Note: A reproductive process used primarily for photographs from the 1880s to the 1950s, utilizing small dots of variable size in relief to reproduce tone in the prints. The process involves re-photographing a photograph through a ruled screen, which creates a negative image made of dots of variable size. A relief halftone block is prepared by printing the negative face down on a copper plate coated with fish glue or bichromated gelatin. The unexposed areas remain soluble after development and are washed away; then the plate is acid etched and used in a printing press. From the end of the 19th century onwards, halftone was the principal means of reproducing photographs in printer's ink where long print runs are required and high quality is not of paramount importance. The principle was first suggested by William Henry Fox Talbot in 1852; it was developed commercially in the 1880s.

Additional Notes: |
|
| Chinese (traditional) ..... 1880年代至1950年代之間，主要運用於攝影的複製技術，藉由凸版上各種大小不同的網點，在印刷品中複印出色調。此一技法是透過有格線的網版來重攝照片，形成由各種大小不同的網點所構成的負片圖像。製作網目凸版刻版的過程，是在塗上魚膠或重鉻酸鹽明膠的銅版上，將負片面朝下印刷而成的。未經曝光的區域經過沖印後仍具有可溶性，並且會被沖洗掉。接著，將印版以酸蝕刻，並置於印刷機上。自十九世紀末開始，網版印刷成為印刷油墨複製照片的主要方式，在需要龐大印量而高品質非重要考量的印刷中廣為運用。此一原理最初是由威廉‧亨利‧福克斯‧塔伯特(William Henry Fox Talbot)於1852年所提出，在1880年代發展成商業用途。 |
| Dutch ..... Fotomechanisch procédé waarbij de afbeelding met behulp van een raster wordt verdeeld in een regelmatig patroon van stippen van verschillende omvang; daarna wordt de plaat geëtst, waarbij de stippen in reliëf achterblijven. |
| Spanish ..... Proceso fotomecánico en el cual la imagen es dividida en un diseño regular de puntos de diferentes tamaños utilizando una malla. Luego la placa es grabada, dejando los puntos en relieve. |
