patterns tile.)
- Corner tiles must be square and have the same height as side tiles to align properly on the path. If you plan to use corner tiles with your brush pattern, align objects in the corner tiles horizontally with objects in the side tiles so that the patterns tile correctly.
- Create special corner effects for brush patterns using corner tiles.
