What is the difference between .art and .sk1?

Description: PFS Art Publisher Image (ART) is a raster graphics file format used for storing digital images. It was developed by Progressive Networks for use in their Progressive FreeStyle Art Publisher software. ART files are compressed using the run-length encoding (RLE) algorithm, which allows them to store large images in a relatively small file size. The ART format supports up to 24-bit color and is often used for storing digital photos and other images.; An SK1 vector graphic file is a file format primarily used by the sK1 illustration program, which focuses on providing professional-quality design features for prepress processing. Unlike other vector formats, the SK1 file format is unique for its support of CMYK color, which is crucial for color accuracy in printing. It also includes advanced features such as color profiles and spot colors, making it particularly suitable for tasks that require precise color matching and high-quality print outputs.
