Swiss Cross and Numeral issues: varieties
A large number of postage stamps were used in the 1870s. Between 1877 and 1878, sales figures increased by 30%. This is due to the fact that using postage stamps for parcels has been made compulsory.
Since the combined typography-relief printing process was still being used, the stamps were expensive and the production time long. It was therefore decided to prepare printing of new values that would be printed only in typography.
|Two types of control marks:
Type I: 1882-1889,
Type II: 1893 onward.
The new set was designed by professor Hassert from Stuttgart and printed in Bern by Stämpfli & Co. The difficulties in the delivery of granite paper forced the printing company to use the white paper available from the previous issues. Subsequently, from 1882 to 1889, stamps were printed on granite paper with the Type I control mark.
In 1887 the Health Department of Bern informed that the yellow color of the 15 centime stamp was dangerous because it contained iron oxide and chromic acid. As no other mixture for yellow color was available another color was chosen for 15 cents stamp.
In 1889, the heraldically correct form of the Swiss cross was established by the Federal Decree. As a result, in 1893, the new plates of the control mark Type II were produced.
After further technical improvements of the Printing House of Berne, from 1906 onward, the stamps were printed again on granite paper, this time with the “Swiss Cross” watermark.
