Monochrome offset printing machines, as the name suggests, can only print one color at a time.
There is a certain difference between the selection of printing supplies for monochrome offset printing machines and multi-color offset printing machines. Multi-color offset presses usually require a higher selection of consumables, while monochrome is relatively more random.
In fact, the choice of printing consumables, from the perspective of cost, quality, cost performance, etc., should be more careful. Here is a brief talk about the choice of consumables for monochrome offset presses.
First of all, the only consumables that need to be purchased frequently at Feida are the nozzles. The mouthpieces are generally available in three thicknesses: thick, normal, and thin.
Under normal circumstances, these three thicknesses can be adapted to a variety of papers. Even with the thinnest nozzle skin, there is no problem with the thickest paper. Of course, during the paper feeding process, there may be cases where the paper can be sucked. It can be compensated by adjusting the height of the nozzle and the amount of inhalation.
Personal recommendation: ordinary mouthpieces, a relatively wide range of adaptation. Prices range from 0.3 yuan to 1 yuan per piece.
Take the brush wheel on the cardboard table, the belt, you need to choose according to the actual situation. It is recommended that the hair wheel should be smaller, because the smaller the deformation of the wheel is relatively smaller, which makes the stability of the paper more stable. good.
The choice of ink is very important. There are many manufacturers of peony in monochrome machine ink. Peony is one of the most cost-effective inks, and its performance is also one of the most stable in ink. Old brands, big brands, trustworthy. Another reason is that there are relatively many suppliers of peony, price competition is fierce, and profits are limited. This is one of the reasons why many printing companies have been following Peony ink for many years. Other inks are also recommended here: Tianjin Tiens, Shanghai Huaxing, Hangzhou Hanghua.
There are several types of ink accessories: ink additives, detacking agents, varnishes, etc.
Under normal circumstances, the use of varnish is more expensive, cheaper, degreaser and ink additives are relatively more expensive, in the case of unavoidable ink additives can be used instead of debonding agents, the effect is similar.
Wetting powder is more critical. Many printers believe that the more wetting powder, the better the printing effect, but it is not. The more the amount of wetting powder, the more easily the PS plate is burnt out. Although the moisturizing powder has certain ability to prevent dirt, it is not omnipotent. It mainly makes the water fine and stabilizes the surface tension of water. Will cause water to smash.
The revision paste, the revision solution, and the revision pen are selected according to different situations. It is recommended to use the revision paste for the printing room and the revision pen for the machine.
The price difference between the cleansing paste and the cleaning solution is quite different, and there is a way to save both materials. When wiping the plate, we try to use the sponge instead of the cloth head. The sponge has a strong water absorption function. You can use a bucket and put the appropriate water on the side of the machine. Soak the sponge in the finish every time. After a long time, the cleansing paste remaining on the sponge is also incorporated into the water. I have seen a printing factory, a machine, and only use two boxes of Jiezheng cream a month, and reuse the water in the bucket every day. When you use the water to smell bad, you are willing to dump it.
Although this is very economical, it is appropriate to consider it from a health perspective.
The selection of the ps version depends on the specific situation. Some enterprises only need the regenerative version to complete the operation, while some enterprises do not need to use the Huaguang version. In the case of a large amount, it is necessary to use a good plate, and the amount is small, only a few thousand pieces per batch, and the recycled version is also a very good choice. After all, the printing quality requirements for monochrome printing presses are relatively low. Blankets are still recommended to use some better, such as the United States Dico, Italian Vulcan, are the leader in the blanket, normal use, can be replaced in a few months, quite cost-effective. Of course, it is not excluded that some companies print thick paper all the year round, and it is easy to crush the blanket, and only use the domestic rubber.
There are two kinds of reducing agents: one is to clean the reducing agent, the reduction effect is not very good, basically a bottle of 10 dollars. One is a strong recovery reducing agent, a paste, the effect is good, the price should be between 60 and 80. This depends mainly on the price of the blanket. Sometimes a new bottle of strong reducing agent can be purchased with a new blanket.
There are also some auxiliary materials, recommended here: idling protection agent, calcium removal agent, anti-skinning agent, car wash water, etc. Calcium removal agent is used to remove the surface crystallization of the rubber roller. The effect is good. After use, the material on the surface of the rubber roller can be effectively removed. If the surface of the rubber roller is crystallized seriously, it needs to be removed and wiped with toluene. The use of anti-skinning agents can effectively save car wash water. This is not recommended. If the downtime is more than 4 hours, it is recommended to wash the glue.
The choice of dusting depends on the condition of the printed matter. Need to be finer, or the grain is coarser, depending on the amount of ink, the thickness of the paper, and the smoothness of the surface of the paper. If you print a plate of paper, choose an environmentally friendly, non-toxic powder.
