AI Technical Summary
Existing methods fail to convert old LEN files, which were RIPped for lower image resolutions, into a format compatible with newer imagers that require higher resolutions, and do not support conversion of monochrome TIFF or LEN bitmap files into vector PDF files for modern flexographic printing workflows.
A method and system for converting monochrome LEN or TIFF bitmap files into a vector PDF format, utilizing an AI-supported database search engine platform and raster image processor libraries to identify tonal values and screen dots, and incorporating dot gain compensation algorithms to adapt the files for higher resolutions and screening types.
Enables the conversion of old LEN files into a format suitable for modern imagers, reducing storage needs and facilitating flexible processing across different devices, while maintaining image quality and compatibility with new screening technologies.
