Why look for a Rasterbator alternative?
Rasterbator is great at one specific thing: the dotted, pop-art halftone look. But it always converts your image into dots. If you want your photo, map, blueprint, or stencil printed as it is — crisp and true to the original — you need a tiler that preserves detail. GridPrint splits the full-resolution image across your printer’s pages, so what you assemble looks like your picture, not a dot pattern.
