METHOD OF INITIATING ACTION IN COMPUTER SYSTEM VIA ANALOG-PRINTED SUBSTRATE
First Claim
1. A method of initiating a requested action in a computer system via a printed substrate, the substrate containing human-readable information and machine-readable coded data, the method including the steps of:
- positioning a sensing device in an operative position relative to the substrate;
sensing at least some of the coded data;
generating indicating data in the sensing device using at least some of the sensed coded data, said indicating data enabling the computer to identify the requested action; and
sending the indicating data to the computer system,wherein said coded data comprises a phthalocyanine salt comprising one or more sulfonate groups, wherein a counterion of at least one sulfonate group is an ammonium cation comprising at least 20 carbon atoms.

Abstract
A method of initiating a requested action in a computer system via a printed substrate. The substrate contains human-readable information and machine-readable coded data. The method includes the steps of: positioning a sensing device in an operative position relative to the substrate; sensing the coded data; generating indicating data in the sensing device using the sensed coded data; and sending the indicating data to the computer system. The coded data comprises a phthalocyanine salt comprising one or more sulfonate groups. A counterion of at least one sulfonate group is an ammonium cation comprising at least 20 carbon atoms.
