There are a number of services online that will take a digital design and print small lengths of fabric. Unlike the big print houses they provide a service for small runs and do not have expensive set up costs that make it prohibitive for a studio based textile practitioner to use.
Many people know of Spoonflower and Karma Kraft ( added later – Karma Kraft are no longer in business) but did you know about Fabric on Demand? Each service offers a slightly different product and it is sometimes hard to compare what is what.
Kim of True Up performed a Digital Fabric Printing Experiment and sent digital files to each and compared the printed results.
You will find a comprehensive illustrated comparison of print colour and quality on her blog alongside a very useful spreadsheet of the results of her research which Kim is giving away as PDF file on her website.
