  Printing knowledge - field printing shows maximum saturation   Four-color printing is printed with CMYK(cyan, magenta, yellow, black) four-color overprint that you need. In the popular point, that is, you can use these four different colors to add up to get the color you need. Field printing refers to 100% color, such as 100% black is field black, and printing a large area of color block on printed matter. 1 There are a lot of people in the field saturation in the printing product color saturation do not know how to deal with, it is easy to cause unnecessary loss, theoretically, is to give full play to the maximum field density of #offset #printing #ink to achieve the maximum saturation. Although 95% of the dot will increase to 100% after printing, this is different from the effect generated by 100% field printing. 95% of the dot only reaches the field in 95% dot area, while 5% of the dot area has ink, but the ink #density is thinner. 95% of the dot increases to 100% in...

  Understanding Labelling Machines What is a Labelling Machine? A #labelling machine is a vital component of modern manufacturing, designed to automatically apply labels to various products and #packages. These machines use sophisticated technology to ensure that #labels are applied precisely and securely, which is crucial for branding, product identification, tracking, and regulatory compliance. The efficiency of labelling machines not only supports high production volumes but also ensures consistency and reliability in label placement, which can significantly impact product perception and safety.   Types of Labelling Machines Labelling machine  are categorized based on their automation level, application method, and the type of products they handle. The main types include #manual, #semi-automatic, and #fully automatic labelling machines, each serving distinct production needs. From rotary and inline machines to top and bottom, wrap-around, and front and back #labellers,...

  Discussion on solving the problem of no wrinkle in packaging bag glue In solvent-free #compound production, the #glue of #packaging bag is not used and wrinkle is a common and difficult problem affecting product quality. Through practical observation and analysis, this kind of problem involves multi-link factors, which need to be solved from the dimensions of process, equipment, environment and other dimensions, and the following combined with the actual production situation are discussed. First, glue does not wrinkle the cause of analysis (1) unstable glue ratio and supply Solvent free glue is prepared by a and b components according to a specific proportion, and the production is unstable, uneven coating and uneven mixing, which will make the proportion imbalance. For example, the fluctuation of glue supply, the output quantity of a and b components is often more and less, and the initial viscosity and curing characteristics of glue after mixing are changed. In addition, the co...

  What is white #ink# printing? Different from #CMYK color space ink, white ink has completely opaque covering characteristics. It can be mixed with a variety of other inks and special processes (such as fluorescent ink or glazing). According to the selection of the material, white ink can show a variety of unique effects. Whether it is small enterprises, medium-sized enterprises, large enterprises, or freelancers, graphic designers and artists, they can use white ink to create elegant and unique, personalized and visual products. Why is printing white ink important? When it comes to designing to stand out in dark, colored or transparent materials, white ink printing is crucial. But most printing presses cannot print white. The reason is that they use CMYK color models (green, magenta, yellow and black). White does not exist in CMYK, so printers leave these areas white and rely on the white of the paper itself. For standard white paper, this system works well. But what if you print...

  Analysis of the Causes of Pressure Faults in# Inkjet Printers 1 The ink line speed is normal, but there is pressure loss or it is too high (1) Check if there are any additives in the additive bucket and replenish them. Check the viscosity of the #ink to determine if it has become thinner (check if the printed characters are too light). Otherwise, the entire machine should be cleaned. For machines that have not undergone regular maintenance, the #filter elements and filter screens must be replaced. (2) Check if the shape of the breakpoint is correct and adjust the breakpoint. (3) Check whether the electrode of the nozzle is clean and clean the #nozzle. 2 Pressure loss fault caused by #pump motor failure (1) Pump motor failure leads to power loss, resulting in total pressure loss and pressure fault display. (2) The motor is disconnected from the pump. At this time, although the motor is rotating, the gear at the front end of the pump does not rotate, resulting in total pressure los...
