The advantage is that it has strong weather resistance, that is, it can be waterproof and sunproof, and will not fade or change color when placed outdoors for a long time. The disadvantage is that the quality of inkjet is poor; the photo machine is mainly used for the production of indoor inkjet products such as indoor stickers, display boards, posters, posters, and regulations. The quality of inkjet printing is relatively high.

The photo machine uses water-based ink. No smell, not waterproof, need to be coated.

Output medium: The output medium of the inkjet printer is usually on the inkjet cloth, car stickers and other media whose surface is PVC material. The output medium of the photo machine is photo paper backing PP and spraying pictures.
