"Soft" and "Color" printed on corrugated cardboard

Recently, flexo printing technology has been widely used for printing corrugated paper. Its use in the color printing of corrugated boxes is even higher.

It is reported that 98% of corrugated cartons in the United States mainly use flexographic printing technology for color printing, and 85% in Western Europe. The color printing of foreign corrugated cardboard is mostly E-type corrugated cardboard with white paper surface. The number of high-grade printing screens can reach 120 lines/in, and four color printing can be realized. Printing on corrugated board, the prominent advantage of flexographic technology is that its elastic deformation can compensate for the thickness error in the printing and the unevenness of the surface, avoiding the unevenness of the printing ink color. In addition, the low printing pressure and the use of water-based inks are also one of the reasons for good printing results.

The industry's process of color flexo printing on corrugated board is summarized as: graphic design → image processing → plate making → printing → die cutting → box making. Experts should be reminded to pay attention to the following issues: avoid full-page printing; text should be clear; ink color saturation; consider the actual ink parameters, dot gain and other parameters; consider the different lines of the dots, the width of the flexo printer, and the printing slotting machine, and Different materials and pressure effects and so on.
