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.

Initial release: 1988
SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.
