The original state issues were printed by Bradbury Wilkinson & Sons in the United Kingdom, in sheets of 200 in two panes of 100, 10 x 10, for the values of 1c, 2c, 5c, 6c, 10c, 15c and 20c. The printing process was lithography. Colour separation proofs for each individual colour were printed for each value, and the colours combined in a process that eventually produced a full colour proof. These proofs were produced, initially, in small units, four or so and later as full sheets. This printing took place to ensure that all colours printed correctly when combined and also registered correctly. The more common sheet proofs can be easily identified from the smaller units as the latter have white borders. The stamps printed as sheets had a design that allowed for 'bleeding' between each stamp, printing over the perforations. Each value had two separate black colours, the first was applied as detail for the butterfly and the stamp value, being common for all States. and the second for the State name, Rulers portrait and/or State coat of arms, this being the 'customising' colour for the base stamps. In addition to sheet stamps, two values, 10 cents and 15 cents, were produced as coil stamps for use in vending machines in several locations throughout Malaysia. The designs were similar to the state values, but produced with 'Malaysia' in place of a state name as they were for use in any state. These coils were printed by Harrison & Sons in photogravure. From the start, the coil stamp machines proved to be inefficient at dispensing the correct values for the money tendered, possibly due to humidity affecting the stamps. Due to these problems, the machines were dispensed with quite soon after they commenced their duty. As a result, commercially used examples of both values are scarce. During 2006 a variant of the gum was identified. It is brown, with a clear 'ribbing' effect. This may have been a trial to overcome some of the problems with the machines, the ribbing possibly helping to prevent curling of the individual stamps. Harrison Proof Cards exist for both values with an imperforate stamp in full colour on each. During 1978, unannounced reprints for some state values were issued printed in photogravure by Harrison & Sons, the same printer that produced the coil stamps earlier. Some of these reprints are quite scarce, particularly the Perlis 10 cents and Sabah 20 cents values, as they were replaced by the new issue of Flowers and Animals the same year, and the new issue had not been announced by the post office.
