摘要	A printing apparatus and method for aligning special effect flakes is disclosed. The flakes field orientable and have an absorption band of wavelengths and a reflection band of wavelengths and are dispersed within in a viscous paste-like ink. The absorption band of the flakes is more absorbing than reflecting and the reflecting band is more reflecting than absorbing. A laser diode array is provided for generating beams of light positioned to irradiate the paste-like ink coating on the substrate so as to lessening the viscosity of the paste like ink by irradiating with light. Preferably at least 45% of the optical power of the one or more beams of light is in the absorption band of the flakes. After the flakes are heated to lessen the viscosity of the ink, a magnetic field is applied so as to orient the flakes within the ink.
其他摘要	公开了一种用于对准特殊效果薄片的印刷设备和方法。薄片场可取向并具有波长的吸收带和波长的反射带，并且分散在粘性糊状墨水中。薄片的吸收带比反射更具吸收性，反射带比吸收更能反射。提供一种激光二极管阵列，用于产生光束，该光束定位成照射基板上的糊状油墨涂层，从而通过用光照射来减小糊状油墨的粘度。优选地，一个或多个光束的光功率的至少45％处于薄片的吸收带中。在加热薄片以减小墨水的粘度之后，施加磁场以使薄片定向在墨水中。
主权项	A method of printing and aligning special effect flakes, such that at least some of the printed flakes orient along field lines of an applied field, the method comprising the steps of: a) providing a paste-like ink, comprised of a carrier having flakes therein having an absorption band of wavelengths and a reflection band of wavelengths, wherein the absorption band is more absorbing than reflecting and wherein the reflecting band is more reflecting than absorbing and wherein the flakes are comprised of at least a layer of field orientable material; b) applying the paste like ink by printing said ink upon a substrate; c) lessening the viscosity of the paste-like ink by irradiating with one or more beams of light having an optical power, wherein at least 50% of the optical power of the one or more beams of light is in the absorption band of the flakes or the carrier; and, d) reorienting the flakes using the applied field to form the image.
