Tips for Printing on 50/50 Garments with a DTG Printer  |

After learning how to DTG print on 100% cotton garments, it's now time to learn how to Direct-To-Garment print on 50/50 garments (50% polyester, 50% cotton). Learn the ins and outs from DTG expert Luke Ryerkerk so you can crush your next print job.

Let’s start this off with a good recommendation. At the time of writing this blog, there is not a truly tested and proven ink/pretreatment that can be used to print on 100% polyester dark garments. It CAN be done, but the end result is not retail ready. Because of this, I don’t recommend using DTG on anything above 50% polyester as a good rule of thumb.

The key to printing on 50/50 garments comes in a couple key aspects of pretreat and curing. General settings for your RIP and printer will be very similar to 100% Cotton.

Like all DTG printing, the quality of the garment comes into play. However, because we have 50% polyester in the mix, that can sometimes make up for a lesser quality cotton. This allows us to print on things such as the Gildan DryFit and other cost effective 50/50s that will have pretty good results.

  • Having dye migration or staining issues?
    • Lower press to 330℉ (Some go as low as 300℉ with good results.)
    • Take the amount you would normally spray on the 100% Cotton equivalent and cut it in half.
    • Spray the updated half amount, heat press to cure, spray the half amount again, press to cure and then print.
    • This “double spray” helps against staining and dye migration.
    • Lower your time during this process as well since you’re curing less pretreat. 
      • This will also help against staining and dye migration.
  • What about 50/50 Sweats?
    • You will ALWAYS need more pretreat for sweats. 
      • This can cause more staining and dye migration issues with 50/50 material at times.
    • Double spray with the regular amount of pretreat you use for 100% cotton. (Lower some if you see dye migration or staining)
  • Press in between each spray at 330℉ (Lower to 300℉ if Dye Migration is seen)



  • Most 50/50s shirts will react the same as 100% Ringspun Cotton if pretreated correctly.
  • You may need to lower your white underbase strength a little if too much puddling is experienced. 
  • For Sweats:
    • Double White Underbase is commonly needed for thicker material.
    • Make sure to adjust your platen height before printing.
    • TIP: Use a youth platen when printing on pocket hoodies.


    • The big key here is to avoid dye migration.
    • Final curing is where you’ll see the most dye migration when working with 50/50 apparel.
    • Using a Heat Press?
      • Press in smaller chunks of time.
      • If your ink requires a 30 second hover and 120 seconds of pressing to cure, break the pressing time in 30 to 60 second chunks. (Total time pressed should equal total time required). 
        • Lower times are for garments that experience a higher amount of dye migration.
      • You can also lower your temperature to 300℉ if you’re still experiencing dye migration.
      • Make sure to always do a wash test with new pretreat and cure settings.
    • Using a Conveyor Dryer?
      • Lower the temperature and slow the belt speed compared to the 100% cotton counterpart. 
        • This is if you start to see dye migration or staining.
  • Always make dyer changes in 10% increments when testing.
