I think the term batik includes a lot of different fabrics. Some are very thickly and closely woven, others are thinner and loose. It's really used more for a style of fabric, so you never know for sure. I've used lots of Hoffman and Moda batiks, and never had this problem. Recently bought some less expensive but lovely batik at Ben Franklins and had to wash, and rinse, and wash and rinse multiple times to stop excessive bleed. It sewed quite normally though. Good luck with your project.
