At present, the main problems faced by carton printing factories are long time for plate change, poor printing to cutting accuracy, poor die-cutting quality, excessive paper wool, too many and too large connection points, irregular trace lines, slow production speed, and scrap rate. higher. This article will answer the above questions one by one for the printing factory.
Problem 5: Irregular trace lines
Considering the needs of folding and gluing boxes, the carton must have a good creasing line. What’s more, when these boxes are running on the automatic packaging machine, the opening force must be stable and consistent. In this way, choosing the appropriate type of trace line is the basic element when die-cutting. According to the thickness of the paper, choose the height and width of the crease line, glue the appropriate crease line on the die-cut bottom plate, the crease can achieve higher quality and make the box easy to fold.
Problem six: slow production
The die-cutting speed of the die-cutting machine in many carton printing factories is relatively low, such as 2000–3000 sheets/hour, while the die-cutting speed of some printing factories can be as high as 7000–7500 sheets/hour. Using modern automatic die cutting machines, the operator can easily reach the highest production speed. Production speed is optimized by using tools recommended by equipment manufacturers. In addition, it can also make the product achieve high quality.
Problem 7: High scrap rate
The scrap rate of most printing plants is usually high. There will be some waste at the beginning of the die set-up, which can be reduced by using the proper tools and correct procedures. Waste products during operation are caused by downtime and paper jams. Correct adjustment and accurate tool preparation can reduce the waste rate. In addition, manual stripping can increase scrap rates and reduce profit margins.
