Abstract: The system is the combination of an envelope feeder and a laser printer, with some additional control mechanisms. An envelope conveyor system is positioned adjacent to a media input slot on a laser printer and envelopes are fed into a pickup assembly positioned within the media input slot in a controlled manner. By controlling the conveyor speed, a stack of envelopes having a limited and known number of envelopes is accumulated within the pickup assembly such that the pickup roller in the assembly can feed envelopes into the printer at a rate equal to or greater than the speed at which the printer can apply an image to each envelope. A control circuit provides a feedback signal to the conveyor to control conveyor motor actuation. The result is a smaller, less expensive and simpler feed system for an envelope printer.

Abstract: An envelope feeder for a printer having two aligned conveyors moving at different speeds is disclosed. An upstream conveyor moves a backwards slanted procession of envelopes having aligned upper edges onto an inline downstream conveyor that accelerates the envelopes along a curved upper edge so that by the time any single envelope arrives at the printer ingestion or feed slot, the envelope is almost completely flat yet supported upwards slightly so that the pickup roller of the printer can easily and reliably ingest the envelope for processing. Due to the speed of the downstream conveyor, envelopes are continually and reliably presented to the printer to avoid printer stalls. The configuration reduces the amount of skill and operating labor required to establish a high-speed envelope feed source for high-speed printing.

Abstract: A system and method for matching spot colors in a PDL document with actual printed output is disclosed. A pre-press workflow application identifies spot colors in a PDL document and creates a table of potential substitute color tiles, each having color characteristics similar to the original spot color. These tiles are then printed in a “swatch page” of numerically assigned colors and reviewed by the user for potential selection over the original spot color values. A substitute color may then be selected from the swatch page and the pre-assigned numerical value for the selected color tile input into the workflow application. The PDL document is then altered to record the color change. The resulting printed document more closely matches the desired spot color and the process can be repeated for any print environment to allow for more consistent printing results and lower print job costs.
