A cost-effective multi-channel capillary gel-electrophoresis system for highly efficient, high speed, high throughput, carbohydrate analysis. The automatic accompaniment apparatus can generate derivative accompaniment style data from original accompaniment data with ease. When moving to a different set of printing conditions, a single test print is then carried out and a new dot gain estimation is available. The logical gate chain includes a plurality of first logical gates associated with the columns and connected in series. The method further includes using a processor device operably coupled with the memory device for executing the computer-executable instructions from memory.
