In the field of product packaging and identification, label printing is very important. Labels carry key information. To enhance the attractiveness of products, the following will introduce the key points of label printing in detail.
First of all, the content of the label should be clear, including necessary information such as product name, specifications, ingredients, instructions for use, production date, shelf life, etc. At the same time, the overall layout design should be carried out to ensure that the text is clear and readable, and the pattern and color are coordinated to match the brand image.
Paper materials:Coated paper labels have good color expression and smooth surface, and are often used in cosmetics and daily necessities labels; kraft paper labels have high strength and good toughness, and are suitable for industrial products and express package labels; thermal paper labels do not require ink, and display text images by heating and discoloring with a thermal head, and are often used in supermarket cash register receipts and logistics labels.
Plastic materials:Polyester labels are chemically resistant, dimensionally stable, and highly transparent, and are often used for electronic product labels; polypropylene labels are soft, water-resistant, and grease-resistant, and are suitable for food packaging labels; polyvinyl chloride labels are flexible and low cost, but are less environmentally friendly.
Letterpress printing:The image and text on the printing plate are raised, and the ink is transferred to the substrate. It is suitable for printing simple and large quantities of labels with low cost.
Gravure printing:The image and text part of the printing plate is concave, and the printing is done after the ink is filled. It has bright colors, rich layers, bright colors, long-lasting, and wear resistance, but the plate making cost is high and the flexibility is poor.
Digital printing:Directly transfer digital files to printing equipment for printing without plate making. Digital printing is highly flexible, can achieve personalized customized printing, and can quickly respond to market demand.
Debugging equipment:According to the selected printing method, the label flexo printing machine should be comprehensively checked and the parameters of the printing machine, such as ink supply, printing pressure, printing speed, etc., should be adjusted to ensure stable printing quality.
Printing:Printing: Put the prepared materials into the printing machine and start printing. During the process, sampling inspection is required to check whether the color is accurate, whether the graphics are clear and complete, whether the overprint is accurate, whether there are stains, and timely adjustments.
Die Cutting:Use a die-cutting machine to cut the printed material into individual labels according to the shape and size of the label design.
Lamination:In order to improve the wear resistance, water resistance and glossiness of the label, lamination can be performed. Glossy film and matte film are available.
A label flexo printing machine uses flexographic printing technology to produce labels. It involves transferring ink onto a substrate using flexible relief plates. These machines are widely used in the label industry for their efficiency and ability to handle high-volume production.Flexographic printing machine is highly efficient, versatile and cost-effective.
Printing labels requires the design of labels, material selection, printing process, printing operation and post-press processing. It is necessary to fully consider factors such as product demand, cost budget and market positioning to produce high-quality labels that meet the requirements of product information communication and attract consumers' attention.If you need a label flexo printing machine please contact us.
