  • Publication number: 20070211124
    Abstract: An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.

  • Publication number: 20070120917
    Abstract: Disclosed is a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730 and a polydispersity of from about 1.05 to about 3.0. Also disclosed is a process which comprises (1) incorporating into an ink jet printing apparatus a phase change ink comprising (a) a colorant and (b) a phase change ink carrier, said carrier comprising (i) a branched triamide and (ii) a polyethylene wax having an average peak molecular weight of from about 350 to about 730 and a polydispersity of from about 1.05 to about 3.0; (2) melting the ink; and (3) causing droplets of the melted ink to be ejected in an imagewise pattern onto a substrate.

  • Publication number: 20070120924
    Abstract: A radiation curable phase change ink preferably used in piezoelectric ink jet devices includes an ink vehicle that includes at least one gellant comprised of a curable polyamide-epoxy acrylate component and a polyamide component, and at least one colorant. The use of the gellant enables the ink to form a gel state having a viscosity of at least 103 mPa·s at very low temperatures of about 25° C. to about 100° C. The ink may thus be jetted at very low jetting temperatures of, for example, about 40° C. to about 110° C. The ink may be used to form an image by heating the ink to a first temperature at which the ink may be jetted, jetting onto a member or substrate maintained at a second temperature at which the ink forms a gel state, and exposing the ink to radiation energy to polymerize curable components of the ink.

  • Publication number: 20070120908
    Abstract: The phase change ink a viscosity of from about 4 mPa-s to about 50 mPa-s at a first temperature and has a viscosity of from 104 mPa-s to about 109 mPa-s at a second lower temperature. The second temperature may be below the first temperature by at least 10° C. but by no more than 50° C. The first temperature may be from about 60° C. to about 110° C. and the second temperature may be from about 20° C. to about 70 ° C. A curve of log10 viscosity of the phase change ink plotted against temperature in degrees Celsius may have a slope having an absolute value less than 0.02 at the first temperature and have a slope having an absolute value greater than 0.08 for at least a region second temperatures.

  • Publication number: 20070120925
    Abstract: Curable monomer that is liquid at 25° C., curable wax and colorant together from a radiation curable ink. This ink may be used to form images by providing the radiation curable ink at a first temperature; applying the radiation curable ink to the substrate to form an image, the substrate being at a second temperature, which is below the first temperature; and exposing the radiation curable ink to radiation to cure the ink.

  • Publication number: 20060167464
    Abstract: Systems, methods, and apparatuses for tensioning an orthopedic surgical cable used in conjunction with an orthopedic implant device, a bone, and/or bone implant or structure. At least one device in accordance with various embodiments of the invention includes a handheld body handheld body capable of receiving a portion of the orthopedic surgical cable. The handheld body includes a clamping body adapted to restrain a first portion of the orthopedic surgical cable with an adjustable gripping force, wherein a tension is placed on the orthopedic surgical cable. The handheld body also includes an adjusting mechanism adapted to cooperate with the clamping body to change the gripping force on the orthopedic surgical cable. In addition, the handheld body includes a slide adapted to change the position of the clamping body relative to the handheld body.
