| 20120044292 | Vacuum Control For Print Head of A Printing System - According to an aspect of the disclosed subject matter, a controller to maintain negative pressure in a print head of a printing system includes: control loop feedback logic to receive a set point and an output of a vacuum sensor associated with the print head; a regulator coupled with an output of the feedback logic; and a driver coupled with the regulator and configured to output a drive signal to a pump, which is associated with the print head, responsive to an output of the regulator. According to another aspect of the disclosed subject matter, a vacuum control assembly for a printing system includes: a body having one or more associated accumulators; a pump coupled with the body; and one or more flexible tubes coupled with the one or more accumulators associated with the body and configured to restrict air flow within the vacuum control assembly. | 02-23-2012 |
| 20110267416 | Laser Marking Using Scalable Fonts - A system directs a laser beam to mark a material with an alphanumeric code. Character and quality information corresponding to a mark to apply to the material with the laser beam can be received, a font definition that specifies character segments can be obtained, a set of multiple spaced locations can be generated from the character segments in accordance with the character and quality information, and the material can be marked with the laser beam by directing the laser beam to dwell at the locations and move between the locations without deactivating the laser beam. | 11-03-2011 |
| 20110229239 | Printing Apparatus and Method of Printing - Systems and techniques relating to printing include an apparatus including a base mounting a storage spool to store printing ribbon including a web carrying marking medium, the base mounting a ribbon take-up spool. A ribbon path from the storage to the take-up spool runs through a printing station where there is a print head, and printing is effected at the printing station when relatively moving the head and the substrate with the ribbon interposed between. The apparatus includes a movable ribbon guide member, a ribbon guide member drive device to move the ribbon guide member, and a controller which, during or in between at least some printing operations, controls drive of at least the take-up spool to advance ribbon through the printing station. The controller controls the ribbon guide member in response to an input signal representative of ribbon tension along the ribbon path to adjust the ribbon tension. | 09-22-2011 |
| 20110012954 | SOLVENT-BASED INKJET INK FORMULATIONS - Solvent-based inkjet ink formulations including an organic solvent, a resin, a surfactant, and a colorant are provided. The inks have many desirable attributes such as extended decap time. | 01-20-2011 |
