Laser printing method and device for implementing said method

A method for printing uses at least one ink. The method includes: a step of focusing a laser beam so as to generate a cavity in an ink film; a step of forming at least one ink droplet from a free surface of the ink film; and a step of depositing the droplet onto a depositing surface of a receiving substrate positioned at a given distance from the film. The laser beam is oriented in the direction opposite the gravitational force. The free surface of the film is oriented upwards towards the depositing surface placed above the ink film.

CONTAMINANT CONTROL PROCESS IN A RETRANSFER CARD PRINTER
20180141327 · 2018-05-24 ·

A retransfer printing process that prevents dust and other contaminants from becoming statically or otherwise attached to the transfer layer of the retransfer film and/or to the print ribbon used to print on the retransfer film. In the described process, some or all of the unused retransfer film is rewound back onto the retransfer film supply and/or some or all of the unused print ribbon is rewound onto the print ribbon supply, for example until the next print job is submitted.

METHOD FOR PROTECTING PRINTED DATA
20180134050 · 2018-05-17 · ·

Method for protecting printed data on a varnish area of a transfer film of a heat-transfer machine, including: a varnishing step during which the varnish area and a plastic card advance simultaneously under the thermal head and during which the thermal head heats in order to deposit the varnish on the plastic card, generating a deformation of the transfer film at a text printed on the plastic card; a rewinding step during which the transfer film is rewound in order to position the varnish area upstream of the thermal head, and the plastic card is repositioned upstream of the thermal head; and a defacing step during which the varnish area and the plastic card advance simultaneously under the thermal head and during which the thermal head heats at the level of the text and at the deformation in accordance with a sign scheme making the deformation illegible.

VARIABLE TENSION AND/OR TRANSPORT SPEED RETRANSFER PRINTING PROCESS

Retransfer printing methods and systems are described where a variable stripping process is utilized while stripping all or a portion of the retransfer film (also known as intermediate transfer media) from the surface of a substrate. The variable stripping process includes stripping the retransfer film from different sections of the substrate surface while applying different tensions to the retransfer film and/or at different transport speeds of the retransfer film and the substrate.

Method and apparatus for transferring a printing substance onto a substrate by means of laser radiation

A method for transferring a printing substance provided as a coating on a carrier onto a substrate by laser radiation from a laser beam source that comprises an amplifier and that has an output power includes initiating a transfer process at the start of an active phase during a first time period by a temporary increase in the output power above an upper power threshold of the laser radiation, and adjusting the output power during a second time period of the active phase following the first time period, wherein the output power is adjusted during the second time period constantly in the range between the upper power threshold and a lower power threshold. The laser radiation and the carrier are moved relative to one another and the output power of the laser beam source is time modulated.

AUTOMATED HEAT TRANSFER PRESS AND METHOD FOR AUTOMATED HEAT TRANSFER PRESSING
20170165389 · 2017-06-15 ·

An automated heat transfer press and method for automated heat transfer pressing provides an electric linear actuator motor that induces an arced translation of a first plate onto a second plate for dye sublimation printing. The arced motion of the first plate enables the first plate to press against the second plate at an angle, rather than a vertical pressing action; whereby adaption to a variously sized and dimensioned substrates is possible. A second link bar adjusts alignment of the second plate with first plate. An electric linear actuator motor manipulates a rod through electrical power. Rod is extended to create linear motion. The rod operatively connects to a hinged arm, applying linear force that causes the hinged arm to displace the first plate at arced motion. A control portion regulates the linear actuator motor to press and release the plates against each other in predetermined temperatures and intervals.
