A cover film for covering a hard copy produced by sublimation thermal-transfer image-forming has an anti-contamination layer with one side for contacting the hard copy, and a gas-impermeable layer provided to the other side of the anti-contamination layer.

Cover film for sublimation thermal-transfer hard copy

A printer comprises image signal generating element for repeatedly generating one line of image signal, compare element having a plurality of reference levels and comparing the image signal with selected one of the reference levels, thermal head element having a line of heating elements for printing one line of image signal, current supply element for supplying currents to the heating elements in accordance with the compare results, setting element for setting a continuous energization period for supplying the current to the heating elements from the supply element, and control element for controlling the supply element to provide a first period during which the energization of the heating elements in a first group is inhibited and a second period during which the energization of the heating elements in a second group are inhibited.

Thermal system image recorder

A thermal transfer recording system comprising a supply cartridge including a case and an image forming sheet and an ink sheet housed in the case, taking-out means for taking out the image forming sheet and the ink sheet from the supply cartridge and print means including a thermal head for printing on the taken-out image forming sheet by the taken-out ink sheet.

Thermal transfer recording system

An image recording apparatus provided with a thermal head, records a two-dimensional image on heat-sensitive recording paper by controlling ON times of heating elements dots. The heating elements dots are divided into a plurality of blocks which are time-divisionally driven to print one-line pixels without white lines.

Image recording apparatus with thermal head

A recording method comprises the steps of selectively applying heat to individual heat sensitive color forming sheets each comprising a supporting sheet and a transparent color forming layer on the supporting sheet, which color forming layer is adhesive and develops a color under the action of heat but the colors developed in the individual layers being different from each other, thereby forming monochromic images in different colors on the individual color forming sheets; and separating each color forming layer with the formed monochromic image from the corrresponding supporting sheet and laying the separated individual layers on a common base sheet successively in layers making use of their own adhesiveness.
