Some faults can be identified by sound. By observing abnormal sounds, we can determine the location, extent, and cause of the fault so that we can take timely measures. Label Source takes appropriate action based on the sound. Here are a few examples of how to identify the sounds of common faults: 1.The paper feeder made a slipping “squeak” sound. This is caused by severe wear and tear on the nozzle during prolonged use, resulting in a smooth suction surface. It could also be due to poor airflow, insufficient suction, or paper that is too thick, slippery, or stuck together. The following methods can be used to address the issue: ① Apply a rubber ring to the nozzle; ② Scratch the nozzle surface with a saw blade or sandpaper to increase friction; ③ Clean the feeder and clear the airflow path; ④ Remove any buildup inside the blower; ⑤ Treat the paper accordingly. 2.There is a “chichi” sound from both mouths of the paper separating nozzle. This could be caused by several reasons: First, improper adjustment, resulting in misalignment of the suction holes; second, the piston fixing screw automatically shifting outward, causing a change in the angle of the two......

There are eight factors that directly affect the slow drying of printed labels, here Label Source explains as below： 1.Ambient temperature: Low ambient temperature or high humidity will slow down the drying of ink. 2.Ink properties: Generally speaking, inks made with organic pigments dry slower than those made with inorganic pigments, thinner binders dry slower than thicker binders, and inks with higher oil content dry slower than those with lower oil content. 3.Diluents and thinners: Both diluents and thinners have the property of inhibiting ink drying, so they should be added in small amounts. 4.Paper properties and structure: If the paper is acidic, the ink dries slowly. A rough paper surface, loose structure, high permeability, and low sizing will promote ink drying, while the opposite will slow down the drying process. 5.pH value of dampening solution: Low pH value of dampening solution: The concentration of hydrogen ions (H+) in the dampening solution is very high, which will cause a displacement reaction with the metal salts in the drying oil, thereby inhibiting the drying of ink on the paper surface. 6.Printing Moisture: In the label printing process, if the printing plate has too much moisture, it will not only cause the......

The issue stems from an excessively large clearance between the roller neck and the support sleeve of the label printing machine’s rubber roller, or a poor fit between the support sleeve and the adjustable track surface. Some have also suggested a quality defect in the rubber roller itself, affecting its normal operation. To address this, we inspected and analyzed each mating surface and dimension of the support sleeve, and all results were normal. We also measured the roller’s circular runout and diameter at multiple points using a dial indicator on a lathe. The measurements showed that the circular runout and diameter tolerances were within the first-class product range. Therefore, it seems that the dimensions of the coating machine’s components and the assembly dimensions, as well as the specific rubber roller itself, are not the problem. To address the issue of excessive vibration affecting the normal operation of the label printing machine’s rubber rollers, we tested a worn-out, scrapped rubber roller on the varnishing machine. The old roller ran smoothly without significant vibration, indicating that the excessive vibration of the new roller was primarily due to inherent quality defects. Based on this, we conducted further investigation and analysis, ultimately concluding that......

Printing processes can cause the coating film formed on the coating rollers to be easily broken and cracked; improper setting of coating head process parameters can lead to poor coating transfer between rollers, thus affecting coating quality. To address these issues, the following measures should be taken in actual production. 1.Add a screening system to the paint delivery pipeline： In view of the impurities and bubbles contained in the paint, the paint conveying process was modified and a screening system was added between the working tank and the working plate to screen out the impurities and coarse spacer particles mixed in the paint, thereby improving the quality of the paint and improving the film-forming properties of the paint. 2.Eliminate metering roller scraper： In view of the impurities and bubbles contained in the paint, the paint conveying process was modified and a screening system was added between the working tank and the working plate to screen out the impurities and coarse spacer particles mixed in the paint, thereby improving the quality of the paint and improving the film-forming properties of the paint. 3.Reasonable adjustment of coating head process： Reasonable and appropriate roller gaps, speed ratios, and wiping ratios have a significant......

Solve printing problems for printing companies and promote the industry’s development towards high-quality printing. “LabelSource Label Classroom” Nationwide Offline Prepress Training Activities — Solve printing problems for printing companies and promote the industry’s development towards high-quality printing. A nationwide offline prepress training event, jointly organized by “LabelSource Label Classroom” and “Brother Niu’s Prepress Training,” has been successfully held in seven venues: Qingdao, Jinan, Cangzhou, Shenyang, Tianjin, Henan, and Xi’an. This training event aims to provide high-quality, professional prepress skills training for printing companies, addressing some of the difficulties and pain points encountered in prepress production and printing processes. Group photo of participants at the “LabelSource Label Classroom” Jinan station. This training activity provided in-depth yet easy-to-understand explanations and case studies on topics such as improving customer satisfaction and loyalty, achieving beautiful printing results, four-color and spot color printing, and optimizing the printing process. Through a combination of theoretical instruction and practical exercises, the training helped participants further master and apply prepress processes and technologies, thereby improving production efficiency and product quality. Brother Niu provided a clear and concise explanation for the participants. A key figure in this event was Brother Niu, a seasoned instructor. As an expert with many years......

To our valued customers and friends: Label Source sincerely thanks our customers for their strong support at the exhibition. As the saying goes, “One should always remember the source of one’s blessings.” With a grateful heart, Label Source extends its warmest greetings and heartfelt thanks to you. Label Source has weathered over a decade of trials and tribulations, and we have witnessed its growth, progress, and development together. From Full-Rotary CI letterpress printing presses and multi-functional screen printing presses to today’s Inline Flexo printing presses and Digital + Flexo Hybird printing presses, all have earned a renowned reputation in the industry and a good track record. At the same time, we are continuously researching and improving our process procedures. Our precise and efficient “CCD fully automatic vision registration system” not only boasts high registration speed and accuracy, but also features a thoughtfully designed “shared photocell” function to adapt to various printing scenarios. Our “servo-controlled non-stop unwinding and rewinding system” utilizes an AB roll design for both the unwinding and rewinding sections, allowing for automatic roll changing simply by setting the roll diameter or length. In addition, we offer a wide range of other printing process components (such as front and......
