Advantages of corrugated carton flexo printing

Flexo printing is the best way for corrugated box printing. This has reached a consensus at home and abroad. Flexo printing corrugated boxes have the following advantages:

● Flexo printing can both print the field version and print the cable version

Foreign countries tend to use white paper (white cardboard coated or 80g/m2 single-sided coated paper, offset paper) E corrugated cardboard, with 100 lines / in printing high-grade corrugated paper color boxes, printing in all types of coarse corrugated generally are 80 lines/in, usually 40-60 lines/in. Printed cable prints on kraft paper are generally not printed in three primary colors, and the number of screens should not exceed 60 lines/in.

● Flexible version is flexible

The flexible version is flexible and elastic, and can compensate for the thickness error and surface unevenness of the corrugated cardboard during the printing process to make the ink layer more uniform, thereby improving the printing quality.

●Flexographic printing belongs to light pressure printing

Corrugated cardboard due to corrugated, so that the pressure during the printing process is uneven, corrugated high pressure, corrugated light pressure is low, sometimes corrugated low printing plate is not in contact with the ink can not be printed out of the phenomenon. Offset and gravure cannot overcome this defect, resulting in severe signs of corrugation. The flexo printing is light pressure printing. After the compression deformation of the printing plate, the corrugated paperboard can be well contacted. The high corrugated area will not produce severe marks or even crushing due to excessive pressure.

● Flexo printing can use water-based ink

Flexographic printing uses a metal anilox ink transfer system that can use aqueous inks. Water-based inks are used to print corrugated paperboards, which require only light contact with the corrugated board. Waterborne inks are almost completely absorbed.

●The flexo printer has a simple structure

The corrugated paper box has a large area and the length of the paperboard can reach 2-3m. If offset printing is used, the equipment is huge and operation and maintenance are difficult. The structure of the flexo press is simple and the four rollers are made into one color group. After the diameter of the roller is increased, the mechanical performance and stability can be improved. Loading, adjusting and cleaning are very convenient.

● Can be combined with other processing equipment to form a linkage production line

Because of its simple structure, the flexo printing press can be produced in conjunction with other processes. Nowadays, most corrugated board printing presses are combined with creasing machines and slotting machines for on-line production. It is used for indentation, slotting, die cutting and gluing. The box making and counting device together form a printing production line, which can directly print the corrugated box once.

Modern corrugated carton flexo printing mainly has two production processes: post-printing and pre-printing. Post-printing is the output of the corrugated board, which is then printed on a sheet-fed flexo printing machine. Slotting, die-cutting and other processes can be completed with printing. Pre-printing is to print the corrugated cardboard firstly before the production of corrugated cardboard, then send the printed noodle paper to the tile line to produce a color-faced corrugated cardboard, and then convey the next process to form a box. Among them, preprinting is the most widely used process in today's corrugated flexo printing.
