Digital printing is by far one of the most exciting developments in the textile industry. Not only does it open up endless opportunities for customization, small run printing, prototyping and experimentation but it also puts textile printing within the budget of your average illustrator.
Digital textile printing can reproduce unlimited colors and shades but - as with most forms of printing - what you see on screen is not necessarily what you get back.
How to design your printing pattern?
stpe 1 Textile design with Photoshop and Illustrator
Choose File > New to create a document.
Note: If you intend to have your pattern printed as a textile, choose a manageable dimension for a tile, such as 4 x 4 inches, and set the Resolution to 300 pixels / inch. Choose CMYK color for the Color Mode and press OK.
Start by finding an interesting image that would work as a repeating pattern. If you want to recreate a textile like Leah Rama's find a classical portrait. You can find lots of open access portraits at NGA Images.
Copy and paste or File > Place the image you've chosen onto your canvas.
stpe2 Cut out part of the image
Click the Quick Selection tool in your toolbar and drag over the area of the image you want to cut out. Hold down the Option/Alt key to subtract from your selection.
Choose Select > Refine Edge and manipulate the Adjust Edge controls to clean up your selection. Click OK.
Finally, click Add Layer Mask in the Layers panel to isolate the selection from the rest of the image and make the background transparent.
stpe3.Adjust colors and apply filters
Choose Layer > New Adjustment Layer > Hue / Saturation, and then click OK. Adjust the settings in the Hue/Saturation panel to brighten the colors.
You can also apply other adjustments to get the effect you want. For instance you can apply the Filter > Pixelate > Mosaic to get a pixelated look. Make sure you select the image thumbnail in the Layers panel before applying filters.
Stpe 5.Save artwork to your Creative Cloud Library
Now that you have artwork, you can save it as a graphic to your Creative Cloud Libraries and use it in Illustrator to create a pattern.
Choose Windows > Library. Then Select all visible layers in your Layers panel. In the Libraries panel, click Add Graphic. A new graphic thumbnail appears in your libary.
Tip: Repeat steps 2-5 any number of times to create a wide variety of graphics to use in your pattern.
