Abstract: Techniques are provided that include an algorithm and a computing device using such algorithm to compute a white ink separation channel from the CMYK or RGB data from a print pipeline as an input. This input originally corresponds to print data on a media with standard whiteness, e.g. standard whiteness corresponding to a diffuser used by the Comission Internationale de l'Eclairage (CIE) 1964 media whiteness formula. In an example implementation, the white ink channel computed by the computing device using such algorithm may be printed as a pre-coat on a colorimetrically different media which does not comply with definitions and formulae of CIE's whiteness and tint.

Abstract translation: 提供了包括算法和使用这种算法的计算设备的技术来计算来自CMYK的白色油墨分离通道或来自作为输入的打印流水线的RGB数据。 该输入最初对应于具有标准白度的介质上的打印数据，例如。 标准白度对应于由国际化妆品协会（CIE）1964介质白度公式使用的扩散器。 在示例实现中，由计算设备使用这种算法计算的白色墨水通道可以作为预涂层印在不符合CIE白度和色调的定义和公式的比色不同的介质上。

Abstract: An inkjet printer is placed in communications with a print production planning and scheduling system to allow planning, monitoring, and adjusting of an automatic digital (ink jet) printing production line. In one embodiment, the order of the print jobs is defined by the print shop owner or by the associated supervisor. Each job becomes a paper based (printed) job ticket and the order in which the jobs arrive at the print operator side defines the print order. The same is true for the order at the RIP side. Any change in regards to this order requires a direct communication of the print shop owner or supervisor with the printer or RIP operator.
