The tips in the process of self-adhesive label printing, should use so big! _ printing equipment
Summary introduction: small make up to introduce the five tips in the process of self-adhesive label printing, very useful! ! 1, printing from light agent to remove white dot the author previously encountered such a problem: when printing a batch of urgent delivery of live parts, raw materials surface dust is too much, but since there is no time change the raw materials, and the dust cloth is finished using the takeaway: small make up to introduce the five tips in the process of self-adhesive label printing, very useful! ! 1, printing from light agent to remove white dot the author previously encountered such a problem: when printing a batch of urgent delivery of live parts, raw materials surface dust is too much, but since there is no time change the raw materials, and also ran out of dust cloth, cause when printing the white of large area. In order to solve this problem, the author adopted a way: not commonly used system of a field, the raw material on the surface of a printing of the UV light agent, and then according to normal process printing ink. Due to the first printing UV from light agent has to leave the dust sticky on the surface of the raw materials or override, back when the printing ink basically is not white spots. And, because the UV light agent were very light in color printing ink will not affect the behind of the hue. But doing so will greatly improve the production cost, thus can be used for emergency only, not as a conventional solutions. 2, in addition to electrostatic interference opportunely the author also have encountered such a problem: the north some stickers printing factories winter film materials, frequently material rewinder not neat and printing machine operating system crash phenomenon. The factory USES is Lin type division LPM300 intermittent stickers printing machine, equipment performance is stable, but why the situation of the operating system crash? Later found the culprit is the printing film materials produced by a large number of static electricity. Due to electrostatic interference device operating system often freezes and does not work, but also lead to thin film material winding. But production task urgent at that time, no time on the equipment installed in addition to electrostatic device, so the author suggest that add a two humidifier in the workshop, to improve the workshop of relative humidity, greatly eliminate the electrostatic effect on the equipment and materials, the final production to run smoothly. 3, local adjustment paste version of the double-sided adhesive thickness, achieve ideal effect in the non-drying label printing printing process often appear local printing color too deep or too shallow, at the moment can by adjusting the local version of the double-sided adhesive thickness method to solve, and do not need to back out of the film print. Particular way is: if the local printing color too deep, the region plate below the double-sided adhesive can be removed, equivalent to reduce the local printing pressure, printing color will be lighter. Likewise, if a local printing color too shallow, can be in the area of plate below to add a layer of tape, this is equivalent to increase the local printing pressure, printing color can be deepened. Adjustment by local pressure in this way, often can solve some problems and can avoid the trouble to film, plate making and also save the plate. 4, in addition to press paper round mark opportunely during the non-drying label printing, paper press paper round of tend to material extruding stain, factories are having to material widened ( Generally more than the actual printing width 10 mm) , let the pressure roller pressure at the edge of the material, to avoid the marks in the surface of the finished product label. But this method is a waste of raw materials, in fact, the author recommended the pressure roller surface with a layer of adhesive material ( Paper, thin film materials, it is recommended to use PET material, the effect is best) , can greatly reduce or even eliminate pressure impressions of the wheel on the material surface. After using this method, we can use the minimum width of raw material printing labels, greatly reducing the waste of raw materials. 5, the solution of the coated paper popping once, the author in the use of inclined back press printing in large area field label material foaming phenomenon. When the material is coated paper stickers, it is strange that bubble is in the adhesive material on the surface of material. The author also have ever had before material foaming phenomenon, but bubbles appear in between surface material of adhesive materials and adhesives, the phenomenon of blisters on the surface material or meet for the first time. Analysis was thought that the bubble is due to the adhesion force for separating surface material. Inclined back label printing in the printing field labels easy to generate large stickers phenomenon, the main reason is ink viscosity big or printing pressure. But if the ink is transferred to the state of thin, at the same time after printing to minimize the stress status, or occasionally, the phenomenon of the adhesive material surface bubbles. This shows that not only is ink and printing pressure problems, that there will be other what reason? Finally, the author found the reason, is the resin version of the deformation. Due to the resin version placed after a period of time will lose water and deformation, is usually characterized by around the middle sag, cock. When using a piece of the old resin version, such as plate if not used directly, after warm water immersion on the surface is flat, but in fact, around the low or middle, high. Inclined back label printing machine adopt the way of flatten is flat, so will cause printing layout center sag have very strong adhesion force, so that the surface material layer of adhesive materials. After understanding to this situation, the author will resin soak in warm water for a long time, the resin version of fully absorbing water to recover the original shape; Then computer printing and foaming phenomenon disappears.
