4-Color Printing |
CMYK halftone overlay for photo-realistic color reproduction |
Colorful patterns, portraits, landscapes, gradients |
Print a spot-color base first for light colors on dark paper, otherwise the color will look gray |
|
Spot Color Printing |
Direct Pantone color printing for absolute color accuracy |
Brand logo colors, large solid color blocks |
Use spot red for bright red; 4-color overlay easily causes orange or purple tint |
| Surface Treatment |
Matte Lamination |
Laminates a foggy film onto paper |
Nearly 90% of mid-to-high-end packaging |
Scratch-resistant, wear-resistant, great hand feel — highly recommended |
|
Spot UV |
Applies gloss varnish locally on matte film for light-dark contrast |
Highlights logos, patterns, text |
Avoid large-area UV (easily traps dust and looks dirty); use small, precise UV areas |
|
Embossing/Debossing |
Presses paper to create raised or sunken patterns with molds |
Minimalist logos, textures, borders |
Deep embossing is not recommended for paper under 200g, as it easily causes edge cracking |
| Foil Stamping |
Hot Stamping |
Transfers metallic foil onto paper via heat and pressure |
Metallic texture, laser effects, logos |
Fine-line stamping is the most difficult; Hanlong uses high-precision copper molds to avoid broken lines |
|
Cold Stamping |
Bonds foil with adhesive without heat |
Large-area stamping, special paper |
Cold stamping has lower gloss than hot stamping; suitable for large backgrounds, not fine text |
| Structural Process |
Die-cutting |
Cuts paper into shapes with steel rules |
Special-shaped boxes, windows, inserts |
Sharp right corners risk scratching hands; Hanlong uses rounded corners (R-angle) by default for user-friendliness |
|
Lamination |
Bonds face paper to gray board |
Hard gift box production |
Glue must be thin and even, otherwise “orange peel” wrinkles will appear after drying |
