Tote bag printing skills

When printing white plate, copper paper, paper jam, kraft paper, due to the quantification of paper, therefore, the paper feed nozzle, the air volume of the paper feed portion should be maintained accordingly; the paper absorbent should replace the diameter, Thicker rubber ring; lar-regulatory compression spring can be replaced with a large diameter model to achieve the intravation of non-swing and smooth paper.


When printing whiteboard paper, the clearance of the offset printer double controller should be added accordingly, and the interval between the side gauge and the pre-prodrugal tongue and the paper panel is increased. Avoid multiple white sheets to block between the imprint cylinder and the rubber drum, form a "boring" problem.


The interval between the double control wheel and the paper feed roller cannot be less than 2 sheets of paper, and it is not more than 3 sheets of paper, otherwise the arched paper will park when the paper is passed; maybe the double paper has passed from the manner out of the manner. The controller is still not touched, and the purpose of manipulating double is not active.


In addition, two dust or insulators of two electric shockings, paper feed roller appearance and power control office should also be cleaned up in time, and avoid dual control system failure.


(2) Conditioning printing pressure


The portable paper bag often uses white sheet of paper with 250 ~ 400 g / m2, and the paper is relatively thick, and the conditioning of the printing pressure is quite demanding.


When conditioning, the center distance of the plate drum to the rubber drum is unchanged, and only the center distance of the imprint cylinder and the rubber roller is adjusted. When the printing is quantified of 250 ~ 450 g / m2 whiteboard paper, the center of the drum is 0.20 to 0.40 mm away. In addition, since the outer surface of the whiteboard paper is poor, its tightness is also good, there is no copper plate, so it is necessary to pay attention to the corresponding printing pressure. Conditioning the printing pressure, can also adopt an increase or decrease eraser bag




(3) Tissue well-printed color sequence, when tissue printing, in addition to considering the back of the back, you should pay attention to the following points.


(1) First printing the NET, the post-print line, and the field. When there is a four-color printing network, there is a text, a field pattern, and a line, in order to ensure the accuracy of the print, reduce the impact of paper scaling, should first print the merits, re-print line, field, and Ability to look for the main times, first difficult.


(2) First print deep color, then print the color. Due to the weakness of the light color ink, it is slightly imprinted when it is stacked, and it is not easy to find out that the printer is better.




(4) Avoiding the back of the back


Troll printing tend to have full field, simply forming the back of the back. Therefore, it should be used as much as possible to use the original bucket ink, properly add some to the adhesive, anti-adhesive, and do not add 6 # tone oil. Do not dry the oil when the weather is hot.


In addition, it can be solved by powdering. However, it should be noted that the powder can affect the outer surface gloss of the print, and the environment will be partially worn, and the offset printing machine is partially wear, sticky. Need attention is to correctly tissue printing. In order to avoid the back of the paper, the paper is dirty, and the text, line version, and then print the field version.


The top of the handbag printing plan is premiere in its convenience, useful, maintenance, and propaganda. In order to pursue the rationality of the planning function, the planner not only demands in planning, but also guarantees the post-printing process. Since the tote is used as an important item that shows corporate image, the quality of the print is directly affected by people's awareness of the enterprise. Therefore, in performing the need for handbag printing, it is necessary to grasp the necessary way, and ensure the exquisiteness and generous of the handbag.


The top of the handbag printing plan is premiere in its convenience, useful, maintenance, and propaganda. In order to pursue the rationality of handbag planning, planners not only need to plan up and down, but also guarantee post-printing workers.
