Varnishing in flexography is a finishing process that is typically used on paper products such as prints and posters to give them a smooth finish.
Two steps must be completed in order to seal the paper, and then a bright light must shine over it to remove dust and other impurities. Vearnishing can be tricky, but there are a few key factors to remember if you want your prints to look their best.
First, make sure you apply the sealant correctly. Too much or too little will result in a sloppy finish.
You should also adjust the shine level based on your product’s specific needs. Prints with too much shine will look artificial, while prints with too little shine will have faded images.
Finally, avoid varnish that contains solvents or chemicals; these will damage the print.
