Arranging the color sequence in the printing process. In gravure printing on web materials, registration between different colors depends on the linear speed of the cylinders and the level of tension. Theoretically, the diameters of all plate cylinders should be exactly the same, and with modern polishing equipment this is entirely achievable. If there is any deviation in the diameters of the plate cylinders, the operator should place the plate cylinder with the smallest diameter in the first color unit, while the plate cylinder with the largest diameter should be

Carton production equipment is gradually making the transition from stand-alone machines to combined equipment and integrated equipment. Today, single-facer units, production lines and printing, slotting and die-cutting machines have become the key equipment for carton manufacturers; automated equipment such as fully automatic die-cutting machines, fully automatic creasing machines, fully automatic folder-gluers and fully automatic box stitchers is also increasingly becoming the equipment of choice for carton companies. However, some carton equipment manufacturers consider the issue only from the standpoint of having already developed certain patented technologies of their own, thinking only of the patented technology

Competition in the domestic corrugated box market is growing ever fiercer, and product price is the primary means of competition. How to seek greater profits within a slim profit margin, and how carton enterprises can reasonably lower production costs, have become the key issues. Voluntary activities to reduce corrugated box production costs have already been widely carried out. In fact, effectively reducing corrugated box costs requires only tackling a few minor details in the production process. How to keep the color consistent and the plate registration accurate in water-based ink printing on corrugated board

Technological innovation, as an important factor that keeps carton enterprises permanently dynamic and creative, plays a role that cannot be ignored in promoting the all-round development of the enterprise and the technological progress of the entire industry. The prerequisite for an enterprise to win in competition is the ability to provide physical products or services that are better in quality and cheaper than those of its competitors, which requires the enterprise to have solid technology. Yet at present, many carton manufacturers in China are weak in technological innovation capability. Continuous technological innovation is what enables an enterprise to always hold a leading

Because the ink rollers have aged, ink transfer is poor and the pressure between rollers cannot reach normal requirements; washing up is time-consuming, laborious and ineffective, and it wastes gasoline — even the two-stage wash-up method is not ideal. Over time, the rollers age even more under the action of residue and impurities, and the ink becomes even harder to wash off. So how can the ink rollers be cleaned thoroughly? The old method was to sprinkle No. X ink conditioner onto the rollers and then pour on gasoline to wash up by running a full page with the rollers engaged under pressure. But this

A method for correctly evaluating printing press performance — in order to carry out a correct evaluation, the following three requirements are put forward. Working performance mainly covers three indicators: registration accuracy, even and solid ink lay, and productivity. In multicolor printing, the precision with which the printed images overlap is one of the main technical indicators of working performance. In multicolor printing, the conveying, transfer and printing of the paper, whether at low or high speed, must all be guaranteed to take place at the specified position. For precision

Print E-commerce: More Than Just a Change in How Orders Are Taken Going the online transaction route can solve some challenges outside the printing field, such as controlling and allocating marketing funds and boosting brand influence. Online transactions bring more than a change in the way deals are done — they mean a great deal more. If you regard e-commerce merely as a simple change in the transaction model between you and your customers, once you actually start using e-commerce, you will find a whole host of problems

Concepts and classification of glass bottles and jars in China's glass packaging industry Hollow glass products that can be sealed with a cap or stopper and hold a measured quantity of various materials. They are widely used as packaging containers for beverages, alcoholic drinks, chemicals, pharmaceuticals, stationery and cosmetics. Glass bottles and jars are transparent, easy to clean, chemically stable, do not contaminate their contents, offer high airtightness and excellent storage performance, come in a rich variety of shapes and decorations, can be recovered and reused many times, and are made from abundant raw materials. But glass bottles and jars are prone to

Solutions to Problems with Printed Packaging Materials: To solve problems in printing, you must first have a clear understanding of the problem—what it looks like and how it differs from other problems; second, you should also understand what causes it and how these causes relate to one another. (For example, what is the primary cause and what is the secondary cause, and whether they are independent or related.) The problems described below all share one thing in common: they can be observed with the naked eye or with the aid of a microscope

The packaging machinery and equipment must be operated by designated personnel who are thoroughly familiar with the startup and bag-making procedures and able to perform simple instrument adjustments and parameter changes; instrument commissioning personnel must undergo strict training from the Yujie manufacturer, and be thoroughly familiar with instrument performance, working procedures, operating modes, operating status, and the troubleshooting and handling of common faults; unauthorized personnel are strictly prohibited from operating the computer instruments. Daily maintenance must ensure that the inside and outside of the computer instrument box are kept clean and dry; regularly check the wiring terminals for looseness or detachment
