1: The material (paper) machine is normally open, whether it is good have a great relationship with your material on what is "good", the first in the previous paper, to fight loose, loose pile Changping catalog printing, the The material must be homogeneous, try not to have around, out of paper, or the printer is running, it will frequently appear early, late arrivals, twisted sheets or double sheet, causing the machine to stop running or stuffy car, we know boring car is very bad press, especially in Shanghai presses running at high speed, and parking is very frequently affect print quality, so material Shang Hao is the key! 2: stick (bar) rubber fault because we factory mainly do their own journals, so the paper generally relatively fixed catalog printing, there are 70g offset, 70g, 80g light coating, 95g, 105g, 128g, 157g high light double copper, for We often point the paper, light-coated paper is a more difficult to walk, because from the very nature, likely to cause trouble sticky rubber, usually adding some ink in the ink transfer, reducing the viscosity of the ink, but also There is a pull regulation must adjust the appropriate paper but did not pull a stick eraser will easily lead to failure, because the rubber in addition to the normal printing area, either by itself or by rubber on the outside, there will be accumulation of excess ink viscosity will be relatively large, easier to stick and tear the paper, resulting in sticky rubber failure, but sometimes the situation is serious, there is also a relatively benzene way is to wash the rubber! After the sticky rubber machines will continue to run, but the things that are out of print waste, so this kind of person will ask to see a sample must be ground, avoid the sticky rubber failure caused by excessive waste of paper! 1 large version large version layout structure layout structure is determined based on many factors Shanghai press size, plate size, paper size and structure of PDF page. In Signastation large version of software defined layout structure, including plate seams, paper seams, homepage (PDF page), binding wire, cutting wire and various markers. Wherein the home page layout for PDF located on a large version of the home page is divided into left and right page. Home page size is determined by the actual size (finished size) with bleeding size. When positioning 2.PDF page imposition based on PDF page structure, custom home in the imposition software type, and thus determine the method of page positioning, including the home page type, actual size (finished size) and bleeding size set set the page size and direction of the displacement. PDF page for different structures, there are two pages in Signastation in location solutions: automatic and user-defined. ① Auto: The system automatically based on PDF page into the page structure to a large version of a file, the rule is as follows: If the crop box contains pages in PDF (TrimBox), then the lower left corner of the crop box and left home the finished size angle alignment; finished lower left corner if no crop box (TrimBox) while cutting a box (CropBox), then the clipping box (CropBox) in the lower left corner of the home page aligned; if the crop box (TrimBox) and clipping box (CropBox) are not, and there is the bottom left corner MediaBox (MediaBox), then the lower left corner of the home media box actual size alignment. 3. Page Location instance to cross-page document. Finished assumed dimensions 210 × 285mm, PDF page for cross-page document, a single page is the Trilateral bleeding, on each side of 3mm, the cross-page PDF file size is 426 × 582mm, PDF page does not set the trim box (TrimBox). When this type of page Imposition two treatment methods: ① Method One: The cross-page file into single-page document on a single page document are set around the home page, and the displacement X, Y directions. After the split page is the Trilateral bleeding, size 213 × 291mm; shift left page is (X: -3mm, Y: -3mm), the displacement of the right page is (X: 0mm, Y: -3mm). ② Method two: do not split across pages of documents to locate the direct use of displacement. In this case the displacement value (X: -3mm Dalang product catalog printing, Y: -3mm) left page, right page of displacement (X: -213mm, Y: -3mm). For other PDF page structure requires the use of a different page positioning methods, which increases the imposition job variability and complexity, reduce reliability imposition job Hengli catalog printing, thereby affecting the finishing operations The normally. So, how to regulate the PDF page structure, simplify imposition jobs, improve the reliability and efficiency of prepress operations concern. Dongguan catalog printing company, beyond printing (certified), catalog printing by the Dongguan City, often beyond packaging products factory provided.
