FORMAT: When printing a design onto fabric using Spoonflower you'll get the best results when you upload a file in TIF format that has been created in (or converted to) LAB color space. You can also upload a JPG or a PNG.
Tip: In Photoshop you can switch to LAB format by going to the Image menu and pulling down to Mode, then checking LAB color. You'll also want to make sure that in the same menu 8 bits/channel is checked rather than 16.
FILE SIZE: Your image can be any size as long as the file is smaller than 25MB.
RESOLUTION: Set up your image at 150 dpi (dots per inch). If you want to design an 8"x8" swatch, for example, you need to upload an image that is 1200 pixels x 1200 pixels.
We will maintain each image uploaded at the size supported by 150 dpi, then tile it to fill the space of the fabric you order. If you upload an image larger than the area of fabric you order, then we will crop it from the lower left corner.
CONFUSED?
If you don't have Photoshop and talking about TIF and LAB color make you anxious, don't worry. You can upload a JPG or other common image format and it will still print nicely. There may be colors in your image that can't be reproduced by pigments on fabric in our printer (very bright colors, absolute blacks, and very saturated colors, for example). If that is the case you will sometimes see all of the colors in an image shift and the colors may end up appearing different from what you expected.
Uploading an image in LAB color offers some protection against all of the colors shifting. In LAB color, if the printer encounters a color it can't reproduce it will shift only that color rather than all the colors.
If you're curious (and technically inclined) you can read more about TIFs here, and more about LAB color here.
