Different between Screen Printing and Digital Printing

What's Screen Printing Screen printing is a printing technique whereby a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. Advantages of Screen Printing Highly cost-efficient process for bulk orders. Easy to print on specified areas. Huge range of printable fabrics such as wood, textiles, glass and more. Top-quality output. Long-lasting prints. Screen printing is the ultimate option for designs that need a top level of vibrancy especially when printing on dark background or product. Used for larger orders, the dye colour in screen printing equipment is applied thicker than the digital printing that results in brighter colour even on darker shades. What's Digital Printing Digital printing is the process of printing digital-based images directly onto a variety of media substrates. There is no need for a printing plate, unlike with offset printing. It usually refers to professional printing wh

Starting Frequency (Flat Screen Printer)

According to the survey, the starting frequency of the Flat Screen Printing Machine can’t be too high. Since the speed of the equipment is zero at the start of the machine. In the starting process, in addition to overcoming the load resistance torque, the electromagnetic torque overcomes the inertial masking of the rotating part. When the burden on the equipment is heavier than continuous operation, what effect will the startup frequency be too high? Let's take a look at it below. If the pulse frequency is too high at start-up, the speed of the rotor will not keep up with the speed at which the stator magnetic field rotates, so that the position where the first step is completed is far behind the equilibrium position, and the rotor speed is not increased much in the subsequent steps, while the stator magnetic field is still It rotates forward at a speed proportional to the pulse frequency, so the distance between the rotor and the equilibrium position becomes larger and large

Basic Information (Open Type Rotary Screen Printer)

Open Type Rotary Screen Printing Machine adopts a continuous rotary seamless cylindrical screen to print. According to the arrangement of the rotary screen, it can be divided into three types: vertical, horizontal and radial rotary screen. Among these, the horizontal rotary screen printing machine is commonly used. The rotary screen printing machine is composed of a device for feeding, printing, drying and discharging the cloth. The mechanical components of the printed part can be divided into printed rubber guide tape, rotary screen drive device, rotary screen and printing scraper frame, flower arrangement, rubber belt washing and wiping device, and printed fabric pasting and slurry pumping system. When printing, when the printed fabric is in contact with the rubber guide tape, since the rubber tape is coated with a layer of adhesive glue in advance, the printed fabric is pressed against the top of the printed fabric without moving. The printed fabric enters the d

Some Tips of Operating Flat Screen Printer

Flat Screen Printer uses a flat screen version and prints on a flat substrate, generally, the squeegee of which presses the plate horizontally and the machine changes the substrate through the plate. However, for many new customers, though we purchase it, we do not know how to use. Now, I would like to introduce the operation process to you. In the process of using the machine, we need to be careful to avoid mechanical damage and electric shock all the time. Some tips are as follows. First, clean the Flat Screen Printing Machine and workplace. Don’t place any objects on the worktable. Second, check the screen version, and the four corners of the screen frame and the surrounding of the picture are sealed with a side back adhesive to avoid leakage during printing. Third, prepare and set up fixtures according to product process requirements and technical specifications to confirm silk-screen. Fourth, fix the frame on the clamp and adjust the distance between the substrate and th

Overfeeding Technology of Hot Air Stenter II

Analysis of some important proper nouns: Overfeed: It is an action process that provides a specific proportion of the required amount according to the requirements of the next step. Specific ratio: There are positive, negative or zero, that is, positive overfeed, negative overfeed or zero overfeed. Requisite Amount: which is expressed as speed, flow, quantity, quality, etc. The requirements for the next step: depends on the purpose of the treatment to be achieved. The amount of overfeeding: it is by the super-feeding mechanism through the data relationship between the front and back of the mechanism. Measurement and Control Instrument: It is the necessary matcher. 1. The Hot Air Stenter setting machine needs more fabrics to be fixed on the needle board in advance in order to eliminate the longitudinal stretching amount of the fabric before the dyeing process and meet the requirements of customers. For example, the feeding mechanism runs 120M per minute, and the needle plate

Heat Setting of Hot Air Stenter Machine I

The Hot Air Stenter Machine, a piece of equipment in the textile printing and dyeing factory, is used for stretching and tensioning the fabric by heating and stretching. The heat setting of the fabric is usually a process in which the fabric is kept at a certain size and heated under a certain temperature and humidity for a certain period of time and then cooled. Therefore, the main process conditions for heat setting are nothing more than temperature, time, tension, etc. First, the temperature Temperature is an important factor. Since the fabric is heat-set, the degree of wrinkles that have been eliminated, the improvement of surface flatness, the thermal stability of the fabric and other performances are closely related to the heat setting temperature. Second, the time The setting time is another major process condition for heat setting. After the fabric enters the heating zone, the heat setting can be divided into the following sections: The time required to heat the fabr

How to Purchase Flat Screen Printer

LiCheng Flat Screen Printer is mechanical equipment widely used in the textile printing and dyeing industry, which is very popular among the printing machines. Why is the flat screen printing machine so popular with customers? Is the flat screen printing machine really good? The flat screen printing machine has good quality and low price, with high speed and high efficiency. We can go straight into Zhejiang Licheng Group in detail. How to purchase Flat Screen Printing Machine ? 1. Pay attention to the brand In fact, famous brands maybe not good, niche brands may be not bad, but many consumers hold the view that famous brands are more trustworthy than unnamed brands. After all, if an enterprise grows up from a young age, it should pass the market's assessment. If the technology is not high and the quality of the machine is not good, it is difficult to gain a market share. 2. Pay attention to printing speed As the saying goes: time is money. The flat screen p
