PVC printing sheet uses one two three There are three main factors to consider when making wide-format printouts on PVC: consistency in PVC manufacturing, thoughtful handling of PVC, and continued attention to static electricity. Although the printer has taken steps to address the latter two, the best way is to have the substrate manufacturer pay close attention to these materials before they are delivered to your store. Save material, time and money from the right product. 1F production consistency The first step in choosing a PVC sheet is to check the consistency of the manufacturer's process (in formulation, extrusion, and temperature). For wide-format printing, PVC manufacturers need to improve the quality and consistency of their PVC products. Sheet defects are not noticeable in screen printing applications, primarily because the applied ink layer is much lighter. The consistency of surface finish, density, color, thickness tolerance and transparency has become a key parameter. A good PVC for printing starts with a recipe. For inkjet printers, it's important to keep the formula consistent, and small changes in composition (sometimes to improve the economics of production) may change the characteristics of the print, requiring expensive changes in the print shop. . When choosing a substrate brand, consult with the manufacturer and distributor about the recent changes in the formulation and its impact on your business. It is also important to ensure that the PVC is produced in a temperature controlled environment. The same formulation will produce different properties when manufactured at a temperature of 90 ° C and at a temperature of 40 ° C. 2F thoughtful handling Once you have determined that the PVC is consistent, it is important to see what measures he takes to keep the product clean. Dust, dirt and grease can contaminate the sheet, making your printing effort a waste of materials, time and money. The number of transfers of PVC during manufacturing, packaging, warehousing, distribution and delivery has a variety of opportunities for the transfer of dirt. Therefore, it is imperative to ensure that the sheet is clean and easy to install. Your PVC manufacturer should wear gloves when handling the product to prevent dust from being applied during extrusion to the delivery shop, and should take packaging measures to ensure that the product is protected after it arrives. The PVC you choose should be shipped with a protective sheet on the pallet. When you remove the sheet from the pallet, keep the top protective sheet. When taking the sheet, always wear a pair of gloves to prevent the exposed skin from coming into contact with PVC. The grease will appear on the sheet after printing, making your sheets unusable and reducing productivity. Another option is to order PVC coated with a thin, transparent protective polymer film that is applied to one side of the sheet. This film needs to be easily removed before printing to keep the surface uncontaminated. 3F reduces static electricity Static electricity is another obstacle to maximizing PVC printouts. Static electricity in the sheet can make it difficult for the ink to adhere to any substrate, affecting how the ink is sprayed onto the paper. The first step to avoid static problems is to purchase products that remove static electricity during the manufacturing process. Second, you can control the static electricity in the inkjet printer by monitoring the humidity and using the humidifier on cold, dry days. In order to further release the static electricity in the sheet, a deionization device built in the printer or purchased on the market is used. As an additional protection, a string of wires can be hung to allow the sheet to enter before contacting the sheet. Run under the print head. Keeping PVC sheets clean and static-free is two easy ways to increase the efficiency of PVC printing, but ensuring that you work with manufacturers that offer consistent products is the key to maximizing quality and yield.
