AB - This paper discusses an analytical investigation of the motion quality requirement of an image carrier withrespect to the given allowable image misregistration between the primary colors. The system analyzed isconcerned with a one pass configuration in which the image carrier traverses by sequentially multipleimaging stations in a single pass. Examples of such a system are full width ink jet color printers and thermaltransfer color printers.The motion quality of the image carrier, which is the printed substrate in the above examples, impactsdirectly the positional registration between the colors and in turn the print quality. To characterize theimage carrier motion, its traversing velocity is represented by the Fourier sum of the dc and ac components.The amplitude and frequency of the ac velocity component are used as the characteristic measure in thecontext of motion quality.The analytical expression for motion quality is derived by applying one ac velocity component at a time. Thefrequency domain spectrum is then generated by sweeping the frequency through the range of interest. Anintriguing phenomenon called "error synchroneity" can be shown when the spatial period of the ac velocitycomponent is an integer fraction of the distance between the imagers. At these frequencies, the positionalerrors of the different color images are offset, regardless of their amplitude. Consequently, the print of thecomposite images is perceived to be in registration, without color shifts and other associated problems.
