Flexographic printing machines are a versatile and cost-effective choice for a wide range of printing applications. However, not all flexographic printing machines are created equal. When you’re in the market for a flexographic printing machine, it’s important to know what features to look for to ensure you get the best machine for your needs.
Print Quality
The print quality of a flexographic printing machine is determined by a number of factors, including the resolution of the print heads, the type of ink used, and the accuracy of the registration system.
– Resolution is measured in dots per inch (dpi). The higher the resolution, the sharper and more detailed the printed image will be. For most applications, a resolution of 600 dpi is sufficient. However, if you’re printing very fine lines or small text, you may need a higher resolution.
– Ink is another important factor that affects print quality. The type of ink you use will depend on the material you’re printing on and the desired results. There are two main types of ink used in flexographic printing: water-based ink and solvent-based ink. Water-based ink is less expensive and more environmentally friendly than solvent-based ink. However, solvent-based ink produces a more durable and vibrant print.
– Registration is the process of aligning the different colors of ink on the printed material. Accurate registration is essential for producing high-quality prints. The registration system on a flexographic printing machine should be able to accurately align the different colors of ink to within a few thousandths of an inch.
Speed
The speed of a flexographic printing machine is determined by the number of print heads and the speed at which the print heads can travel. The speed of a press is measured in feet per minute (fpm).
– Number of print heads The more print heads a press has, the faster it can print. Presses with multiple print heads can print multiple colors at the same time, which can significantly increase the speed of the press.
– Print head speed The speed at which the print heads can travel also affects the speed of the press. Presses with high-speed print heads can print faster than presses with low-speed print heads.
Versatility
Flexographic printing machines can be used to print on a wide variety of materials, including paper, plastic, metal, and fabric. The versatility of a flexographic printing machine is determined by the type of printing plates it uses.
– Flexographic printing plates come in a variety of shapes and sizes. The type of printing plate you use will depend on the material you’re printing on and the desired results. There are two main types of flexographic printing plates: rubber plates and photopolymer plates. Rubber plates are less expensive than photopolymer plates, but they are not as durable. Photopolymer plates are more durable than rubber plates, but they are more expensive.
Reliability
The reliability of a flexographic printing machine is determined by the quality of the components used in the machine and the level of maintenance the machine receives.
– Components The components used in a flexographic printing machine should be of high quality and durable. The machine should be well-built and able to withstand the rigors of daily production.
– Maintenance A flexographic printing machine should be regularly maintained to keep it running smoothly and efficiently. Regular maintenance includes cleaning the machine, lubricating the moving parts, and replacing worn parts.
