Abstract: A drying assembly is disclosed. An example apparatus includes fans; a temperature sensor; a print engine to access instructions to cause a printer to perform a printing operation on media; and a processor responsive to an output of the temperature sensor to control the fans to force air onto the media to cause a substantially uniform temperature to be maintained across a width of the media during the printing operation and to cause a sum of air flow output by the fans to be maintained at a substantially constant value.

Abstract: A measured distance is received from a distance sensor, where the measured distance is indicative of a distance between a color sensor and a substrate. Using the measured distance, a location of a given projection of projections of a substrate support is determined. A color of a color patch on the substrate at the determined location of the given projection is determined.

Abstract: A drying assembly is disclosed. The drying assembly has at least 2 fan units where each fan unit has a fan. The fan speed of each fan is adjusted independently to control the air temperature from the fan. The airflow through all of the fans is maintained at a constant value.

Abstract: Techniques related to printing are described herein. According to an example, color patches are to be printed on a substrate. The substrate can be positioned on a substrate support for operation of a color sensor in a color measurement zone. Dimension and location in the substrate of the color patches are selected such that, for each color patch, at least a portion of the color patch can be positioned on a support projection in the color measurement zone. In some examples, color analysis techniques are described.

Abstract: Disclosed herein is a method for a merchant to gain information about the purchasing characteristics of a group with which the merchant wishes to interact. Merchants wishing to target group members are not able to specifically identify members of the group through depersonalized transaction data available from financial institutions. Group members are therefore identified through a traditional method: market research. The method also includes noting the purchasing behavior of group members, including providers of goods and services to group members, merchants not patronized by members of the group, and demographic characteristics of the group. An example of such a group is the so-called “millennials”. The identification of group members may be validated through test runs of financial data and fine-tuned to ensure correct identification of group members.

Abstract: Methods for curing ink printed on a print medium are disclosed. The methods comprise heating air to a temperature suitable for curing the ink, and blowing the air through a plurality of holes onto the print medium.

Abstract: Examples are provided of controlling sheet media dryers. A controller operates a fan at plural duty cycles and correlates a resulting air pressure to each to define empirical data pairs. A parabolic curve fit to the empirical data is used to derive additional data pairs, and a lookup table is defined using the empirical and derived data pairs. The controller uses the lookup table to operate the fan during normal operations of a sheet media dryer.

Abstract: Systems and methods for wide format ink printing are described. In one embodiment, a tension module for wide format inkjet printers is described which includes a throughput roller comprising a material having a length to diameter ratio of at least 10:1 and a friction coefficient value less than 1. The tension module further includes a plurality of pinch rollers adjacent to and supporting the throughput roller, and a motor operable to rotate the throughput roller. The plurality of pinch rollers and the rotation of the throughput roller in combination are operable to draw the print medium between the plurality of pinch rollers and the throughput roller.

Abstract: Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium.

Abstract: Ink drying methods and apparatus are disclosed. One example ink drying apparatus includes a resistive heating element having a first power dissipation density adjacent to a center region of a print media travel path and a second power dissipation density adjacent to an edge region of the print media travel path, wherein the first and second power densities are not equal.

Abstract: This invention refers to a process for purifying sugar syrup, usually called liquid sugar, prepared with raw granulated cane sugar, in order to obtain a product called purified liquid sugar, with a degree of purity, referred to the content of ashes and color, similar or greater that the purity of a syrup prepared from refined granulated cane sugar, which is equivalent to a content of ICUMSA conductimetric ashes below 0.04% and a color of less than 45 ICUMSA units. The increase in direct reducing sugars content in the product is less than 0.2% with respect to the content of reducing sugars present in raw granulated cane sugar used as raw material for this process, and the pH is kept in the range of 6.0 to 7.5.
