2.Gold / silver scalding. 
The scientific name is called hot pressing transfer printing, referred to as hot transfer printing, commonly known as bronzing, hot silver. 
Is to use a certain pressure and temperature to make metal foil hot stamping on the printing method, there is also a cold printing. 
Stamping characteristics: metallic lustre, magnificent, so that the printing screen produced a strong contrast. 
Scope of application: suitable for prominent words or logos, mostly for samples, cards, invitations, calendars, calendars, etc.

Visual shock). 
Features: can increase stereosyncrasies. 
Scope of application: It is suitable for paper of 200g or more, high-gram weight specialty paper with a clear sense of mechanism. 
Note: With hot stamping, local UV and other processes, the effect is better. 
4.Film mulching. 
Press a layer of transparent plastic film to printed paper, such as light film, dumb film, tactile film, etc. 
Definition: the process of covering plastic film on the surface of a printed material by using a adhesive that is heated and pressurized to bind it together to form a paper-plastic-in-one print.

Scope of application: 200g paper or more, if there is a crease in the solid color area, the coating process must be used. 
. 
5.Embossing. 
Definition: Full metal texture on the surface of the paper after pressurization using a metal roller with engraved lines.

Species: Stripe just ancient Laini pattern. 
Scope of application: book decoration, envelope, cover, desk calendar, high-grade packaging, handbags, etc. 
6.Die cutting (play steel knife). 
. 
Definition: A process in which a steel knife or steel wire is used as a template to process a printed product into a desired shape under pressure. 
Features: Can be shaped, enhance performance. 
Scope of application: Applicable to products with 157g or more paper as raw materials, such as stickers, trademarks, gift boxes, and related printed artwork.
