DJVU satisfies that requirement perfectly while PDF doesn't. If you don't embed all your fonts into the PDF it will look different on different systems and even if you do: as long as font rendering happens on the target system you will never get 100% pixel perfectly the same output.
- saagarjha 8y agoI haven't use DjVu very much, but as far as I was aware it doesn't store vector data?
- weinzierl 8y agoNo it doesn't but vector data involves rendering on the target system and this leads to unavoidable differences between the output of different rendering systems. DJVU avoids this because it contains bitmaps. If small differences are no problem ePub is an option.
- jsiepkes 8y agoDjVI was specifically designed to contain scanned documents. It was never designed for documents which were digitally authored. Using a rasterized technique is certainly not a good idea in an era where the DPI of screens is increasing. Also since PDF is the standard in the printing industry I think we can safely say the margin of differences is so small they are non existent.
- weinzierl 8y agoAs in ssid, use ePub if you need vector. If you need something that will be displayed the same under any conceivable circumstances, and still will be in many years, consider DJVU. I see DJVU mainly as a viable alternative for archiving, where people usually use PDF/A or TIFF (yes some still archive everything as TIFF).
