An effective short-term remedy for many of the printing defects that the digital ladder target diagnoses is to reduce the ink density in the affected area.Experienced press personnel will instinctively lower the ink feed to even the tonal appearance of the printing.However,this solution is not ideal because the midtone range is saved at the expense of the shadows and saturated colors.A better approach is to identify and cure the source of the excess directional gain so that density aimpoints can be achieved without sacrificing midtones.The digital ladder targets on the Digital Sheetfed Test Form 4.2 have solid ink targets before and after each target to monitor inking level in-line with the printed target.The density aimpoints should be met to prevent misleading evaluation of the printed target.
In studies of process variability,there are many samples taken during the run according to the sampling plan appropriate for the experimental purposes.To analyze process variability with digital ladder targets,the sample sheets are stacked in order and fanned out so that consecutive targets from one side of the sheet can be seen together.When sufficient samples are available,this viewing is facilitated by cutting the samples perpendicular to the digital ladder targets.The cut targets are then fanned out as shown in Figure 2-7b.
If the pattern of digital ladder targets produced by the fanned-out display shows noticeable variation,periodic image transfer problems are occurring.Other periodic disturbances such as gear streaking,cylinder bounce,or inker variation,are more easily seen when multiple samples are evaluated together.
The digital ladder target is a very sensitive device.If a sample is found in conformance for density,if all digital ladder targets are imaged such that none of the individual sections on any target are visibly distinct from the others,and if all digital ladder targets are uniform in density from gripper to trailing edge,there is good assurance that many serious print problems are absent from the printing system.This is a very good indication of overall reproduction quality

一个有效的短期治疗许多印刷缺陷中数字梯子目标的诊断是为了降低墨水密度患处.有经验的新闻人员将会本能地降低墨水饲料,即使色调外观的印刷.然而,这个方案不理想,因为midtone范围是救了为代价的阴影和饱和的颜色.一个更好的方法是去识别和治疗源多余的定向中获得如此,可以达到aimpoints密度不牺牲midtones.数字梯子上的目标数字Sheetfed考试表格4.2有扎实的墨水目标之前和之后的每一个目标,监控油墨水平管道和印出来的目标.aimpoints密度应该会防止误导评价的印刷的目标.
在研究过程中,有许多变化在路跑时采样根据抽样计划适合实验的目的.分析过程变化与数码梯子目标,样品表被堆放在秩序和分散开,从一个侧面连续目标可以看到板材在一起.当足够的样品是可得到的,这观看由各行业切割成实样垂直于数字梯子目标.伤口然后东西分散目标如图2-7b.
如果模式产生的目标数字梯种成扇状分叉的显示器显示明显的变化,周期影像传输问题发生.其他周期性干扰,如齿轮条纹,缸反弹,或着墨变化,更容易看到,当大量样品进行了评估在一起.
数字梯子的目标是一个非常敏感的装置.如果一个样本中发现,如果他们都为密度符合数字梯,成像目标没有单独的部分,任何目标明显不同于其他人,如果所有的数字梯密度均匀的目标是在吸力面从微夹钳,有很好的保证许多严重的打印问题缺席印刷系统.这是一个非常好迹象整体复制质量
