Problems solved by technology

Although some high-end printing equipment has been equipped with CIP3 / CIP4 interface to realize the automatic setting of ink volume, but at the same time must use direct plate-making mechanism plate, but most of the printing equipment environment does not have the conditions to be equipped with this interface, quite a few printing factories No direct plate-making machine has been purchased, and the ink volume setting has become the bottleneck of the printing process. Therefore, how to determine the ink supply of the printing machine has attracted people's attention, and its improvement is imperative

Embodiment

[0049] 1. Printing conditions

[0050] Printing machine: Heidelberg CD102; Paper: Jindong brand (157g) coated paper; Ink: Tiens brand; Temperature: 25°C; Humidity: 60%;

[0051] 2. Prepare the manuscript for calculation

[0052] First, convert the files generated after imposition into PDF format, and then use Photoshop software to convert them into images in TIFF format with a resolution of 81.28DPI, which is used as the original data for ink volume calculation;

[0053] 3. Calculate the ink volume value of the ink area

[0054] Start the ink volume calculation software in the ink area, first set the initial conditions for the calculation of the ink volume in the ink area according to the actual conditions. The image resolution is 81.28dpi, and the maximum layout is 1030mm. %, and then use the ink volume calculation model to read in the original, and use the calculation model to generate ink volume data. The computer steps performed and the calculated values ​​​​are as follows...

Abstract

The invention relates to a method for determining ink feeding amount of a printing machine, which can effectively solve the problem of the ink feeding amount of the printing machine. The method comprises the steps that a paste-up software is used for pasting up images, graphs and files onto one layout to create a file in the format of PDF and the PDF file is subject to a gridding processing through the Phtoshop software to generate a color TLFF image; the mathematical modeling is performed by utilizing the parameter of the printing machine and combining the image color information provided by the color TLFF picture; the parameter and information are calculated to obtain the ink bond open value of each ink area on each color plate and the angle value of the distributer so as to build the computation model of ink area and ink amount; the computer programming is hired to obtain the ink amount generation program and the ink amount generation program is executed by the computer to obtain the atlas of ink area and ink amount; the printing machine is set to carry out the printing according to the atlas of ink area and ink amount. In the whole process, the production of datamation and standardization with convenient operation and good quality of the printing product is realized, thus saving the material and providing huge economic and social benefits.

Description

1. Technical field [0001] The invention relates to a printing method, in particular to a method for determining the amount of ink supplied by a printing machine. 2. Background technology [0002] In recent years, the digitalization and automation of printing machines produced at home and abroad have been significantly improved. The ink supply of most printing machines can be set through numerical values, according to the opening value of the ink key in the ink area and the size of the ink transfer roller corner. To adjust the amount of ink supplied to the printing plate, but under the current technical conditions, the numerical setting of the ink amount in the printing production process still depends on the work experience of the leader, and for the inexperienced leader, the setting of the ink amount is The bottleneck in the printing process often lengthens the production cycle due to repeated adjustments to the ink supply, and also reduces production profits due to the inc...
