Description
Technical field
The invention belongs to printing technologies, and in particular to a kind of printing equipment.
Background technology
Intaglio printing product has many advantages, such as that layer of ink is thick and solid, level is abundant, three-dimensional sense is strong, printing quality is good, is mainly used for
Print exquisite color image, trade mark, decoration product, marketable securities and offset news etc..When intaglio press prints, in print cartridge
Top be equipped with for impression cylinder provide ink blotting roller, impression cylinder full space of a whole page by being contacted with blotting roller
Inking is scraped the ink of blank parts on the space of a whole page with doctor, leaves the ink of areas, then crosses paper (stock),
It is imprinted at the back side of paper by impression cylinder, the ink of negative area is made to be transferred directly on paper, it most afterwards will print through paper collection part point
Brush product heap or rewinding is good.
Wherein ink is by 20%~40% resin, 5%~15% pigment, 40%~60% organic solvent mostly
And 0%~5% the goods and materials composition such as auxiliary agent.Link stuff is adhesion resin, is the pass chain component part of ink, pigment and quilt
Print material is bonded in one piece, plays adhewsive action, and keep ink glossy.Pigment determines color category.Solvent dissolving resin is adjusted
Viscosity is saved, rate of drying is adjusted, improves the wetting action to printing material.Additive, which then rises, improves viscosity, weatherability, resistance to old
Change, increase the effects that gloss.
However at present when carrying out inking using ink, it often will appear ink layering, the phenomenon that even precipitating be precipitated, go out
Now one of the phenomenon is main reason is that the solubility of resin and solvent is uneven, especially with concentration viscosity greatly
When smaller ink, lamination is even more serious；And lamination can cause printing ink ingredient unbalanced, seriously affect printing
Quality.
