Centenary of the Malta Post Office issue and other issues

Abstract

Issue X - This set was produced in multicolour using four different colours for each value. Issue Y - This set was produced in multicolour using five different colours for the 2c and 27c values, and four for the 13c value. Issue Z - All values of this set were printed using the same four colours: Sepia, Red, Gold and Light Yellow. Colour checks in the form of coloured discs 3 mm in diameter are seen in the right hand margin, next to the last stamp of the bottom row, in each Pane, of each value, of issues X, Y and Z. Colours from top to bottom correspond to the colours used for Pane numbers from left to right, on all Panes, of all values, in issues X and Z, but from right to left in issue Y. Cumulative totals of progressive columns of stamps, are seen in top and bottom margins, printed in black in all Panes, of issues X and Y, but printed in the top colour of the colour checks, in issue Z.
