Relief or planographic? Line engraving or drypoint? Lithography, but which: chalk or crayon? Three or four colour halftone? Or is it simply laser or inkjet printed? Identifying image reproduction and printing processes can be difficult, especially if you are looking at documents printed in the nineteenth century or later. And if the identification of historical, or even modern processes is often difficult for the staff of printing museums used to handling such material, it is generally a closed book for the average visitor.

Hildegard Homburger, who gives courses on the identification of printing processes in collaboration with the International Association of Book and Paper Conservators (IADA), has produced two illustrated A1 format posters showing enlarged details of the more commonly encountered processes.


Available in either English or German, the posters are an invaluable quick reference and teaching tool for printing museums.

They can be ordered either rolled or fanfolded. The folded version can be easily used on-site for the identification of prints.
