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 require a higher selection of consumables under normal conditions, while monochrome is relatively random. In fact, the choice of printing consumables, from the perspective of cost, quality, cost performance, etc., should be more careful.
1, the choice of ink
Monochromator inks use more peony manufacturers, peony is one of the most cost-effective inks, and its performance is one of the most stable inks. Under normal circumstances, the use of varnish is more and more expensive, and the price of detackifier and ink additive is relatively expensive. In the case of last resort, ink additives can be used instead of detackifier. The effect is similar.
2, wetting powder
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.
3.Ps version selection
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. The blanket personal is still recommended to use better.
4. Selection of dusting
Depending on the condition of the printed matter, it needs to be finer, or the grain is coarser. It depends on the amount of ink, the thickness of the paper, and the smoothness of the surface of the paper. If the paper is printed, it is necessary to choose environmental protection and non-toxic dusting.
