 Designing the artwork to allow for a gap at the seam of the seat of the pants helps greatly. This is easy to do if you are printing lettering only. Use a smaller squeegee and stroke down the left side and right side of the sweatpant separately. Trying to print directly over the seam may cause some off contact problems.
If your artwork does not lend itself to being separated to both sides of the pant seam and you have to print over the seam, use a lower mesh count screen. If you have off contact problems, try using some shims under the left and right sides of the pant or making several passes with your squeegee. Hot split or cold peel transfers also work well over the seat because of the pressure applied from the heat press. Have a question about screen printing or t-shirt printing? Ask ASPA! -- Get Answers.

 You are experiencing “sizing burn-off." When flash curing,
unpleasant fumes are often released into the work area from the shirt during the heating process. Most shirts are treated with “sizing” agents to increase the weight, crispness, and luster of the shirt. When heat from the flash unit is applied to the shirt, these sizing agents begin to “burn off,” creating a characteristic odor. When you first experience this, you will most likely become alarmed thinking that the shirt is “burning up,” but it is only the sizing being eliminated from the shirt. The best way to control this problem is to keep a fan operating nearby to blow the sizing fumes away from the work area. The sizing burn-off problem will be most apparent when flashing fleece (sweatshirts, sweatpants), and certain colors of dark shirts, e.g. (forest green and royal blue shirts).
