Need some help preparing your artwork in Adobe Illustrator? Know how to prepare a gang sheet? Rick from 613 Originals shows you how to prepare artwork for our Single Image and Gang Sheet programs. Our heat transfers are screen printed with plastisol ink and require the use of a commercial heat press that can produce temperature ranges of 270°F- 375°F and HEAVY pressure (40-60PSI). Not for use with a home iron or Cricut® Easy Press.
