As set forth herein, computer-implemented methods and systems facilitate employing a single stochastic screen defined up to a specified transition level. The dots at the specified level are connected to form a triangle tessellation with an associated spot function. For up to three colorants, a vector screening technique is employed, which involves a first colorant dot being grown from the vertices, second colorant dot grown from the triangle center, and a third colorant dot grown from the side midpoints. Growth in this manner ensures separation of colorants up to a certain density level. In cases where fourth colorant is to be used at a given pixel, the fourth colorant can be added using methods typically used for clustered screens, such as stochastic screening of the lightest colorant, in order to mitigate color shift sensitivity issues. |
