Transalkylation catalysts comprising acidic molecular sieve, palladium and germanium have good activities and attenuate aromatic ring saturation and lights co-production provided that sufficient palladium is contained in the catalyst. The variable delay means, by imparting a delay of a number of delay cycles that differs for each input cycle and moreover for each port to each unit of data of a data group that is applied as input to a plurality of ports and in a plurality of cycles, switches the order of the data in the same port and supplies the data as the data group at a predetermined delay. Next, an aqueous ultraviolet primer layer is applied over the substrate and the indicia.
