When converting from RGB to CMYK for printing, especially in DTF (Direct to Film) printing, slight shifts in color can occur. This is because the RGB color gamut (the range of colors) is broader than CMYK, meaning certain vibrant RGB colors may not have an exact match in CMYK, leading to a duller or different color appearance in print. Colors may vary slightly when converting from RGB (screen) to CMYK (print)

A:The t-shirts are a jersey knit, so they have a super soft cotton feel. However they do have moisture wicking and anti-microbial properties like a dri-FIT tee.
Q:How do you sublimate on black? I know it says 100% polyester, but I have never been able to sublimate on black?
Asked by: Tricia - 07/04/2023
A:Here are a few options you can attempt to do:
Use a white base layer: One method is to apply a white base layer on the black fabric before sublimating your design. This white layer acts as a foundation and allows the colors to appear more vibrant. You
A:If you are looking for Gildan options with pockets the Gildan 530 (G530) and Gildan 830 (G830) both have pockets. Check out the blogs for more information on pocket tees.
Q:Is this shirt good for screen printing and if I order my printing through you what type of printing would it be? Also, if I provide artwork, can you size it to fit the shirt properly?
Asked by: Keith - 08/09/2025

Print vs Embroidery — what’s the difference?
Print (DTF)
✔ Unlimited colors
✔ Great for photos & detailed designs
✔ Bold, vibrant graphics
Embroidery
✔ Raised stitched look
✔ Best for simple logos/text
✔ More professional & upscale feel
Quick tip:
Colorful or detailed = Print
Clean logo or branding = Embroidery
What is Expert Sizing?
We automatically size your design based on the garment and placement so it looks balanced and professional. Perfect if you’re unsure what size to choose.
Why do printed colors look different than my screen?
Screens use RGB. Printing uses CMYK. Some colors may appear slightly different in real life — this is normal in professional printing.
What files work best?
PNG (transparent), AI, PDF, or high-res JPG.
Cleaner files = better results.
Can I embroider detailed artwork?
Embroidery works best with simple designs. Small text or complex graphics may need to be simplified — otherwise we’ll recommend Print.
Shoulder Measured straight across from one shoulder seam to the opposite shoulder seam.
Chest Measured straight across from one underarm seam to the other (pit-to-pit).
Body Length Measured vertically from the top center to the bottom edge on the back side, as the back is slightly longer.
Sleeve Length Measured from the top edge of the sleeve straight down to the bottom edge.
