1 PS version of the basic situation of aluminum plate
PS version of aluminum plate base is the choice of high quality aluminum alloy plate, ブラシ研磨プレートと電解研磨プレートの2種類の技術によるプレートベース処理。ブラシ研磨は機械研磨プレートです。, もっと早く使ってください, 近年はほとんど使われていない;最近では, electrolytic grinding process is often used to form uniform and dense sand layer on the surface of aluminum plate.Electrolytic grinding is the use of acid (usually hydrochloric or nitric acid) to erode the layout into a sand layer.
Brush grinding version and electrolytic grinding version of the internal quality of aluminum plate is not the same.Brush at home and abroad used 3103 アルミニウム合金, and electrolytic grinding plate usually 1050 aluminum alloy.Germany's HYDRO company pioneered the use
1052 grade aluminum alloy production aluminum roll PS version of the aluminum plate base.The 1052 aluminum alloy plate base strength is high, after electrolysis forms the sand mesh is careful, more and more by PS edition production factory welcome.
The apparent quality, flatness, thickness tolerance and shearing quality of aluminum plate will affect the sanding condition, thickness of oxidation film and printing overprinter precision of PS plate.At the same time, in the drum type
PS version of the production line, manufacturers for their own benefits, once the problem is found on the unwinding machine stop down the aluminum coil.Because one stop caused more than 100
As the m long aluminum plate base is scrapped, the cost of PS version increases, so PS
Version manufacturers of aluminum plate base quality requirements are quite strict.The printing
The factory to PS plate with aluminum base requirements are more stringent.Such as the provision of 01275 mm thick PS version, if thin, thick will affect the quality of the plate, affect the quality of printing and printing;The thickness of different volumes and sections of the same volume must be the same.
The best width tolerance of aluminum coil is 0, さもないと, the production of PS plate, 長さ (or width) tolerance can not meet the requirements.If there is a burr on the side of the plate, it will scratch the rubber of the printing roller and even hurt the hand of the plate maker.
