In life, printed products are indispensable daily necessities. They can be used not only in daily study and work, but also in the advertising industry. Therefore, the customer groups for printed products are quite wide. Because people have different requirements for products, if they want to show different product effects, the printing process will be diversified according to the needs of customers. So what are the printing processes often used by printers? What are the characteristics of each?

Inkjet printing is a commonly used printing process. This printing method has the characteristics of high work efficiency, convenient and fast pattern conversion, and lower cost than screen printing. It does not require too complicated processes when printing. Generally The data to be printed will be recorded on the electronic computer, which can be converted at will. For example, when the pattern is printed on the edge of the tile, the pattern can be replaced quickly. When using screen printing, it takes time to adjust. It is more convenient and faster than screen printing, and the work efficiency is very high.

Anodized aluminum is generally available from Taiwan Qunguang S07 (silver) or G07 (gold). The longer the distance between the seams, the better, and the width of the seams should be smaller. In addition, the anodized aluminum separation layer should not be too loose. The viscosity of the glue layer should not be too high, otherwise it will cause hot stamping to fly or pull back; cross line-add a register cross line to the hot mouth and the body part of the hot stamping; the hot stamping pressure is based on the touch with no obvious uneven feeling as the standard ; When hot stamping the sample, a hot stamping film should be prepared, and the pattern should be hooked (0.01mm lines) to check whether the partial pattern is missing; air pressure before printing-press down the anodized aluminum scraps to avoid the phenomenon that the printing ink cannot be transferred After the printing is completed, the printing die cutting and embossing will be completed within 24 hours: the height of the relief should not be higher than the height of the die cutter. Generally, the height of the relief after pressing is the same as the height of the die cutter. But the thick cardboard above 450G should be made separately. Die-cutting technology: Cross-cutting knife is used for die-cutting paper materials. It is used to die-cut paper products. The cut has a mirror effect, smooth and dust-free. The blade of the cross-cutting knife is stable and durable. Ruled die-cutting knife is used for die-cutting of gum materials, because gum materials need to use a sharper ruled knife to die-cut the rebound rubber hardness. When the distance between the die-knives is less than 8mm, Select sponge rubber with a hardness of HS60 (solid type); when the distance between the die cutters is> 8mm, choose a sponge rubber with a hardness of HS25 (corrugated cardboard) or HS35 (cardboard, 35% compression rate); When the distance between the cutter and the steel wire is less than 10mm, the arch sponge rubber with a hardness of HS70 should be selected; when the distance between the die cutter and the steel wire is more than 10mm, an arch sponge rubber with a hardness of HS35 should be selected. ; The cutting position of the die-cutting knife should be arch rubber with hardness of HS70 to protect the joints from being broken. The sponge rubber is installed at a position less than 1mm from the two sides of the die cutter blade, and cannot be installed close to the blade body; the sponge rubber should be about 1.2mm higher than the blade edge, and the indentation line should be adjusted according to different hardness. The calculation method of the indentation line: the thickness of the indentation line A ≥ the thickness of the cardboard (c), the width of the indentation line B = 1.5c + 0.71mm, the indentation line size is selected according to the calculation result A × B (mm); used for corrugation Method for calculating the indentation line of paperboard: the thickness of the indentation line A ≥ the thickness of the corrugated cardboard (e), the width of the indentation line B = 2.0e + 1.0mm, and the size of the indentation line is selected according to the calculation result A × B (mm); West Before the installation of the CITO creasing line, clean the bottom plate of the die-cutting machine with cleaning liquid. The bottom plate should be free of impurities, especially oily substances, which cannot help to adhere firmly. Be careful not to use oily liquid for cleaning. Shear or hand cut the indentation line of the same length, and put the indentation line on the steel wire; peel off the protective tape, start the die-cutting machine, and press once, and then press it firmly to make it sticky. Make a short press and stay for about 1 minute; turn on the board and pull out the bottom plate, remove the indentation line glue, and then use the indentation line to 502 high-strength glue or glue lines on both sides of the reinforcement indentation, so that its displacement. After production, use a sharp scalpel to oblique both ends of the indentation line in the paper passing direction to make the paper pass smoothly with the combination of the indentation line and the steel wire: steel wire height die cutter height-paper thickness; steel wire thickness ≥ paper thickness.
