摘要： A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.

摘要： Method and system embodiments herein add at least one trap area between abutting objects on an image to be printed by a printing engine. This trap area includes a central region between two outer regions. The method/system establishes a target toner concentration for pixels within the trap area based on toner concentrations of the abutting objects and corrects the target toner concentration to account for irregularities of the outer regions of the trap area to produce a corrected toner concentration for pixels in the trap area. The method/system performs this correction by first empirically testing the printing engine to establish a lookup table of correction values of the outer regions prior to a printing operation. Then, during the printing operation, the method determines a size relationship (weighting) between the central region and the outer regions for the trap area and calculates the corrected toner concentration based on the lookup table and the relationship between the central region and the outer regions. After the corrected toner concentration is calculated, the printing operation can be performed using the corrected toner concentration for the pixels in the trap area.
摘要翻译：本文的方法和系统实施例在由打印引擎打印的图像上的邻接对象之间添加至少一个陷阱区域。该陷阱区域包括两个外部区域之间的中心区域。方法/系统基于邻接物体的调色剂浓度建立陷阱区域内的像素的目标调色剂浓度，并校正目标调色剂浓度以解决陷阱区域的外部区域的不规则性，以产生校正的调色剂浓度陷阱区。该方法/系统通过首先经验地测试打印引擎以在打印操作之前建立外部区域的校正值的查找表来执行该校正。然后，在打印操作期间，该方法确定陷阱区域的中心区域和外部区域之间的尺寸关系（加权），并且基于查找表以及中心区域和外部区域之间的关系来计算校正的调色剂浓度。在计算校正的调色剂浓度之后，可以使用针对捕获区域中的像素的校正调色剂浓度来执行打印操作。

摘要： Disclosed herein is a method that includes a classifier that distinguishes objects based on their color shades. A moving window based operator looks at the color class of the adjacent objects and determines if an adjustment is necessary. If at least one of the objects is the type of interest and the color classes of the objects meet the criteria, then the boundary between the objects is subject to be adjusted. Two adjustment modes are discussed: “adjust-tagging” mode and “adjust-color” mode. In the adjust-tagging mode, a specific tag is sent down to the print engine to force the use of high addressability halftones for the boundary pixels in the darker object. In the adjust-color mode, a color lighter (usually white) than that of the lighter object is assigned to the boundary pixels in the lighter object. The width of the modified pixels along the boundary is configurable.
摘要翻译：本文公开了一种方法，其包括基于其色调来区分对象的分类器。基于移动窗口的操作者查看相邻对象的颜色等级，并确定是否需要进行调整。如果至少有一个对象是感兴趣的类型，并且对象的颜色类别符合标准，则对象之间的边界进行调整。讨论了两种调整模式：“调整标记”模式和“调整颜色”模式。在调整标签模式中，特定的标签被发送到打印引擎，以强制使用高可寻址性半色调用于较暗物体中的边界像素。在调色模式中，较轻物体的边界像素分配比打火机对象更浅的（通常为白色）。沿着边界的修改像素的宽度是可配置的。

摘要： Apparatus are provided, which include a color image processor, an edge distinguisher, and an edge trapping mechanism. The color image processor processes color images, including a given color image. The given color image includes plural color separations each having a set of color values for respective image pixels. The edge distinguisher distinguishes some edges of the given color image as opposing edges. An edge is a transition in the color separation of the given color image from a non-white color intensity value, at one side of the edge, to a white intensity value, at the other side of the edge. A given edge is an opposing edge when a transition of the given edge goes, for a separation of the given color image, in one direction from a non-white color value to a white value, and goes, for another separation of the given color image, in the same direction from a white value to a non-white color value.

摘要： A method of improving edge rendering of objects includes dilation (or contraction) of an object's tag plane by one or more pixels into the surrounding region, with the adjacent tag region having a corresponding contraction (or dilation). The objects of interest (e.g., white text) are first identified; the corresponding object tag plane is then spread or choked, in a fashion analogous to trapping. In the case of negative text on a tint background, by expanding the tag plane for the negative text object, the text hint would be forced one pixel into the tint object plane everywhere along the perimeter of the negative text. This could then enable greatly improved negative text rendering.

摘要： Disclosed herein is an image processing method for producing enhanced halftone edges, particularly suited to those edges which only lie upon the background as apposed to those edges which abut other halftone screens. It utilizes a step of defining border pixels and a step of halftoning those border pixels in a different manner than the halftoning applied to the interior region of the tint or image segment. The preferred halftone for the border pixels will be related to the interior halftone by some number of common spatial frequency harmonics. Examples of common-harmonic screening for an edge include, but are not limited to: (a) same screen with different tone reproduction characteristics (boosted edge values); (b) same screen angles and frequencies with a different spot function, possibly phase shifted; (c) a dot screen whose frequency vectors can be generated by the frequency vectors of the interior screen; (d) a line screen whose frequency vectors can be generated by the frequency vectors of the interior screen. This generation process is directed to ensuring that the two screens will be “harmonically matched” where at least one of the fundamental frequency vectors and harmonics of the first screen will equal at least one of the fundamental frequency vectors and harmonics of the second screen.
摘要翻译：本文公开了一种用于生产增强的半色调边缘的图像处理方法，特别适合于仅靠在与其它半色调屏幕相邻的那些边缘上的背景的那些边缘。它利用定义边框像素的步骤和以与应用于色调或图像片段的内部区域的半色调不同的方式对这些边界像素进行半色调的步骤。边框像素的优选半色调将通过一些数量的共同空间频率谐波与内部半色调相关。用于边缘的共谐波筛选的示例包括但不限于：（a）具有不同色调再现特性（增强边缘值）的相同屏幕; （b）具有不同光点功能的相同屏幕角度和频率，可能相移; （c）可以通过内部画面的频率矢量生成频率矢量的点画面; （d）可以通过内部画面的频率矢量生成其频率矢量的行画面。该生成处理旨在确保两个屏幕将被“谐波匹配”，其中基本频率矢量和第一屏幕的谐波中的至少一个将等于第二屏幕的基本频率矢量和谐波中的至少一个。

摘要： A method for smooth trapping of a small graphical object, includes receiving from a trap generator the location of a trap pixel in a small object that should be changed in color; determining the width of the small object containing the trap pixel; comparing the width of the thin object with a trap threshold width; if the width of the thin object is less than the trap threshold width, adjusting the hue of the trap pixel according to a predetermined relationship; and applying a trap correction to the trap pixel according to the adjusted trap hue. The predetermined relationship may be a linear relationship that interpolates the trap hue monotonically (from the original trap hue to the original object hue) for object widths less than the trap threshold width. The method may be applied to small objects and small font text objects.
