Resolution Enhancement Technology is a form of image processing technology used to manipulate dot characteristics popular among laser printer and inkjet printer manufacturers. Resolution Enhancement Technology is also a closely related technique used in VLSI photolithography manufacturing technology, in particular in the 90 nanometer technology.

Resolution refers to the sharpness of image detail, smoothness of curved lines, and the faithful reproduction of an image. In both cases, RET uses pre-compensation of the image in order to try to mitigate the effects of the printing process.

Among the major issues in RET in VLSI technology are the fundamental properties of a wave: amplitude, phase, and direction.
