There are so many types of finishings and coatings that can make a print piece unique, so how are UV coated pieces different from the rest and how does it work? Keep reading to find out!

what is spot uv coated printing?

Spot UV coating is a print finishing option that can make your piece stand out. Essentially, it is a layer of clear gloss that gets printed over the top of your finished piece. This layer of gloss can be printed onto certain areas of the printed piece so that it gives a unique raised look to those spots.

How does spot uv coating work?

Our new Duplo Spot UV Coater/DCC 810 is a premium machine that makes spot uv finishing easy for designers and operators. The process begins by printing a full CMYK version of the file on an offset or digital printer. Once the job has finished printing, the pages get moved over to our Duplo for spot coating to be applied on top of the CMYK printed pages. In order for the Duplo to know where the Spot UV will be places a grayscale version of the file must be created. See how to create this file here.

The Duplo uses registration marks, QR codes, and barcodes to read a grayscale spot uv file (as seen in the below image). These marks tell the machine where to put the UV coating, to ensure precise placement every time.

Our Duplo machine knows how much gloss to put on a specific area of a printed item by the grayscale percentage of the object. For instance, if a circle has a grayscale percentage of 100% then the Duplo would read that as an area which would receive the maximum height of spot UV. In contrast, an object that has a grayscale percentage of 30% would have less height.
