Abstract: Sublimation dyeing uses first and second donors, with heat being applied simultaneously from both sides of the object. Receivers can be woven, non-woven, knitted or not knitted, or any combination of these, or any other factors, and are contemplated to include fabrics used for clothing, banners, flags, carpets, wall hangings, and so on. Process parameters use lower temperature and longer dwell times than for one-sided sublimation printing, most preferably dwell times of between 70 seconds and 120 seconds, and a sublimation temperature of less than 400° F. (204.4° C.). Solids and patterns can be reproducibly printed, even in small lots, and can facilitate just in time production of clothing and other materials.

Abstract: A color printing method for a franking system making it possible to print a franking mark on a mailpiece using at least three primary inks, namely cyan, magenta, and yellow, wherein at least one of said primary inks, namely cyan or magenta, is constituted by a similar postal ink, namely postal blue for cyan and/or postal red for magenta.

Abstract: In an off-set printing device suited to multi-colored printing the printing plate support and the printing carrier support are arranged on a common carrier plate between two parallel racks connected with the carrier plate and extending in the printing direction. The printing roller is freely removable from the carrier plate and has at each of its axial ends a spur gear or pinion for engagement with an associated one of the racks, and the roll of the printing roller is freely rotatable relative to a shaft provided with hand grips. On the carrier plate--in the printing direction--in front of the printing plate support and on the printing roller at least one projection and a complementary recess are provided which in the presenting of the printing roller to the carrier plate engage with one another.

Abstract: An apparatus in which successive layers of charged particles are transferred, in superimposed registration with one another, to a sheet of support material. The sheet of support material is reciprocated so that successive forward movements thereof are in synchronism with the movement of the charged particles. On the return movement, the sheet of support material is located in a position to initiate the transfer of the next successive layer of particles in superimposed registration with the previously transferred layer of charge particles during the forward movement thereof.
