Christmas 1996 - X, Treasures of Malta : Sedan chairs - Y

Abstract

These two sets were printed in the four colour process using the standard CMYK (Cyan, Magenta, Yellow, Black) process colours for each value. The progressive sheets in issues X and Y were printed in the following order: Black-Cyan-Magenta-Yellow. Colour checks in the form of coloured discs 3mm in diameter were printed in four different positions on the margins, of each Pane, of each value. They are seen next to the first and last stamps, of the top and bottom rows, in issues X and Y. The colours from top to bottom correspond to the colours used for Pane numbers, from left to right, in all positions. Cumulative totals of progressive columns of stamps are seen in the bottom margin only, in all Panes, of all values, printed in black, in issues X and Y. [excerpt]
