Sažetak
Use of typographic characters as screening elements is presented herewith. Each pixel of the picture is replaced with a letter character that corresponds with it as to coverage value. All letter characters that make up an alphabet are used. The overall picture can be screened with a single letter character or with many different elements. Quality screening is achieved with characters that have undergone measuring of the screening cell coverage, i.e. the quadrant where they are positioned. Continuous coverage increase within one and the same font is achieved in several iterations. There are no automatic possibilities, so corrections are carried out manually in programs for producing fonts. Characters that replace the screening elements depend on the graphic content that they reproduce. Generally known fonts are used for screening, as well as those found in the author's own font collection, providing thus for the uniqueness and originality of the reproduced pictures. Design possibilities are uncountable, especially if pictograms are used as screening elements.
