Important Information!

Which Formula is right for my Fabric?

We do our best at Six Thirteen Originals to make it simple to find the right transfer product for your fabric type. Our website breaks down each of our ink formulas by fabric type.

Varsity Formula

Our Varsity formula screen printed custom heat transfers are designed to work on most 100% Polyester fabrics. This product features a low melt ink additive which allows the transfer to be applied lower than the standard hot peel transfers. The additive also blocks the fabric dye from “bleeding” into the ink allowing your ink to be bright and opaque on any color.

Varsity screen print transfers are our most versatile product because it can not only apply to 100% Polyester fabric, it can also go on 100% Cotton, 50/50 Blends or Tri-Blend fabrics. We recommend you confirm your fabric type before pressing.

Our Varsity screen print transfer formula is available in our 15¢ single image offer as well as 1 to 3 spot color gang sheets. If you need more than (3) colors, you can also purchase Varsity Formula with Unlimited Colors with our single image or our gang sheet program.

What types of items can you print with Varsity Formula?

  • Moisture wicking shirts
  • Polyester tote bags
  • Canvas tote bag
  • 100% Polyester T Shirts

Stretch Formula

Our Stretch screen print formula heat transfers allow you to print on many performance fabrics including Lycra ® or Spandex ®. You will want to use stretch formula when you have a large logo placed on your garment which may get pulled or stretched when being used.

  • Umbrellas (non coated)
  • Nylon Flags

Nylon Formula

Classic Formula

Our Classic screen print formula heat transfers essentially are screen printed with plastisol ink. There are no additives which can give you a softer feel as compared to our Varsity formula. Classic formula transfers are not recommended for customers who do not have the ability to print with higher pressure settings on their heat press machines. Through many tests, we have discovered that a minimum pressure of 60 PSI (pounds per square inch) is necessary to get a proper application.

We recommend using Hix Heat Press machines or an American made equivalent manufacturer for this product!

What can I print with Classic Formula?

  • 100% Cotton T Shirts
  • 50/50 Cotton / Poly T Shirts

Classic Formula (Unlimited Color)


Vintage Formula

Our Vintage ink formula is designed to give you a soft feel vs any other ink formula. This formula is intended for 100% cotton or 50/50 blends. The inks are less opaque than other formulas, meaning you will see some fabric color coming your logo or artwork. Although we illustrate examples with a "distressed" look, we recommend you follow our minimum art specifications for best results. 

What can I print using Vintage Formula?

• 100% Cotton Jersey Knit T-Shirt Fabric

• 50/50 Cotton/Poly Jersey Knit Fabric
