Printing and Finishing Techniques Overview (Complete List)
01. Four-Color Printing (CMYK)
A planographic printing method that uses the subtractive color mixing principle with cyan, magenta, yellow, and black pigments to achieve full-color reproduction. Features: The visual brightness of the colors is nearly linear, but it tends to result in an excess of neutral gray components in the printed colors.
02. Spot Color Printing
A printing process that uses inks other than the standard four (CMYK) to reproduce original colors. Features: 1. Accuracy: Each color has a fixed hue; 2. Solid Color: Capable of defining colors with solid ink coverage; 3. Opacity: Allows for effective solid covering; 4. Wide Gamut: Offers a very broad color gamut within specialized color libraries.
03. Screen Printing (Silk Screen)
A method where silk, synthetic fiber, or metal mesh is stretched over a frame, and a stencil is created using manual lacquer film or photochemical plate-making. Features: 1. Strong printing adaptability; 2. Excellent lightfastness and vibrant colors; 3. Suitable for large printing areas; 4. Thick ink layer with a strong three-dimensional effect and rich texture.
04. Hot Stamping (Foil Stamping)
Commonly known as "Gold Stamping," it involves transferring color foils or other materials onto paper to form text and patterns, or using heat and pressure to emboss various textures. Features: 1. High quality and precision, with clear and sharp edges; 2. High surface gloss, resulting in bright and smooth patterns; 3. Wide range of foil options with various color effects.
05. Frosted Printing (UV Frosting)
A process where a layer of transparent UV frosted ink is printed on a substrate with a mirror-like gloss, then cured by UV light to form a rough surface similar to ground glass. Features: 1. Exquisite patterns with a strong 3D effect; 2. Solvent-free with high solid content, causing minimal environmental pollution; 3. Fast curing, energy-efficient, and high production efficiency; 4. The ink film has excellent friction, solvent, and heat resistance.
06. Embossing (Pattern Embossing)
A technique that uses molds with concave and convex textures to deform the substrate under pressure and temperature, creating patterns for artistic processing of decorative packaging materials. Features: 1. Capable of presenting patterns and textures of varying depths; 2. Provides a distinct relief-like 3D effect.
07. Laser Engraving
A process that utilizes the interaction between a laser beam and matter to perform cutting, drilling, marking, scribing, and engraving on materials. Features: 1. No physical contact with the material surface; 2. Unaffected by the elasticity or flexibility of the material; 3. High processing precision, fast speed, and wide application fields.
08. Embossing (Blind Embossing)
A finishing technique that uses female (concave) and male (convex) molds to mechanically process the surface of printed matter for artistic effect. Features: 1. Environmentally friendly with no pollution during production; 2. Increases the richness and artistic quality of printed products; 3. Replaces traditional fonts or colors to showcase core content and emphasize specific areas.
09. Debossing
A technique where pressure is applied from the front of the paper to indent the surface. Features: 1. Applicable to a wide range of materials; 2. Can be combined with other printing techniques and processes; 3. Capable of expressing diverse 3D effects.
10. Lamination
Also known as "Gluing," it involves covering the surface of printed matter with a layer of transparent plastic film to form a paper-plastic composite finishing technique. Features: 1. Protection: Protects printed colors from scratches; 2. Increases the toughness of the printed product.
11. Varnishing (Coating)
The application of a colorless, transparent coating to protect the surface and increase gloss. Includes overall, spot, gloss, and matte. Functions: 1. Enhances lightfastness; 2. Increases heat/moisture resistance; 3. Beautifies the product.
12. Die Cutting
Cutting printed matter into pre-designed shapes using a die-cutting plate, allowing for non-linear and custom shapes. Functions: 1. Creates 3D or curved effects; 2. Enables exquisite custom shapes.
13. Flocking
Fixing short fibers vertically onto an adhesive-coated substrate. Features: Strong 3D effect, soft and luxurious feel, thermal insulation, and non-shedding.
14. Foam Printing (Puff Printing)
Using microsphere foaming ink applied via screen printing, then heated to obtain raised graphics. Features: Tactile, raised 3D effect.
15. 3D Lenticular Printing
Creating 3D spatial differences on a 2D surface using lenticular materials, viewable without 3D glasses. Features: Realistic depth and virtual reality effects.
16. Spot UV
Localized varnish cured with UV light to create glossy highlights. Classifications: Gloss, matte, frosted, colorful, refractive, and more.
17. Glitter Printing
Covering the surface with metallic flakes to create a metallic texture and luster. Features: Long-lasting color, ideal for festive decorations.
18. Refractive Printing
Using high-reflectivity materials with embossed lines to create shimmering 3D images. Features: Dazzling, luxurious, and highly three-dimensional.
19. Relief (Bas-relief/High-relief)
Creating recessed or raised shapes on a flat surface to separate them from the plane. Features: Combines planar and 3D artistic qualities.
20. Phosphorescent Printing (Luminous)
Uses luminous powder to achieve a cycle of light absorption and luminescence. Features: Non-toxic, non-radioactive, and safe.
21. Anti-counterfeiting Processes
Techniques used for security and easy identification of authentic products. Includes special inks, holograms, and unique patterns.
22. PVC/PET Printing
Printing on plastic materials like PVC, PET, or PP. Features: Excellent durability, water resistance, and transparency. Often used for high-end clear packaging.
23. Window Patching
A process of die-cutting a 'window' in a box and applying a transparent film. Features: Allows customers to see the product inside while maintaining protection.
24. Soft Touch Coating
Applying a special varnish or film that gives the surface a velvet-like, soft texture. Features: Premium hand-feel, anti-fingerprint, and elegant matte finish.
25. Fragrance Printing
Uses micro-encapsulated scented inks that release fragrance when touched or rubbed. Features: Interactive sensory experience for marketing.
26. Die-cutting & Creasing
Simultaneously cutting the shape and pressing the fold lines into the cardboard. Features: Ensures precise assembly and structural integrity of packaging.
27. Box Gluing & Folding
The automated process of folding and gluing the die-cut blanks into final box forms. Features: High-speed production with accurate alignment.
28. Cardboard Lamination
Bonding layers of different papers (e.g., printed face paper to corrugated board). Features: Combines high-quality graphics with structural strength.
29. Cold Stamping
Applying foil using UV-curable adhesive at room temperature. Features: High speed, compatible with fine gradients, and no heat required.
30. Textured/Patterned Paper
Using base materials that already have specific textures or embossed patterns. Features: Unique tactile appeal and premium aesthetic without additional processing.
