20210379905 · 2021-12-09 ·

A drawing system according to an embodiment of the present disclosure includes a storage, an operation section, and a drawing section. The storage stores a characteristic function that derives output setting values of light sources on the basis of drawing coordinates, an absorbance correlation value, and gradation values in a leuco color space. The operation section derives the output setting values by inputting, to the characteristic function, the drawing coordinates, gradation values of leuco image data described in the leuco color space, and an absorbance correlation value obtained by measuring the recording medium. The drawing section includes the light sources, and controls output of the light sources on the basis of the output setting values derived by the operation section to thereby perform drawing on the recording medium.

The web has an air permeability of 0-3500 L/m.sup.2/s, and comprises an upper surface fiber layer, at least one middle ink-receiving layer, and a lower surface fiber layer sequentially connected. Fibers in the upper surface fiber layer and lower surface fiber layer have a fiber fineness larger than 1.0D. Fibers in the middle ink-receiving layer have a fiber fineness smaller than 0.3D. The middle ink-receiving layer is printed with a single-color or multi-color ink printed pattern. The fibers respectively in the upper surface fiber layer, the at least one middle ink-receiving layer, and the lower surface fiber layer are laid, sprayed, and formed into shape via heat pressing points by means of a single thermal bonding process. The area of recessed regions formed by the heat pressing points is 5-70% of the total area. The non-woven fabric web of the present invention can effectively prevent an ink transfer during use from causing potential problems, such as skin allergies.

Direct thermal recording media based on selective change of state
11370241 · 2022-06-28 · ·

Direct thermal recording media are designed to operate based on a thermally-induced change of state rather than a thermally-induced chemical reaction between a leuco dye and an acidic developer. The media use two types of solid scattering particles, one of which changes its state from solid to liquid during printing, and the other of which does not. The former particles, upon melting, fill spaces between the latter particles, thus eliminating or substantially reducing light scattering, which makes an underlying colorant visible at selected print locations where heat is locally applied. The media can provide high quality thermally-produced images at print speeds at least as high as 10 inches per second (ips).
