摘要： A structure of bands is associated with printhead-array image-forming elements, forming a printmask. Some band pairs are complementary. A low usage percent is stated for at least one band and a like value for another, a complement to each “at least one” band, to smooth the mask and image. The invention best sets a number N of passes, a wavenumber multiplier M for the image, and overall number B of bands N×M×2, the “2” accounting for odd and even elements; bands appear in order: first group of M bands, odd and even, second group of M bands, odd and even, . . . (N−1)th group of M bands, odd and even, Nth group of M bands, odd and even. In another novel aspect the invention has programming for creating a geometrical structure of bands, respectively associated with the image-forming elements and constituting the printmask. The invention also has programming for specifying a relatively low usage percentage for at least one particular band that is associated with image-forming elements that are not at either of the ends of the array; and programming for applying the printmask in said printing.

摘要： One invention form is a method using all input data for one or preferably plural colorants, one time to control colorant deposition in forming a pixel array on a printing medium, and at least one other time to control deposition of more of the same colorants. At least one “applying” includes choosing data-array pixels to deposit added colorant. The two data-usage times can be associated directly with depositing colorant in respective printer passes; or may be done at (or near) rendition, sending output data to printmasking for pass allocation. Selection preferably includes setting maximum density on the medium—and choosing locations for that density, best by analyzing data to find locally dense areas, e. g. counting neighboring pixels. Selecting also includes defining locations to receive particular density, and creating additional density levels based on densities in the data array. Another method form includes defining an augmentation array and applying it to control part of colorant deposition. Preferably also included is applying the original array to control other deposition of colorant. Applying the augmentation array preferably increases colorant deposition, relative to applying the original array, by less than 100% with non-linear response to data.
摘要翻译：一种发明形式是使用一种或优选多种着色剂的所有输入数据的方法，一次在打印介质上形成像素阵列时控制着色剂沉积，以及至少另外一个时间来控制更多相同着色剂的沉积。至少一个“应用”包括选择数据阵列像素以沉积添加的着色剂。两个数据使用时间可以直接与相应打印机通行证中的着色剂相关联; 或者可以在（或接近）再现时完成，将输出数据发送到打印掩码以进行通过分配。选择最好包括设置介质上的最大密度，以及通过分析数据找到局部密集区域，最佳地选择该密度的位置， G。计数相邻像素。选择还包括定义位置以接收特定的密度，并且基于数据阵列中的密度创建额外的密度水平。另一种方法形式包括定义增强阵列并应用它来控制着色剂沉积的一部分。优选还包括应用原始阵列以控制着色剂的其它沉积。应用增强阵列优选地相对于应用原始阵列将着色剂沉积增加小于100％，对数据进行非线性响应。
