摘要:
According to the present invention there is provided a method for making a lithographic printing plate comprising the steps of applying a first magnetic field to a dry, light absorbing powder, which comprises a magnetic material and a hydrophobic thermoplastic binder, thereby coating said powder on a surface of a metal support; image-wise exposing to light the powder in contact with the surface of the metal support, thereby increasing the adhesion of the powder to the surface of the metal support, without substantially ablating the powder; and removing the non-exposed magnetic powder from the surface of the metal support under action of a second magnetic field with a polarity substantially opposite to the first magnetic field.
摘要:
A method of inkjet printing includes using a grayscale inkjet print head. The inkjet print head is driven driving to eject a number of successive ink droplets from the ink chamber in accordance with print tone data provided to the grayscale print head, the number of successive ink droplets forming a multiple-droplet drop creating a printed dot of appropriate tone on the receiving medium. The method includes the step of excluding print tone data corresponding with the ejection of a single-droplet drop from being provided to the grayscale print head. A preferred embodiment includes the removal of this print tone data from the data provided to the grayscale print head. A more preferred embodiment includes applying a multilevel halftoning technique for avoiding the use of print tone data corresponding with a single-droplet drop during the generation of the print tone data for inkjet printing the image with the grayscale print head.
