DK-Aquatint Screens give extremely fine and delicate grey tones, together with deep blacks. The screens have been defined by the photographer Henri Bøegh for working with photographic transparencies and hand drawing and wash transparencies.
Aquatint screens, sometimes referred to as Stochastic screens, are used to convert continuous-tone images to discontinuous-tone images on photopolymer films and plates such as Toyobo. They do this by exposing the body of the film to a random dot pattern, simulating a rosin aquatint, prior to exposing the image. This creates a structure within the film that will capture all the delicate tones and deepest blacks that exist within the image. After exposing the polymer film to the aquatint screen, you then expose it to your image in the form of a positive transparency.
DK-Aquatint Screens have an 80% density with opaque random dots of 60 microns (resolution 2400/175 lines)
Always handle an aquatint screen carefully by the edges and clean gently with soap and water or rubbing alcohol, as needed.
For best results, conduct step tests of varying exposure times for your Aquatint Screen on any exposure unit.
This is a Danish DK-Aquatint Screen measuring 320 x 440mm, A3+.
