Spray approach with the substitute?? Complex offset printing ink additives useful application all through the country, in the substitute spray approach achieved some achievement, and in the total printing method and the total (total) Print high quality and Following printing approach, the accomplished a lot more satisfactory final results to the consumer. On the other hand, in accordance to feedback, blankets piled in the ink and occasionally some aspects of the difficulty.
HC printing network With Dusting Procedure option?? Compound Offset printing ink Additives in the practical application across the nation, in the option Dusting Technologies has produced some achievements, and the whole printing approach and the overall (total) print top quality and finishing approach, the attained satisfactory outcomes in contrast to the consumer. On the other hand, according to feedback details in the ink accumulation Blanket Factors of some problems sometimes, specifically on the issue now collate and analyze and response the following.
Suggestions (one) print to the 4000 or so, started to heap Mexican phenomenon, but the ink transfer machine technique and the plates had been not abnormal habits.
(2) print to far more than 5,000, occurred heap ink, otherwise normal.
(3) print 9000, almost everything regular, no heap Mexican phenomenon.
Analysis Ink resulting heap principal causes are: raw supplies, environmental circumstances and other variables. Mexican phenomenon heap particular law, in the event of difficulties, if cautiously observe their advancement trends, adjustments progress, associated to the place and extent of damage print good quality, by way of the phenomena can be assessed and the following conclusions.
one. Clockwise heap Mexico Pile roller, stack plates, stack Blanket , From prime to bottom of the heap Mexico, can be named “3 groups” phenomenon. The major bodily properties triggered by the two person, 1 ink drying also fast in itself or added too many dry oil (particularly red dry oil), it will not only consequence in ink crust, but also raised ink texture and thicken 2nd, the ink pigment particles coarser, heavier texture and so on.
two. Counterclockwise heap Mexico “3 groups” phenomenon started in the blanket of the reactor ink phenomenon is a overall performance by the two substances caused interrelated, a single paper surface strength, and 2nd, the viscosity of ink and adhesive. Of program, if the ink viscosity in the press on the greater worth, then a distinct story. In the course of this issue occurs, the surface power of paper and ink more substantial viscosity, viscosity in contrast to the decisive issue is the surface strength of paper.
Caused by ink emulsion ink heap, the first affected are printed model and the ink on the inking roller, and then to the two directions, on the fountain, the down to the blanket on and then transfer to the paper . Minor will not impact the ink emulsification, who will have a heavy blanket under the pile, the pile roller phenomenon, if the ink emulsion ink is as well critical to be broken construction, resulting in not printing. However, often ignored is neither minor nor a severe progressive ink emulsification. No apparent indicators of adjust started, when moisture articles increases steadily and savings to a specific extent, they will create up small by small, the ink on the blanket. At the very same time and then progressively transfer from the inking roller to transfer ink technique, the phenomenon is slow roller on the ink layer thickness, but the effect is still not reached the degree of ink transfer and transfer. At this stage, if not pay interest to alter the ink-water stability, its root leads to to misjudgment, inappropriate measures, the accident-susceptible.
Ink additives on lead-cost-free powder ink accumulation problem blanket, suggestions and relevant details to be much more complete, then via the demonstration to draw acceptable conclusions, primarily based on the actual implementation of merchandise features to boost the predicament.
Two proposals (1) take away the parts connected to the press on the residual dust. If you use powder-free ink additives, need to eradicate.
(two) normal substitute Fountain Solution The same time, the elimination of sediment below the water tank, washing tank. Reverse improvement in the printing process is not only a “3 stack” the distinctive phenomenon, Fountain Solution Also have this phenomenon, but has not attracted people’s attention. .
