Can PS be used to design the outer packaging (beverage bottle)? I need it when I apply for a patent.

The design of bottle stickers doesn't need photos, just print out your design directly. There is no need to process bottles, because bottle stickers are graphic designs. Oh! ! You can use PS software. That software is really great, its function is to superimpose pictures together, and you can also modify and add effects to a single layer. I learned to write the date! Not bad! Advertising and graphic design are more than enough! ! Just make a plan with PS and print photos. It's only a few dollars. If you design for an advertising company, they will charge you. It is generally acceptable to find a print shop for such a small job, or design art students at school can apply for a patent. I suggest you consult a professional. If it is a three-dimensional design, PS is not enough. You need 3D software.
