Embodiment Construction
[0026] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0027] The present invention will be further described below by taking the halftone method to be evaluated as green noise halftone method with hysteresis coefficients of 1.5 and 3.0 respectively, the printer as Pantum2000 laser printer, and the measuring device as Eyeone colorimeter.
[0028] please see figure 1 , the technical scheme adopted in the present invention is: a kind of printer image halftone output algorithm quality evaluation method, it is characterized in that, comprises the following steps:
[0029] Step 1: See figure 2 , this embodiment first designs 20 gray color blocks, wherein, for the gray color blocks, 0 is used to represent black, and 1 is used to represent white, and the gray value increases from 0 to 0.95 with 0.05 as the growth step , paper white is 1.
[0030] Step 2: use the green noise halftone method with a hys...
