Corrugated carton problems need attention in printing
due to the color of the corrugated board itself is quite dark, so must be considered when choosing the color of the print to try to choose the color saturation, strong tinting strength of ink ( Such as big red) , or the color of the print and the color of hope can make a big difference.
corrugated carton that should be paid attention to in the printing problem two: avoid printing small text
as a corrugated cardboard box printing, considering from the effect of products, should determine its font size. 2 cm below the size of the text, generally in the distance more than 5 m almost can't see, this also loses the significance of publicity to promote the sales of their goods.
corrugated carton in the printing problems should be paid attention to in 3: avoid full printing
corrugated box full or around the printing graphic, in addition to the embossing roll on corrugated board has the effect of pressure of anhui, ink on paper and infiltrating effect, which will reduce the compressive strength of corrugated carton. Therefore, corrugated carton printing graphic as simple as possible, and try to avoid in the box on the printing graphic everywhere, not to mention the full version of the color.
corrugated carton in the printing & packaging problems that should be paid attention to four: avoid ribbon ( Same as the direction of corrugated cardboard machinery)
some printing & packaging designers because of a lack of printing process knowledge, design of the carton printing design has some horizontal gradient line. When printing, the printing pressure corrugated crushing. The cartons in the region of stress concentration will occur, and therefore the most easily broken.
corrugated carton five problems that should pay attention in printing: minimize printing pressure
in order to ensure the carton print quality, and reduce the influence of the strength of corrugated carton, try to small printing pressure and ink used as far as possible choose fast drying oil ink. Second, the printing surface and horizontal line indentation to keep more than 15 mm from the left, because the corrugated board be framed or machine line pressing plate of lower part is not fully accept ink, otherwise it will affect the printing effect.
corrugated carton should be paid attention to in the printing of question 6: keep the ink viscosity stability
ink viscosity is the main indicators need to be controlled in the corrugated board printing, it is one of the main factors influencing the state of the printing color. Due to the volatilization in the process of printing ink solvent, base viscosity will rise, in order to maintain the stability of the ink viscosity, should every half an hour ~ 1 hour and ink stabilizer, addition amount of 1% ~ 2%.
in printing problems should be paid attention to in seven corrugated carton: keep paper stable
in addition to the printing machine speed stability, the artificial paper placement to be fixed. For flatness bad board, to properly deal with, such as along the cardboard transverse pressure side ( Or both sides) Impreaaion nip. By hand delivery and so on various paper guide clearance for a cause, these are related to maintain an important link of the cardboard and stable operation, also & quot; Running version & quot; The phenomenon is one of the important methods. To keep the printing equipment in good condition. Want to emphasize here is keep the anilox roller and plate clean, clean is directly related to the printing effect. Anilox roll the relationship between the ink transfer performance, plate is related to printing, design the sharpness of the text.
corrugated carton in printing problems should be paid attention to in eight: maintain stability of the ink transfer amount
therefore, must be kept stable printing speed is balanced. Because the relationship between the ink transfer printing speed, balanced running, so can't fast and slow. To keep balance of paper, cannot occur every piece of paper. Only in this way can make the ink printing machine has a stable state of the ink, it is important to maintain the stability of the ink printing color effect.
corrugated carton in printing problems should be paid attention to in 9: minimize the overprint number
overprint, the more the more serious the compressive strength of corrugated paperboard.
