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). There are two pages of such treatment when Imposition: ① one: the cross-page file into single-page document printing brochures paper, single-page documents are set around home printing brochures, and X, Y displacement direction. 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 values ??(X: -3mm, 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 jobs, thereby affecting the normal finishing operations. So, how to regulate the PDF page structure, simplify imposition jobs, improve the reliability and efficiency of prepress operations concern. Pictures, color and line, I want to place picture frame, can not exceed the size of the production, but also to avoid using white color. Pictures of the words in the word using the system, to be converted into a description of the frame or curve, in addition there is no overlap between the note and skip between words, black text can not be used to fill overprint. If printing the same document in different secondary, there will be differences in color and normal color degree should be within 10 percent. If the design documentation tools are used CoreIDRAW9.0 Chinese version, Mac documents designed to be replaced by PC format. Also, if there are broken or do not want to print the Company can not render the brochures printed, painted himself in the input or graphics, the frame thickness greater than 0.1mm. Process characteristics lithographic press operation control such that the drive inverter motor drive can well be applied to the printing press, to meet production requirements, we must first understand the characteristics of the press operation control technology, its inverter function of what made requirements, and then choose what type of drive, and how to transform specific docking original line. Sheet-fed offset printing press is running between the rollers, the tooth row, institutional cooperation and coordination by the mechanical action of the connection, the control of the main drive motor by the motor via a belt drive, gear drive, chain drive driven machine, it control the running of the whole machine. In the mechanical adjustment, inspection, installation and removal PS plate and blanket, clean the machine, you will need to manually point the way to control the machine forward and reverse drive operation, about 4r / min speed is appropriate. During the Shanghai printing pause, in order to ensure PS version is not damaged, the ink is not dry, to make the machine at the same speed of the long car running. When the machine starts formal print production, there is an initial speed of about 3000 rpm / hour. When the feeding machine feeding can begin to accelerate the machine at a higher speed production, generally from 6000 to 8000 rev / hour. In order to meet the requirements of different production speeds, via a speed potentiometer for speed adjustment, the actual value of the speed can be indicated by the speedometer. Down from a high initial printing speed of printing, there are two cases. First, the manual button slow down, the other is the printing process paper fault is detected, such as crooked sheets, no paper, double sheet, etc. so that automatic press deceleration, the parts to be made accordingly coordinated action, such as from pressure, water , from Mexico, stop feeding and so on. At the end of production, stop button is pressed, the machine accordingly to free stop mode is smoothly stopped. Furthermore album brochures printed, in order to ensure personal safety in dangerous parts of the printer is attached to safety switch or emergency stop button, as long as these switching operation, no matter what state the machine, must immediately cease, the whole machine emergency brake. Brochures printed paper, Liaobu printing brochures, manuals printing by the Dongguan City, often beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) strong, credible, in Dongguan, Guangdong paper printing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead beyond printers and you hand into the brilliant, for a better future!
