What is the difference between .sk1 and .g4?

Description: 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.; Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
