KBA Rapida: 11 Jobs Under 90 Minutes
WURZBURG, Germany—Within the framework of a print test for a German Internet printer, a five-color version of a Rapida 75 press with coater and extended delivery took just 55 minutes to print seven 300-sheet jobs at the KBA Customer Center in Radebeul in March. In the next 30 minutes, the press completed four additional postcard and business card forms. After 90 minutes, the press had completed 11 different production jobs.
The Rapida 75 achieved the above output with semi-automatic plate changing. A pile change at the feeder and delivery was necessary for the seven jobs printed on 350 gsm matt art paper. A first pull was taken after 30 sheets in each case to measure and adjust the ink densities with KBA DensiTronic. After 100 sheets, the densities were measured again (without adjustment). The first saleable sheets were in the delivery without stopping the press after around 100 sheets. The measured values remained stable within the tolerances defined by ISO 12647-2 (Process Standard Offset) over the whole run, and the Rapida 75 was printing at 15,000 sph both for makeready and for the actual production.
The Rapida 75 is equipped with practice-oriented features geared to fast job changeovers and ease of operation, alongside the smallest footprint in its format class and an energy consumption up to 50 percent below that of comparable presses. The latter points are of particular interest to companies with limited space and a commitment to climate-friendly production.
