About formats

SCT (Scitex Continuous Tone) is a high-end raster image format developed by Scitex Corporation for their prepress and color reproduction systems, with the HandShake format specification dating to 1988. Scitex, an Israeli company founded in 1968, was a pioneer in electronic prepress — their systems were used by major publishers, packaging companies, and advertising agencies to perform color separation, retouching, and page composition for high-quality print production. SCT files store images in CMYK color mode at 8 bits per channel (32 bits per pixel), with the color channels arranged in a band-interleaved-by-line format optimized for the scanline-based processing of Scitex's proprietary hardware. The format uses no compression, prioritizing direct access and processing speed over file size on the dedicated workstations where these files were used. SCT images were typically very large — high-resolution drum scans of transparencies and prints at resolutions of 300 dpi or higher for print-ready output. One advantage is print production heritage: SCT files represent some of the highest-quality digital prepress work of their era, scanned and color-corrected by expert operators on hardware that cost hundreds of thousands of dollars, making them valuable primary sources for reprinting and archival of commercial print work from the 1980s and 1990s. Adobe Photoshop has long supported SCT files for import, and the format can also be read by ImageMagick, XnView, and other tools with prepress format support.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's advanced ebook format introduced in November 2011 alongside the first Kindle Fire tablet. It replaced the older MOBI-based AZW format with a substantially more capable layout engine built on HTML5 and CSS3 subsets, enabling fixed layouts, embedded fonts, SVG graphics, drop caps, and other typographic refinements that were impossible in earlier Kindle formats. Internally, an AZW3 file packages content in a structure derived from EPUB, wrapped in Amazon's proprietary Palm database container with optional DRM protection. The format supports both reflowable text for novels and fixed-layout pages for comics, cookbooks, and children's titles. One major advantage is rich formatting fidelity — publishers can produce visually sophisticated ebooks with complex page designs, nested tables, and precise font control that render consistently across the Kindle ecosystem. Another strength is backward compatibility: AZW3 files can bundle a MOBI fallback section so older Kindle hardware still displays the content, even without full KF8 rendering. The format integrates tightly with Amazon's Kindle platform, supporting features like X-Ray, Whispersync page tracking, and in-book dictionary lookups across millions of devices and apps worldwide.
