TIFF (Tagged Image File Format) is considered the best choice for printing high-quality images.

TIFF is a lossless, uncompressed format that retains all the details and colors of an image without any degradation. This makes it ideal for professional printing, especially if you are dealing with photographs or graphics that demand the highest image fidelity.

Unlike JPEG, which is a lossy format and can introduce compression artifacts, TIFF preserves the original data, ensuring a true representation of the image.

Additionally, TIFF supports layers which is compatible with both CMYK and RGB color spaces, making it versatile for various printing processes.
