Cleaning fluid and cleaning method
A cleaning fluid for cleaning a site to which ink adheres in an inkjet printer which ejects aqueous inkjet ink containing a pigment and alkali-soluble resin having an acid group in a molecule, wherein the cleaning fluid contains an amphoteric surfactant, a basic compound, and water, a pH range of the cleaning fluid is from 9 to 12, the amphoteric surfactant is at least one selected from a group consisting of dimethyl lauryl amine oxide, lauryl dimethyl amino acetic acid betaine and a 2-al-kyl-n-carboxymethyl-n-hydroxyethyl imidazolinium betaine and is contained in an amount of 0.1 to 3% by mass to the total amount of the cleaning fluid.
ANILOX ROLL CLEANING BLANKET AND ASSEMBLY
A micro-fibre anilox cleaning blanket having a cleaning surface area defined by a first pair of parallel edges located on opposing ends of the blanket and a second pair of edges that run between said end edges along either side of the blanket is provided. A connection strip is provided on each end edge of the blanket. The connection strips are configured to form non-permanent slotted relationships with complementary connection elements on print cylinder attachment means such that the blanket can be mounted on a print cylinder. Also provided is a system that includes a plurality of cleaning blankets and a variety of different types of print cylinder attachment means that can be combined to achieve a wide range of cleaning blanket assemblies that correspond to different print cylinder designs.
CLEANING LIQUID FOR LIQUID EJECTING APPARATUS, LIQUID EJECTING APPARATUS, AND CLEANING METHOD FOR LIQUID CHANNEL
A cleaning liquid for a liquid ejecting apparatus to be fed into liquid channels of a liquid ejecting apparatus contains at least a water-soluble organic solvent, a silicone surfactant, and an acetylenic diol surfactant. At least part of the inner surfaces of the liquid channels is made from a fluorine-based material.
Micro-Fiber Anilox Roll Cleaning Plate
A micro-fiber cleaning plate comprising: a micro-fiber sheet including fibers that extend outward from a surface of the microfiber sheet in a uniform direction; a leading edge locking strip connected to the micro-fiber sheet along a first edge; and a rear edge locking strip connected to the micro-fiber sheet along a second edge opposite the first edge, wherein the leading edge locking strip engages to the rear edge locking strip to secure the micro-fiber cleaning plate to a roll of an anilox print system.
Cleaning Fabric and Related Apparatus and Methods
A printing system cleaning fabric (13), having a first layer (131) with a first cleaning surface (131), and a second layer (132) with a second cleaning surface (1321) facing away therefrom. The first and second layers (131, 132) extend parallel to each other and have a respective inner surface (131, 132) attached to the other along an extension of the cleaning fabric (13). The first and second layers (131, 132) have different permeability characteristics.
Micro-fiber anilox roll cleaning plate
A micro-fiber cleaning plate comprising: a micro-fiber sheet including fibers that extend outward from a surface of the microfiber sheet in a uniform direction; a leading edge locking strip connected to the micro-fiber sheet along a first edge; and a rear edge locking strip connected to the micro-fiber sheet along a second edge opposite the first edge, wherein the leading edge locking strip engages to the rear edge locking strip to secure the micro-fiber cleaning plate to a roll of an anilox print system.
CLEANING SYSTEM ARCHITECTURE WITH RECIRCULATING BATH FOR VARIABLE DATA LITHOGRAPHIC PRINTING
A variable lithographic cleaning apparatus, system and method works on the principle that dust and ink residue may be transferred from a lower surface energy reimageable conformable blanket surface to a higher surface energy surface low durometer cleaning member, such as the tacky roller, and then to an even higher surface energy cleaning member, such as the hard roller, which is hard and robust to scratching. The hard roller can then been scrubbed clean by an ink flushing device having a third cleaning member, such as a melamine sponge, wetted with a cleaning solution with the hard roller dried upon each rotation.
Roll of cleaning fabric and related apparatus and methods
A roll of cleaning fabric is used for cleaning printing cylinders of a printing system. The cleaning fabric (13) is impregnated with a cleaning composition containing an organic solvent and a cellulose solubilizer. The roll may be wound around a core (14) and inserted in a removable sealing bag (15) configured to seal around the roll (12) of cleaning fabric (13) in order to prevent the cleaning composition from evaporating before use.
Roll of Cleaning Fabric, and Methods Thereof
In a method for cleaning cylinders included in a printing system, a roll of cleaning fabric is used. The roll (12) has a bobbin (14) coated with a water repellent, and the cleaning fabric (13) is wound onto the bobbin (14). The cleaning fabric (13) is impregnated with a cleaning composition containing water in a concentration of between 5 and 50 wt %.
TUNABLE SURFACTANTS IN DAMPENING FLUIDS FOR DIGITAL OFFSET INK PRINTING APPLICATIONS
A dampening fluid useful in offset ink printing applications contains water and a surfactant whose structure can be altered. The alteration in structure aids in reducing accumulation of the surfactant on the surface of an imaging member. The surfactant can be decomposed, switched between cis-trans states, or polymerizable with ink that is subsequently placed on the surface.
