Art paper refers to a type of high-quality, smooth paper that is especially suited for copperplate printing, a form of intaglio printmaking. The term copperplate originally comes from the technique of engraving or etching designs onto a copper plate, which is then inked and pressed onto paper to create a print. This method was widely used for fine art prints, maps, and book illustrations from the 16th century onwards.
Art paper is characterized by its smooth surface, which is necessary to capture the fine details of the engraved or etched designs without smudging or bleeding. This quality makes it ideal not only for traditional copperplate printing but also for modern uses such as calligraphy and professional stationery. The smoothness allows for crisp lines and fine detail, which are essential in calligraphy, particularly in styles like Spencerian or Copperplate script that require precise strokes and pressure control.
In addition to its smooth texture, copperplate paper is typically heavier and more durable than regular paper, providing a sturdy base that can handle the pressure of the printing process without tearing or warping. It may also have a slightly glossy finish to enhance the appearance of the printed images or text.
While traditional copperplate printing is less common today, replaced by more modern printing techniques, copperplate paper remains popular among calligraphers and artists who appreciate its quality and the crisp results it can produce.
