The format of the trademark pattern file should be jpg, the graphics should be clear, the size of the pattern file should be less than 2KB, and the graphics pixels should be between "4× 4" and "15× 15". If the trademark pattern is obtained through scanning, the graphics that conform to trademark laws and regulations should be scanned in 24-bit color, RGB format and 3dpi resolution (the graphics are clear, larger than 5×5 cm and smaller than 1×1 cm). The applicant (or agent) shall ensure that the color depth (or gray scale) of the scanned graphic is consistent with that of the original graphic, otherwise, the clarity of the graphic on the Trademark Registration Certificate may be affected.
if you apply for trademark registration with a three-dimensional logo, you should submit a drawing that can determine the three-dimensional shape and should include at least three views.
if you apply for trademark registration with color combinations or colored patterns, you should upload colored patterns and black-and-white drafts respectively. If no color is specified, a black and white pattern should be uploaded.
if it is a paper document application, the application pattern size is between 5x5cm and 1X1. I hope I can help you to adopt it.
