A decorator press for printing on metal cans has a pump unit, a distribution head, a sensing device and a processing circuit. The pump unit comprises a plurality of inlet ports, a first inlet port configured to receive an ink of a first color from a first ink source and a second inlet port configured to receive an ink of a second color darker than the first color. The distribution head is coupledto the pump unit and configured to spread fluid received from the pump unit across zones of a print roller. The sensing device is coupled to the press and configured to sense a characteristic of fluidflowing out of the distribution head. The processing circuit is configured to receive the sensed characteristic, compare the sensed characteristic to a predetermined threshold, and to provide an indication to a display based on the comparison. 种用于在金属罐上印刷的装饰印刷机具有泵单元、分配头、感测设备和处理电路。泵单元包括多个入口端口，被配置成从第油墨源接收第颜色的油墨的第入口端口和被配置为接收比第颜色深的第二颜色的油墨的第二入口端口。分配头联接到泵单元，并且被配置成将从泵单元接收的流体散布到印刷辊的区域上。感测设备联接到印刷机并且被配置成感测流出分配头的流体的特性。处理电路被配置成接收感测到的特
