Varnish Coating Machine
what is Varnish Coating Machine?
Comprehensive varnishing machine is an important role in the production of print surface finishing equipment. Its main role is in the print surface coating (or spray, print) a layer of colourless transparent coating, drying to protect and increase the gloss of the print role. Comprehensive varnish machine can significantly improve the surface performance of the prints, improve the prints of abrasion, dirt and water resistance, so that the appearance of the prints of the effect of a thicker and fuller, more bright and vivid colours, thus enhancing the attractiveness of the prints and added value.

Product Applications
Packaging products
The comprehensive varnishing machine plays an important role in the surface finishing process of cartons, paper boxes and other packaging products. It can improve the abrasion resistance, stain resistance and water resistance of packaging products, making the packaging more beautiful and durable.
Books and picture albums
The varnishing machines are commonly used in the varnishing treatment of book covers, picture albums and other printed materials. Through varnishing, the surface gloss of these printed materials is significantly improved, and the colours are more vivid and bright, enhancing the reading experience and artistic effect.
Advertising and promotional products
In the production process of advertising and promotional products, the full-face varnishing machine is also an indispensable equipment. It can make advertisements and publicity products more eye-catching and improve the publicity effect.
Other printed materials
The varnishing machine is also suitable for the surface finishing of trademarks, calendars, large decorations, posters and other printed materials. After these printed materials are varnished, the surface is smoother and brighter, which improves the overall quality.
The process for varnishing paper of varnish coating machine
Preparation:
Check equipment: Ensure that all parts of the varnishing machine are working properly and there are no malfunctions.
Prepare materials: Check if the varnish (varnishing agent) is sufficient and adjust the varnish formula as needed.
Adjust equipment parameters: Set the speed, pressure, temperature, and other parameters of the varnishing machine according to the requirements of the printed material.
Load printed materials:
Load paper or printed materials: Neatly place the printed materials to be varnished into the feed device of the varnishing machine.
Apply varnish:
Varnish application: The varnishing machine evenly applies the varnish on the surface of the printed materials. The application method can be roller coating, blade coating, or spraying, depending on the type of varnishing machine.
Drying treatment:
Drying and curing: The printed materials after varnish application pass through the drying device for drying treatment. Common drying methods include hot air drying and ultraviolet (UV) curing. This process ensures that the varnish dries and cures quickly, forming a smooth and glossy surface.
Cooling and output:
Cooling treatment: Some varnishing machines are equipped with cooling devices to ensure that the printed materials reach the appropriate temperature before output.
Output printed materials: The dried printed materials are output through a conveyor belt or other means, completing the varnishing process.
Quality inspection:
Inspect finished products: Check the varnished printed materials to ensure their surface is smooth, without bubbles or defects, and meets the expected gloss and protective effects.
Clean equipment:
Clean the varnishing machine: After operation, clean all parts of the varnishing machine, especially the varnish application device and drying device, to prevent varnish residue from affecting the equipment.
