The job of designing and printing the new stamp was carried out in a great rush; engraving began only on May 4, and stamp printing on May 10 (a Friday), in sheets of 100 (contrary to the usual practice of printing 400 at a time and cutting into 100-stamp panes). Since the stamp was printed in two colors, each sheet had to be placed into the flat-bed printing press twice, an error-prone process that had resulted in invert errors in stamps of 1869 and 1901, and at least three misprinted sheets were found during the production process and destroyed. It is believed that only one misprinted sheet of 100 stamps got through unnoticed.
