Solutions To the Problems Of Inaccurate Overprint And Uneven Ink Color Of Printed Matter

Solutions To The Problems Of Inaccurate Overprint And Uneven Ink Color Of Printed Matter      In the packaging and printing industry, offset printing is the main printing mode of printing enterprises. Due to the failure of the output system, offset lithography is the main reason for the incorrect printing of printed materials, uneven ink color, unable printing and delayed delivery. This is one of the most common thorny problems for printing workers.Solutions To The Problems Of Inaccurate Overprint And Uneven Ink Color Of Printed Matter. 1、 Two or more sheet feeding faults.       The paper is uneven and the edge is warped. When the air flow from the loose paper blowing port contacts the paper edge, the paper edge warps into an arc angle, and the air flow is divided into two parts. Solutions To the Problems Of Inaccurate Overprint And Uneven Ink Color Of Printed Matter.      One part of the air flow makes the paper lift up, while the other part of the a […]

Performance Introduction Of Screen Ink Printability

Performance Introduction Of Screen Ink Printability      In the packaging and printing industry, screen printing ink should meet the requirements of storage, printing, durability, economy and safety, but in terms of technical performance, it is mainly printability and application applicability.Performance Introduction Of Screen Ink Printability       Printability is also called operating characteristics. Generally speaking, the ink should be able to leak smoothly from the printing plate to the substrate without blocking the silk screen, dry quickly on the substrate, and have good embossing reproducibility. The influencing factors of Printability are very complex, with about 60 variables. Here are some main attributes.Performance Introduction Of Screen Ink Printability.       One of the characteristics of ink is that it hinders its relative flow viscosity. The unit is Pascal second (PA · s). The viscosity of screen printing ink is in the middle or high amon […]

Introduction Of Printability Of Aluminum Foil Paper

Introduction Of Printability Of Aluminum Foil Paper       In the packaging and printing industry, printing on paper with aluminum foil on the surface is called aluminum foil paper printing. There are two kinds of aluminum foil: gold foil and silver foil. Aluminum foil printing products are mostly used for packaging decoration, which can make the packaged products more noble and gorgeous, so as to improve the grade of products.Introduction of Printability of aluminum foil paper        Therefore, the printed matter printed with aluminum foil paper has a brighter visual effect than other paper printed with gold and silver processing technology. The history of printing on aluminum foil paper is not long, and it is still very uncommon at present, because aluminum foil paper has obvious printability compared with other ordinary paper.Introduction of Printability of aluminum foil paper 1. Printability of aluminum foil paper        Aluminum foil paper is a kind of non absorbent paper. It is ma […]

Harm Of Static Electricity On Paper To Printing

Harm Of Static Electricity On Paper To Printing      In the packaging and printing industry, sometimes paper with static electricity will bring a lot of trouble to printing.Harm Of Static Electricity On Paper To Printing.      First, the paper cannot be touched. Under the action of static electricity, the paper and paper are firmly absorbed, there is deviation, and it is difficult for air to enter between the papers. If you want to collide, you will sometimes pull them apart one by one, wasting time.Harm Of Static Electricity On Paper To Printing.       In the printing process, due to electrostatic attraction, single sheets of paper are firmly pasted together, sometimes two, sometimes several, sometimes a pile of paper can not be separated, and the paper separation suction nozzle can not absorb the paper. When the brush is pressed heavily, it often produces broken tension and empty tension; Harm Of Static Electricity On Paper To Printing.     […]
