Abstract: The present embodiments relate to a printing apparatus capable of mitigating/preventing instances of turbulent deviation of ink jetted from print heads when printing onto a substrate, a severe form of which looks like woodgrain. The printing apparatus can include a jet plate that has a first width and that is disposed between the substrate and a series of print heads. The jet plate can also include a series of apertures formed in the jet plate that each correspond to one or more of the print heads, as well as a cutout portion at a first end of the jet plate that has a second width less than the first width.

Abstract: Disclosed here is a system enabling users/customers to receive an objective assessment of the performance of a printer. This is accomplished by comparing a quality score of an earlier-in-time image with a quality score of a later-in-time image. A processor analyzes each image based on several criteria and uses various image-analysis methods, to flag errors within an image. A numeric quality score, based on the number of errors, is provided to the user to objectively evaluate whether the printer has degraded or not. Thus, the user can objectively present an argument to a salesperson or manufacturer that the user is due a remedy.

Abstract: A printing system includes a driving belt configured to drive media through the printing system relative to one or more print heads and a vacuum conveyor system. The vacuum conveyor system includes a vacuum chamber cover having a first surface and a second surface opposite the first surface, as well as a plurality of slots through the cover that form openings from the first surface to the second surface. A seal, disposed within and extending along at least a portion of a length of a respective slot, is drivable to open or close the respective slot. A vacuum chamber below the second surface of the vacuum chamber cover is configured to apply a vacuum to the media through the plurality of slots. The applied vacuum constrains the media on the driving belt by flattening it against the driving belt.

Abstract: A shape packing technique is introduced that can be applied in various applications such as automated print production. In an example embodiment, items that are to be placed into a target shape are sorted based on size to form item groups that include similarly sized items. Potential blocks including arrangements of one or more items are created from the sorted item groups. A placement solution is then generated by placing the potential blocks in the target shape using a recursive process that avoids redundant placement solutions until all of the potential blocks are placed or no other potential blocks are able to be placed. The placement solution can then be utilized, for example, to control a printer to print multiple images on a substrate and/or to control an automated cutting device to cut the substrate into multiple partitions according to the placement solution.

Abstract: The disclosed embodiments relate to a wide format single pass printing apparatus. The printing apparatus can include multiple print housings configured to receive print beams with print heads configured to print onto a substrate. The print housings can be horizontally adjacent to one another relative to a horizontal plane. The print housings can also be oriented opposite to one another. The print beams can be inserted and/or removed from each print housing from opposing ends, allowing for greater ease of access to the print beams.

Abstract: A printing system having a vacuum transfer belt conveyor includes a fixed or movable perforated platen that supports workpieces, e.g., substrates, boards or other parts, to be printed. The printing system is configured to apply vacuum action through apertures or perforations defined through the perforated platen. In an embodiment, the print system is configured to mitigate deflection of ink drops, through the implementation of both a passive system, which reduces air flow in the region below the a print bar that includes one or more printheads, as well as an active system, which distributes the workpieces, e.g., substrates or boards, with respect to perforations in the transfer belt. In some embodiments, the perforated platen is comprised of a plurality of modular plates.

Abstract: Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.
