The CH file format, associated with SciTex Continuous Tone images, is a specialized file type used primarily within the professional printing and graphic design industries. It is designed to store high-resolution, continuous-tone images that are ideal for high-quality print production, ensuring accurate color representation and detail. CH files support a wide color gamut and precise pixel control, making them suitable for complex graphics and photographic images. This format is typically used in workflows that require the highest image fidelity for print media, such as magazines, brochures, and packaging.
Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
