Abstract
(EN)
A drawing method according to an embodiment of the present disclosure comprises: when performing drawing with respect to a thermosensitive recording medium in which a light transmission member having an irregular shape in a plane is disposed above a recording layer, causing an optical compensation body having one surface with a shape fitting with the irregular shape of the light transmission member and another flat surface opposing the one surface to be disposed on the light transmission member with the one surface facing the light transmission member; and irradiating the thermosensitive recording medium with laser light via the optical compensation body.
(FR)
Selon un mode de réalisation, la présente invention concerne un procédé de dessin comprenant les étapes consistant à : lors de l'exécution d'un dessin sur un support d'enregistrement thermosensible dans lequel un élément de transmission de lumière ayant une forme irrégulière dans un plan est disposé au-dessus d'une couche d'enregistrement, amener un corps de compensation optique ayant une première surface dont la forme correspond à la forme irrégulière de l'élément de transmission de lumière et une autre surface plane opposée à la première surface à être disposé sur l'élément de transmission de lumière, la première surface étant orientée vers l'élément de transmission de lumière ; et irradier le support d'enregistrement thermosensible d'une lumière laser par l'intermédiaire du corps de compensation optique.
