What are the printing processes? This is a question that many pre-press novices often have little understanding of. In fact, with the development of printing technology, printing processes have become more and more abundant. Usually, "post-printing" refers to the post-printing work, which generally refers to the post-processing of printed matter including gluing (coating), UV, oil, lamination, hot stamping, embossing, mounting, binding, cutting, etc. It is multi-purpose For promotional and packaging printed matter.
The scientific name is hot press transfer printing, referred to as thermal pad printing, commonly known as hot stamping and silver hot stamping. It is a method of hot stamping metal foil onto printed matter with the help of a certain pressure and temperature. There is also cold pad printing.
Features of hot stamping: Metallic luster, magnificent, creating strong contrast in the printed image.
Scope of application: Suitable for very prominent text or logos, mostly used in samples, greeting cards, invitations, wall calendars, desk calendars, etc.
Note: With the convex or embossing process, it can be more obvious; in addition to gold and silver, the colors that can be used include colored gold, laser light, spot colors, etc. to choose from.
It is ultraviolet glazing, UV is the abbreviation, which relies on ultraviolet irradiation to dry and solidify the ink. UV is usually a silk screen printing process, but now there is also offset printing UV.
Definition: A special process of fully or partially curing UV photocoat on the surface of printed matter
Features: It can present a variety of artistic special effects on the surface of printed matter, making the printed matter more beautiful
p>
Types: thickened UV, frosted UV, colorful UV, glass beads, colorful powder, etc.
Scope of application: Book and periodical mounting, envelopes, covers, desk calendars, high-end packaging, handbags Wait
Note: If you use UV on film, you need to use a special UV film, otherwise the UV will easily fall off, bubble, and open glue. The effect will be better when combined with special processes such as embossing and hot stamping
The scientific name is imprinting. It is a process that relies on pressure to cause local changes in the printed object to form a pattern. The metal plate is corroded and becomes a pressing plate and a negative plate for lamination. It is divided into two types: cheap ordinary etched version and expensive laser embossed version.
Embossing
Definition: Using a convex template (positive template) to press the surface of the printed matter into a three-dimensional relief-like pattern (the printed matter is partially convex, making it It has a three-dimensional effect and creates a visual impact. ) is called bulging;
Features: Can increase the three-dimensional effect
Scope of application: Suitable for paper above 200g, high-gram with obvious sense of mechanism Heavy special paper
Note: The effect will be better when combined with hot stamping, local UV and other processes
Debossing
Definition: Use concave template (negative template) to pass pressure The function is to emboss the surface of the printed matter into a relief-like pattern with a concave feel (the printed matter is partially dented to give it a three-dimensional effect and create a visual impact.) It is called embossing
Features: Can increase the three-dimensional effect
p>Scope of application: Suitable for paper above 200g, high-gram weight special paper with obvious sense of mechanism
Note: The effect will be better when combined with hot stamping, local UV and other processes. If the concave template is heated Acting on special hot melt paper will achieve extraordinary artistic effects.
Embossing
Definition: Using a metal roller with engraved textures to pressurize and leave a full texture on the surface of the paper
Features: Use ordinary copper paper It achieves the effect of special textured paper, which is highly decorative and unique in style.
Categories: Fantasy stone, beaded guilloché, coarse cloth pattern, fine cloth pattern, crescent pattern, gold sand pattern, felt pattern, leather pattern, pear pattern, Caixuan pattern, stripes, gold thread pattern, Laini pattern, pottery Texture, braided pattern, gold leaf pattern, bamboo silk pattern, etc., are numerous in number and space is limited. The above are commonly used textures
Scope of application: Book and periodical mounting, envelopes, covers, desk calendars, high-end packaging, handbags, etc.
Also called beer, the pronunciation of Guangdong is "turtle", which means die-cutting. The die-cutting process is a forming process in which a special die-cutting knife is made according to the design requirements of the printed matter, and then the printed matter or other substrate is rolled into the required shape or cut mark under the action of pressure.
Definition: A process that uses steel knives and steel wires to form templates and process printed matter into the required shape under pressure.
Features: Can produce special shapes and enhance expressiveness.
Scope of application: Suitable for products using paper above 157g as raw material, such as self-adhesives, trademarks, gift boxes, related printed artworks, etc.
Note: Try to avoid patterns and lines that are close to the pallet and cutting lines, as it is easy to exaggerate the pallet and cut errors.
Just put a layer of glue on the paper first, and then sprinkle gold powder on the glue.
It is a spring-like object, mostly made of plastic. It is generally used on the spine of wall calendars and notebooks to connect pages.
A layer of transparent plastic film is pressed on the printed paper, including crystal film, glossy film and matte film. They are called differently in many places and are not environmentally friendly.
Definition: A processing technology that covers the surface of a printed matter with a plastic film and uses an adhesive to heat and pressurize it together to form a paper-plastic printed matter. (Cover a thin layer of polyethylene film on the surface of the printed matter)
Category: There are two types of coated spectroscopic film and matte film
Features: The surface of the product coated with light film is bright and expressive. Strong, mostly used for product prints; the surface of products covered with matte film is non-reflective, elegant, and mostly used for image prints
Scope of application: Paper over 200g must be used when there are creases in solid color parts Laminating process
Note: Paper under 128 grams is easy to curl due to different surface tensions on both sides after being coated on one side; the color saturation of the printed matter will be slightly reduced after being coated with matte film;
< p> Also called needle thread and dental floss, it is to press a semi-connected line on the paper, which usually appears at the opening of the packaging.It means to make a hole in a piece of paper or N pieces of paper according to the size as required. There is a special punching machine.
It is to apply a layer of glue to the paper, and then apply a layer of velvet-like substance to make the paper look and feel like velvet.
