Solve The Problem Before Outputting The Printing Plate       In the process of packaging printing, it is often necessary to check the printing plate before printing.Solve The Problem Before Outputting The Printing Plate General inspection methods.Solve The Problem Before Outputting The Printing Plate This method is widely used in output centers and design companies. Solve The Problem Before Outputting The Printing Plate      Its main equipment is plate viewing table and densitometer. Densitometer is the key equipment for testing printing plate. Solve The Problem Before Outputting The Printing Plate       Its basic function is to read the tone percentage of mesh tone, so as to judge whether the size of mesh tone dot generated by plate making machine is correct.Solve The Problem Before Outputting The Printing Plate       For example, if the 40% gradient in the original drawing corresponds to the measured density on the printing plate […]

Improvement Of Scanning Quality Of Black-And-White Printing       In the face of a pile of black-and-white prints with poor quality but urgent need to be scanned, especially those of old newspapers and periodicals, either the paper turns yellow, Improvement Of Scanning Quality Of Black-And-White Printing       or the contents on the front and back of the paper penetrate each other due to the thin paper and the excessive ink permeability, which seriously affects the quality of scanning. Improvement Of Scanning Quality Of Black-And-White Printing      This paper introduces a method to ensure the scanning quality.Improvement Of Scanning Quality Of Black-And-White Printing 1. The color mode is adopted during scanning, so as to be as faithful to the original as possible, improve the accuracy, and provide conditions for smoothly removing the back graphics and texts that penetrate the front of the paper.Improvement Of Scanning Quality Of Black-And-White Printing 2. Using Photoshop software to […]

Curved Screen Printing Industry Has A Long Way To Go      Curved screen printing refers to screen printing on round shaped surfaces, such as various chemical bottles, medicine bottles, wine bottles, etc. most of them are cylindrical or almost cylindrical surfaces (the arc surface of flat bottles belongs to cylindrical surfaces), and there are few conical and spherical surfaces. Curved Screen Printing Industry Has A Long Way To Go       No matter what kind of surface, there is only one printing principle, that is, the silk screen printing surface should make a pure rolling motion with the screen. During the rolling, the surface is tangent to the screen to deal with the falling point of the rubber scraper, and its extension line always points to the center of the circle.Curved Screen Printing Industry Has A Long Way To Go       The design of curved screen printing machine is also based on this principle, which is generally driven by the toothed transmission of gear and rac […]

Several Ways To Improve The Printing Resistance Of Printing Plate       In the packaging and printing industry, it is often necessary to use various ways to improve the printing resistance of printing plates. So as to ensure that the template can be used for a longer time.Several Ways To Improve The Printing Resistance Of Printing Plate 1. Baking plate. After exposure, development and dirt removal, the PS plate is baked at 230-250 ℃ for a certain time to change the molecular structure of the original photosensitive layer and form a three-dimensional network structure, which becomes a solid graphic foundation.Several Ways To Improve The Printing Resistance Of Printing Plate 2. The positive PS version shall be kept away from light.Several Ways To Improve The Printing Resistance Of Printing Plate 3. The pH value of fountain solution shall be appropriate.Several Ways To Improve The Printing Resistance Of Printing Plate 4. Select the substrate with smooth surface and no impurities.Several W […]
