Block Printing on Fabric vs. Paper: What You Need to Know
Share

Choosing the Right Fabric
Paper and fabric absorb ink differently. Paper is a smooth surface that is generally easier to achieve consistent prints and capture details from carved blocks. Fabric on the other hand is flexible and textured so the surface might shift slightly while printing and requires a bit more intention. With that being said, the type of fabric is key in achieving attractive results.
The best fabrics for block printing are natural fibers with smooth, tight weaves, such as cotton or linen (such as cotton shirts, linen pants, a denim jacket, a canvas tote bag). These fabrics absorb ink more evenly and capture cleaner details than loose, stretchy, or fuzzy materials like knit or wool.
Choosing the Right Ink
Generally speaking, one of the big differences between printing on paper and fabric is the type of ink you use. For paper, relief printing inks are designed to sit nicely on the surface while capturing details. For fabric, you'll want a fabric ink that's made to bond with fibers and stand up to washing. Also, many fabric inks need to be heat-set with an iron after they've dried. This helps bond the ink to the fibers so it stands up better to washing.
Although oil-based inks for block printing are not intended to be used for fabric, I've found they can work surprisingly well on projects that won't be washed often, like tote bags or wall decor.
Water-based inks for block printing do not work on fabric as they'll wash out after being reactivated with water.
Tips for Better Fabric Prints
Details
Because fabric is flexible, it's harder to transfer fine details when printing from block to fabric as opposed to paper. Because of that, bold shapes and simple designs usually print best on fabric.
Pressure
Whether you're printing on paper or fabric, even pressure is necessary for even transfer. Fabric generally requires a little more pressure than paper so the ink absorbs into the fibers, but pressing too hard can cause the design to blur. Which brings me to my next point, testing.
Testing
Before printing your final project, make a few test prints on scrap fabric. A quick test can help you dial in the amount of ink to use, how much pressure to apply, and see how details come out.
