subject: Specifications Are Not Allowed To Die Indentation Caused By The Eight Factors Of Analysis - Die [print this page] Die indentation is supporting the production of packaging and decoration printing technology, widely used book covers, trademarks, labels, cartons, boxes and other products of the indentation and cutting molding. Indentation by die processing, can print up beautiful, the applicable technical requirements. Therefore, the effect of die indentation how, will directly influence the product quality and marketing image.
Print Network HC Die indentation is Package Decoration Print Supporting the production process, widely used in books and covers, Trademark , Label , Carton , Box Products such as indentation and cutting molding. By cutting indentation process, can print up beautiful, the applicable technical requirements. Therefore, the effect of cutting indentation How will directly affect the product quality and market image. However, the production of a variety of adverse factors, resulting in the phenomenon of cutting indentation size are not allowed to have occurred, to the following eight areas.
1, after mounting of the thickness of semi-finished products due to changes in specifications are not allowed to pages After mounting of semi-finished products
printing, the thickness will affect the finished product after cutting indentation layout and, in particular mounting of Corrugated paper Board, because of the increased thickness of the product after cutting indentation shape, layout position bias error will occur. Therefore, taking into account printing make-up products to increase the thickness after mounting of refolding, the printed page should be located in the correct location.
2, upper and lower semi-finished paper lamination allowed to cause positioning errors
Printing surface and non-printing surface mounting of two layers of cardboard, if not allowed to make non-printing surface of paper protruding surface of the rules printed on paper side is bound to result in semi-finished die-positioning error. That the daily production, whether by hand or mechanical automatic laminating laminating, will inevitably lead to mounting of the phenomenon are not allowed, to prevent After mounting of the rules of non-printing surface of paper protruding edge phenomena occur, usually in the printing should according to the characteristics, will be printed before the semi-side rules and regulations edges add up 3? 6mm margin ranging from trimming, laminating so, it will be the rule of non-print side edges due to be mounted within a reduced number of millimeters paste, which can effectively prevent the rule of non-printing surface of paper protruding edge phenomena occur, to ensure the accuracy of product die.
3, cardboard obvious cause curling semi-positioning allowed When the semi-finished products appear curly
, Qi Qiao situation, especially after mounting of the corrugated cardboard after the semi-embossed plates together on the pressure, the paper did not even touch with the die-to tilt the paper and the layout on the first section of rubber or sponge contact, so easy to make semi-finished sheets embossed on the plate to slip, resulting in products are not allowed to die. Therefore, to maintain good flatness board, is to improve the precision of semi-finished cutting an important part. To control the smoothness of corrugated board, the key is to control the production process of a good single machine, to select the water content was close to the corrugated paper and cardboard for laminating, and good control single machine speed and temperature, to prevent corrugated noticeable curl affect the precision die cutting products.
4, paper specifications are not allowed to stretch variation caused by layout
The paper semi, if the paper with poor stability, resulting in the printing process can cause significant variation of moisture content, especially after calendering products, such as coating or lamination processing, by the inch: heat or absorb water, so that semi-flexible change occurs, so that when cutting indentation, the layout position of printed materials will be any bias. This, the solution is: try not to just produce the paper used, but should be placed just a few months of paper produced, the relative balance between them and the printing conditions and then put into use, so the relatively small number of deformation coefficients. On high precision products, should fully consider the calendar, coating, laminating and other process of deformation coefficient, in print layout make-up when the appropriate adjustments in place. In addition, to control the good paper library, coating, calendering, coating, laminating and die cutting shop temperature and humidity, temperature and humidity of the production process, not an obvious disparity between high and low, so as to ensure that the location of die indentation and the exact specifications.
5, grain of the paper the wrong direction with the indentation caused by the location of closed die
Vertical and horizontal direction, there is a general layout is put together by a number of small version of the composition of that if the most vulnerable to changes in the paper horizontal stretch silk thread to the direction of the printing and more make-up structure layout, do not die easily result standard. Therefore, the layout has been put together for the multi-version structures, the paper should be vertical and subject to printing, to better guarantee the accuracy of cutting.
