Abstract: A flexographic preview printer for duplicating conditions of a contemplated press run. The preview printer includes an inking unit and a printing unit. The inking unit has an ink roller and an anilox roller with a doctor blade for precision metering of the ink on the anilox roller. The printing unit includes a plate roller and a drive roller. The nip between the plate roller and the drive roller is adjustable. There are first and second motors and first and second gear trains. The first motor and gear train drives the inking unit at a set slow speed through a throw-out clutch. The second motor and gear train drives the printing unit at a speed that is higher than the speed at which the first motor rotates the inking unit. The second gear train is meshed with the first gear train through a throw-in clutch. The second gear train drives the first gear train through the throw-in clutch when the second motor is activated while the first gear train is disengaged from the first motor by the throw-out clutch.

Abstract translation: 用于复制预期压机运行条件的柔性版预览打印机。 预览打印机包括着墨单元和打印单元。 上墨单元具有墨辊和具有刮刀的网纹辊，用于在网纹辊上精确计量墨水。 印刷单元包括印版辊和驱动辊。 平板辊和驱动辊之间的辊隙可调。 有第一和第二马达和第一和第二齿轮系。 第一台电机和齿轮系通过一个抛出离合器以一定速度驱动着墨单元。 第二马达和齿轮系以比第一马达旋转着墨单元的速度高的速度驱动打印单元。 第二齿轮系通过坠落离合器与第一齿轮系啮合。 当第二齿轮系通过抛出离合器与第一马达脱离啮合时，第二齿轮系通过引入离合器驱动第一齿轮系。
