Before you can print your design to your transfer paper, always make sure you test it by simply printing it on a regular piece of paper.
Transfer papers are costly, and you don’t want to waste your cash. Printing a preview is critical in that it helps you check if your design will appear within the margins, whether the colors print correctly, and of course, it gives you an idea of how your artwork looks when printed on paper.
Before printing on a tee, you can also consider testing your transfer paper on an old garment. Again, this will give you an idea of how your end product will look like after printing.
One More Tip: Before placing your garment on a heat press machine for printing, always make a point of stretching it. This helps prevent your prints from cracking.
