网点扩大是数字打印中的一个典型问题,它会导致打印的半色调和文本显示得比预期的更暗。对于文本的打印,我们提出了一种对发送到打印机的图像进行预处理的方法,以补偿网点扩大。它基于预测数字图像中给定局部邻域的印刷吸光度的准确模型、惩罚对所需目标文本图像的不保真度的成本函数、以及使用直接二分搜索(DBS)来最小化成本。
Dot gain is a classic problem in digital printing that causes printed halftones and text to appear darker than desired. For printing of text, we propose a method to preprocess the image sent to the printer in order to compensate for dot gain. It is based on an accurate model that predicts the printed absorptance for given local neighborhood in the digital image, a cost function to penalize lack of fidelity to the desired target text image, and the use of direct binary search (DBS) to minimize the cost.
