Furthermore, the expense of the high-quality paper and photogravure quality printing, needed for the colour pages and photo features, pushed the cover price up.
The refining of photogravure methods, and then the introduction of halftone reproduction around 1890 made low cost mass-reproduction in newspapers, magazines and books possible.
Because of its high quality and richness, photogravure was used for both original fine art prints and for photo-reproduction of works from other media such as paintings.
