摘要： PURPOSE: A method is advantageous in reducing airborne debris and vapors during laser imaging, in increasing the speed of laser imaging, and in providing excellent cleanability and image quality. CONSTITUTION: Provided are methods of imaging a wet positive working lithographic printing member comprising the steps of providing a positive working printing member comprising a substrate(106), a hydrophilic layer(104), an infrared-absorbing layer, and, optionally, an ink-accepting surface layer(102); exposing the printing member to infrared layer imaging in an imagewise pattern removing by ablation greater than 10% by weight, and most preferably none of the infrared-absorbing layer and optional ink-accepting surface layer; and removing with water the laser-exposed areas of the infrared-absorbing layer and optional ink-accepting surface layer to reveal the underlying hydrophilic layer. The printing member may further comprise a primer layer underlying the infrared-absorbing layer with an adhesion-promoting agent present in the primer layer. Also provided are methods of preparing a wet lithographic printing member and wet positive working lithographic printing members.

摘要： Provided are methods of imaging a wet positive working lithographic printing member comprising the steps of providing a positive working printing member comprising a substrate (106), a hydrophilic layer (104), an infrared-absorbing layer, and, optionally, an ink-accepting surface layer (102); exposing the printing member to infrared layer imaging in an imagewise pattern removing by ablation greater than 10% by weight, and most preferably none of the infrared-absorbing layer and optional ink-accepting surface layer; and removing with water the laser-exposed areas of the infrared-absorbing layer and optional ink-accepting surface layer to reveal the underlying hydrophilic layer. These methods are advantageous in reducing airborne debris and vapors during laser imaging, in increasing the speed of laser imaging, and in providing excellent cleanability and image quality. The printing member may further comprise a primer layer underlying the infrared-absorbing layer with an adhesion-promoting agent present in the primer layer. Also provided are methods of preparing a wet lithographic printing member and wet positive working lithographic printing members prepared according to the methods of this invention.
摘要翻译：本发明提供了对湿法正型平版印刷元件进行成像的方法，该方法包括以下步骤：提供包括基材（106），亲水层（104），红外线吸收层和任选的吸墨剂表面层（102）; 以大于10重量％的消融除去成像图案的红外层成像，最优选没有任何红外线吸收层和任选的油墨接受表面层; 并用水除去红外线吸收层和任选的受墨表面层的激光曝光区域以显露下面的亲水层。这些方法有利于减少激光成像过程中的空气碎片和蒸汽，提高激光成像的速度，并提供出色的清洁性和图像质量。印刷部件可以进一步包括在红外线吸收层下面的底漆层，其中在底漆层中存在粘合促进剂。还提供了制备根据本发明方法制备的湿式平版印刷部件和湿法正型平版印刷部件的方法。＆lt;图像＆GT;
