The mark left on the fabric of your garment is absolutely nothing to worry about. Whilst it's not too common, it'll disappear the first time the garment is washed.
But we understand the concern our customers experience when their samples occasionally arrive with heat-press marks surrounding their print. Is it a fault with the product? With the print method? What if my customer complains about it? They're all valid questions, so let's give you some answers:
The printing method
Everything we print is heat-pressed in some way, including any products printed with dye sublimation. The heat cures the ink with the product, so it's a vital step. Without it, your designs would simply rub off/wash out straight away (for DTG) or wouldn't transfer at all (for dye sublimation and vinyl).
This means it's not a fault, it's simply a side-effect of the printing process. And the reason for it involves pre-treatment, so any dye sublimation or vinyl products, or white garments printed with DTG, will never have heat-press marks since they don't need pre-treating.
DTG printed products need pre-treating. It acts similar to the primer used before painting wood or drywall, stopping the ink being absorbed into the garment and offering a surface for it to adhere to.
The mark occasionally left by the heat-press is basically any excess pre-treatment that has no ink laid on top of it. This excess will wash out straight away, leaving no mark.
If your customer contacts you to ask about the mark on their garment we always advise you explain the above and recommend they wash their garment at 30 degrees, inside out. This will wash out any excess pre-treatment and the mark will disappear.
