Abstract: A color measurement system laterally determines chromatic characteristics of a printed substrate. A measurement carriage includes a measurement head for laterally moving across the printed substrate and a measurement magnetic coupler slidably mounts onto a measurement rail positioned on a first side of the printed substrate. A backing carriage includes backing surface(s) and backing magnetic coupler(s). Each backing magnetic coupler is associated with a respective backing surface. Each backing magnetic coupler can be coupled with the measurement magnetic coupler for coupling the measurement carriage with the backing carriage. The backing carriage slidably mounts onto a backing rail positioned on a second opposite side of the printed substrate. The measurement carriage or backing carriage includes a motor for moving across a respective measurement rail or backing rail. Another measurement carriage and backing carriage move across another measurement rail and backing rail by coupling with the first measurement carriage and backing carriage.

Abstract translation: 颜色测量系统横向确定印刷基板的色彩特性。 测量托架包括用于横向移动穿过印刷基板的测量头和可滑动地安装在位于印刷基板的第一侧上的测量导轨上的测量磁耦合器。 背衬托架包括背衬表面和背衬磁性耦合器。 每个背衬磁性耦合器与相应的背衬表面相关联。 每个背衬磁耦合器可与测量磁耦合器耦合，以将测量托架与背衬托架耦合。 背衬托架可滑动地安装在位于印刷基板的第二相对侧上的背板上。 测量滑架或背板滑架包括用于在相应的测量轨道或背衬轨道上移动的马达。 通过与第一测量托架和背衬托架联接，另一个测量滑架和背板支架通过另一个测量导轨和背衬轨道移动。
