Flexographic printing is a revolutionary version of flexography which utilizes a thermal imaging camera to obtain high-resolution images of intricate surface areas of products. This old-fashioned method of flexographic printing can now be utilized on almost any sort of substrate, such as polypropylene (PP) plastic, corrugated cardboard, fiberglass, cellophane, paper, and metal. The flexographic printing process employs high-performance, quick-dry, moisture-free, semi-clear inks. These inks are usually recovered from the inks used in photography processes such as printing, digital flat printing, flexography, and CID printing. The inks used in flexographic printing have a superior reproduction of colors, shades, lines, and other visual qualities.

Flexographic printing is particularly useful for creating attractive labels for packing and display purposes. This method can produce flat labels, which can be laminated to enhance the product's storage stability. The laminated label has a much longer life span than its unsteady counterparts. Also, it is an economic choice because a single flexographic printing plate can print thousands of labels.

In the flexographic printing process, a series of flexible roll (usually made of strong, flexible material) is pushed down through a heated roll head. The roll head generates friction between the roll and the coated plates, which force the ink into the recesses of the plates. After the ink has been uniformly distributed across the plate surfaces, the process is finally ended by exposing the roll to a special air compressor. The compressed air removes excess moisture, thereby allowing the printed images to dry very quickly.

A large variety of flexible PVC material is used for the flexographic printing process. Some of the most commonly used materials include polyvinyl chloride (PVC), polyester, natural rubber and carbonless PVC. The PVC is widely used because it is highly versatile. It is commonly available in rolls of both thin and thick size, which makes it easier to handle. Also, it has very good heat resistance capability, which means that the printed images can stay on the substrate for longer periods of time without getting damaged. Also, the PVC is easy to handle and clean, and it is ideal for use in conjunction with other printing processes.

In addition to the PVC, a common additive for the flexographic printing process is inks. The most popular inks are water-based inks, which offer excellent printing properties. They are capable of printing on different substrates such as plastic, metal, cardboard and wood. However, if the substrate is not suitable for the ink, such as clay, stone, ceramic and porcelain, then the inks have no effect.

The other important equipment for flexographic printing process includes a vinyl cutting press and letterpress machines. Vinyl cutter machine is used to cut out the required vinyl banners. On the other hand, the letterpress printing machines are used for preparing the final product. Letterpress printing presses include offset presses and industrial presses. These equipment are required for producing large quantities of labels for retail shops, packaging companies, departmental stores, etc.

In addition to the machines, you will also need a large number of rolls to produce the stickers. The most common and widely used rolls are 100% cotton paper, polyester, vinyl and aluminum foil. The pre-cut stock is usually made from polyester and aluminum foil. However, if you want your labels to be printed in special colors, you will have to purchase rolls of certain colors separately. If you don't have a roll printer, you will also need to print paper in various colors and black and white images for the final labels.

You can use the Flexography machine for producing different types of stickers. There are some popular stickers that include manufacturer's labels, sales brochures, product tags, etc. Flexography can also be utilized to print bar codes on products and other commodities. As mentioned earlier, the Flexography process can produce different kinds of prints, such as vinyl films, foil stamps, metal prints, etc. These images are developed using special techniques and tools, such as dye sublimation, flexography, digital ink rollers, and aluminum oxide inks.
