Record the sample before washing
Note the product code, shade, size and decoration settings. Photograph the finished sample and measure chest width and body length laid flat. Keep an unwashed sample as a reference when possible.
Follow the finished garment’s care instructions
Use a wash and dry process that the garment and decoration both support. Record cycle, temperature and drying method. After drying, repeat the measurements in the same positions and compare both samples under the same light.
Check what changed
Look for transfer edges lifting, print cracking, colour transfer, seam twisting, embroidery puckering and uncomfortable backing. If an issue appears, change one variable at a time and record the next result. Keep the approved sample with the order notes.
